I use to figure that if I could hold on to it, I could shoot it. I'm 64. About two years ago, I had major shoulder surgery. 90% rotator cup tear, pinned tendons, removed scar tissue, reattached my collar bone and a little more. 3 1/2 hour operation. What's bad, though, is the rehab. Doc said that either I had a major car wreck, where one braces oneself against the steering wheel, or was shooting too many high powered pistols. I tried to pass it off on old football injuries, but he didn't buy that. The strongest pistols that I shoot now is 45 Colts... in deer loads. It took me a year to get up to that level. According to a couple of experts that I've talked to since then; I should have kept my arms bent a little more when I pulled the trigger. I was shooting too straight armed and all the load was going back into my shoulders. I'm 6'2" and about 225 lbs, so size doesn't help much. Oh yea, they rebuilt my second shoulder about six months after the first. The hardest recoiling pistol that I remember shooting was a 45-70 revolver that Lane Pearce had. I think that Hamilton build it.
