I have shot at one turkey with a 20. I was squirrel hunting with #6s a standard field load and a flock of turkeys was coming toward me. It was fall season for turkey. I waited till They were as close as I would shoot a squirrel. I picked out one with the longest beard and flattened it. I stepped it off and it was 35 yards. I figure if the gun will kill a squirrel it will kill a turkey head.
