Good luck to you with the shoulder. I'm a bit over a year out from reconstruction on my right shoulder, yea my shooting shoulder. I've only fired one rifle since I got the OK from the surgeon and that was my '73 in 44 WCF. Not much of a challenge but probably a good first step. Didn't hurt a bit although the points of the crescent butt left black n blue marks. I'm turning into such a wimp as I get old (lol).
Got a rifle coming in a week or so that will test the shoulder good. Maybe after that I'll buckle my swashes and shoot a 12 gauge double. (smile)
