Great video, thanks for posting. I think it pretty clearly shows that energy from the bullet is transferred to the media it hits and has a definite effect.
This is one that always confuses the hell out of me. A full metal jacket bullet and and expanding one, same size and speed have the same energy if I understand it correctly. Why then does the expanding one kill beter if energy is doing any of the killen?
I think you answered your own question here. If you have 2 bullets the exact same weight and traveling at the same velocity have the exact same kinetic energy. Now taking shot placement out of the equation, say both bullets hit an animal at the exact same spot, the fmj not designed to expand will zip on thru TRANSFERING less energy to the surrounding tissue and making a smaller wound channel , this bullet also retains more of its kinetic energy and keeps traveling along its flight path. The expanding bullet as it enters the animal starts to upset or expand thus TRANSFERING more of its energy into the surrounding area and tissue while at the same time making a larger wound channel . So the chances of the second animal dying quicker is greater. The wound channel killed the animal but the extra energy distributed thru the animal I believe helped in a quick kill.
"The wound channel killed the animal but the extra energy distributed thru the animal I believe helped in a quick kill.That is a good statement.I don't hear anyone saying "energy kills the animal, loss of blood does not." The original question was looking for opinions on what is the total effect of the bullet (and energy) in the total event of shooting an animal. I got this one! It is comparative scale, right? Hit a fly with a swatter and then a bear. The results are different because of the comparative scale of the weapon to the target. Now what happens when you hit a ground squirrel with a .22/250? The critter comes apart. Pretty hard to say it dies from blood loss do to a bullet wound.

Here is an Elephant a friend shot last year type of bullet and velocity is a key factor to slow not enough penetration to fast defections and tumbling. Blood loss did not kill this critter.
I never thought of it the way you describe. But Blood loss in a millisecond second? The hart would have been on its last pump.
The wound channel needs to be defined perhaps. If you look at the path of a bullet through a media the wound channel is much bigger dia. that the bullet. If energy is the cause of that part of the wound channel then energy has a big effect on wound channel and therefore DEATH.
But that isn't what the movie shows above. It shows the bullets coming apart making a big wound channel but the x-bullet almost cutting its way through and not much more. Does that mean the energy isn't being used there??? Why not if anyone nos.
I'll throw a wrench into the whole deal and say this: I don't really give a rats azz about energy numbers, at the muzzle, or at distance. Velocity is where it is at. Most bullet maunfactures publish maximum and minimum impact velocitys for specific bullets. Thats what I tend to look at. The energy numbers tend to turn into gack, and don't mean a whole bunch in the real world.R.
