This may work for you, may not. It's been very accurate for me in 3 different rifles. A savage M11, Rem 788, and G3. 44 gr IMR 4064, Speer 150 Hot Core, PRVI brass, Rem 9 1/2 primer. You'll have to set a COL appropriate for your rifle, as mine are/were set a little on the long side of Speer book. This load is on the mild side, you could tweak it upwards on the charge if you desire more velocity, it held accuracy for me when I worked it up to max, but the wife doesn't like the recoil and blast at full power and our deer ranges are relatively short so I worked it back down.
IMHO Varget, IMR 4064, R15 are all in the sweet spot for .308 with 150-168 grain bullets, and keeping the bullet simple...cup and core...will hedge your bet towards better groups and easier load development.
