I'm just curious, but did you have your finger on the trigger when you drew? I actually got to watch my son do that same exact thing last season while drawing on an 8 point. It was his first attempt at a shot on a deer, and he made the mistake of keeping his finger on the trigger through the draw. He was drawing on a decent buck and launched the arrow into the next county. (I still rib him about that.)

Sorry about all of the bad luck, though!
