Not to pick on you as you may just be using common terminology (and I often do as well), but a LOT of people think a head shot and a CNS Brain shot are one in the same and that isn't necessarily so, as your shot certainly illustrates. Depending on the animal, somewhere between half and maybe 75% of the head is not any sort of critical structure to immediate survival (brain or brain stem). A lot of us get away with "head shots" that don't actually penetrate the CNS via hydraulic shock, hydrostatic shock, or blunt force trauma resulting in closed head brain damage. The 6th hog I killed was like that. The shot hit the hog broadside, just below and forward of the eyes, going through nothing but the sinuses, killing the hog. It was a lucky shot and I got away with it, but that doesn't always happen. ------------ I like to make upper CNS shots when I can (distance and steadiness determining if I will take that shot), and shoulder lung shots a great distance or when less steady.
