I get my BFR 500 JRH out of jail next month, so no load data from me. However, I emailed Starline just the other day asking them about the .500 JRH, so I'm sure one email won't do much, but if we keep bugging them surely they'll give in. Some of the brass the offer I've never even heard of, so .500 JRH shouldn't be that hard to do.
