As stated many times above, the 308 and 30-06 are both good deer guns. Whichever one you get will do a fine job. Pick out a gun you like that feels good, and don't look back. The 308 will have less recoil, but and good recoil pad will tame a 30-06 as well. I have both and hunt with both. Deer shot with either usually go straight down if I do my part. Get the one you like the best.
