Re: Bullet "energy" matters!
I'm not saying to dismiss energy all together. You are correct with your statement but i think energy is a very tricky term. But without the right amount of velocity then for the bullet to expand then energy won't happen. A bullet that hits its target has energy carried with it but it is useless if it doesnt expand.
You obviously haven't studied a lot of wound channels. A 12-gauge slug will tear a hole through an animal that is slightly larger than the slug. That is penetration damage. Expect a similar wound channel from a .375 H&H magnum at 400-500 yards. A 7-mm Rem magnum with an expanding bullet fired into a deer's chest at close range will often leave an exit-wound 6-8" across. That exit wound does not mean the bullet expanded to the size of a cannonball. It means the hydrostatic shock caused by the energy of the projectile was enough to liquify tissue. Likewise, I have shot woodchucks in the head with a high-speed bullet & had the shockwave split open the belly & gut the animal. Once again, this does not mean the bullet deflected & cut open the belly, it means the shock was enough to blow out the critter's guts. That shockwave is purely a result of the energy of the projectile. Energy levels undoubtedly matter. If I shoot a deer in the chest with my .25-06 inside 150 yards, I expect the lungs to be liquified — purely a result of the rapid energy transfer.
What I have never seen is a formula that correlates energy of a projectile directly into "kill-power". There are simply too many variables. A .22-.250 has lots of energy due to its speed but little kill-power on large game because of the light bullets and limited penetration. Fragile bullets transfer energy faster than solids but don't penetrate as well. Obviously, energy is not everything, but dismissing "energy" is silly.
