I am seeing a sh*t ton of videos on you tube made by so called experts at killing deer but about 95% of them are shooting expandables and shooting 70 lbs but when they put one in that 200 lb buck the deer runs off with 3/4 of the arrow sticking out the entry side without even bustin through the opposite rib cage. My goal and in my opinion what should be every bow hunter's goal is a complete pass through especially if it's not a perfect shot. Two holes means more blood especially if the deer was shot from a tree. In that instance you really need that bottom hole to make a great blood trail.
