Well, they've been killed by longbows for centuries, so I'll guess about 50. It's probably lower than that actually.

Energy is a poor indicator of wound trauma incapacitation. A bullet strike is an inelastic collision and energy is not conserved in an inelastic collision, instead it is transformed into other forms of energy (mostly thermal ). Energy is only conserved in an elastic collision. Momentum is conservered in all collisons

The going number on this sight is 1000ft lbs or 1600fps.

Then how does one kill a Deer with a 45 ACP? the 45 ACP kills them very dead very quickly BT/DT. How does one kill a Deer with a Bow and Arrow since it take a rather heavy draw compound to reach 80 foot pounds?

Not getting in to this one due to many different variables to each. I saw Ted Nugent shoot a deer at 100yrds with a 10mm. It ran away. He stalked it and shot it 3 more times up close and it still ran. So I'm not real sure what your going for hear, a ******* match or just that fact I was offering a suggestion? Depending on bullet, ability and equipment will determine what works. These are the numbers that I have been told and well it just makes sense. More for elk, less for deer, and ever less for varmints. I don't know, go use a sling shot for all I care, I'm just trying to offer some information that I think would be helpful. This energy and foot pound thing has been talked to death and quite frankly my thoughts are shoot as far as you are capably accurate to shoot in the vitals.

.308's are to be a worthless caliber for 1000yrds to kill something, but snipers are knocking taliban over at 1000yrds with this worthless caliber. I have talked to several snipers and know one personally that spent 4yrs in the jungles of Vietnam that has killed men to 1800yrds with a 300 Weatherby. So you pick the numbers and the calibers and tell them what you think he should use. I'm just offering advice.

Re: How much Energy to kill a Deer?

A 22-250 with a 55 grain bullet at 3600 FPS has 1583 foot pounds of energy is it a Deer Cartridge?

A 475 caliber 385 grain hard cast at 1300 FPS has 1445 Foot Pounds, which one would you want against a Grizz


I know which one that I want and it ain't the 22-250
