I’d suggest two of your list of four are incorrect, 1 & 3. The kill zone is either very small (brain) or very long and narrow (CNS in neck), the very reasons I avoid this shot.There's 30 threads on here about bullet choice and wound rates, match vs hunting bullets, how far is too far etc. but i havent found one asking "Why are hunters not taking more head and neck shots?"
1. the critical hit zone on a head/neck shot is about the same size as "the vitals area" on the same animal.
2. Terminal balistics is almost not a factor.
3. If you have a bad shot, you more than likely missed the animal entirely
4. You can shoot smaller bore/less recoiling rifles with the same end ressult.
I personally always shoot animals behind the shoulder but im thinking about changing that up. Curious to hear some thoughts
There is plenty of room to punch a bullet through the neck, wound horribly, and not quickly kill the animal. Same for head shots. Count me out. But I know several hunters that employ neck shots often and well, I think.
