I don' t like to pick but your problem is most likely form related. You need help with that as the others have mentioned. Although a well tuned bow is a more forgiving one it really doesn' t help with accuracy as much as consistent form. Even a poorly tuned bow will shoot very good groups. The arrows will just look ugly geting to the mark. You need to get with some good ARCHERS to help with your form and concentrate on this and not group size or bullseyes or anything else. With better, consistent form all the other stuff will fall in line. And it won' t be aquick fix. It takes time and diligence.
