I can only recall one deer that I didn't get a passthrough on. That was the buck in my profile pic. He was slightly quartering to and I hit him a little forward of what I wanted. The arrow still buried to the fletching in his shouldar and a short 50-60 yard blood trail resulted in a dead deer.

This was from a Bowtech Allegiance at 65lbs with a 370 grain arrow tipped with a Rocky Mountain Snyper XP3. Upon skinning this deer, I discovered the arrow went completely through his shoulder bone.

What I would like to see is a comparison done of pass throughs, shot angles and equipment used, including bow weight, arrow weight, etc.

For me anyway, it really seems like a lot of people are way too concerned about the amount of KE needed to kill a deer.
