@gungasnake,
Ive got 3 12 gages, the Browning O&U, open and mod choke) an Ithaca pump (no choke), and an older Xpress Double Barrel that I use most for hunting small game.
I always fire 6's for small game'4's for ducks and 3's for geese. Ive gotten some big ball and )) for home defense and those , being long brasses, do kick like a mother.
With nice recoil pads on all of em, I and my wife dont have any trouble (Although she prefers a 20 gage O&U for when she goes out hunting dinner.
Ive shot doves using 9's but Im not too keen on dove slaughter , its a wste of meat
Ive got an antique rabbit eared 10 gage and several dozen old shells that were solid brass, Ive never fired em. I just emptied em of shot powder and primers and have used em for wind chimes.
