The 308 will do anything the 30-06 will do and with a shorter action. However, EVERYONE carries 30-06 shells and different variations, it's just a very common round to carry. I actually have both and love my 308 for it's accuracy, but love my 30-06 because I can go anywhere with it and it will bring down anything and you can guarantee ammo anywhere you go. Then again, I brought down my Canadian buck with my 308 at 150 yards(The buck weighed 300 lbs) with a single shot. I'd go 30-06, it's just so versatile and ammo is soooooo easy to find. Just my 2 cents!
