.50 Peacekeeper

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 diameter bullet.

The .50 Peacekeeper is usually loaded with bullets that weigh in the range of 650 to 750 gr, and with muzzle velocities that range from 2200 to 2400 ft/s. A 750 gr bullet fired at 2205 ft/s carries roughly 8100 ft.lbf of energy. Recoil in a 12 to 15 lb rifle is slightly less than that of a 30 lb rifle chambered in .50 BMG.
