I took my bow and arrows up to the pro shop today and told them about my grouping problem. They asked if my broadheads were lined up vertically since I shoot 2 blade heads. I told them they weren't. They said I couldn't shoot accurately if they weren't lined up. I thought this was a bunch of crap. He said to get some o-rings and put them on the bottom of the heads. Then he told me to turn them until they were lined up with my bow string. There was a guy there that had some o-rings. I put them on and brought my bow home. I could have sworn after I left, everyone was laughing at the prank they just pulled. I got home and took my first two shots. Both were bulls-eyes. I was amazed. Does this sound like it could happen?
