One last thing I would like to add. Practice how you plan on shooting. I hunt exlusively with my bows. I will shoot from odd spots on my range. I will climb trees around my house to shot from. I will also shoot from odd distances 15 yards, 27 yards, 38 yards 42yards ect. This will help you judge distances. I try to train my game as well as my shot. I also like to shoot a couple of rounds first to cause some fatiuge. I know this is not good and depends on whether you still hunt or not. If you do some still hunting you might have to work a buck for a couple of miles before you can cross him and take a shot. If you havent learned how to calm yourself and relax after you are tired the shot is worthless. I guess this would only apply to those who like to get out and stalk.

As for the shot, dont worry so much on where you are hitting when trying to correct the problem worry more on form. Like dic-cress mentioned the follow throw is one of the keys to accruacy. Practice it every time you shoot.
