Rimfire Ammunition FAQ

Q: What is rimfire ammo and how does it differ from centerfire? A: When looking at what is rimfire ammo, the defining feature is how the cartridge is ignited. In a rimfire round, the volatile priming compound is spun directly inside the hollow, flattened rim at the base of the brass case. The firearm’s firing pin strikes the outer edge of the rim to ignite the powder. By contrast, centerfire ammunition uses a separate, self-contained primer cup pressed into the exact center of the cartridge base.

Q: Can you reload rimfire ammunition cases? A: For the average handloader, no. Unlike centerfire brass, which allows you to pop out the spent center primer and press a new one in, a rimfire case has its rim structurally crushed by the firing pin upon ignition. Because the priming compound must be chemically spun inside the rim during factory production, rimfire brass is considered single-use only.

Q: Is vintage ammunition like 32 rimfire ammo or 44 rimfire ammo still available? A: Historic cartridges like 32 rimfire ammo and 44 rimfire ammo are obsolete and no longer produced by major modern factories. While small batch runs are occasionally made by specialty boutique manufacturers, these rounds are highly sought after by collectors. If you are shooting modern firearms, sticking to standard production calibers like .22 LR, .22 WMR, and .17 HMR ensures consistent availability and performance.
