The 500 JRH is 500 S&W Mag brass cut to approx 1.4" and the rims turned to fit in the FA cyl. Jack H commissioned properly headstamped 500 JRH brass which ran out -- Buffalobore now offers it - it can be made from 500 S&W if you have the ability to turn the rims (I have some of this and some orig Huntington brass).

It's a ballistic twin to the FA 500 Wyoming Express.
