I guess about the only thing I can really add into this post would be that the new breed of super magnums only really came into there own in the early 1980's. Which makes me think what would the guides and hunters in the know before then say in there opinion was or isthe best caliber(s). I'm quite sure that the tens if not hundereds of millions of big game animals killed in the last century and a half, if asked would say that bigger, faster, flatter, louder,harder hitting and better exspanding. Matters not to us,where still dead either way.
