I confess since Ruger now has some #1's in .475, it that much more tempting to get a .475 M83, as companion pieces.
At one time I reckoned a 370 grain full house .475 load in a 22" barrel would probably make 1900 fps. I don't know anyone who would call that a "mild" rifle load, yet people shoot them in pistols.
And yes John Taffin comes to mind as someone who has had a lot of hand problems, from shooting many hard kicking pistols.
