To determine if your rifle is rimfire or centerfire, examine the cartridge it uses. Rimfire cartridges have the primer located in the rim of the cartridge case, while centerfire cartridges have the primer located in the center of the base. Additionally, rimfire rifles typically use smaller calibers, such as .22 LR, whereas centerfire rifles encompass a broader range of calibers and are generally used for higher-powered ammunition. If you're unsure, refer to the manufacturer’s specifications or markings on the rifle.
