Centerfire and Rimfire Ammunition for Handguns

Ammunition can be centerfire or rimfire.

• Centerfire ammunition is used in handguns. The primer is located in the center of the casing base. Most centerfire ammunition is reloadable.
• Rimfire ammunition has the primer contained in the rim of the ammunition casing. Rimfire ammunition is limited to low-pressure loads. Rimfire cartridges are not reloadable.
