"...You shoot anything in the head it's gonna pretty much die..."
Maybe, maybe not.
You've got that right! Years ago I drove a milk tanker for a living, driving to dairy farms to pick up their milk and run it to the dairy. At one farm, after hooking everything up and starting the pump, I figured I'd go sit in the cab and read a magazine while the pump did it's work. So I'm sitting there when the farmer's two sons pull up in a pickup towing an empty cattle trailer. They then lead a cow into the trailer, turn her around and start back out, stopping where they can close the door of the trailer on the cow's neck, and then jam a piece of 2x4 into the door to hold it in place. I'm sitting there with a puzzled look on my face trying to figure out what they're doing. Well, the one shows up with a .22 bolt action and shoots the cow in the forehead.
Nothing. No effect at all.
He chambers another round and shoots again. This time the cow goes down on her front knees. The other kid starts cutting her throat! At first I was shocked, and then I got angry! I got out and told them to have the decency to kill the poor creature before you start sawing on her, drew my .45 and put a round just above her eyes.
They weren't happy about it saying it would destroy too much meat, but I told them they have the obligation to kill the animal as quickly and painlessly as possible (and that they needed a bigger gun!).
