A rimfire cartridge is a type of ammunition characterized by its primer being located in the rim of the cartridge case. This design allows the firing pin of a firearm to strike the rim, igniting the primer and firing the bullet. Rimfire cartridges are typically smaller and less powerful than centerfire cartridges, making them popular for target shooting and small game hunting. The most common rimfire cartridge is the .22 Long Rifle, known for its versatility and low recoil. Rimfire ammunition is generally less expensive and easier to produce, which contributes to its widespread use among recreational shooters and beginners.
