As for terminal ballistics, it's a crap shoot...
The bullet exits the target, it's wasted energy, so pointless to have 'Super Duper' penetration.
Keep in mind how thick a man's torso is, anything that penetrates more than about 8" is pretty much wasted.
The idea of a bullet exiting the target, as opposed to remaining in the target, being "wasted energy" is one of the biggest ballistics fallacies on the internet. Energy, as determined by foot pounds of energy, is nothing more than a mathematical formula. This mathematical formula has never killed anything. What kills is massive tissue damage resulting in the cutting of blood vessels, resulting in a rapid loss of blood pressure leading to loss of consciousness and possibly death. Obviously, a bullet that provides complete penetration results in more tissue damage than a bullet that stops inside a body. In addition, a wound that includes both entry and exit hole promotes an increased amount of blood loss. IMHO, any shot that does not result in complete penetration is a failure.
