Turkey was almost extinct on Long Island during my years growing up there. For about 10 years now they are quite prolific on the east end of the Island; talking big birds too. Now at times you can see many along the side of the highway. Secondary roads they are as bad or worse than deer.
Leave that alone for the moment.
So, I was fortunate enough to grow up on a beachfront home south shore east end LI. No Turkey,but ducks & geese abundant and we would bang away off in a beach blind until steel shot became law.
Oh crap, a cluster for sure.
Open up chokes, this and that....
Finally got tired of that and bought an Armsport 2700 O/U Goose Gun. That was the cannon that brought the house down. It was heavy, 32"barrels, didn't kill ya with recoil although then I was younger but got it done.
12-3" were just touching them, 10-3 1/2", down. Steel shot ruined everything at the time.
That 10ga evened the score. Cost plenty more to shoot but we didn't cripple as many birds either.
