In some sniper movie with Mark Wahlburg as the patsy, they had snipers advising them. In an interview one of the advisers was saying how they couldn’t show in the movie what really happens. (In the movie the guy gets shot in the head and some blood flies out the back.)
The adviser said “At those ranges the bullet is going down more than across - it would enter the head but then angle down - the head would be gone, and a big slice going down the torso.” I have no way of knowing whether the guy was telling the truth or not.
I do recall the time I thought I could kill a rabbit with my .308 and still have some food. I figured a “head shot”. The round entered the head - but blew out half the body as it angled through. Learned never to try that again (I was only about 16 - stupid kid!).
There are more than few photos on the internet showing the outcome of being hit in the noggin by high speed high caliber sniper rounds.
One needs a strong stomach as it is now way represented accurately in Hollywood.
Movies with that level of accuracy may not get a rating less than NC 17.
Rabbits aren’t safe even when they’re just minding their own business:
