I was asking TxAodadKlr, I already know you are a very good shot stx. I have never seen an animal run that far from a well placed shot with either an arrow or a bullet.
Shoot enough of them and sooner or later you'll see several.
Sometimes I think they simply don't realize they are dead, other times I think it's that they are so hopped up with testosterone and natural cortisol from all the fightig and sometimes I think it's just totally inexplicable.
Years ago I shot what then was the biggest hog of my career, a big, nasty black boar with a long silver stripe up his nose and down his back.
At 400yds I laid an absolute perfect shot on his right shoulder, broadside, with a 140gr accubond in a hot 7RM. I made the shot and saw it hit as perfectly as anyone could hope for. Just between the point of the shoulder and the elbow drilling the heart and both lungs.
He makes about a 200yds circle looking for what "bit' him. Stops, looks around, and makes about a 300yds circle. Stops, and looks around, then takes off heading west like he had a rocket up his butt.
He runs about 300yds through one steep creak and up the other side and dies in the bottom of the next one some 150yds away.
We got there and opened him up and there was just nothing left inside of his chest that was recognizable at all other than the bottom half of his heart. Everything else had been turned intot red jellow.
I had to gut him right there and then went and got a horse to drag him out to the field so we could get him into the stock trailer with some considerable help.
Even at that he field dressed 590lbs.
My big stud zebra was hit the same way as I described as my preferred shot, straight on head up center of the chest just above the sternum with the 375 Ruger shooting hornady interlock 270gr.
Hit him dead smack on which punched straight through the heart and he ran about 300yds before getting into an opening where I quickly put another one through the triangle on his shoulder. We found him dead about 40yds into the bush.
By rights both of those animals should have hit the ground stone dead.
Sometimes, they just don't want to die.
