I was watching a hunting video the other day and there was a guy on there going after trophy whitetails. I don't rmember the guy's name, but he was in a really good spot. A nice 10 point walked in and it was aproaching him. He started to grunt and the buck took off. I thought he had grunted to much. I try to limit it to just a couple grunts, he did twenty or thirty. How often do you call and what call do you do it with? What is the limit before it becomes overcalling?
