... But as far as answering the OP's question, I can't do it because I haven't used both to shoot elk with. How about you?
i've killed three elk using .308" bullets launched at .308 Win muzzle velocities. The elk don't know or care if a .308 Win fired it or not and it makes no difference to the validity of the results - If the same bullet is launched at the same velocity by two different cartridges (.308 Win or .30-06 in this case), the downrange ballistics are the same.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
