Fired rimfire and centerfire casings, showing the impression left by the firing pin. Note the rectangular impression left by the firing pin on the rimfire cartridge.

Comparison of centerfire and rimfire ignition Fired rimfire (left) and centerfire cartridges. 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. Rimfire ammunition is so named because the firing pin strikes and crushes the base's rim to ignite the primer. The rim of ...
A small number of rimfire and centerfire firearms of older design should not be test-fired with the chamber empty, as this can lead to weakening or breakage of the firing pin and increased wear to other components in those firearms. In the instance of a rimfire weapon of primitive design, dry firing can also cause deformation of the chamber edge.
Rimfire: A type of firearm cartridge that used a firing pin to strike the base's rim, instead of striking the primer cap at the center of the base of the cartridge to ignite it (as in a centerfire cartridge).
When the rim is then crushed by the hammer or firing pin, the primer detonates and ignites the powder charge. Rimfire cartridges are usually single-use and normally cannot be reloaded. Also, since the rim must be thin enough to be easily crushed, the peak pressure possible in the case is limited by the strength of this thin rim.
