A bullet is stable if: Sg >. 1 Sd (2-Sd) If you plot that on a graph, you wind up with the following chart: As you can see, there are two regions divided by the line represented by the above equation. If a bullet is inside the stable region, all is good. If it leaves the stable region, it will tumble.

You can, but not very accurately. If you look at the bullet drop for two bullets, one with a BC of 0.5 and the other with a BC of 0.55, you'll find that the bullet drops at 300 yards with a muzzle velocity of 3000 f/s and a 100 yard zero, are -10.9" and -10.7" respectively. So if you can shoot groups less than 0.2" at 300 yards, have at it.Ballistic is the definitive ballistics trajectory calculator for iOS devices, intended for serious shooters who want a serious (and seriously accurate application).
