A centerfire cartridge is a type of ammunition that features a primer located in the center of the cartridge case's base. This design allows for reliable ignition when struck by the firing pin of a firearm. Centerfire cartridges are commonly used in rifles and handguns, making them popular for both hunting and target shooting. The construction of a centerfire cartridge typically includes a bullet, gunpowder, and a casing that holds all components together. Unlike rimfire cartridges, which have the primer in the rim, centerfire cartridges can be reloaded, making them more economical for frequent shooters.
