ORIGINAL: Red Hawk
I was wild pig hunting......... I was using a .300 Savage Magnum with scope...........hit at the base of the neck/head and she dropped instantly.
Did it decapitate it??

Sorry, just couldn't help it. That's a large pig rifle.
Anyway...........
For me.. my favorite kill shots are the lungs/heart every time with the double lung my favorite. I think if you hunt big game you are risking waaaay to much and would highly recommend you stay AWAY from the shoulder no matter what on an Elk. You will chase alot for miles and wonder why you never found them more than less shooting there. Works for some game, but why chance it? Hole in the lungs or heart only has 1 result... DEAD and they usually don't run that far.
