Back in the old days, the ole time hunters killed turkeys with 2 inch black powder shells.
I am in the same boat, so to speak.
I had rotator cup sugery.
So the high power shells are out.
If nothing else, it will be 2 3/4 12 ga shells, or mabe 20 ga.
That is If I can find one I could borrow.
Well Good Luck.
