The 500 JRH aka the 500 S&W Short magnum is a cartridge that can have two loads to use. One for anything close in the lower 48 and one for everywhere else when massive animals who can kill you are hunted. The bullet is a 440 grain hard cast gas check flat wide meplat at 950fps from Buffalo Bore and another using the same bullet at 1350fps from Buffalo Bore. And Max Prasac used a 340 grain Cutting Edge Bullet of solid copper and flat meplat in his BFR 500 JRH to drop a huge Cape Buffalo as well as a huge bull in Argentina as a test run for the Cape Buffalo of Africa.
