learning to shoot a BT doesn't take a day or week....it could take months to get comfortable with it. The year I learned I shot it exclusively for 5 months. Set my bow back up for my trigger release and it was night and day. have not had TP since and very few have higher averages on the rubber range. If you are a trigger puncher, you will kill deer. If you want to become a good shot, you will need to learn how to stop pulling/punching the trigger. If you didn't know, talk to any good target guy. They won't tell you anything unless you ask. It's kind of a don't ask, don't tell type thing.
BTW,never had TP on a deer and rarely on a foam critter. the smaller the spot I was aiming for the more likely TP would "happen'.
