Yes, QDM is the best thing to ever happen to deer hunting. Passing up the smaller bucks is always a good feeling, because you know that basket 6 you just passed up could be a 140'' 10 pt in 3 years. My group uses QDM very strictly, and we only shoot bucks that score at the minumum of 125'' gross. Most of us won't shoot a buck unless we are certain he is at least a 3 1/2 P+Y book.
