I had done a stupid thing, I began to winter bow hunt without shooting a few arrows before I got in a tree. Well I had two shots, both around 18-20yds. gave both deer a hair cut on their belly line. After it happened twice I began to wonder if it was really me. I shot at the 3-D in the yard, sure enough grouped 3 arrows at the very bottom. The problem was my launchers were worn to the point where it made a difference. I made an adjustment, and killed the next fat mama I had a chance at. I'll probably hunt again Wed. and Thurs. if it isn't 70 degrees. MWX
