The concept of "transferring all the energy" inside the game is absurd from a physics standpoint. What would you really rather have, a bullet that hits the front shoulder with 2500 ft lbs of energy, and then penetrates and hits the back shoulder with 2100 ft lbs of energy and then exits, or a bullet that hits the front shoulder with 2500 ft lbs of energy but, doesn't penetrate to the far shoulder, thus, that shoulder gets hit with 0 ft lbs? The energy transfers during the full penetration event. The first bullet will hit the front shoulder at 2500, the first lung at 2400, the heart at 2300 the second lung at 2200. The second bullet hits the front shoulder at 2500, the first lung at 1750, the heart at 1000, the second lung at 250, and then pretty much bounces harmlessly off the rear shoulder. If the bullet is slowing down to the point that it fails to penetrate, it's going to transfer less and less and less energy as it slows. The first animal's various organs are hit by a cumulative energy transfer of 11,500 ft lbs. The second gets hit by 5500.[/quote]
What your saying is absurd... With two EVEN weighted bullits you could have exactly what you are saying. Im not sure what condition I would ever want this in unless I needed to shoot a tank but here we go... Keep in mind, both shots are the same, and they travel the same path...
We will start with bullet 1. Bullet 1 has an initial impact of 2500#'s. It is a lead tipped bullet.
Bullet 2 has the same specs as #1, except it is not meant to expand. It is meant for strictly penetration, so... its structure will stay composed at all times...
Bullet 1 lodges in the opposite shoulder. Bullet 2 passes through cleanly.
Upon exit, Bullet 1 left with 2000#'s of energy. Impressive on penetration yes.
Which Bullet would you rather hit a deer with??? The one that leaves a bullet sized hole in the deer but only expends 500#'s as it travels through the deer, or the one that smacks it hard, expending all of its energy inside of the deer tearing the inside apart.
You know which one did more damage!
What you are saying above is true yes and can happen. But in equal circumstance, the bullet that is not passing through is OBVIOUSLY doing more damage
You're arguing a completely different point. I'm noting that it is absurd to say that because a bullet entered at 2500 ft lbs and exited at 2000 ft lbs, that it "only expended 500 ft lbs as it traveled through the deer." That's pure unadulterated BS. It has lost 500 ft lbs on its way through, but, it is expending energy during every microsecond of its travel through the deer. It's simply ridiculous to say that a deer hit in the front should by 2500 ft lbs, and in the rear shoulder by 2000 ft lbs has had less energy "expended in the deer" than one that gets hit in the front shoulder by 2500 ft lbs and 0 ft lbs in the rear shoulder because the bullet "expended all its energy inside the animal" and didn't fully penetrate. A hunting bullet that fully penetrates, and carries its KE all the way through the deer is going to cause more permanent and temporary cavitation on its way through than a bullet that stops half way through. Your apples to oranges comparison using the FMJ bullet kind of proves the point that its not the KE that kills, since the FMJ has the same amount of KE as the soft point. What kills is the damage caused on the way through, which is the result of the interaction between the bullet and the tissue. Try carrying your hypothesis in the other direction, using a 100 gr bullet of light construction designed for varmints, versus a 100 grain bullet designed for deer that fully penetrates. Both enter with the same KE. The varmint bullet expends all of its energy, but, doesn't penetrate very far. The bullet designed for deer holds together and fully penetrates, causing damage all the way through the deer. Which would you rather have?
Once again, the idea of "transferring all the energy inside the deer" i.e. by not fully penetrating, is ridiculous. There is far more energy transferred during a full penetration event.
