I don't know much about ballistics but can anyone explain this or share their thoughts?
Follow the link and read to your hearts content, he covers it all. And there is really little difference between the calibers you've listed when it comes to terminal ballistics, oftentime's, ME's even have difficulty distinguishing the difference at autopsy! DocGKR is pretty much the
authority on the subject.
