I took my 500 JRH and my 460 S&W to the range today. Here's my numbers (5 shot averages):

500JRH. 5.5" barrel Ruger Super Blackhawk. 29.1gr H110. 440gr WFNGC. Winchester Large Pistol Primer. Starline brass. 1231 fps. 1,478 FPE.

500JRH. 5.5" barrel Ruger Super Blackhawk. 10.6gr Titegroup. 440gr WFNGC. Winchester Large Pistol Primer. Starline brass. 985 fps. 948 fpe.

460 S&W. 14" MGM ported barrel on TC Pro Hunter. 40.5gr H110. 300gr XTP MAG. CCI Large Rifle Primer. Hornady brass. 1948 fps. 2,528 fpe.

Here's what I learned, that I was surprised with-- The 300gr bullet out of the 460 S&W hits HARDER than a 440gr bullet out of the 500 JRH, even though the 500 JRH is a much heavier bullet! The 440gr WFNGC is almost 50% heavier than the 300gr XTP MAG! I didn't know that velocity would make up THAT much difference! I mean, we are talking a difference of just over 700 fps, but it translates to a difference of 1,050 fpe! I would NEVER have expected those numbers!!!

And all this time, I thought the 500 JRH was the hammer!
