[QUOTE="MontanaRifleman, post: 333310, member: 11717"] JE, that was a good post and I basically agree very generally with everything except that energy is not what kills from bullet wounds. Game anaimals die from hemoraging or major CNS damage when shot by a bullet. Actually they die from lack of oxygen to the brain which is caused by extremely low blood pressure, which is caused by hemoraging or the severing of major arteries. Energy is only involved in an indirect way and that's why I dont look at energy for determining a bullet's potential to kill. Energy transfer is a product of the destructive forces of a bullet meeting bone and flesh, it is not a causal factor of tissue destruction. The right combination and design of mass and velocity (momentum) are what cause destruction to living tissue. JWP posted a good example of a 22-250 vs a 475 for taking a bear. A lot of deer are very adequately taken with much less than 1000 ftlbs of energy with shotguns, muzzleloaders and handguns. This is because of the size and construction of the bullet. On top of that, deer come in a great many sizes. Having said that, 1000 ftlbs of energy is a fair but very rough wag of most modern rifle's bullets potential to kill deer in that it reflects a combination of mass and velocity which amounts to a potential killing force. Not trying to be argumentative, but I think folks should be taking a closer look at their bullets and their game. There is a wide variety of bullets these days that perform quite differently and you can find 60 lb deer to 400 lb deer and 200 lb elk to 1000 lb elk, so to try to assign an arbitrary number with all these variables is a very very rough wag at best. Now it's time to go out and see if I can put this to practice. Cheers, Mark [/QUOTE]
