6.5×25mm

The 6.5x25mm CBJ is a pistol cartridge designed for the CBJ-MS personal defence weapon. Capable of use in rebarreled 9 mm Parabellum firearms, the primary loading of the round fires a sabotted 4 mm tungsten sub-projectile.

The 6.5x25mm CBJ has the same functional dimensions as the 9x19 Parabellum and was designed to produce the same recoil and pressures to allow most 9mm weapons to be converted to 6.5x25mm CBJ with a simple barrel change.
