If you are not aware of, the working principle behind all bullets is more or less the same. All bullets have a casing, the gunpowder, a primer, and a bullet. It is the firing pin of the bullet that hits the primer to create a small explosion. It is this small explosion that sets off the gunpowder, and the bullet is propelled out of the barrel of your gun. The location of the primer is what makes all the difference between a Rimfire and a Centerfire cartridge. In a Centerfire cartridge, the primer is located at the center of the base. On the other hand, there is no special primer in Rimfire cartridge and the priming compound is in the rim. When the firing pin hits the rim, this priming compound is activated, and this compound activates the gunpowder.
