.308 vs .30-'06 is Ford vs Chevy. Not worth arguing over. Get what works for you and your arsenal. The only ballistic difference between them is in the heavy 200 gr + bullets which the .308 just can't shoot as efficiently as the 30-06 can. Most all hunters I know who hunt 30-06 (including me) don't use 200 grain and heavier bullets. But, like I mentioned before, if you live in an area where current military calibers dissappear with the next Internet news headline, .308 will be one of them to go. 30-06 is almost always there, even as surplus and cheap at about $1.00/rd. My hunting round is only 55gr powder and a 180 ballistic tip. Poi/poa is dead on (for hunting purposes, not bullseye shooting) out to 325 yards.
Also, with short barrels in rifles, handloads are the best option using faster powders to reduce the muzzle blast. Hornady and other reduced recoil loads are great for short barrels too. Lots of options, but it's hard to beat any of the .30 caliber options out there (except .300AAC, it's not a hunting round imo).
