I did this on my first few deer with a bow. Luckily I still got them because they were just chipshots (15 yds). The last one I shot I actually held the pin on the chest for about 15 seconds before shooting. That 15 seconds was AWESOME!!!! Force yourself to hold for a while - it's the best feeling in the world being at full draw and KNOWING YOU GOT HIM before you even shoot. Savor that moment - it doesn't get any better than this!
