There is also a group size calculator, also $10.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.

The JBM Ballistics engine utilizes Litz-derived Ballistic Coefficient (BC) values, based on field testing by Bryan Litz, a champion shooter, aerospace engineer, ballistician, and author of the highly regarded Applied Ballistics for Long Range Shooting. The BC is a measure of the capability of a projectile to overcome air resistance in flight.

Applied Ballistics App.The formulas for the drag function as a function of the drag coefficient can be found here . For any bullet, the drag force must be the same no matter what drag function is chosen since the drag force is physical and depends on the shape of the bullet. This means that the following equation must be true. G (M)/C = G (M)/C.Trajectory μCard - Constant Drop. Calculate a trajectory card from bullet, velocity, firearm and atmospheric parameters. Density is calculated using input density altitudes. Muzzle velocity is found by using linear interpolation between two velocities measured as a fuction of temperature. Explanation of terms.the ballistics program said it would be about a 12" drop or 4MOA, but it was more like 16-17" drop. this would mean the muzzle vel. was around 2500fps but it was advertised on the site as 2840fps. by the way, the site is awesome, i have been reading for a couple months now and have learned a lot.

Trajectory. Regardless of its bullet weight, the 9mm provides just the kind of flat trajectory that is most conducive to accurate shooting. Bullet drop tends to range from 10 to 12" at 100 yards. That's likely more distance than you'll need for self-defense. 9mm loads frequently deliver a muzzle energy greater than 300 ft lbs.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.A modified (modified by R. L. McCoy) version of M. A.
