Id drop the the 30-06. Its not going to have the range of the 270 and it doesnt have much more power than the 308. If you need a little more range take the 270 with you to the woods occasionally (I say occasionally because I have a BDL in 7mm rem mag and I rarely take it on fear of scratching it) and make the 308 your everyday beater. Thats just my opinion though...
