I don't own one. Yet. But after spending this past weekend with a few on here, I have a feeling it's a matter of time before I do. Thanks 45MAN, Whit, Tradmark, Bigbrowndog, Kinger, Cherokeetracker. You guys are baaaaad influences...

Anyway, I've been researching this caliber a lot the past few days and load data for jacketed is anemic at best. Even when looking at 475L and 500WE, there isn't much to go on. Other than Hornady XTPs of course.

Ok. The 500 SW case is 1.625" long. The 500 JRH is 1.4" long, or, 86% of the SW parent cartridge.

For easy math, let's say the upper limit on a 325 Barnes XPB for the SW is 45 grains of H110. Is it safe to say that 86% of that charge would be a safe upper limit for the JRH?

I'd really like to find some data on the 325 A-frame, but that is more scarce than a beautiful woman who isn't also crazy.

Thanks in advance.

Randy, it was a pleasure! Glad you could make it!

I've got lots of good load data for the JRH. Let me dig it up and post it. A friend of mine did some really early load development and compiled it.

The 500jrh benefits from manufacturer support of reloading components. It?s a pity the selection of .51 non lead bullets is so anemic.

It is a good round, Max I hope your friend is someone knowledgeable and not a fly by night poser!!!
Randy, it was a pleasure as well.

The only thing to keep in mind with the Barnes XPB is their length..they will change that equation...they are very long (nose) for weight

The Linebaugh is a classic and the one that started it all but the JRH really benefits from the popularity of the S&W and that's the main reason I chose it. LOTS of great bullets with manufacturer incentive to develop more like the Lehigh solid. After this weekend, I'm thinking that next year I might slap a big bison with mine and the 440gr WFN.

Beautiful gun Craig. Too pretty to pack out in the bushes where I hunt. Who built that?

I don't own one .Yet.
Randy they got you on a slippery slope, on greased skis with there hand on your back helping you along. You drop over the edge no climbing back up.

Push him boys!

Jack Huntington built it.

That's why I made a full flap for it.

Trapr, he is the one who killed the first head of big-game with a .500 JRH, the recipient of the first one built by Magnum Research, and he worked closely with Jack on load development.

You can use FA 500 WE load data for the 500 JRH

Thanks everyone!

Craig - sorry forgot to include you in the list up top. Enjoyed getting to know you as well. And MERCY, what a gorgeous handgun! Nice leather work too!

Junebug - ha, you ain't kidding! More like a kick down that slope. I never should have shot the BFR with their Bisley grip. I'm a believer now.

It was a really educational weekend. Thoroughly enjoyed it!

At one point my wife texted me and asked how it was going, since I'd never met any of these guys in person. My response..."well I'm having a blast - I'm surrounded by handgun hunters and a gunsmith who is the Rain Man of revolvers". She responded with, "So I guess you're never coming home..."
