Jbm ballistic.

The BC, or ballistic coefficient is defined as: BC = w / [i d 2] here the diameter is specified in inches and the weight in pounds and the form factor is found using: i = CD / CD G. The sectional density is defined as: SD = w / d 2. making the ballistic coefficient BC = SD / iFeatures: World renowned JBM ballistics engine for the most precise, accurate calculations in the industry.

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.
