Thanks so much. Now we are getting to some of the interesting things that I was hoping the post would do, such as this:

"Whether we like to admit it or not, the primary purpose of military rifle bullets is to disrupt human tissue. Yet the effects of bullets on bodies - the characteristic tissue disruption patterns produced by various bullets - remains unclear even to many of those who design and produce bullets. Surgeons who are called upon to treat the damage bullets cause, with few exceptions, lack practical knowledge of bullet effects. Attempts to fill this information void with formulae, graphs, flawed experiments, invalid assumptions, and theories based on half-truth (or no truth at all) have only increased confusion. "

I will look up further things by this author. Chap Gleason
