B.C. literally means "before Christ" and is the dating mechanism used for early human history. However, due to a miscalculation, the calendar start time does not correspond to the exact year of Jesus' birth, which actually occurred a few years earlier.
Firearms Term B.C.
- In firearms terminology, B.C. refers to ballistic coefficient. According to gun writer Matthew Boyd, ballistic coefficient is "the ratio of a bullet's sectional density to its coefficient of form. BC represents how efficiently the bullet flies through the air; the higher the BC number the more aerodynamic the bullet."[1]
