Rimfire ammunition has its primer compound built into the rim of the case rather than a separate primer in the center. The firing pin strikes the rim to ignite the powder.
.22 LR is by far the most popular rimfire caliber thanks to low cost, wide firearm availability, and minimal recoil. It works well for training, plinking, and small game hunting.
No, rimfire cases are not designed to be reloaded because the primer compound is built into the rim. Once fired, rimfire cases are typically discarded.
.22 LR is a low-velocity rimfire cartridge ideal for plinking and small game, while .22 Magnum produces higher velocity and energy for greater range and stopping power. The two are not interchangeable in most firearms.
Modern rimfire ammunition is generally reliable, though it has a slightly higher failure rate than centerfire due to the priming process. Quality ammo and a clean firearm help reduce misfires.
Rimfire calibers are typically not recommended as a primary defensive choice due to lower energy and reliability concerns. Centerfire calibers are generally preferred for defensive use.
Keep rimfire ammo in a cool, dry place away from temperature extremes and direct sunlight. Sealed containers help protect rounds from humidity and corrosion over time.
.22 LR demand often outpaces supply during periods of high firearm activity or supply chain disruption. Buying in bulk when available helps maintain a steady supply for regular practice.
