I only read the first post, but i agree, rattling and calling can be affective, if it's the right time. I personally have only rattled in 2 deer, and they came running. But, it can be risky. Personally, i believe in staying as quiet as you can and being in the right place based on your scouting, and i've shot all my deer based on that. Bowhunting is about being un-detected, stalking your pray, ambushing, or knowing what the animal is going to do. Rattling will do you no good if you are not set up right. So don't rely on it to get you the "Big One". However, when the situation is right, it can be a blast.
