Table Range
True to your rifle (optional: match what you saw at the range)

Shoot at one to four known distances and note the elevation that actually put your group on the center of the target at each. The calculator adjusts the BC (and the muzzle velocity, if it isn't chronographed) to fit what you saw. Distances of 300 yds or more, and especially 600–1,000 yds, work best. Use the zero, sight height, shooting angle and weather from the day you shot.
