I would get the IMR 4064 that is in stock at Third Generation Shooter supply, they have a ton of it. I've used IMR 4064 with 168 an 175 in .308 with very good results. It's a great powder. Accurate will work as well.
I must say that I have 2 Savage .308's and both of them shoot very well with pretty much every powder I've tried that has load data for .308.
