A war’s been raging since 1963. That’s the year Winchester brought to market its now famous 300 Winchester Magnum. That introduction was, I’m guessing, retaliation against Remington’s 1962 release of its equally famous 7mm Remington Magnum. Each cartridge is today the most popular magnum in its caliber, raising the question: Which is the best all round hunting cartridge?
Now, you 300 Weatherby Mag. fans don’t jump in here and spoil the argument or I’ll let the 300 RUM lovers counter. Size matters, so let’s stick to the two older magnums. (Or read this article for another take on magnums.)
To engage this 7mm RM vs. 300 WM argument you have to be willing to pick at nits because, bottom line, both cartridges (and many other magnums like them) are winners. Either will neatly terminate deer, sheep, elk and larger game so long at the shooter delivers the right bullet to the right spot. Those are always the deciding factors: right bullet, right place. Given that, I would happily and eagerly hunt anything with either cartridge — even charging brown bears. Well, I wouldn’t be eager to face a charging brown bear, but I’d trust either cartridge if I had to — so long as each was spitting a long, heavy, controlled expansion bullet.
Regardless, if I had to pick just one of these for all-round hunting, it would be the 7mm Rem. Mag. by a nose. In a nutshell, here’s why: given equal rifle mass, optimum bullet Ballistic Coefficients and Muzzle Velocities in each caliber, the 7mm RM will shoot flatter, drift less and recoil with less brain jarring recoil than the 300 WM. Let’s run a quick ballistic comparison and see the tale of the tape. We’ll pretend both rifles weigh 8-pounds as shot. We’ll zero both at 250 yards, load both to maximum muzzle velocity and fire both in a 10 mph right angle breeze. Ready, aim, fire!
Here are the relative recoil levels from both 8-pound rifles in the above scenario:
Recoil Impulse Recoil velocity of rife Free recoil energy
7mm Rem. Mag. 3.5 lbs. per sec. 14.07 fps 24.6 foot-pounds
300 Win. Mag. 3.89 lbs. per sec. 15.64 fps 30.4 foot-pounds
Astute readers will notice a few things from these numbers:
- Contrary to popular belief, the heavier bullet does not drift less in the wind. Wind deflection is determined by a combination of B.C. and MV, not just weight. Weight is only a part of B.C.
- The heavier, larger caliber bullet delivers more energy at all ranges despite starting with a slower MV. The higher B.C. of this 210-grain .308 bullet helps it resist air drag, enabling it to retain more of the energy it started out with.
- The 7mm (.284-inch) bullet drops less at all ranges even though the .308-inch bullet has a more efficient, minimum drag B.C. This is because the MV was 200 fps faster.
- The 300 WM kicks slightly more. If you’re recoil sensitive…
- None of this matters to the elk. If you think 150 f-p impact energy will spell the difference between venison on the pole and a lost cripple, you might be interested in a bridge I’m selling in Manhattan.
Our current fad for long range shooting makes these studies in ballistics fascinating, but at “normal” hunting distances, neither cartridge has an appreciable advantage over the other. Deciding which you prefer comes down to levels of recoil, downrange energy, bullet drop and bullet drift, none of which are significant unless you plan to be throwing at targets beyond 500 yards.
Both cartridges fit through standard length actions, both maximize performance in 26-inch barrels but do fine in more convenient 24-inch tubes. Both are chambered in just about every hunting rifle made, including wonderfully affordable models like Mossberg’s Patriot as demonstrated here. Both are loaded with a wide variety of some of the the best bullets in the world and both are widely distributed and easily found. You can find .284 bullets from 100-grains to 180 grains, .308 bullets from 100- to 230-grains for handloading but — and this is a significant but — factory loads may throw you a curve!
WARNING: In factory loaded ammunition, you’ll be hard pressed to find 300 WM ammo with bullets heavier than 180 grains. Most brands offer 170 to 175-grain options in 7mm RM. That changes the ballistics significantly in favor of the 7mm and might alter your plans. If you are planning to shoot factory ammunition only, check back here for Part Two of this cartridge comparison blog. Factory load options might change your mind.

May 1, 2016 at 3:20 PMThis comparison could come down to which one you shoot better. If minute-of-deer/elk accuracy is there, it is not going to matter since the two cartridges are so close to each other in aspects that matter. If I had to choose, I would go with the 7mm Rem.
roy burns says
May 4, 2017 at 3:13 PMWhy not compare bullets of close grains so he mess up with the 300mag why not use 180 grains against 7mm 168 grains to be fair and l reload thank you rtb
Ron Spomer says
May 13, 2017 at 2:46 PMI’ve found it most illuminating to compare bullets of similar B.C. in various calibers, but it’s informative to also compare those of similar weight, in which case the narrower caliber almost always wins the ballistic battles, given similar muzzle velocities.
Chris says
November 3, 2017 at 5:58 AMBut in this case the velocities would not be similar. The 300 WM is obviously going to have higher velocities with similar weights. I agree. Apples to apples is to compare loads of similar BC and SD.
Jesse says
April 22, 2018 at 4:34 PMThanks for the info. New hunters like myself usually just buy factory Ammo. Also most people can only afford one nice rifle. (For ourselves)Especially if we have to get our wife/gf or a child/teenager a rifle as well. These articles are great. I find that the experienced hunters and they do know what they are talking about and they have good intentions however they are a lot louder and make more noise and make it seem like all hunters are experienced pros. But we are not. Many of us hunt a few seasons in a lifetime. Or have a few great experiences and move on for various reasons. So I thank the writer of this article for simplifying it for people like me. I think that was his intention. The writer assumes the pros understand that hand loads can achieve higher achievement. Thanks
Tom says
September 6, 2018 at 10:10 AMRon Spomer, what do you mean by narrower caliber?
Ron Spomer says
September 6, 2018 at 3:38 PMCaliber is a unit of measurement much like inches or centimeters. 30 caliber means the diameter of the hole is .30 of an inch across. So a narrow caliber would be .284, .277, .264,.257, etc.
Travis says
October 11, 2018 at 4:57 PMMost people shoot factory ammo. Hornady has the 165 sst from the 300 going 2235 fps at 500 yards with 1830 energy. The 154 sst in 7mm is going 2242 with 1718 at 500.
Ron Spomer says
October 12, 2018 at 3:22 AMYou are smart to compare downrange velocities of your preferred ammo choices and memorize trajectory curves. You can make bullet selection in most cartridges to favor minimal drop or minimal drift or maximum energy.
Mike L says
January 21, 2019 at 7:04 PMYou should try Barnes ttsx 165gr round for your .300wm. Here’s the link you can compare the 7mm mag 160 gr with the .300 wm 165 gr. closer comparison. The .300 wm is a hard hitter, but remember they both use the same case as the venerable 375 H&H
Ron Spomer says
January 26, 2019 at 3:51 PMYes, Mike, same parent case, but differences in overall length. 300 WM body a bit longer.
Ken says
June 19, 2017 at 2:49 PMExactly what I was thinking I don’t know a single person that hunts long range or would ever shoot long range with a .300 win that go over 180g lol
Ron Spomer says
June 20, 2017 at 5:32 PMKen, of course, as a serious long-range shooter, you know the details, but most “ordinary” hunters just use what’s commonly available in factory ammo, and the most commonly used bullet weight in 300 WM is 180 grain. My intent was to inform readers of the performance of that. As to your implication, yes, certain 210 to 225-grain .308 bullets in the 300 WM will match or exceed performance of 170- to 180-gr., high BC bullet in the 7mm RM. The key is BC and MV. Match those and you match trajectory/wind deflection. The heaviest bullets will then retain the most energy. Recoil with them will also be highest. Many shooters are concerned with recoil.
Chris says
November 3, 2017 at 6:00 AMMost long range hunters using 300WM are actually using 200+ gr loads. They have higher BCs and reloaders can usually get the same velocities from these loads as the factories load the 180 gr loads. A reloader can get a 200 gr Accubond going 2950+ fps out of a 24″ barrel.
richard thompson says
May 28, 2019 at 11:37 PMMeet myself, or any member of any long range forum, or, come to that, any military sniper .
Nearly all of us use bullets in exceess of 210 grains, and I don’t know of any military that uses a 7mm Mag…..
Dan says
June 23, 2019 at 10:11 PMUS army used the 700 chambered in 7mm Rem mag as a sniper weapon.
Mark says
December 15, 2017 at 2:43 PMOr to be “fair” use a 180 in 7mm and a 180 in .308! The 180 gr 7mm bullet makes it so one sided to the 7 mag it’s not even funny. But like many have already stated, it doesn’t matter. Both are awesome and just pick whichever you like more or shoot better :)
Bruce says
December 16, 2018 at 1:44 PMI agree with you Roy, equal grains would provide a better end result.
Steve says
October 12, 2019 at 11:51 PMWhen comparable bullets are talked about here 168. 7mm to 180 30 cal…the 7 goes on by the 300 pretty quickly..and retains a lot more energy..just saying..
Dennis Owen says
October 28, 2017 at 4:42 AMThis is an apple to oranges example. And frankly I’m surprised the author used a 210grn bullet in the 300wm instead of a 180grn or even closer a 165 or 175 grn bullet. As he said bullet drift is not as big of an issue as velocity and B.C. I can prove that a 180 grn bullet out of a 300wm will exceed a 7mm substantially. And yes I have hundreds of chronograph and ballistics tests to prove it. I’m getting real tired of this which one is better than the other. It all boils down to what ever suits the particular shooter’s fancy. Not to mention ease of reloading or access to ammo, and overall cost effectiveness. I have often considered doing a 7mm/300 wm set up. But for me the 300 wm came out on top. The reasons and list is long, and at this point not important. But the point I’m making is that is what I chose for me. Opinions are like noses. Everybody has one.
Chris says
November 3, 2017 at 6:02 AMTo accurately compare cartridges the apples to apples comparison is to compare velocities with loadings of similar BC.
Kevin says
March 15, 2018 at 6:50 AMI am replying to Denis. Thank you. I am tired as well. They are both great rounds, BUT…
The .300 with a heavier bullet carries much more energy, much further PERIOD. AND THAT ENDS THE 800 SHOT DEBATE.
(Apple’s and Oranges)
But THE 7mm is has within 300 a much better flight in wind (drift) and for those on a budget might be a better option.
If your reloading things change a bit.
However, the not withstanding the drift of the .300 one must consider the recoil of the .300.
By no means am I anti 300 but they are apples and oranges they are both excellent rounds it’s like the debate between the 7mm and the 30 ought 6.
The 300 is more expensive to run than the 7mm the 300 is better at long distances the 7mm in my opinion seems to be more accurate inside of 400 yards in Wind is cheaper to operate and has less recoil.
Both are excellent rounds.
I cannot say thank you enough for your comment on apples and oranges cuz they actually are.
Simply in my opinion if you can handle a little extra recoil and the added expense a 300 is great if you need the extra distance.
However the 7 millimeter in my opinion I find will perform better closer in but that’s my opinion.
A great debate is the 30 ought 6 versus the 7 millimeter or the 300 versus the 375 H&H thanks for your post and I’d love your comments on my reply my best…
Happy Hunting to all and be safe.
Phil Weber says
May 2, 2016 at 12:16 AMThank you for an excellent article. I am a simple man of 79. I have a wide range of guns but only one hunting rifle, a 1903-A3, .30-06 I bought from the NRA in 1958, unmodified. I have brought down my share of Whitetails in northern Minnesota, usually with a 180 grain bullet. I would have enjoyed a more exotic experience, owning a wide variety of heavy duty calibers you frequently explore. But my professional career did not take me in that direction. No sheep, moose or bear hunting in Alaska, not even elk or antelope in Wyoming. But I have always enjoyed the writing of those who have. As a boy, my dream was to own a Marlin .45-70 for hunting in Alaska. Now I find out from my brother-in-law who lived in Fairbanks for 40 years, and a 47 year veteran fire helicopter pilot-friend currently based in Soldotna, AK for the fire season, the vast majority of Alaska natives use only a .22-250 with a V-Max 55 grain bullet. So, following your theme of it’s where you put the bullet that counts, does a .22-250 deserve consideration along side the magnums you have discussed? I’m skeptical but open minded.
Ron Spomer says
May 2, 2016 at 5:33 PMPhil: Sorry you didn’t get to make your dream trip to AK. Life has a way of limiting our options. Yes, many, perhaps most, far north natives employ 22-250 Rem., 223 Rem. 243 Win, the old 222 Rem. for collecting bush meat, including moose. I’ve heard and don’t doubt they’ve taken grizzlies with these, too. Completely doable, but problematic for the visiting sport hunter. The kinetic energy carried by lighter bullets minimizes internal tissue destruction. In my experience a .224 to .243 varmint bullet that is slipped behind the shoulder into the heart/lungs breaks up dramatically, tearing tissues in an area about the volume of a softball , perhaps volleyball. Tougher, controlled expansion bullets penetrate much farther to create a longer, narrower wound cavity. If either wound is atop the heart, it ruins the major arteries supplying blood to the rest of the body. This can render an animal unconscious in as few as two seconds. To whatever degree blood flow is disrupted by any bullet, the animal, regardless of size, sooner or later dies via oxygen starvation of the brain. Extrapolate that bullet energy to ever larger bullets and you see the potential for more tissue destruction and potentially faster demise. The mistake many hunters make is assuming bullet energy performs much like a boxer’s knockout punch, so the bigger and faster the better. But bullets don’t act like broad fists, which knockout because they shock the central nervous system. Any bullet, even a lowly .22 LR, that strikes the spinal cord from about the withers forward to the brain can kill the largest animal instantly. This does not mean the .22 is an optimal grizzly cartridge. Yes, with perfect shot placement, virtually any cartridge/bullet can terminate big animals, but common sense suggests size and power increases commensurate with critter bulk, especially if your time afield is expensive and limited. If you get a decent chance at your game at a less than perfect angle, you want a bullet capable of reaching the vitals. Someone living cheek to jowl with moose every day can await the perfect chance. On a 9-day hunt, you and I probably cannot. As for “stopping power” (grizzly charge, etc.) bullet size and velocity can make a significant difference, but not as much as many believe. No bullet fired from a shoulder-held rifle is capable of knocking back or even slowing down even a small grizzly. Breaking a leg can help, but don’t expect a heart shot to do the job. Sometimes a significant body hit with a big bullet can discourage and turn an attack, but as many have learned the ahrd way, only a central nervous system hit can ensure dead-right-there. As a famous African elephant hunter once told me “Unless you put the bullet into the brain, it doesn’t matter if it’s 100 grains or 1,000 grains. It won’t kill him. So you might as well use a 375 you can shoot without flinching.”
Zack says
May 12, 2017 at 11:16 PMWow, thank you for making it simple.
Dale Noah says
January 28, 2018 at 1:03 PMThat adds a significant aspect to the debate! Thanks
Kevin says
March 15, 2018 at 7:00 AMRon,
Exactly – That’s what a .375 H&H is for and is also the smallest legal required African round. Adding my two cents as an emergency backup a handheld Ruger 50 or a Ruger sr40 is a great savior tail just in case you could not have phrased your article or that post that I’m replying to just now better.
You’re almost paraphrasing the two to three argument as to it going in and tumbling the hopeful tumble to hit something important Theory.
Excellent comment the only thing you left out at the end was the moral is cya backup weapon. Lol.
cugeno says
July 28, 2018 at 7:07 PMThere are some African jurisdictions that will allow the 9.3×62 (.366 caliber) for big game, as well — but yeah, that .375 is the minimum in most places.
Navaratna Rajaram says
July 19, 2019 at 12:14 PMIn hunting dangerous game like grizzly, I would rather be overgunned than undergunned. A lesson my late father (a tiger hunter) stressed was never wound a dangerous animal. For grizzly or brown bear I would go with .375 Magnum or even a .416 Rigby. This way you have plenty of margin.
Ron Spomer says
July 19, 2019 at 1:33 PMNever hurts to err on the side of bigger so long as you recognize that no shoulder-fired bullet has sufficient power to stop an enraged bear. One can drive a 500-grain bullet carrying 4,000 f-p energy completely through a big bear or even a little one without stopping it. More power and more wound channel diameter through heart and lungs does not stop the brain and running gear from continuing to function for several seconds. Long enough for bear to extract his pound of flesh. The only sure stop is a hit to the central nervous system, and that can be done with remarkably small projectiles carrying limited energy. As always, shot placement with a bullet built to stay in one piece and reach the necessary spot is the key. If you can shoot, say, a 308 Win. with a hard, controlled expansion bullet capable of breaking and penetrating through any bone on a big bears frame, that could be a better option than, say, a 505 Gibbs because you are likely to 1. Not flinch. 2. Recover from recoil. 3. Get off multiple, aimed shot more quickly. If one chooses the biggest and baddest, one MUST train to operate it properly, and recoil recovery/follow up shots is an important part of that. Regardless what you choose, I hope you never have to use it to stop an attack. Oh, one more thing: it is possible and probable that a big enough bullet that misses the CNS could still dissuade a bear from pressing its attack. This is much of what John Pondoro Taylor addressed with elephants while developing his theories about KO factors. A near miss of the brain with a sufficiently large bullet carrying X-value energy could stun or turn an elephant from a charge while a lesser X-value energy bullet would not. Applied to heart and lungs, however, this doesn’t work. This partly explains why so many bears, buffalo, etc. have taken multiple shots to the body from big bore “elephant” cartridges and kept on coming.
David says
February 3, 2019 at 6:16 AMI dont think BC Weight or Velocity are ways to compare to calibers that are different. The proper comparison would be to shoot a bullet from each of the same Width and Length ratios. In that even the one with the heavier weight would have the higher BC but only if the velocity was equally increased in proportion to the ratio of difference between the WL. As you can see without testing the higher velocity smaller bullet would have the edge but that would be negated by the extra weight of the larger bullet. In the end the graph would not show this until way down range. So in the end up close the 7mm has the edge and later on down range the 300 comes out on top at first thought but as stated who shoots game over 500 yards or reloads for hunting at that range or practices at that range even less likely. So in the end the recoil comes into play as the deciding factor and I have to say that I have never remembered recoil after a kill shot using guns up to 416 rigby and in the winter with a heavy coat during hunting season I may attribute that lack of memory to but I think it more about the excitement.
I think the calibers are so equal in performance and commonality that little remains a factor in making a decision. I say buy both. I like higher velocity at down range staying supersonic but again that is more of a long range accuracy factor for military or competition both of which are not the focus of this conversation. I always lean toward the heavier larger caliber when it comes to killing animals. Larger hole is the one real difference. Trauma is about the same if the smaller lighter bullet is traveling faster but again they are so close.
Magazine fed allowing higher BC bullets is a factor but they both have that as an option as well.
Tom Murphy says
May 16, 2017 at 2:03 AMTom,. I enjoy all of Mr. Spomer’s articals. I’m a deer Hunter from Texas, I hunted with a 25:06 for around 27 years. Come across a deal on a m77 300 WM used only for over 10 years. Have a back neck so I got 700 SPS in 7.08, man it,s great. Thanks Mr. Spomer
David says
May 25, 2017 at 8:57 PM7mm Rem Mag vs. 300 Win Mag
1)) Load each of them with the very ‘maximum’ amount of powder each case will safely hold, and also with exact same type of powder.
2)) Load both of them with exact same bullet grain weight(150, 165, or 180 grain, etc.) an example is both of them with a 150 grain bullet, and also same bullet type.
Then I ‘do’ know the 300 Win Mag will have more velocity, being more FeetPerSecond than the 7 mm Rem Mag.
But I would also like to know, in the scenario I mentioned above, please also compare which cartridge will have the ‘best’ Ballistic Coefficient, Energy ft/lbs, flatter shooting, etc.??
This is a fair comparison that I would like to see done. Thank you. David

Mike richter says
November 13, 2018 at 12:41 AMHere’s how I see it I have two pretty much identical model 700 bdl Remington rifles actually three one is a300 win mag one is a 7 mm,Remington magnum and one is a 25_06 Remington using 120 grain bullets in 25_06 ,,140 grain in 7mm magnum and 180 grain in the 300 I’ve shot many deer with all of them if you get good bullets placement dead deer is the result Trajectory out to 500 yards on my shooting range seems about identical ,I know this because I’ve done this kind of shooting more than most ,we ,my friends and I used to put up one by one blocks of limestone out at the 450 mark I can tell you the 300 moves the rocks a lot more ,that being said one of my buddies came over one day with a 8 mm Remington magnum WOW I was impressed to say the leaste it would knock those blocks of solid limestone six to eight feet the 300 would roll it over the 25_06 made dust fly the 7mm more dust but that 8 mm magnum with 220 grain hornady hand loads was absalutetly way more powerful
Navaratna Rajaram says
July 18, 2019 at 4:08 AMMy experience is limited. I have shot two elks, one with .375 H and H, 270 grain and another with a 7mm 175 grain. Both were one shot kills. Both with shoulder shots. I don’t believing in taking a shot of over 200 yards. Both were well placed shots.
Ron Spomer says
May 25, 2017 at 9:53 PMFirst a clarification, David. The cartridges do not have a BC, the bullets do. In most cases you can get about 200 fps more velocity from a 300 WM than 7mm RM, so the 300 would win. At some distance, however, the more ballistically efficient bullet would take over. If we zero at 250 yards and shoot the Hornady 178-gr. .308 ELDX (BC .545) at 3200 fps and the Hornady 175-gr. .284 ELDX (.675) at 2,900 fps, at 1,000 yards the .308 would drop 231″ to 237″ for the .284. Drift: 67″ vs. 56″, Energy: 1023 vs. 1129. Yes, the.284 retains almost 100 f-p MORE energy due to its more efficient shape. This energy won’t matter a whit to the animal hit. Not that anyone should be targeting game at that range. Also, it’s unlikely you can use the same powders to get maximum velocity in each different cartridge.
Roger Duford says
June 30, 2017 at 3:44 PMA friend of mine went to Canada this past fall, wasn’t able to take his 7 mag because of Canadian regulations on caliber size. Had to take his 30 06 instead. So depending on where you like to hunt or go could end this debate
Ron Spomer says
June 30, 2017 at 9:51 PMIt’s always wise to check local regulations on legal calibers/cartridges and rifles. I doubt, however, that Canada disallows any 7mm magnums. I’ve hunted up there many times with various calibers and cartridges including .257, .277 and .284 (7mm) magnums. Your friend might have been misinformed by his outfitter. Many outfitters have strong preferences in calibers.
Dave says
October 8, 2017 at 3:40 AM7 mm rem mag is common here in Canada. Your friend may have run afowl of the 5 round (4 magazine + 1 chamber) limit for centre fire rifles however. You can shoot .338, 45/70, .50 cal sniper rifles if you want. 7 mm rem mag and 300 win mag are mostly western Canadian rifles where longer shots are normal. In the east, though these big magnums are becoming more popular, 30-06 rules but still many hunt with 30-30, .308, .303 British, .303 Savage.
Colin says
December 5, 2017 at 10:12 PMHey Dave, that’s not entirely true. There’s some areas (southern Ontario from what i hear) that have maximum bullet diameters. I’m guessing it has to do with population density and complete idiots making laws, mainly the latter. Every province has different laws, just like the states, but I agree that I can’t imagine there’s any province where they’d have an issue with a 7mm but allow a 30 cal.
Dave says
October 9, 2018 at 2:06 AMCorrect. The notion that Canada restricts calibre for big game is straight bs.
Navaratna Rajaram says
April 26, 2019 at 1:34 PMI have used 7mm remington magnum in Canada, no problem. I have shot everything up to and including elk with 175 grain factory load. properly placed it is entirely satisfactory. The maximum range was 160 yards. I refuse to take a longer shot.
David C. says
October 3, 2017 at 8:08 PMIn southern Ontario you cannot hunt with a bullet with a diameter larger than .275”, so in this case you wouldn’t be able to bring the 30-06. I’ve never heard of a 30 cal minimum law or regulation in Canada.
L Burton says
July 2, 2017 at 7:10 AMRoger Duford
As an Alberta, Canada resident I can tell you there is no such thing as Canadian regulations on caliber size other than you must be above .223 for big game.
Most of my hunting friends shoot from .243 to .375 H & H for big game in Alberta. Your friend was misinformed by someone re the regs.
L Burton says
July 2, 2017 at 7:11 AMRoger Duford
Sorry. Above.23, not .223
Colin says
December 5, 2017 at 10:18 PMNot in Manitoba. Keep in mind every province is different. In Manitoba, we just have to use a centrefire rifle for big game hunting. “A centrefire rifle of .23 calibre or less is not recommended” (2017 mb hunting guide) but is legal.
Dan says
August 7, 2017 at 8:42 PMMr Spomer I am getting ready to buy a 7mm mag. There are so many to choose from. I really like the model 70 extreme weather. It weighs 7.4 pounds. After scope rings sling and shells it would weigh close to 9 pounds. Do you think that’s too heavy for all day carrying in the woods. Thanks
Ron Spomer says
August 7, 2017 at 9:28 PMDan: Well, it would be for me these days. I like to think my 9-pound penalty days are behind me, especially since I long ago discovered my 6-pound rifles are just as field accurate as my 9 and 10. I know the trend is toward rifles the size and weight of small howitzers, but I also know I can hit out to beyond descent ranges any game I need to with my light rifles, so what’s the point of the mass? Not many agree with me, but I formed my opinion after hunting with literally dozens of rifles of all weights and sizes. All of my sheep and goats but two have been taken with 6-pound and lighter rifles out to 400 yards. No misses that I can recall. Many elk, caribou, moose also with the light rifles, and more than a few coyotes, Coues deer, etc. Seriously, I’m a light rifle convert of the highest order. Heavy rifle accuracy theory is one thing. Productive hunting is another. But you need to do what feels right to you. If interested in light, check out Rifles Inc, New Ultra Light Arms, Kimber Montana and Barrett Fieldcraft for starters.

December 22, 2017 at 4:09 PMRon, those are all great manufacturers, but their rifles aren’t cheap. What’s the downside of instead picking up a Tikka Superlite in 7 RM, using some of the savings to put good glass on it, then using the rest of the savings for a nonresident elk tags? I’d appreciate leads for any good reviews of the Tikka.
Ron Spomer says
December 22, 2017 at 5:12 PMNelson, you’re in luck. There are more inexpensive, accurate rifles on the market today than ever in history. I’ve not worked with the Tikkas, but have heard great things about them. I’ve shot Sauer 100s, Ruger Americans, Mossberg Patriots and Winchester XPRs that all grouped factory ammo MOA or less. I’m guessing you can find something that’ll work for you.

January 26, 2018 at 9:48 AMHi Nelson
I shoot a Tikka T3 hunter in 7mm rem mag with a VX6 3-18 on it. I am based in New Zealand and use it on tahr and deer. It’s light, accurate, and I can shoot all day with the suppressor on. Would recommend to anyone.
MG says
August 13, 2017 at 2:51 PMRon, nice article.
I recently was in the conundrum of picking either a 300 win or a 7 Rem. I ended up going with a 300 win chambered with the NSWC reamer (more freebies than Sami, developed for military to shoot 220 smk). I chose the 300 due to the wide range of loading options and due to the fact that I can easily purchase ammo on any continent in the world with the exception of Antarctica.
My current handload is the hornady 225 eld (g1 BC of .777) seated at 3.680 (0.020 off lands) running 2958 FPS with an ES of 6 fps. This load shoots 0.25″ regularly. With this bullet weight and velocity the kinetic energy is 4359 ft lbs! Also, on paper (I realize this can be wildly different in the real world, this load is still traveling 1122 fps at 2000 yards! This performance is mind boggling to me but I will never realize it’s full potential.
After achieving these results, I am abosolutely delighted choosing the 300 win.
Ron Spomer says
August 14, 2017 at 12:13 AMMG. Wow! Accurate rig. Glad it’s working well for you. Other readers might be puzzled by what auto-correct did to your words, so allow me: “More freebies than Sami” means MG’s NSWC reamer cut more free-bore in the chamber (before contacting the rifling) than the SAAMI (Sporting Arms and Ammunition Manufacturing Institute) standard. This enables him to seat those long Hornady ELD-X bullets. By the way, MG, I wasn’t aware Hornady had a 225-gr. .308 ELD bullet. The heaviest I can find on their website is the 220-grain with a G1 BC of .650. That’s still pretty impressive. And the group size! I’d be tickled to get that with one of my .22s or 6mms. You’re a lucky shooter. Happy shooting.

August 18, 2017 at 1:29 AM7-mag can’t go wrong. Took down a oryx NM. At 435 yards animal when down without 2nd round. (Shot placement) Cow elk last year at 320. Shooting 162 grain SST. Both hunts were done by my 15 year son. This was after many rounds at the range. Gun, wheataby van guard scope vortex 4x16x44 BDC. 300mag had to much recoil! As far as the old man I will stick with my 30-06… can’t go wrong! Good shooting.
MK says
September 9, 2017 at 2:10 AMHello Ron. I am looking at picking up a kimber montana in 300 win mag. Out of the box it weighs about 6 3/4 lbs. About 2lbs more than my current kimber adironack in 7mm-08. If i purchase this rifle i am going to put a vx-3 4.5-14×40 on it making the overall weight with sling right at about 8lbs. I was looking at similar remingtons and winchesters and they weigh between 7 1/2 – 8lbs out of the box in pretty much every caliber from S/A to L/A. So my question is, is in your opinion is saving a 1 1/2 – 2 lbs in a magnum rifle really worth it – in things like felt recoil, carry ability, price etc. Thanks.
Ron Spomer says
September 9, 2017 at 3:10 AMMK: Sav ing weight on a magnum depends on how you plan to use it. If you’re going to be carrying it all day on, say, an elk hunt, then yes. If you’re going to stand hunt or make short forays from the truck or horse, then probably not. I’m a light rifle nut and have hunted with 300 WSMs weighing less than 6 pounds. Recoil is nicely controlled by the right stock configuration. This idea that a rifle lighter than 8 pounds isn’t accurate is a bunch of hooey. I shoot off packs, boulders, bipods and tripods with deadly accuracy as far as 450 yards with sub 6-pound rifles, regularly.
Jake says
October 4, 2017 at 8:12 PMHello Ron! I am looking at purchasing my first rifle but am debating between the 7mm Rem Mag and the .30-06. I will be hunting from 100-600 yards and hope to shoot out to 1,000+ in a few long range shooting competitions for fun. I do plan on reloading since I know that it will be necessary for optimal accuracy but am stuck as I have heard great things about both calibers. Which do you think would work the best from me?
Ron Spomer says
October 11, 2017 at 3:59 AMJake, you’ll find better long range performance in the 7mm Rem. Mag. The game you shoot, however, won’t know the difference. Good luck.
Chris says
November 3, 2017 at 5:57 AMI think that’s a questionable claim. The 7mm RM is not proven to be better at long range than the 300 WM. They can push loads of the same BC at about the same velocity. Its a wash when comparing factory ballistics or reloading data but it’s been my experience that most 7mm RM factory loads actually fall short of listed velocity when chronographed. This is what I’ve seen and I’ve also seen many incidents posted online. For example, looking at a review of Hornady’s 162 gr Precision Hunter load for 7mm RM on Midwayusa one reviewer only got 2815 fps and the listed velocity is 2930. Another midway review for Hornady’s 200 gr Precision Hunter 300 WM load got 2908 fps with a listed velocity of 2850 fps. The 162 gr 7mm Mag load and 200 gr 300 WM load have the same BC.
This is just one example but matches my experience with the two cartridges. I find that rarely does an actual chronographed 7mm RM load actually meet the listed velocity while the 300 WM usually matches and sometimes even exceeds listed velocity. Reloading data matches this observation. A reloader really can’t beat factory ballistics for 7mm RM. A reloader can usually exceed factory 300 WM by 100-150 fps. Just look at Hodgdon’s data for both cartridges. That tells you all you need to know right there. The 7mm RM isn’t actually generating the listed velocities from 24″ barrels and you have to load it to max pressure to get there. You can load the 300 WM to well over 3100 fps with 180 gr loads and you can usually exceed 2900 fps with 200-208 gr loads with a variety of different powders.
Ron Spomer says
November 3, 2017 at 11:50 AMChris, you are sure right about listed velocities and actual. I’ve found most factory loads fall short of claimed MV, and some by as much as 400 fps. Reloading manuals’ velocities do not accurately reflect what every rifle/handloader will achieve with those recipes, either. Barrel length, chamber size, twist rate and more alter MV. Same goes for listed bullet BCs. In an ideal world every shooter/hunter would chronograph his/her loads and know actual average MV, but that isn’t going to happen. Next best option is to test for drop at 300, 400, 500, etc. yards in oder to develop accurate trajectory curve. Whether any individual rifle/load “beats” another isn’t nearly as important as the shooter knowing it ballistics and knowing how to shoot it effectively. Some 7mms exceed some 300s and vice versa. My intent in writing this and similar articles is to start readers thinking, experimenting and testing rather than accepting conventional “wisdom”. You, obviously, have been doing a fine job of that. Thanks for your input.
Mikal says
December 16, 2017 at 2:41 PMRon,
Can you explain why you say you will find better results with a 7mm than the 300 wm in a long range conversation with both using 180grain bullet.
Ron Spomer says
December 18, 2017 at 3:06 PMMikal, I sure can. In any given bullet weight, the longer, narrower one will be most aerodynamically efficient. It minimizes air drag, thus maximizes retained velocity. That is why a 180-grain .284″ (7mm) bullet will performa better at long range than a 180-grain .308 (300 WM) bullet (this assumes identical form factors, i.e. both bullets have same shape. You can’t get aerodynamic efficiency from a flat-nose or round nose compared to spire point boat tail.)
Stephen Bennett says
October 29, 2017 at 4:17 PMSeveral celebrated gun writers have said the 7MM with 150 grained bullet kills better than the 175 grained bullets.
Chris says
November 3, 2017 at 5:40 AMI’ve always found that people tend to overstate the velocity from the 7mm RM which leads to very favorable comparisons for the 7mm RM. Case in point. A simple look at Hodgdon’s online load data (which I’ve found to be very accurate over the years), shows velocity in the 2900-2950 fps range for a 162 gr 7mm load from the 7mm RM. This is a lighter load than the 168 gr load mentioned in the article and it still fell significantly short of 3000 fps figure in the chart. Only a brand new powder showed data over 3000 fps. It also shows a 208 gr load (closest I could find to a 210 gr) from a 300WM generating 2800-2900 fps. In fact every single powder listed went over 2800 fps. The real world numbers are basically 2900 fps for a 168 gr 7mm load and 2850-2900 fps from a 210 gr 300 WM load. Its basically a wash as far as trajectory when using “real world” velocities. I have no idea where the 3000 fps 168 gr load came from. Nobody makes a factory round with those ballistics. They are all in the 2880-2900 fps which reflects Hogdon’s data. Again, I’ve found Hodgdon’s data to be spot on over years and years of reloading.
So basically the author’s data is inaccurate. He’s overstating the 7mmRM velocity by 100 fps and understating the 300 WM velocity by 50-100 fps. That leads to BS trajectory figures in a comparison of the two cartridges. This is what always seems to happen in comparisons involving the 7mm RM. People always post loads with unrealistic velocities for the 7mm then post loads that are mid-level loads for the 300 WM and even 30-06. I don’t know of any factory load that generates 3000 fps in a 168 gr loading. When most people actually chrono their 7mm Mags they are usually disappointed because most of the numbers on the box are based off of 26″ barrels. Actual real world velocities usually fall way short of what the claimed velocities are.
I don’t want to hear about Joe Blow’s load for the 7mm RM that beats exceeds factory velocity or Hodgdon’s velocities. The 7mm RM is already loaded to very high pressures. Its dangerous to attempt to exceed published velocities.
When you compare apples to apples with a 24″ barrel, the 7mm RM doesn’t really generate very much more muzzle energy than the 30-06 but generates more recoil and uses more powder. Seriously look up the data. The 300 WM is a totally different realm of cartridge than the 7mm as far as energy and hunting large game. It is every bit as flat as the 7mm RM but simply has more energy and carries more energy down range. The 7mm RM is basically a glorified 30-06. A reloader can get the same energy levels from a 30-06 as a 7mm RM loaded to lower pressure.
Jackson says
November 7, 2017 at 11:33 AMThe 7 mag is not loaded as hot as the 300 from the factory. The 7mm is loaded to 60,000psi and the 300 to 64,000psi. And you can easily get 3020fps from a 168gr out of the 7mm. If you want a real apples to apples load to the same chamber pressure and use bullets with similar bc’s.
Chris says
November 10, 2017 at 4:41 AMThe 300 WM is definitely loaded to higher pressures but I still think that the 7mm RM velocities are overstated. Reloaders can usually exceed factory 300 WM by a healthy margin. Its hard to beat 7mm RM factory ballistics by any significant degree. I’m talking actual chrono results. I spend a lot of time at the range and it seems that most factory 7mm RM loads fall short of listed velocity out of a 24″ barrel while most 300 WM tend to meet if not exceed factory published ballistics. If you simply look at Hodgdon’s online loading data you will see it would be very difficult to exceed factory ballistics. There are more powders listed for 300 WM that exceed factory ballistics than for the 7mm RM. There are some reloading manuals that are accurate and some that are not. I’ve found Hodgdon’s data to be remarkably accurate.
CJV says
November 20, 2017 at 6:50 AMRon, perhaps overlooked- 7 REM VS. 300 Win? This is what I’m grappling with comparing the 2 as all round hunting cartridges… Several years back I sat through an Alaskan hunting seminar and will never forget them saying, “bring at least a 30 Cal rifle to AK… That lesser calibers do not dispatch game as quickly”. Jim Zumbo used to hunt with an 06, then a 7 REM Mag. He switched to a 30 Rem SAUM and said at the time it clobbers elk with 150 CL factory loads. This from meeting Zumbo at outdoor shows, reading his articles and in the field once. Jim lost faith in the Big 7. He believed 7mm lost some Whammy on big game out there. Others also say caliber makes a difference in killing ability. In my experience a 338 Win Mag clobbers game, as does a 375… Most of the time. My 338 250 NP dropped a bull elk at 175 yards, lung shot on the spot! Would a 7 Mag or even a 300 do that? I’ve never seen it. I understand the variables, but watching friends shoot elk with 0-6s, the elk bolt! Still I watch videos of hunters shooting elk beyond 1000 yards with a 7 REM, killing them. So I’m more confused than ever on my search for the do-all hunting rifle. I feel silly hunting deer with a 338. So I choose the 300 Win for everything. While I’m not recoil shy, feel the 7 Mag recoil more pleasant. I would like to go back to the Big 7, but not at the expense of watching elk run or require multiple shots. Perhaps modern bullets have equalized things? So when comparing the 7 to the 30, to me velocity, drop, energy between the 2 seems splitting hairs. What I wrestle with is the lesser recoil of the 7 worth trading for the greater frontal area of the 300? I’m thinking the 300 Win is everything the 06 is and more of a good thing and right in-between the 7 Mag and 338. So would I regret switching to the Big 7 hunting deer, elk, moose, black Bear? These days hunting is expensive and limited. What does one really give up shooting a 7 instead of a 300 or 338 when it comes to quickly dispatching big game? Thanks, CJV.
Ron Spomer says
November 20, 2017 at 9:05 PMCJV, you wrestle what all of us wrestle with at one time or another. It’s darn hard to determine which cartridge is best based on limited sample size and inconsistent samples (i.e. different bullets.) We all dote on the cartridge without appreciating or often even recognizing the bullet. I’ll write a blog on this topic in the near future, but for now I’d advise you that there is little difference in terminal effectiveness between these two cartridges when using the same bullets. The frontal area difference is so slight as to be laughable given the impact energies and resulting bullet expansion. To appreciate this, draw a circle that is .284-inch in diameter. Then center it in a circle that is .308-inch. This will show you the narrow band of extra frontal area the .308 bullet offers. Clearly, a .224 bullet compared to a .416 bullet is a big deal, but from .284 to .308? Do ballistic comparisons of .284 and .308 bullets at 7mm Rem Mag. and 300 Win. Mag. velocities and you’ll note the minimal differences. Load similar weight bullets in both (175 gr. in 7 and 180 gr. in 300) and you’ll notice very little difference. If you shoot the 7 better and enjoy it more, use it without any qualms. Just employ a bullet that handles the impact velocities and expands the way you like. (By the way, I’ve floored 6×7 bull elk with 140-grain bullets fried from a 284 Win. and put three 150-grain bullets from a 300 Win Mag in a whitetail without dropping it. Bull moose have fallen to one 120-gr. bullet from a 6.5-06. It’s not horsepower that kills, but bullet placement.)
Tom wolak says
November 20, 2018 at 1:51 AMYour a complete imbecile if you think a 3006 is on a even plain with a 7 mag.a 7 mag will throw a 175 gr bullet at the dsme velocity a 3006 throws a 150 and has much more energy when it impacts the target.
Paul says
December 10, 2017 at 6:20 PMRon,
The sectional density of the 168 grains 7 mm bullet is 0.2976 and that of the 210 grains .30 cal. is 0.3162.
Hardly qualifying for the same form factor. The .30 cal equivalent would be slightly less than 200 grains…A fair comparison would be a Nosler 190 grains accubond long range with a ballistic coefficient of 0.640 versus 0.652 for the 7 mm Nosler equivalent of 168 grains. The 300 Win Mag pushes the 190 grains bullet at well over…3000 fps in a 24 inch barrel.
Your comparison is slanted in favor of the 7 MM. Rem. Mag. I own both and one is hard pressed in a 7mm Rem. Mag. to achieve a muzzle velocity of 3000 fps with a 160 grains bullet let alone 168 grains in a 24 inch barrel.
At equal speed, the .30 caliber bullet will fly every bit as flat as the 7 caliber if not flatter and will hit with far more authority than its 7 mm. counterpart at ALL distances.
Your recoil comparisons are accurate, the reason I mention it is that the article from which I found this link has recoil values that are inaccurate. The 300 RUM in a 10 pounds rifle pushing a 180 grains bullet at 3300 fps will have over 40 lbs of recoil. Around 43 to be exact. A very substantial increase over the 300 Win. Mag. at around 30 lbs of recoil. In general. A difference of over 40 % !!
This of course doesn’t take into account a heavier rifle. At that level another pound of weight in the overall weight of the rifle reduces the recoil by about 4 pounds, give or take. A muzzle brake is a must for prone shooting. I calculate recoil using raw powder weight (not its burning rate), bullet weight, bullet speed, firearm weight. Not taking into account other factors such as stock material, recoil pad, etc…Purely raw recoil which gives a very exact picture.
Aronn Carden says
December 20, 2017 at 6:37 AMHello gentlemen all
I’m an old Australian and that is to say we in Australia have been 20 years behind you lucky beggars in the states. This was very much so in the 50’s when your go to big calibre was a standard 22 Hornet; my God what a thing to behold!! Something to admire and lust after……but I never, at the time, had the money. There we no woderful 30 06’s to be had. No body had or used telescopic sights, ammo was rare and hard to come by. I remember when the 22LR came out and replaced the 22 short; what a sensation that caused. A decade or so later the Japanese scope makers entered the market here in a big way. That was the beginning of an epoch. Large centre fires rifles flooded the place; every man and his dog got one, heck, I bought three, with scopes!!
Well, sixty shooting years have come and gone along with thousands of ducks, crows, galahs, rabbits, roos, emu’s, pigs, foxes , goats, camels and buffalo, a good number of snakes too; no crocs though. When young, if it moved, it collected a bullet; such was farm life and hunting.
Currently, I own a marlin 45 70 carbine (worked), a 7mm rem mag (full custom), a 204 (full custom) a 22 250 (blue printed, SS barrel) and a couple of full competition double barrel 12 gauge shot guns. Now here’s the thing of it. I’ve fired machine guns, sub machine guns, pistols and just about everything you can think of and what I’ve learned is this. There is a thing I call the God Factor that doesn’t appear within any ballistic table, but I do know some of the elements that are in the God Factor; they are:
A. A rifle that absolutely suits you; forget about what your mates think
B. A calibre that you, deep in your heart, aren’t afraid of, no flinch
C. Spend the money, take the pain, don’t be a miser or you will regret it.
D A rifle that you are in love with, flat shooter, fast, no hold over at moderate ranges,
E. A killer out to 1000 yards (depending on game size)
F. Cheap to reload using the best components .
If you do the above, given practise, the shots that you create, make happen, will defy the laws of physics. The sort of shot or shots that live in the eyes of the beholders forever! The God factor e.g. a 22 250 Remington 700 ADL, 3 to 9×40 scope nine o’clock at night, free standing un supported, on the back of a ute, cold bore shot on an Emu (a bloody big fast running prehistoric bird like an ostrich) shot and killed @ measured 1400 yards!! I have no real explanation except good luck. However, that American Remington did just that time and time again; and not just in my hands either. A thousand yard one shot kill on foxes was a regular event (no bs) So, its not always the calibre because on the night in question there were 300wm, 270’s and a 243 plus the 22 250. As regards a 7mm versus a 300 WM and I’ve owned (own) and used both, my current 7mm RM is, in my opinion, superior to the 300 WM when loaded equally. Bye the bye, both my 7mm and 204 cost $15,000 each, they are beautiful and I love them all, they are all proven killers and personally I’d hate to ever be on the receiving end of any of them. Equally, a 300 Wm magnum is a mighty round. However, my next rifle will be the new 300 Norma Magnum because something in the design, spacial relationship, powder column, BC, SD like the 22 250, has The god factor; it just IS…..

Frank says
January 1, 2018 at 5:01 PMGreat article. Like the 300 WM – The 7mm Mag is a very respectable round and great for those who like it. Lots of flavors out there but I’m a big game 30 cal. guy for several reasons and my 300 WM is a sledge hammer on steroids and is ridiculously accurate and I will never look back. It’s just a Remingtom 700 BDL and its never had a factory round thru it since I bought in new. The only down side around here in N.E Ohio is I don’t feel comfortable shooting it around the farm without a deflection ramp behind it to drive the bullets down into the ground because them things don’t stop very easily and I don’t want a 2 or 3 mile ricochet hurting someone. I’m not a competition shooter but I do look forward to trying some of the new higher bc bullets available now days. They equally improve the 7mm as well so I guess the saga continues as to which one is better but my feelings wont ever get hurt if someone prefers the 7mm.
Ron Spomer says
January 1, 2018 at 5:11 PMFrank, good attitude. I wouldn’t look back if I had the satisfaction your enjoy with your 300 Win. Mag. either. My job is to expose guns, ammo and ballistics for what they are and allow my readers to make their own choices. I’m not out to talk anyone into shooting anything specific. Heck, I can’t even decide which rifle/cartridge/bullet I like best. I get to use them all and appreciate their virtues and shortcomings. Not many of the latter. Thanks for joining us!
ac says
January 18, 2018 at 3:39 AM300 win far exceeds the 7mm in muzzle velocity and ft pounds of energy if bullet weights were similar .notice the 300 win bullet was 40+ grains heaver and still ran with the 7mm.. the author is truly a 7mm fan .
Ron Spomer says
January 18, 2018 at 4:32 PMHi AC,
Because I’m always ready to entertain enlightenment and learn new things, I ran some ballistic calculations using your basic information above. Fired from 24″ bls., max velocities from Nosler Reloading Guide 7, 150-gr. Ballistic Tip bullets for each. 3248 fps MV for 7mm; 3420 fps MV for 300 WM. Both zeroed 250 yds. Same atmospheric conditions. 300 started with 382 f-p more energy at muzzle. Because the .308 bullet has a lower B.C., it begins losing energy faster. At 600 yards energy was about equal. At 700 yards the 7mm is ahead. At 1,000 yards the 7 carries 61 f-p more energy. The 7mm deflected less in the wind at all ranges, deflecting 6.5 inches less at 1,000 yards. None of these differences is huge unless you’re a 1,000-yard competition shooter without an anemometer. As for the energy levels making a difference, 50 years of hunting big game around the world suggests to me this isn’t significant either. I’ve applied 160-gr. .284 bullets and 180-gr. .308 bullets to the shoulder/chest of bull elk inside 80 yards. Three shots each. Neither bull went down immediately. Both ran or walked for about six seconds before wobbling and falling over. I once put three 150-grain Ballistic Tips into a fleeing whitetail buck from inside 80 yards. The first two stayed inside the body and failed to knock that deer over even though another hunter had already broken one of its front legs. The deer was bedded when I administered the final shot through the lungs/heart. That shot from about 30 yards didn’t push the buck over, either. You are correct that the 300 WM carries more energy than the 7 RM, at least inside all reasonable hunting ranges. Just remember that winning the velocity race with lighter bullets compromises the wind deflection and downrange energy races. Compare ballistics with same weight bullets or same B.C. bullets and you’ll get different results. Pick your favorite. But, if you decide to embrace the 300 Win. Mag., you’ll be set to hunt anything in the world. Just choose the right bullets. Thanks for reading and offering your observations!
William Pearson, Sr says
March 12, 2018 at 6:09 PMHow does the Rem 700 7mm mag compare with the Rem 700 Win 290 mag? Which rifle is best for 600 yard plus shots? I load all my shells and my favorite is the 140 and the 160 grain bullet weight.
I bought and customized a Mauser 7X57 rifle and made killing shots, on deer, at 300 to 400 yard shots. Like a nut, I let a friend talk me out of this rifle, big mistake. I now have to find a long range rifle that compares with my Mauser.
Any thoughts or suggestions?
Thank you,
WSP
Ron Spomer says
March 12, 2018 at 9:35 PMThe M700 in 7mm Rem. Mag. will outperform the 270 Win. Figure an inch less drop and drift at 300 yards widening to 10 inches and 5 inches respectively at 600 yards. The 7mm will pack roughly 240 f-p more energy at 600 yards. I don’t think any deer or even elk will feel the difference. But if you wish to maximize performance past 600 yards, the 7mm Rem. Mag. is your best option of these two. Good luck!
William Pearson, Sr says

May 18, 2018 at 6:24 AMwonderful posts from all. just buy a 7mm mag. a few years back a marlin. only shot it once. and said ok. only got 24 inch barrel. like longger 27 inch would be nice with open snice they dont put them on no more. scope craze. I worked in oil and lo loging a lot all over the world and slep in the fields and would wake up with the largest anamals next to me drinking or eating .my snoreing brought them in and I would just watch them sometime just two feet from me.not moving. I love it. didt carry any weapon except a long knife for the snakes and fire wood.. When I was in Alaska I got a chance to walk in to walk back in mountain D the largest mountain in north america their I saw the largest bear ever running after a baby elk that bear looked at me but I froze and just use my eyes and he went on with the chase the baby didt stand a chance. I still think about getting him now at the age of 76 you people that post here have answer my question. and I thank you all. my D214 say iam a expert rifleman with a M 1 at 500 yards that was 1959 yesterday I was at the gun range with with my winchester 22 1939 model 67 made for the new ammo and hit a silver dollar at 100 yards so things dont change. 2018 look out bear. Oh both of those rifles use were with out scopes.

June 18, 2018 at 11:56 PMYou know this comparison could go on and on. Both are wonderful rounds, but lately I’m more confused than ever on which one. New bullet technology adds to the pot. So does long range sniping at big game. For general hunting at normal ranges say out to 400 yards, I have always given the 300 Winchester the nod. I find 30 caliber frontal area kills quicker in most situations than 7mm on larger game such as elk/moose. Plus the 300 Win has a bit more whammy than the 308 Win or 30-06. Yet I could say the same for the 338 Winchester, which in my experience kills quicker than the 300 Win. So in a way the 300 Win Mag sits between the 7 Rem Mag and the 338 Win Mag, for a hunter in search of 1 big game rifle compromise. On the other hand having a 7 Mag and a 338 Mag might make more sense than just the 300. With those 2 rifles one would have most North American big game hunting covered with a bit of overlap. For Bison/Moose/Timber Elk/Bigger Bear or Hogs grab the 338. For Deer/Mountain Game/Black Bear/Open Country Elk/Plains Game grab the 7 Mag. With the 2 rifles you would mostly shoot better in wind with 7 Mag and hit harder with 338 Win. I think the 7 Mag is not as versatile as the 300 Win as one gun and the 300 Win a compromise. There is no way I can make a 7 Mag my only rifle and as an example would prefer hunting moose in bear country with a 338. Having just a 300 Win Mag as a compromise bothers me… but it’s a very good compromise for most hunting and why I say the 300 is better than the 7 Mag. While recoil has never bothered me, (I shot 416s) the lesser recoil of the 7 Mag is inviting and a viable reason to choose it. To make this choice even more difficult I’ll throw in the new high BC bullets but also new frangible hunting bullets made by DRT. For some reason many gun rags seem to avoid writing about/testing them. Perhaps the new technology/idea is too scary or threatens conventional $ wisdom? But online DRT recommends the 243 Win with their DRT bullet for elk, and show a video with a quick 243 elk kill as if struck by lightning! Same with a 270 Win DRT bullet on a bison. DRT says their bullet in 30-06 can handle any NA Game. They shoot multiple Aoudad online with their DRT bullet in 223… one shot quick kills! I have no idea if their DRT bullet is that good, but will hunt with them and find out. If my 300 Winchester using 150 DRT grain kills better than my 338 has with regular bullets, that could make the 300 Winchester the ultimate 1 gun choice! DRT does not make 7mm bullets yet. Everyone laughed when the Berger VLD came out. Now their laughing at DRT. So again if the DRT 150 or 175grain 300 Win can quickly dispatch any game, it’s the better choice than the 7 Rem Mag. For that matter a 243 shooting DRT bullets might be all one needs for everything? The owner of DRT told me he shot a Bull elk at 400 yards with a 243 Win/DRT bullet and it dropped! New bullet technologies may change everything and could even obsolete rounds like the 7 Rem Mag and 300 Win Mag?
Ron Spomer says
June 20, 2018 at 8:13 PMChris, the DRT bullets are certainly worth investigating. I shot a few in 243 Win. that demolished at gallon plastic jug of water and went out the backside to blow a wide hole through a sheet of corrugated cardboard, suggesting internal organ damage to a deer or elk would have been devastating. Unfortunately, accuracy was quite poor in that particular rifle, which is typically sub-MOA. I’d like to try the DRT on game, but there are only so many tags in a season… Let us know how DRTs perform for you.

July 4, 2018 at 5:00 AMI own the 270 wby mag,7 rem mag and 7 wby mag, 300 win mag and of them all I think the 270 wby mag is the best all around hunting rifle of them all.All of these magnums are great but the 270 does what the others do with less recoil.
john clayton says
September 18, 2018 at 11:58 PMI guided and outfitted in the Gros Ventre area for years. The 7mm mag couldn’t compete with the 300. With a good hit and a bullet of at least 150 grain, the 7mm would do the job most of the time on elk but the 300 never failed with even a mediocre hit. We were constantly tracking 7mm hits but only one 300 hit required tracking in 17 years. Then you would even get dudes that would show up with a 7mag and extremely lights bullets. I wouldn’t even pack them in till we went to Jackson and got the heaviest round available and re-sited in.

November 11, 2018 at 1:02 AMif a 7mm rem mag and a decent bullet fails to kill your elk,,,, then i doubt much else would work either,i have killed a lot of bulls with the 25-06 and good bullets,,,,,they die right away,,, the 270 ,30-06 and 308 also have all it takes to do the job,,,,,but the 7mm rem mag is a very good cartridge ,,hard to beat,
David W. Grohman says
November 8, 2018 at 3:28 AMWhen I turned 16 years old on November 6, 1966, my father who was a WWII Army Veteran Expert Rifleman, took me to a local Sears & Robuck store to purchase for me, my first rifle. When we stepped up to the small sporting counter, there was a man working who looked like the guy who invented the
AR-15. Glasses and all. Back then, I had no idea who that was. As I stood there looking at all of the fine
wood stocked rifles that were lined in a row behind him, in an open display case, my eyes found what I was looking for. I had done some research on my “1st Rifle” in the Gun Digest & Shooters Bible, when time permitted me to do so, for the previous 2 years. I had read numerous articles about Remington’s NEW 7mm Magnum Rifle & the cartridges performance in ballistics and short hunting history at the time. My father was keen on the 30-06 cartridge performance, after carrying an M1 Garand around the E.T.O. for 19 months, in Great Brittan, France, Germany, Belgium, Holland with the 95th Infantry Division & the 3rd Army. He was set on buying a bolt action with the 30-06 caliber. The man behind the counter smiled at me and said, “Son what are you going to hunt?” I replied, “White Tail Deer, Mule Deer, Antelope, and maybe Elk & Moose!” He then turned to the rifle display and picked out and gently presented a brand new Remington 700 ADL Bolt action. My father took it into his arms and inspected it for balance and weight. Then he shouldered the rifle and said “I like the feel and fit!” It had a shiny Walnut wood Monte Carlo stock and a Remington recoil pad on it. “What do you think son?” I asked to hold it and feel the rifles balance in my arms. I noticed it was stamped 30-06 on the barrel. “Dad, I was thinking on getting a 7mm Magnum.” My Father said fairly loud, “Why do you want a Jap bullet to hunt with?” The man behind the counter laughed at my reaction to my Father’s question and turned to the area where the ammunition was stored. He took a box of shells and opened it and withdrew one casing with a 180 grain bullet and sat it upright on the counter, directly in front of my father. It was a 30-06 Remington Core Lockt shell. My dad picked it up and smiled and said, “Now that’s what I’m in favor of hunting with!” Then he slowly opened another box of Remington Core Lockt shells and sat it upright next to the 30-06 shell that my Dad had returned to the counter. He then said to my father with a smile, “This is a fairly new caliber that Remington has come out with a few years ago, it’s not a Japanese Caliber!” My father said, “HOLY COW!” “That’s almost as big as a 50 Caliber Machine Gun Shell!” “My son doesn’t need something that big to go hunting with!” The man laughed at my Dad’s response and then looked at me and asked me, “Son is this too big for you?” “NO WAY!” I quickly responded. He then turned to the rifle display and retrieved another identical looking rifle and presented it to me to examine. It was another Remington ADL bolt action. Only this rifle was a 7mm Magnum and it had a deep blue Stainless Steel 24″ Barrel. The smile on my face convinced both my Father and the sales rep that I was holding my Birthday present in my arms. Boy did it feel good! “How do you like it?” “It’s the one for me Dad!” “How much?” “It’s $99.00 including sales tax.” “Okay!” “We’ll take it!” “Fine choice sir!” “And your son knows what’s new on the Rifle Caliber Market these days!” I smiled from ear to ear as I watched him put my new hunting rifle into the new original factory box. “THANKS DAD!” I then proceeded to look at the rifle scopes on display. I asked him to see the Leupold Vari X II Gold Ring in 3 to 9 power with a 50mm objective. As I inspected the scope in my hands and looked through the eye piece I liked what I saw and imagined that scope mounted on my new Remington ADL Bolt Action 7mm Magnum Rifle. “How much?” “$103.00 with sales tax,” he said to me. I said, “No problem I got it with me!” Looking at my Father I said, “Dad I’ve been saving up for this scope for over 2 years since I started reading about the Remington 7mm Magnum Rifle.” “The experts say the combo is a perfect match!” My father replied to the sale rep, “You heard my son, wrap it up!” “He’s buying the scope!” The sales rep was laughing and was very pleased in my choice and knowledge of my first hunting rifle and scope. After many successful hunts in Michigan for White Tail Deer and several hunts out west in Colorado and Wyoming for Mule Deer & Antelope, that same rifle that my Father purchased for me 52 years ago, has the #1 slot in my gun safe. And the same scope is still mounted on top of it! I use Remington 175 Grain Core Lokt Bullets for Deer & 125 Grain for Antelope. It still shoots like a “NEW ROPE!” Thanks Dad!

December 30, 2018 at 4:12 AMLoved the story ! It fits perfectly, because all choices were good ones…but you got what you wanted not what dad thought you might need. (with respect here)

December 4, 2018 at 7:03 PMThanks Ron for the comparison info.
I’ve been looking at the the 7mm Rem. Mag. in a 700 26″ heavy barrel.
I already have almost all of the
30 cal. combinations so I was wanting something else to play with.
Donnie M. says
January 19, 2019 at 5:52 PMWould love to see you compare the 6.5 PRC to the 7 rem mag and the 270 win. That comparison would be interesting especially for a light North American big game rifle. Looking forward to this comparison.
Ron Spomer says
January 26, 2019 at 4:01 PMGood idea Donnie. I’ll try to get to it. I can tell you without looking too deeply into it that they’ll all be quite close with the 7mm winning by a hair. But the data could prove me wrong.

Another great article! My first big game bolt action rifle was a Savage model 111 chambered in 7mm rem. mag. I bought that rifle at Gart Sports for $200.00 back in 1997. I choose that caliber because of it’s reputation for taking down any of north America’s big game animals with relative ease. It’s also in my opinion, the best cheap long range cartridge you can own. Ammo can be found almost anywhere, and you’d be hard pressed to beat this cartridge by a large margin with any other magnum cartridge. Nowadays hornady precision ammo loaded with 162 grain eld-x bulets sells for $42.99 per box. These loads will rival any long range hunting handloads! I have a Weatherby Mark V Accumark chambered in 30-378 Weatherby Mag. I skipped over all other 30 caliber magnums and picked it, simply because it’s the king of 30 caliber cartridges. However because it’s expensive to shoot I recently needed a rifle that could bridge the gap between my 25 caliber rifles and my 30-378 weatherby mag. Long story short I bought a Browning Xbolt composite long range chambered in 7mm rem. mag and haven’t looked back. I feel that I don’t need the Weatherby any more since the 7mm rem. mag can do almost as well at long range! I would pick the 7mm rem mag over a 300 win mag 10 out of 10 times. If I needed a medium 30 caliber rifle, I’d buy a 30/06!

Great article! I have found that many 300 Win Mag “True Believers” will often talk about shooting heavy 200-220 grain bullets, but they routinely shoot 150-165 grain loads for most things. It seems that the loads from 180 on up really kick more than most people can shoot well.
So I pose the question; if you’re going to shoot bullets lighter than 180 grains, wouldn’t you be better served by long, high-SD, 160-175 grain bullets?
There is a load in the Nosler reloading guide that reaches 2970fps with the 175grain partition. It shoots very accurately in my Browning A-bolt, and flattens what it hits.
Ron Spomer says
April 3, 2019 at 8:11 AMAlaska, you can certainly do well with high B.C. bullets of 175-gr. in any 300, but you won’t get the highest B.C. values until 210- to 230 grains, and that means more recoil. As to what each shooter can handle, that’s quite variable. A big part of the reason these little 6.5s are becoming so popular is because of those light recoiling 140 to 147-gr. bullets with the same B.C.s as 200 and heavier .308 bullets.

April 6, 2019 at 7:22 AMHave been hunting the US and Mex for 50 years. Unofficially, have the no. 1 Del Carmine
Whitetail head taken in 1974 when I went thru the Mex Customs Station across from Big Bend
National Park with a 1965 Win. Model 70 in 264 mag. Showed it to them , let them have
fun with the scope. No problem, because like somebody said, the past is another country.
Rode a bus south east to a lumber road heading up into forest heavy dark and heavy with old growth timber. You cannot believe the feeling that takes you when you find your first jaguar print in the dirt. Now you are alive like no other time. Went up the moutain, took the deer, returned with the quarters. Helped push the bush on the then two track roads back to customs and the Rio Grand. There was no US Customs. Shared the meat, brought home a quarter and the antlers.
Still have the skull cap and antlers in my garage. They don’t get that big today and the once
forest has been converted to grazing land. Cull hunted US Federal lands and removed
over three hundred animals averaging 400 lbs. From this, you learn things. You learn that
Spomer knows of what he speaks, dont know how he always remains polite with his authentic reality based experiences, dealing with guys who read ballistics charts. I do not however like
his light rifles. A Weatherby featherweight in 280 Rem beat the crap out of me. Never again, but
God bless those who can use them.
I have found the 7 mag in a rifle of proper weight to be the best combination of reliable
effectiveness at ranges over 300 yards, tho the 30-06 never failed at under 300. My Ruger
Express gets 3150 fps with 160 grain Nosler Partitions and same with Hornady SST’s. I get
three reloads before the primer pockets begin to get sloppy. Rem 7 mags are factory loaded to lower
pressures than 30’s because by the end of the 60’s the big 7 had a reputation as a barrel burner,
because shooters hot shot the throats to erosion, causing more friction on bullet jackets, causing higher pressures than in new barrels, in turn causing ammo makers to load to lower pressures.
The only thing more deadly than a big 7 , in my experience is a 35 Whelan used at 250 yards
or less, but that is another story. Accuracy depends on rifle, load, and marksman so no need
to compare accuracy with 300 mag. There, too many factors affecting. My Ruger Express with 24 inch barrel places 4 rounds in two inches, at 300 yards, using a bipod attached at the barrel, not the forestock. The point of impact using sand bags, and accuracy, is equal to bipod use. I use a Winchester ball powder not available for nearly ten years, but I have carefully horded a few pounds.
Old man Ruger said they closed the assembly line to regular work when they did those barrels, and that each of them required a complete 8 hour shift to finish. I believe it.
