Muzzle velocity

Muzzle velocity is the speed that a bullet travels as soon as it is fired. Bullets with higher muzzle velocities tend to have higher effective ranges.

The shells are fired through a Velocity Screen, which has a grid of copper wire. When the shell is fired through the wire, the circuit is broken, by which the speed of the shell can be checked.
