When the pressure builds up high enough to overcome the crimp friction between the projectile and the case, the projectile separates from the case and gets propelled down the gun barrel, imparting high kinetic energy from the propellant gases and accelerating the projectile to its muzzle velocity. The projectile motion driven by the propellant inside the gun is known as the internal ballistics.

After a week of playing with my write-up, talking with Rich Rains and others, and wondering what happened in 1928, it struck me – what if they started the half-year system in 1928, continuing the alphabet but now using two letters to a year and deleting the same letters the gun barrel guys did.

These guns used a spring-loaded hammer to strike a percussion cap placed over a conical "nipple", which served as both an "anvil" against the hammer strike and a transfer port for the sparks created by crushing the cap, and was easier and quicker to load, more resilient to weather conditions, and more reliable than the preceding flintlocks.[11]

Non-lethal projectiles with very limited penetrative and stopping powers are sometimes used in riot control or training situations, where killing or even wounding a target at all would be undesirable. Such projectiles are usually made from softer and lower-density materials, such as plastic or rubber.

AP bullets are sometimes Shop Now less effective on unarmored targets than FMJ bullets are. This has to do with the reduced tendency of AP projectiles to yaw (turn sideways after impact).
