RE: turkey hunting from a stand?
It may work - reason I say so is I see turkeys all the time on my deer stand in the woods and do raise the ole rifle to put a few in crosshairs for fun.
I have had them less than 20 yards from and do know several here have shot a Fall turkey that way while archery deer hunting.
But an elevated stand out in a field one would need to be covered to hide movement as others have told you.
