Hey Mike
Having the BFR I use Starline 500 S&W brass, I made a simple jig that allows me to cut the cases down on my high-speed arrow cut off saw. I finish them up with my case trimmer. I have sent a couple of requests to Starline over the past coupe of years asking they add 500 JRH to their offering. You never know ? If you don?t ask then you don?t get?

Starline made the original run of .500 JRH brass, and they made a run of it for Buffalo Bore to use in their loaded ammo. As such, Buffalo Bore sells the properly headstamped Starline brass. I am hoping to convince them to offer it on a much broader scale. We'll see...
