30-06 is a 7.62x63mm.
308 is a 7.62x51mm.
so if the original parent cartridge for the two Savage cartridges was the 30-06, which were the parent cartridges for the 308, then a person could make the 308 from 30-06 cases.
There isn't much difference between the 2 cartridges as in dimensions on the cases but jeeez I don't think I would or could be bothered in mucking around resizing a 30/06 down to .308 considering the 30/06 will handle the heavier 165gn - 220gn projectiles better than the .308.
Going on the performances of my 30/06AI on previously mentioned on donkeys, horses, pigs, goats,deer and dogs I'll stay with the 30/06.
In standard form there's really not much difference in performance between the .270, .308 or 30/06 just what you can stand recoil wise and what your pocket likes it's just that the 30/06 can handle the heavier pills better which also gives me a better choice of projectiles for use on bigger game.
This is a thread which will have a lot of agree's to disagree's in it and can be argued like GM vs Ford or Sako vs Remington vs Winchester vs Ruger etc.
To me the 30/06 is the stepping stone from .270,.308 class rifle to the bigger .30's and beyond.
