Gamebore Mammoth Magnum Shotgun Cartridge Review

A review of the Gamebore Mammoth Magnum Shotgun Cartridge, we look at not only the 3" but also the 3 1/2", but also at the lead as well as steel loads as well, including a recoil test, and a section where we cut open them to see what makes them so powerful.
