Two of the most important parameters in ballistics are the initial speed of launch (e.g., MV = gun muzzle velocity) and the "ballistic coefficient" (BC) of the projectile (i.e., the dimensionless ratio of the weight/drag of the projectile to the weight/drag of a standard reference projectile defined to represent BC = 1.0). A BC-measurement scheme that combines a PC with inexpensive acoustic sensors (electret microphone cartridges) to measure projectile time-of-flight (i.e., time between the sounds of launch and target impact) over two different target ranges.
