What parts are in a rimfire cartridge?

A rimfire cartridge typically consists of three main parts: the case, the primer, and the projectile (bullet). The case is usually made of brass or another metal and contains the primer and gunpowder. The primer is located in the rim of the cartridge and ignites when struck by the firing pin, igniting the gunpowder and propelling the bullet forward. Rimfire cartridges are distinct from centerfire cartridges, which have the primer located in the center of the cartridge base.
