I agree with Mez. Try shooting open handed and see if they hit where you were originally. If you do, you know you' re either torquing the bow or peeking (dropping the bow to see the arrow strike). If you' re left handed, and you' re canting the bow to the left, that can cause you to hit to the right. And finally, don' t shoot too much. Sometimes you can get tired and that will throw your form off. I wouldn' t shoot more than every other day. Your muscles need time to rejuvenate.

Almost forgot, if you try shooting open handed, use a wrist sling!! I' ve had situations where I shot this way without a wrist sling. The good thing is, you' ll know immediately whether or not you' re gripping the bow at the shot or not. The bad side of it is, you' ll have to clean mud off the bow when it lands on the ground.
