I thought that the reason a .30-06 could shoot the heavier bullets was because most .30-06 barrels have a 1 turn in 10 inches rifling pitch whereas the most common rifling pitch for rifles chambered for .308 was 1 turn in 12 inches, though I'm sure custom barrels can be had in any rifling pitch for either caliber.
