My advise is forget the open fields and your rifle. Get in the woods and thickets with a shotgun. Start out calling softly then louder as you go. Sit still.
Prime example;
Those guys that hunt Arkansas with the mouth calls on you tube. Never see them in an open field.
I live in Southern IL and havent taken my rifle hunting in 3 years. I have great success hunting in the woods and all my buddies are constantly crying they cant call em in while hunting the fields and they wonder how Im killin them. Last winter I hunted with a friend, as a guest, on a field edge with no luck. We both know they are there. Next day I set up, by my self, 60 yards from the field edge from where we were the day before, inside a dense woods, and scored a triple. Went back to the same spot that evening and the a single.
Give it a try
