The Pin-fire Cartridge
One of the first kinds of metallic cartridges made was known as the pinfire cartridge, and since it was formed of a metal shell it was called a metallic cartridge, a name that is used to this day.
In the closed end of this cartridge a firing-pin was fixed and the fulminating powder covered this pin on the inside of the shell; then the powder was put in and on top of this the bullet was set and held in place by the pressure of the open rim end of the cartridge. When the hammer of the gun struck the pin of the cartridge it exploded the latter and sent the bullet whizzing on its way.
