Well, I probably aint gonna be much help here but I will tell you any way.

The dead deer, elk or what ever will never know the differance between the two cartridges and likely neither will you.

The 30-06 will have about a 100 fps advantage over the 308 in any given factory loaded bullet weight. That doesn't ammount to crap in the real world of hunting.

A 308 will fire a 180 grain bullet at about 2625 fps the 30-06 will do about 2700 fps.

Sight them both in to be zeroed at 200 yards and you the 30-06 only has a half inch advantage at 300 yards and only a 2 inch advantage at 400 yards and a hundred foot pounds more energy.


Honestly, my decision would be based on if I wanted a long or short action.
