Mathematically, it is the ratio of a bullet's sectional density to its coefficient of form. Technically, its the ratio of the weight to the surface area, but its easier to think in terms of diameter as thats how bullets are measured. His latest projects include an online course to help people get an FFL (. The extent of how much a BC will change depends on each unique bullet shape. Then, for other bullet types, we can create a fudge factor that adjusts the standard bullet trajectory model. Thats basically what the ballistic coefficient does. .243" 100 grain Round Nose (BC .216): -1.5" @ muzzle, +4.8" @ 100 yards, +6" @ 200 yards, 0 at 300 yards, -15.9" @ 400 yards, -46" @ 500 yards. It get that G1 is an average under 500 yds and G7 is an average over 500 yds up to sonic velocity when everything falls apart. Also notice the big difference in BC between the round nose bullet (.216) and the spire point bullet (.357). How much a bullet slows down depends on the density (thickness) of the air and the efficiency of the bullet. In addition to the standard G series bullet profiles, a Custom Drag Curve (CDC) can be used for a specific bullet which is the actual drag characteristics for that bullet. Getting consistent hits at extreme distances requires specialized rifles and optics. If you look at the G1 bullet image, youll see that it resembles a common projectile shape from the 1800s era, give or take.
