Energy is a scalar, not a vector ie. it has magnitude only. Once energy is turned into work, we're using it - work is a vector ie. it has magnitude and direction.

Funny in light of the fact that you're trying to bend the laws of physics to suit your point; energy by itself does zero
unless it's put to work. I honestly believe that you simply do not understand that fact of physics.
After reading back through my post's I don't believe I misused the term energy in any way.

Two bullets fired at a body 15" thick.
Your bullet penetrates to 6" inside the body and stops - mine penetrates all the way through 15" and exits out the back.
To use your terms, the first bullet may have, as you put it, "expended all its energy" and the one which over-penetrated still had energy remaining - right?
So, while your bullet at 6" deep might have been more efficient in using all its energy (100% usage) versus mine which used say, only 50% - the fact remains that my bullet which penetrated all the way through crushed and destroyed 9" more tissue through the body.
Quite simply, mine did more damage (even though, in your terms, it was less efficient in terms of using all of its energy).
Yours crushed a volume of 2.31 cubic inches of flesh (the volume of a .35 inch dia, 6 inch long cylinder) - mine crushed just under 5.8 cubic inches of flesh (the volume of a .35 inch dia, 15 inch long cylinder).
Quite frankly, if your bullet stopped earlier, it's because it was weaker - despite the fact that "it expended all its energy".
Agreed

Would it be even more efficient if your bullet stopped right on the guy's breastbone? Surely it would - it's "exerted all its energy", so it must be good - right?
No, It would be the same efficiency. 100% And that only works in the matrix.

Wound size matters - efficient use of energy? Who cares. Efficiency of energy is irrelevant; doing as much physical damage as possible along the way is.

As long as that damage is to the person intended, then I agree. But as I stated before, I don't want to risk collateral damage. I know you don't like the "what-if" game, but suppose the threat was in your house with your kid in the bedroom behind the bad guy? What if it's a skinny crack head 10" thick.
Irregardless (yes, that's a word), Just giving my 2 cents.
pa-lease... Nowhere have I stated that I believe a bullet can magical create it's own energy. I've stated a mere fact that my bullet used all it's energy and therefore stopped, where as yours continued out of the body.
