Well for me. Call them to less than 20 yards and it dont matter what shot size you use. What gauge shotgun you use IF YOU HAVE PATTERNED CORRECTLY.
At 20 yards the cheapest 2 3/4 shot gun round works. I dont care who made it
And you save money over that high priced turkey rounds.
But that is me and the goal I use to Turkey hunt. Less than 20!
