500 JRH Firearms at Western Gun Store

The .500 JRH revolver cartridge, designed by custom revolver builder Jack R. Huntington, was originally created specifically to allow use of a rimmed .50 caliber cartridge in the Freedom Arms Model 83 Revolver. Its case is 1.400 inches in length with a base diameter of .526, and it launches 400- to 510-grain .50 caliber bullets at velocities comparable to the .500 Linebaugh.
