Not sure what point you're trying to make anymore but between what the ER doctors have to say about real world experience, NOT about inanimate targets, and this from your article, you're just beating a dead horse.

A badly torn up one if shot with an AR-!5.

Faster bullets are also better for terminal performance. One of the important aspects of terminal performance is the transfer of energy. If a bullet is traveling at a faster speed, it will either penetrate deeper, expand better, or both.

Energy at the target, which is considered critical to terminal performance, is enhanced when a bullet is traveling at a higher speed. We’ll use another sports analogy to make this point: think of a linebacker traveling at 6 mph, which is a typical jogging speed. If he hits you, it’s going to hurt. However, if the same linebacker hits you at a sprinting speed of 14 miles per hour, it’s really going to hurt.
