The .22 BB (AKA: .22 BB Cap, .22 Bullet Breach Cap) is a Rimfire cartridge with a Bullet Diameter of 0.222 in” (5.64mm) that is primarily used in Pistols. The .22 BB originated in France in 1845. The .22 BB also has a case length of 0.284 in” (7.21mm) and an overall length of 0.343 in” (8.71mm).
The .22 BB, closely related to the more popular .22 CB, is a rimfire pistol and rifle cartridge carries with it very low muzzle energy and low velocities, given its projectile size and cartridge length. Unlike most other rimfire cartridges, the .22 BB pistol cartridge does not have a powder charge inside of its casing, but instead relies on the energy generated by the rimfire primer. Because of this, the .22 BB carries with it very little practical use and is most commonly used for novelty shooting.
