RE: target shooting
 

Since you eliminated the arrow, how about this: is it the same shot each time that drifts? For example, always the last?

another thought is that as you stack the arrows in, the spot you are aiming at changes its look, this might make you aim off a bit.

update:
thank you guys for all of the help. Now i have the answer to what my problem was, I have to work on every shot every time! Breathing/ aiming/ follow thru/ stance /grip/ level. Shooting 1 arrow in one min., and not any quicker. I do alot of activites by not thinking, i.e. throwing a football. I'm finding out archery's mental game is alot tougher than golfs.
