If you plan to to use 165-168 gr (or 150 gr) and keep shots to say a max of 300 yards. Then a .308 win is near perfect. If you plan on shooting 180 gr (or 200 gr) than I would go with the .30-06.

Someone once explained the differance like this: The .308 is like getting ran over by a cement truck....while the .30-06 is like getting ran over by a FULL cement truck.....you'll never know the differance.

I went with the .308win. I figured if I am going to take .30-06 recoil may-as-well shoot a 7mm Mag and have a flatter trajectory.
