RimfireHülse

RimfireHülse refers to the cartridge case used in rimfire ammunition. Rimfire ammunition is a type of self-contained explosive ammunition where the primer is a combustible or non-combustible compound that is ignited by striking the rim of the cartridge case. This contrasts with centerfire ammunition, where the primer is located in the center of the cartridge base.

The rimfireHülse is characterized by a hollow rim at its base. This rim is specifically designed to be struck by the firing pin of the firearm. The firing pin indents the rim, crushing the priming compound within it and causing ignition. This ignition then sets off the main propellant charge within the cartridge case, launching the projectile.

Rimfire cartridges are typically of smaller caliber and are often used for training, plinking, and small game hunting. Common rimfire calibers include .22 Long Rifle, .22 WMR (Winchester Magnum Rimfire), and .17 HMR (Hornady Magnum Rimfire). The simple and cost-effective design of rimfire ammunition, including the rimfireHülse, contributes to its popularity and widespread use. Due to the construction of the rimfireHülse, rimfire cartridges are generally not reloadable in the same way as centerfire cartridges.
