What is Rimfire Ammo?
Rimfire ammunition is one of the two major cartridge ignition technologies in widespread use. When the trigger of a gun firing rimfire ammo is pulled, the weapon's firing pin strikes the edge, or rim, of the cartridge's base and ignites the primer. This, in turn, ignites the propellant in the case, firing the bullet out of the gun. While large caliber rimfire cartridges were once common, most rimfire ammunition used today is of relatively low caliber; the most popular of these is the .22 Long Rifle, which is primarily used for hunting and target shooting. Firearms chambered for rimfire cartridges are diverse and range from single-shot precision target guns to AR-15 derivatives.Due to the fact that the case must be somewhat weak for the firing pin to ignite the primer, rimfire ammo is not reloadable. However, as thin rimfire cases do not require as much material as centerfire ones do, rimfire cartridges are relatively inexpensive to manufacture and are generally more cost-effective to shoot than centerfire ones. One notable exception is high grade competition ammo, which is made to extremely tight tolerances and with stringent quality control.
