What about the animal being shot through the rib cage during the respiratory pause, after exhalation? It is possible to go through the chest cavity at this moment an not hit a thing, imo! Something else I wonder about, a double lung shot with inflated or deflated lungs, which does the most damage? My thinking is when the lungs are at their smallest volume of air , again during respiratory pause after exhalation. I am thinking with an arrow or a bullet, a certain percentage of shots can appear to be kill shots , but hit nothing but hide and ribs!
