A rimfire firing pin produces a notch at the edge of the case; a centerfire pin produces a depression in the center of the primer. It is named rimfire ammunition as the firing pin strikes and crushes the base's rim to ignite the primer. The rim of such a cartridge is essentially an expanded and flattened end section of the case, and the priming ...

The firearm firing pin crushes this explosive between the cup and an anvil to produce hot gas and a shower of incandescent particles to ignite the powder charge. [2]
This can be a problem for magnum revolvers or rifles which simultaneously chamber more than one round of ammunition, as the recoil from the firing successive rounds can loosen the bullets in the remaining cartridges, and cause their bullet seating depth to change, which can have a serious effect on accuracy, or could, in the case of a revolver ...
The pin-fire (or pinfire) is an obsolete type of metallic cartridge used in firearms, where the priming compound is ignited by striking a small pin that protrudes radially from above the base of the cartridge.
