Hard (dang near impossible) to say without more information, or actually seeing you shoot. One thing that might help though--start over. Get really close, concentrate on your form. Shoot some close targets. Be positive--you know you can do it, you did it before, and you will do it again. Sooner or later we all hit a slump--sometimes without a clue as to why. Just hang in there and you will figure it out.
