Jbm balistics.

The ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Bullet Length The length of …A ballistic coefficient is a comparative value for a given bullet, showing its relative resistance to drag versus a model projectile that has an empirically established set of drag characteristics. This article originally appeared on The Firearm Blog. When a bullet flies through the air, forces called "drag" are exerted upon it.I have a question concerning data input on the JBM site. In their section for trajectory cards they ask to input the altitude. I'm assuming they are asking for the density altitude, but they don't really say. Anyone know for sure? Are they asking for the density altitude or just regular...Terminal ballistics: the study of the interaction of a projectile with its target, whether that be flesh (for a hunting bullet), steel (for an anti-tank round), or even furnace slag (for an industrial slag disruptor)." ...

JBM Small Arms BallisticsJBM ballistics doesn't have the M72 bullet in their inventory, so I used the 175 SMK as a proxy. To get 2550 fps at 78 yards you need a muzzle velocity (measured 10 feet from muzzle) of 2690 fps, which is 2696 at the muzzle. Seems like the 2640 fps listed in the technical data will get you to the 2550 +/- 30 if you go on the minus side.

Suggestion: Zero in your outfit at 50 yds, then, on a clean target, shoot a 5-shot group at the same distance. Circle this group with a pen or whatever and write "50" next to it. Next, take the same target and put it up at 100 yds, and shoot another 5-shot group. Circle this group, and label it also.
