You asked...How long was it before you got back to regular hunting weight bows and longer shooting sessions?
The question may be, define regular hunting weight?
I had RC surgery in 2012. While daily life activity is fine now, drawing anything much over 40lbs is tough. Same with throwing a baseball with my kids, overhand fishing/casts and if I golfed, I imagine a golf swing would be tough.
I started getting soreness and some weakness again this past December and saw the surgeon again, who happens to be the top surgeon in the area and who has assisted on some of the biggest sports names in football and baseball.
He said that even though it was a year out, that I may have to do my daily rehab/stretching/strength training for another year. Long story short, after going back to doing daily rehab at home, my shoulder feels much better.
The bottom line is, I'm likely topped off at the 40lb mark, with 35 feeling much more comfortable. I can shoot 35 all day and it's comfortable. I tried to draw a 44lb 1959 Alaskan yesterday at Black Dog Outfitters and it wasn't happening.
That said, if you get to where at 37lb bow feels comfortable, you can kill deer all day with 37. Unless of course, your state has antiquated minimum weight rules, back from when they thought you couldn't even kill deer with a bow.
My advice would be to first talk to the surgeon and take it slow. Every case is different. I couldn't even string a bow for nearly 6 months. My guess is, by this time next year I'll add a couple pounds, but I'm a 40-ish pounds shooter for the rest of my life and I'm totally at peace with that and have no concerns about killing all the Midwest whitetail and turkey I want.
