Greywolf - Varget is an outstanding powder for the .308 Win, so you're set there. Good velocity and good accuracy is the norm with that powder, I've been using it for years with my competition loads.
Don't be afraid to try different bullets, hovering around the 165 - 175 grain weight range, or even some 150 - 155's.
CCI and Federal match primers both work well.
Winchester brass requires a little prep work, but does a fine job. Lapua is excellent.
