Sharptop:
My problem is the only one in that batch that's mine is the .475 Linebaugh Freedom Arms 83, with a 7.5 inch barrel.
Jack made it target grade accurate, and, it shoots one hole at 25 yards, if you will. So, I couldn't very well have him mess up a gun that shoots one hole, by chopping the barrel.
I WANT a shroud length 500JRH, just like Jack's BFR, but, few other things are in the fire right now. That's Jack's house packing gun, when it's dark, or otherwise. I've shot that gun, and it was just a piece of cake with the 440 grain loads.
REcoil was calculated at 25 ft lbs of energy, which is heavy 44 mag.
I've also shot this gun:
The .500JRH and the 475 Linebaugh use essentially the same loading data, so recoils going to be the same. You didn't post bullet weights or velocity on those loads you've shot, and, I've only shot Jack's ammo, and, my handloads, or Hornady 475 Linebaugh 400 grain XTP's at
1350 fps.
If you are an experienced 5 gunner, the 500JRH simply provides the most penetration and punch, in the smallest shootable package I know.
Jack also has a little 500, on a Ruger. 350 grain bullet at 850fps.
I'd love to have both a Ruger Alaskan, and, a FA 83 in .500JRH. I think it runs about 500 dollars for each conversion.
