I think that one thing that you should remember is that when Jeff Cooper was younger the bullet were not as good as they are today. Lead cores with a thin jacket if you push them at magnum speeds they would blow up. So you went with larger cal or heavier bullets. My Great Uncle who was slightly older than Jeff Cooper love his 45-70 said my dads 30-06 would of been better with 220gr load than the 180gr he used for deer, and said my 7x57 was a popgun.
