I've gotten my friend into bow hunting this year and we've only shoot at my block target. He was talking about we're the vitals are and where to hit the deer so i pulled out a vitals poster I got in a magazine taped it to the block and we started shooting at it.

Before this he was grouping his arrows pretty good about the size of a half dollar or so but at the poster he was all over the place. I don't know if he was tired or what.

Has this happened to you or someone you know?
