What is rimfire ammo?

Rimfire ammunition is a type of cartridge typically used in small-caliber firearms, such as .22 rifles and handguns. It gets its name from the fact that the firing pin strikes the rim of the cartridge to ignite the primer.

Rimfire cartridges are known for their relatively low cost and versatility, making them popular among recreational shooters, hunters, and competitive shooters. They come in a variety of calibers, ranging from .17 to .22, and are widely available at most gun stores and sporting goods retailers.

One key characteristic of rimfire ammunition is that the cartridge casing is made of a soft, malleable material, such as brass or copper. This means that rimfire cartridges cannot be reloaded like centerfire cartridges, which use a harder, reloadable casing.

Overall, rimfire ammunition is a popular choice for plinking, target shooting, pest control, and small-game hunting due to its affordability, accessibility, and low recoil.
