What drove my curiosity was it seemed that the original poster had decided on a powder and primer and was then kinda looking for a rifle to fit. Which, perhaps, is as good a way as any. .
Well, almost. I had the rifle that was shooting easy 1 inch groups at 100yds with 70c off the shelf CoreLokt. (despite my serious lack of ability, cleaning inbetween rounds, slight flinch and too much adrenaline).
So I decided to reload to bring this to about 35c a round. Twice as much bang for the buck. The accuracy nuts seem to like Varget, and Varget seems to be very consistent in all temperatures, at least according to Hogdons manual. And all the other reloading books seemed to list Varget as a decent powder for the 308. Most had BR2 data, especially at SavageShooters.com.
So I was left choosing a bullet. In the end, thanks to this group, I picked up some Harnady A-Max 168, Matchkings in 168 and also some cheaper 168 Remington PSPCL.
I'll try to find the best 168gn combineation, then start varying weights and primers.
Thanks again to you all :-)
