I all boils down to velocity and the range you can humanly harvest a large animal like an elk, assuming you and our rifle are accurate enough to place the bullet where it belongs. (see above)
A 308 will launch a 165 gr bullet at about 2700 fps (2670 ft/lbs), whereas a 300 WBY will launch the same bullet at about 3300 fps (3989 ft/lbs). Point being the terminal effect on the game by the 300 WBY is the same at approx. 275 yds as the 308 at the muzzle! So if you are aware of the 'range' limitations of the 308 it can humanly harvest an elk.
I personally would limit my shot at an elk to 300 yds or less with a 308, and with a 300 WBY to 550 yds or less.
To address your question about the 30-06. The same bullet could be launched at about 150 to 200 fps faster than the 308. This is not a significant difference. You would gain about 50 to 75 more yards on your comparative effective range. Is this worth going to the 06? It depends on the range you anticipate on your hunt. But me, I think I would stay with the 308 if you shoot it well!
Hope this helped.
