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.
These are offered in supersonic and subsonic types, as well as target shooting, plinking, and hunting versions. These cartridges are usually coated with hard wax for fouling control.
nove×19mm Parabellum: Invented for the German military at the turn of the 20th century, the wide distribution of the 9×19mm Parabellum round made it the logical choice for the NATO standard pistol and Submachine gun round.
Modern primers are basically improved percussion caps with shock-sensitive chemicals (e.g. lead styphnate) enclosed in a small button-shaped capsule. In the early paper cartridges, invented not long after the percussion cap, the primer was located deep inside the cartridge just behind the bullet, requiring a very thin and elongated firing pin to pierce the paper casing. Such guns were known as needle guns, the most famous of which was decisive in the Prussian victory over the Austrians at Königgrätz in 1866.

Clue number 2 – At some time in the past I had been given the interpretations of two codes. D19WFJ was stamped on the bottom of a plain, otherwise unmarked UMC style box of experimental .30 S&W Automatic cartridges that had come from old-time cartridge dealer John Hintlian. He was tireless in running down leads and making deals with everyone in the ammo business. His files and collections filled rooms at the motel he owned on the Berlin Turnpike. He must have come upon the code interpretations or knew the right someone at Remington because beneath the stamped code, in John’s distinctive handwriting, was the interpretation AUG 19, 1912.
Centerfire primers are a separately manufactured component, seated into a central recess at the case base known as the primer pocket, and have two types: Berdan and Boxer. Berdan primers, patent by American inventor Hiram Berdan in 1866, are a simple capsule, and the corresponding case has two small flash holes with a bulged bar in between, which serves as the "anvil" for the primer.
