[QUOTE="Buffalobob, post: 165616, member: 8"] Shawn's bear shot is a good example of why sometimes an animal does not die immediately and in fact may even recover from a chest wound. It is also the reason I am alive today. A chest wound is fatal for a few reasons: 1. It hits the heart or a major artery and kills the animal through blood loss to the brain. 2. It opens up the chest cavity to the outside air so that the diaphram cannot develop negative pressure, thus depriving the animal of oxygen to the brain (same as no blood to the brain). This is known as a sucking chest wound and every infantryman is taught to rip open the bandage, slap the plastic cover over the front of the wound and rolll the guy over and check for an exit and place a piece of plastic (cigarette cellophane works) over it and then wrap the bandage as hard and tight as possible to seal off the holes(insert a hard item over the plastic if there is not pressure from the bandage). So very many infantrymen lived in Vietnam becuase if you sealed the hole, the lungs themselves can and will function with the holes through it. Many people only have one lung and still live normal lives. I knew a guy who lived when an RPG stuck into his chest without detonating and I actually saw the scars on him and it was gruesome but he could do PT and runs miles with me. He lived because no one pulled it out of his chest and the medivac choppers got to him quickly. What happend to me was not nearly as heroic nor interesting but it is very common for a lung to have a thin spot and just "pop" and deflate. I was training for a marathon and went jogging in subzero weather and one of my lungs just popped. Three days later I mentioned it to my wife who immediatley recognized what it was and threw me in the car and off to the hospital where I spent three days and got two new scars. So the only way a double lung shot is effective is if there is enough internal damage to cause a system failure or if there is an opening to atmospheric pressure so that they cannot inflate. I have never killed a bear (and hope to remedy that soon) but it is common with large hairy animals for the hide to move and cover over the entrance and exit wound enough that the animal can still get the lungs to inflate sometimes and get enough oxygen transfer to the brain to keep going. Rember a lot of people function with only one lung, so 50% lung capacity is about all that is needed to remain concious and mobile. Buffalo, elk, moose and bears have a lot of floppy excess hide and once the blood gets on the hair it can matt and form a seal so the wound is closed off. All of that said, if I had to choose between a varmint type bullet and a FMJ I would go with the FMJ everytime because the odds are that enough damage will be done and the hole will not seal. Plus an FMJ will break a lot of bones. Another thought is that more sectional density is better than less. Bigger calibers punch bigger holes even though I prefer to hunt with the smaller calibers.
