The .50 Peacekeeper is a wildcat rifle cartridge that was designed by J.D. Jones of SSK Industries. It uses a .460 Weatherby Magnum case that has been re-sized to accept a .510 in (13.0 mm) diameter bullet.^[1]

The .50 Peacekeeper is usually loaded with bullets that weigh in the range of 650 to 750 gr (42 to 49 g), and with muzzle velocities that range from 2,200 to 2,400 feet per second (670 to 730 m/s). A 750 gr (49 g) bullet fired at 2,205 ft/s (672 m/s) carries roughly 8,100 ft·lbf (11,000 J) of energy. Recoil in a 12 to 15 lb (5.4 to 6.8 kg) rifle is slightly less than that of a 30 lb (14 kg) rifle chambered in .50 BMG.^[2]
