Had that happen to me this past Monday. With opening day right around the corner I went out back and shot my bow for the last time before opening day and everything was a few inches to the left and little high. Now, I' ve been shooting just fine for the last several months so I didn' t want to blame my bow/setup, but it just had me frustrated. Come to find out my fist was grasping the bow pretty hard and it was causing me to miss...and miss badly. Just wasn' t concentrating on the little things. Good luck with whatever the problem might be.
