The .500 Bushwhacker is a .50 caliber semi-rimmed revolver cartridge developed by TII Armory for the Magnum Research BFR revolvers. It is currently the most powerful revolver cartridge in the world, offering a similar level of ballistic performance to African stopping rifles, such as the .416 Rigby and .470 Nitro Express. Given comparable barrel lengths, it is nearly twice as powerful as the .500 S&W Magnum.[6] A 10-inch barrel revolver chambered for the cartridge is capable of penetrating 103 inches of 10% Clear Ballistics gel. A 24-inch barrel rifle chambered for the round can penetrate 127 inches of the same medium.[7] A 14-inch .500 Bushwhacker revolver can exceed 3,000 ft/s (914.4 m/s) with select loads.[7]
