What defines centerfire ammunition?

Centerfire ammunition is defined by the placement of its primer, which is located in the center of the base of the cartridge casing. This central placement allows for more reliable ignition of the propellant within the cartridge, contributing to consistent performance in shooting activities. Because centerfire cartridges utilize this design, they are typically found in a wide range of firearms, including rifles and handguns, which are used for various hunting and shooting applications.

The characteristic of centerfire ammo being reloadable is significant; many centerfire cartridges can be reloaded, making them cost-effective and environmentally friendly for shooters who practice frequently. In contrast, rimfire ammunition, which has the primer located in the rim of the casing, is generally not reloadable. This difference highlights the advantages of centerfire ammunition for both experienced and novice shooters.
