Rimfire Ammo: What's so Awesome About It?
A rimfire is a specific kind of firearm cartridge that bears its name because the firing pin strikes the rim of the base of a cartridge to ignite it, rather than the primer cap in the center of the base (which is a centerfire cartridge). The rimfire cartridge rim is basically a widened and lengthened percussion cap that contains priming compound, and the cartridge case holds the bullet and the gunpowder.

Originally, the velocities were extremely low, even close to that of an airgun. Then in 1857, the .22 Short was created for Smith & Wesson’s first revolver, utilizing a lengthier rimfire case and 4 grains of black gunpowder.

Today, the .22 caliber rimfire ammo for sale is all that remains of the earlier rimfires.
