My plans are to build a single shot bolt action pistol with this blank (similar to an XP100 remington) . I built one several years ago in 357 max and have been very happy with it. It has a 17" shaw barrel and is 26 1/2" overall. It will shoot 1" groups at 100 yards with 180gr psp handloads. On this one I am going to try the 450 bushmaster if I can find a chamber reamer. I'm also building 2 more in 44 mag for my son and a friend.
