My son blew one THRU the shoulder of his buck last year. I informed him to NEVER take that shot again but he was so sure he could do it. Well he did. Quartering to him and thru the shoulder, both lungs and out the other side. I would not have believed he would get a passthru at 18 yards thru the shoulder. Oh and no damage to the head. For the record I will still stay with my SlickTricks. I like the blades ready for action when they arrive.
