If you can't find varget, imr 4064 will also shine in 308. So will BL-C2 and Accurate 2460... at least they do in mine.
Second for Varget and BLC(2)- I have also had very good accuracy (and deer on the ground) with 748, 760, and IMR 3031. 760 is on the slow end for .308 Win, but has been very accurate in all my my .308s. It also gives an impressive fireball from a short barrel!
