Rimfire and centerfire cartridges

Sometimes you will hear people on a rifle range say, "I'm out of bullets. Please get me some more bullets." Usually, these people don't know that they are asking for the wrong thing. Cartridges go into the chamber of a firearm, while bullets go out the muzzle. A bullet is only one part of a cartridge.



The centerfire cartridge is the most common type of metallic cartridge. The primer is in the (bottom) center of the ammunition. That's why this cartridge is called centerfire. Centerfire cases can be reloaded.
