Well if you really want to kill him, the only way and I mean the only way is to get in there tight to where he is roosting before daylight and not say a word, don't even bring a call because you'll want to use it. Let them fly down and scratch in the leaves all along and be ready. I have killed several hard hunted management area turkeys late in the year like this that would not come to a call. He's done heard it all you bout ain't gonna call him to you. Hope this helps good luck!
