Hydrostatic shock is, as I understand it, the shockwave in your body (which is mostly water) from the impact of a bullet. A great deal of energy is required to create this, hence it's usually only seen in rifle rounds.
Hydrostatic shock is, as I understand it, basically the same thing as when a small meteor hits the earth and leaves a big crater. The more mass and the more velocity your projectile has, the more energy it creates when it hits something.
It's why a shot from a .30-06 FMJ round is more devastaing than a .357 magnum round, even though the .357 is a larger (and in some loadings, heavier) projectile. The .30-06 is going almost twice as fast.
Am I correct in this? That's my question. I've been trying to explain to someone that knows nothing about ballistics why rifle rounds do so much damage, as opposed to just leaving a (say) .30 caliber hole in one side and out the other. IF that were all they did, after all, .45ACP would be MUCH more lethal, as it'd leave a much bigger hole clean through. It's also why even FMJ rounds can leave a bigger exit wound than an entry wound, if they're going fast enough.
It's all about the kinetic energy, right? Meteor hitting the earth?
