The Brenneke Special Forces Maximum Barrier Penetration Magnum™ (MBPM) was developed at the request of military and law enforcement communities for a unique projectile with which to address the most demanding urban threats. It provides the deepest penetration of any Brenneke slug, extensively tested across a number of difficult real-world situations. It leaves the muzzle of any standard shotgun carrying 3,545 ft. lbs. of devastating energy. Its trajectory is extremely flat to 100 yards and beyond, capable of fiveshot groups of 1.67" at 50 yards. As the accompanying photos and test results show, the MBPM’s extremely hard, proprietary alloy readily penetrates windshields and vehicles. It will outperform any standard rifle cartridge atclose ranges. The MBPM is not for every situation. But, when maximum penetration, power, and reliability is dictated, only the MBPM will do.
