Ammunition is referred to as rimfire because of the mechanical action involved during shooting. These types of ammunition rely on the firing pin of the firearm to crush the rim of the base, igniting the primer. This is quite different than conventional ammunition which typically strikes the primer at the cartridge's base instead of the rim.
