If you watch all the hunting shows they all do it different. I don't think there is a set way to do it. I treat deer kind of like I treat a big gobbler, I call enough to keep them intrested but I try to make sure I don't over do it. Here in Mississippi the deer don't seem to react to calls very well at all, but when I get to hunt in Iowa they respond very well. I just try to feel it out especially if you can see the deer just watch how they respond. I'm no professional by any means but that works for me. Oh and in Iowa the Primos can and Buck roar with a litte aggresivness worked for me.
