I have several bows, 2 black widows, 1 Bighorn-Fred era- 1 Leon Stewart and the predater that I was hunting with that day. The predater is 47#@28 with a SBD string, 550 gr carbon arrows and a Wensel Woodsman elite on the business end. My shooting is normally pretty good as I shoot almost every day, however I missed the "spot" on this buck bad! my arrow went in front on the shoulder angled down and got at least one lung, no blood trail at all, I was lucky he didnt go too far and I was able to find him.
