Don't know about that as I seem to recall reading quite a few articles of late about people surviving being shot in the head.A hit to the brain-housing unit will do the trick regardless of the bullet type.
I suspect that many of those survived head shots were due to those nuclear/lung blowing 9mms I keep hearing about.Sure...a glancing shot in the head with a small caliber is survivable.![]()
A .45 crashing through the sinus cavity and brain is a stopper.
