Centerfire ammunition is a type of cartridge where the primer is located in the center of the cartridge case. This design allows for more reliable ignition and is commonly used in rifles and handguns. The primer ignites the gunpowder when struck by the firing pin, creating the necessary pressure to propel the bullet forward. Centerfire cartridges come in various calibers and are often reloadable, making them popular among shooting enthusiasts. They are typically more powerful than rimfire ammunition, which has the primer located on the rim of the cartridge. This versatility and reliability make centerfire ammunition a preferred choice for many shooters.
