The reality is that I understand terminal ballistics quite well. "Energy", which I take to mean ft-lbs, is not a wounding mechanism and has no relevance in this discussion.
Tissue is destroyed by two wounding mechanisms. They are referred to as the permanent crush cavity and temporary stretch cavity. The tissue that the projectile physically touches that is permanently crushed is the permanent crush cavity and the tissue surrounding the projectile’s path that is temporarily stretched is the temporary stretch cavity.
The permanent cavity is the simply the "hole" left by the projectile and fragments as they pass through. The temporary stretch cavity is the space that is left as the tissue surrounding the bullets path is pushed aside.
Of course an easy example of how "energy" doesn't apply as it relates to bullets and wounding is that a 180gr solid non expanding bullet at 3,000fps has the exact same "energy" as a 180gr varmint bullet at 3,000fps, and yet ft-lbs of energy tells us nothing about how either will perform in animals.
Terminal ballistics is a known, measurable, varifiable and repeatable thing yet most seem to want to hang on to completely disproven ideas such as "ft-lbs of energy" and "knockdown power".
The wound channel of those bullets I mentioned is more than sufficient for deer, and in some cases rivel the wound channel of much larger cartridges and bullets.
