This will be my first year deer hunting. Ive got a martin bonehunter 60# 30" draw, and im a lefty. the bow needs tuned, but for lack of knowledge i can hit groups within a 4 inch circle at 20-30-40 yards. once i get everything lined up and adjusted properly im hoping to get these groups much closer. regaurdless, have yall taken shots that were off a touch and still had a quick kill? i just dont want to go out unprepared or not have trust in my equipment. let me hear what yall think.
