Antler, you are not trying to call them from a 1/4 mile are you, try getting as close to them as you can on the roost, I usually try to get within a 100 yards, also try to pattern the birds, it sure helps to try and call him in a direction that he wants to go.

Don' t give up, one of these mornings everything will work like its suppose to and you will be hooked for good.
