I said, or at least I thought I said, transferring energy is a byproduct. The bullet has energy when flying in the air. It uses that energy to expand a bullet . But the expansion mechanism and its expansion is based on velocity. The same bullet in different calibers and grain weights will have different amounts of energy but if they hit with similar velocities, they will have similar levels of expansion. Velocity is a better indicator of the expansion of a bullet than energy. You sound like you have taken a few engineering classes. I have too.No, energy isn't a by product. The only thing velocity does is describe lateral distance covered over time. Velocity does not cause the bullet to expand.
