I call anything other than a broadside deer a quarter deer. If the deer's head is closer than his tail, then he is "quartered towards" me, tail closer than the head, "quartered away".

To shot a deer on the outside of his shoulder when quartered towards you is very pathetic irresponsible shot placement. For one thing the angle can allow the bullet to be deflected so that none of the vitals are damaged. Even if the bone is pierced, it is unlikely that both lungs will be damaged. A three legged deer can go a considerable distance with one lung.

Quartered away is certainly more forgiving and I personally like "just enough" quarter away to point directly at the opposite shoulder on path through the bulk of the lungs.

In any case, whether"quartered away" or "quartered towards", high angle ofquartering shot is less forgiving and requires accurate shot placement with the anatomy of the game considered. As far as your buddy, couple the quartering away with a 25 yard shot, (probably charged high and fairly light PB), the outcome was pretty good. But the problem isn't the blanket statement "PB's break up", it definitely more complicated than that, I think you can agree.

Obviously, Mike, you don't have trouble with deer getting away. Best I can tell, your friend who uses Powerbelts isn't having any trouble either, just like the vast majority of folks that use them.
