I had the same problem Sunday. Took about a hour to find the culprit. Changed to heavier field tip. Nope. Go back to original. Checked brace height. Good/same. String nock still in place. Same arrows I got dialed in 4 days before. Just kept shooting, maybe a really hosed release, man am I grasping for something, Check the cant of the bow, check. Anchor point same, even video'd, Check. Finally , Finally. MY grip! My grip was not the same from 4 days ago. Why did or would it change, who knows and why??? Anyway got my grip back and 3 arrows, 3 in dia on 15 yd tgt ,. Yea
