I don't think you have any comprehension of how much hunting experience somebody like Craig has, which has sometimes been dozens in one year alone--along with being alongside many hunting partners while they took various sizes of big game.
He also hasn't just hunted during the North American seasons, but has hunted year-round. He's probably personally killed over 1000 big game animals--and seen more than that taken by hunting partners.
Actually, if you'd read Craig's writing as much as you seem think you have, it would be apparent that he's a more of a .30-06 fan than a 7mm magnum fan.
But whatever.....
