The .308 Win. case has shot 180 to 250 grain bullets with better accuracy than the .30-06. Yes, 250-gr. bullets in a .308 Win. case, but the throat has to be longer else one couldn't get enough powder in the case.

2150 fps with that 250-gr. Sierra match bullet in a 1:8 twist 28" barrel was a winner in the late 1980's. It got replaced with the 240 grain version.

Of course, the .30-06 case will shoot a given bullet out faster with the same peak pressure.

I've no idea which would better with a can, but that can may well degrade accuracy. I think you need a license to use one; costs $200 or something like that. And a dozen or so states don't allow them.
