As ya know grim there's a standing invitation to come hunt Deer, Turkey, Grouse (toughest little sons of beeches to hit), and do some trout fishing during spring turkey season (you can hunt till noon, then its time to fish)
And on that 3-1/2" mossberg...
My father has one, he shot it, he hurt for 3 days. I told him "you're going to break your hip old man", well nearly his shoulder. I havent fired it, and will not fire it. Remington 11-87 with custom stock work for me. Freehand at 50 yards I put all rounds into a 1-1/2 inch bullseye with a slug barrel, and use the same gun with a XX-Full turkey choke to shoot Annie Oakleys(27yrd trap "game").
Lets see...Dove, Pheasant, Grouse, Duck, Geese, Deer, Coyote, Squirrel, Rabbit, Turkey. All within an hour or less drive, and in some cases on the back of property. Yep...life is good when you've got a skeet range in your back yard.
The only rounds for shotguns i've been impressed with were the Copper solids they make now. Dropped an 8 point at 120 yards on the run with my 11-87 (Iron Sights, no Sissy-Scopes) on the spot. I knew something was great when i was bench shooting at 100 yards and making a 6" pattern.
Good luck with your Turkeys...I've got 2 and they're the hardest bird to hunt, while grouse is the hardest to hit.
