"how much is overdoing it?".......... IMHO, I think about everytime you call when you can't actually see the deer is just about overdoing it. Blind calling has educated MANY a buck! Also when you are just talkin' about grunting and bleating, your calls can't carry that far through average timber so chances are that unless you can see the animal you probably couldn't get calls to him anyway? Banging the horn together ius about the only way to get some noise out there that I know of. I will also add that as mentioned above, I would invest in a HS True Talker. This call sounds more authentic than anything I've ever tried. Good luck and good hunting
