[QUOTE="RockyMtnMT, post: 1235315, member: 7999"] I am not doing a good jog of explaining the energy. It is not the energy that does the damage. The energy is an arbitrary number. It is the form of the bullet that causes the terminal performance. Having a bullet remain in an animal and leave all of it's energy in the animal is not some sort of a bonus or ideal outcome. In the case of pointed bullets we need the force of the impact to cause the deformation of the bullet necessary to cause permanent displacement of the soft tissue. So as JE said, a pointed bullet that stays pointed will not do enough damage to efficiently/quickly kill. As well as a bullet that comes apart and can not penetrate deeply enough. With bullets we need them to tear the soft tissue to cause traumatic bleeding for quick kills. So on impact we rely on the force to change the shape of the projectile into a shape that causes the permanent wound needed to bleed the animal out quickly. A bullet that comes apart on impact has the potential to do great damage laterally as well as the potential to not travel very far into the animal. Leaving the possibility for a poor result. A bullet that deforms into the classic mushroom shape and retains enough weight to keep momentum and penetrate deeply will have more consistent results. The rounded shape of the mushroom allows for some flow of the soft tissue around the bullet and back into place as the bullet passes through the soft tissue. Compare this with a projectile that becomes flat on the frontal area, retains enough mass to keep momentum and penetrate as far as possible through the soft tissue of the vital organs. The flat frontal area will displace the soft tissue in a perpendicular direction to the direction of travel. This perpendicular displacement is more permanent than the rounded mushroom shape leaving a larger dia permanent wound to bleed. As a projectile slows down inside of an animal the displacement of soft tissue becomes less narrowing the size of the permanent wound channel and lessening the amount of bleeding caused. So having a bullet remain inside of an animal does not help in causing the trauma needed for quick killing. Bullets do not have the ability to know how far they have penetrated and then magically open up like a time bomb. Leaving the "energy" of a bullet inside the animal has no merit based in physics.
