centralfire

Centralfire refers to a type of metallic cartridge primer used in ammunition. It is characterized by a primer cup that is crimped into the base of the cartridge case, with the priming compound located in the center of the cup. This design contrasts with rimfire cartridges, where the priming compound is in the rim of the case.

Centralfire cartridges are generally considered more robust and reliable than rimfire cartridges. The central position of the primer makes it less susceptible to damage during handling and storage. Furthermore, centralfire primers can be made larger and contain more priming compound, leading to a more consistent and powerful ignition of the propellant. This increased reliability and power are key reasons why centralfire ammunition is widely used for most firearms, including handguns, rifles, and shotguns, for hunting, sport shooting, and military applications.

The manufacturing process for centralfire cartridges involves inserting a percussion cap containing the priming mixture into a primer pocket in the base of the cartridge case. The case is then crimped to secure the primer. When the firing pin strikes the primer, it ignites the priming compound, which in turn ignites the main charge of gunpowder in the cartridge, propelling the projectile. The ability to reload centralfire cartridge cases is also a significant advantage for many shooters.
