Ballistic coefficient - Wikipedia

In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass. BC can be expressed with the units kilograms per square meter (kg/m 2) or pounds (mass) per …

What Is Ballistic Coefficient? - The Lodge at …

Defining Ballistic Coefficient Simply put, ballistic coefficient is a numerical measurement of a bullet's ability to cut through the air. If a bullet has a high BC, then it is better able to slice through the atmosphere without being slowed by air particles. Bullets with higher ballistic coefficients resist drag better than bullet with low BC.

what does "ballistic co-efficient" mean? | Shotgun Forum

Ballistic coefficient is a measure of how efficiently a bullet travels through air and hence retains it's velocity. Roundballs have a very low ballistic coefficient. They do not travel through the air efficiently so they lose velocity rapidly due to high drag, resulting in "rainbow" trajectories and severe wind drift.
