What is BC?

Posted October 15, 2012

BC stands for “Ballistic Coefficient”. In words, BC is a measure of how well a bullet retains velocity; the higher the BC, the more velocity is retained, and vise-versa. Heavy bullets with streamlined profiles will have higher BC’s than shorter bullets with blunter profiles. BC is the fundamental measure of external ballistic efficiency and performance. The higher the BC, the better the bullet retains velocity/energy and resists wind deflection and drop.

BC is more important for long range shooting than short range. The BC’s of Berger bullets are based on carefully controlled test firing and are accurate to within +/- 1%*. All BC’s reported for Berger bullets are corrected to the ICAO Atmosphere.
*For some flat based bullets which are typically used at short range, BC’s are based on calculated rather than fired BC’s.
