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.
