The .224 BOZ is a (UNKNOWN) cartridge with a Bullet Diameter of 0.224 in” (5.69mm) that is primarily used in Pistols. The .224 BOZ originated in The United Kingdom in Approximately the 1990s. The .224 BOZ also has a case length of 0.909 in” (23.09mm) and an overall length of 1.283 in” (32.59mm).


The .224 Boz, originally intended for use in the Glock 20/29 and H&K MP5 with a modified barrel, is an armor piercing round created by Civil Defense Supply. In its infancy, the .224 Boz cartridge was based on the 10mm Auto cartridge, necked down to accept a .223 Caliber Projectile, despite it being named after the .224 caliber size, commonly associated with the .224 Weatherby Magnum which is a rifle cartridge. In recent years, it has been reworked into the smaller but still efficient 9x19mm Parabellum (Luger) cartridge, with the projectile remaining .223 inches (5.6mm).

The .224 Boz Cartridge arrived on the scene around 1999, and was an original contender in the NATO trials that also included the 5.7x28mm (FN 5.7 P90) and 4.6x30mm cartridges. Several other cartridges of this type have come on to the scene in recent years such as the very impressive 6.5x25mm CBJ created by CBJ Tech AB of Sweden, which provides impressive velocities in a variety of different cartridge variations for all scenarios.
