{wiki=Pinfire_cartridge}
A pinfire cartridge is a type of ammunition that was prevalent in the 19th century. It was one of the earliest forms of self-contained cartridges, which combine the bullet, powder, and primer in a single unit. The pinfire cartridge features a pyrotechnic primer that is activated by a pin on the firearm's hammer striking the exposed pin on the cartridge's side. When struck, the pin ignites the primer, which in turn ignites the gunpowder and fires the bullet.
