Rimfire ammunition is a type of cartridge that uses a primer located in the rim of the cartridge case to ignite the propellant. This design makes rimfire cartridges simpler and less expensive to manufacture compared to centerfire ammunition. The most common caliber for rimfire ammunition is the 22 Long Rifle, widely used for target shooting, small game hunting, and training. Rimfire cartridges are typically less powerful than centerfire cartridges, making them suitable for recreational shooting and beginners. They are often found in rifles and handguns designed specifically for rimfire use. Due to their lower recoil and noise, they are popular for indoor shooting ranges and youth training programs.
