I'm 55 but in very good shape. I hear you about recoil and I was considering a 16 or 20 for that reason. I used the smallest loads I could buy for hunting in the past. I'm not sure if I'll be after duck and geese this time but I can use the old gun if I choose that route. I'm expecting mostly grouse and pheasant. I know a 20 with bigger loads will kick just as much as a 12. My more pressing issues atm are used vs new and over under vs auto. I'm going to start fitting guns this weekend.
