Deer are pretty simular to people in size and construction, so if it would pentitrate a person it will most likely do it to a deer. If you are asking if you could kill a deer by accident when shooting at 800 yards, most likely if you are shooting anything that will reach that distance it will still have enough energy to injure an animal. A .308 will kill a human at 1000 meters with a well placed shot. Deer are not that hard to kill, they just don't respond the same to pain and will run farther when hit, and they have a better circulatory system then we do obviously. So it seems like they are harder to kill. The truth is they are dead, they just don't know it yet.

Hogs are bit tougher, but not bullet proof by any means.

The figures you see are what some so called experts say you need to make an effecient, ethical kill. And it varies quite a bit depending on what you read and who you talk to. That does not however mean a projectile moving much slower can't kill an animal. If it punctures a lung or severs an artery it will die. I mean people can kill moose with a bow and arrow.

How far the bullet would penitrate an animal would really depend on the weight of the bullet, the speed at impact and how the bullet was designed. A FMJ bullet would penitrate more than a bullet disigned to expand on impact. Unless however it it didn't have enough speed to expand.

And for the record some of the dumbest people I have met were college educated, and some of the smartest were high school drop outs. I know a few engineers that are plenty book smart, but I honestly don't know how they dress themselves in the mornings they are so out of touch with reality.
