I think its the pull to the right every time you release Jake, (correct me if I'm wrong Jeremy) it wont allow the arrow to leave the bow smooth, any drag here will reduce the distance. Have you read Toxophilus, and the Art of Archery both books contain very good information on how you should shoot a bow. Namely holding the string on the 2nd groove of the first finger, middle of the middle finger, and the last groove of the ring finger. That puts your arm in a position where you can draw and release better.
