Did you end up picking a caliber yet? Hahaha. Lots of votes. My vote would be for the 308 in a 165-175 grain all copper Barnes or a quality bonded bullet.
With the 308 you aren't giving up much power over the 30-06, but it is a decent bit less recoil.
I disagree with some opinions that a 30-06 is so much better suited to things like wildebeest, zebra, gemsbok, eland. Again, you aren't losing much by going to the 308. So anything people consider sufficient for 30-06 is essentially equally sufficient for 308.
Obviously opinions differ on this and anything caliber related, but these are mine.
