| Someone please enlighten me as to the meaning of ballistic coefficient. I think it has something to do with a bullets ability to retain velocity and keep its ballitic course. I heard the term used in reference to bullets decelerating from supersonic to subsonic velocities at specific ranges, which causes the bullet to destabilize. A more scientific explaination would be greatly appreciated. Here's a good opportunity to show off your wits gentlemen, let my enlightenment begin. |

The ballistic coefficient is a measurement of how well a projectile flys in the air. It relates the drag deceleration of a projectile to the drag deceleration of a standard bullet. The higher the ballistic coefficient, the better the bullet performs in air. (1) C = SD/i = w/id2 C = ballistic coefficient w = weight of bullet, lbs. i = form factor SD = secetional density d = diameter of the bullet, in. |
