The QB-8 round is a direct substitute for standard 00 buckshot and is intended for applications where standard lead 00 buckshot is not effective or has limited effectiveness. The standard lead 7.65 mm buckshot pellets are replaced by hardened steel wedges with six pointed corners, seven sharp edges and five flat surfaces on each. The design of these pellets coupled with the hardness of the metal make them very effective against soft body armour and light metal armour. Whereas standard pellets use kinetic energy to

punch through hard targets, the QB-8 hardened steel wedges cut their way through. The pellets are carried inside a plastic sleeve to prevent damage to shotgun barrels. The QB-8 round will defeat automobile safety glass with sufficient energy remaining to completely pierce a 12.7 mm thick plywood sheet. The QB-8 will defeat NIJ Level IIA body armour with sufficient residual energy to penetrate over 100 mm of ballistic gelatin. Although the QB-8 performs well against hard targets at close range, the design of the wedge-shaped pellets cause the pellet pattern to spread at ranges beyond 25 m, which is the extreme effective range of this round. The shell case is international orange colour and is marked as to type in large black letters. By MK Ballistic Systems to provide a shotgun round for Close Quarters Battle (CQB) applications where standard 00 buckshot is either not effective or has limited effectiveness. Applications include suitably chambered 12 gauge shotguns.
