That one reminds me of a hog my mother shot behind the ear with a 140gr SGK in a 7mm RM.
Hog went down at the crack. After a few minutes goto up and walked to a tree about ten feet away and fell over.
Mom ask me to go get it, so off I go in my dune buggie. Took no guns or bow.
Got to the tree...no hog...some blood, so I start tracking. Found her about 15 yards from the tree, reached down to grab a leg...she jumped to her feet and took off. She only ran about 20 yards and fell over.
We did this two more times. We were getting farther and farther from the vehicle so I decided this was going to end now!
So as I got close to her I took off running so I could jump on top of her. I was able to knock her off her feet, then put my hunting knife to work!
Then had to drag her twice as far as I should have.
You could have put a golf ball though the hole in her neck, but a hogs spine comes out the lower bottom of the skull, not right out the back. I hate it when I hear guys say to shoot one behind the ear.
There is nothing there, but meat!
