" heck in fact at 50 yards I can shoot him in the head with a 22 lr"
Well, yeah, but that's illegal in a lot of states (many states require shotgun only for turkey)
"whats the freakin point here guys at 40 yards I can kill a turkey with a 2 3/4 inch 20 guage"
You have a 20 gauge that gives great turkey patterns at 40 yards- many don't.
If turkeys always came right in to 18-20 yards, indeed, no one would need a 12 gauge 3 or 3 1/2. Turkeys being the contrary buggers they are, often stop at 40 to 50 yards and won't come closer.
If you do much patterning of turkey guns, you'll discover that at 40 + yards, a 12 gauge 3 inch or 3 1/2 delivers a lot better pattern density than smaller stuff. Result being that the big guns will deliver cleaner kills more consistently at 40+ yards.
