I believe if your hunting out of a treestand with the angle down its hard not to clip a vital. There is a dead area there.I butcher all my animals and make all my meats myself. I would say if you hit this(dead area)you would have to have a straight on shot from the ground. Ive seen deer butchered already with wounds covered over on there chest just below the spine with broken blades stuck into the ribs. And I also seen deer butchered with a complete broadhead stuck next to the spine! Hope this helps you understand a little.
