Go with the 30-06. The 30-06 is more versatile in bullet weights. They both have tons of factory ammo the 308 has a few more that are cheaper, but they are military full metal jackets and are worthless except for plincking around. There is also alot to be gained from handloading the 06 and not as much w/ the 308. I think that the advantages that the 06 has are more practicle than those of the 308.
