Through a combination of case improvements (the .308 has the same shoulder diameter as the .30-06 AI) and powder improvements they succeeded. But there are many who are ignorant of history. The .308 has acceptable velocity for a non-magnum hunting round. Where it sometime falls down is twist rate and as a result availability of heavy hunting loads.
