I'm curious as to what the "ballistic coefficient" of ammunition is actually measuring. Can anyone give me a (hopefully) easy to understand, yet detailed explanation of it?

Ballistic Coefficient (BC) is basically a measure of how streamlined a bullet is; that is, how well it cuts through the air. Mathematically, it is the ratio of a bullet's sectional density to its coefficient of form. Ballistic Coefficient is essentially a measure of air drag. The higher the number the less drag, and the more efficiently the bullet cuts through the air. So for purposes of flying through the air efficiently, the bigger the BC number the better.

the article goes on... good read

there are also programs available that will calculate ballistic coefficients for you...
