Bullet Ballistic Coefficient Calculator

Ballistic Coefficient(BC) is a measure of a bullet's ability to resist the deccelerating forces produced by air drag. A bullet with good aerodynamic qualities (high BC) will maintain its speed and kinetic energy to a longer distance than a less well designed bullet (low BC). X-sectional area, shape and mass affect BC as well as temperature, humidity and barometric pressure.

The calculation method used here is derived from US military ballistic equations that rely on empirical velocity measurements rather than theoretical considerations. Fidelity with ammunition manufacturer's published ballistic data is very good.
