—saw article on that subject in one of the gun magazines some years ago-—if the 6m/m Lee-Navy had had the powder and case capacity (smaller) allowed by better powder, it would likely still be the standard military caliber world wide-—
I just finished reading Popenker and Williams' book "Assault Rifle," and they also mention the 6mm Lee Navy as being ahead of its time. The propellant technology and bullet designs were just not mature enough to keep the major powers from going to the .30 through 7.92 calibers even though many of the theorists of the time said that somewhere from 6-7mm was the answer.
