45.0 gr Varget under a 155 A-Max seated to 2.810 gives me an average of 2850fps with my 26" 10-twist barrel (factory Savage barrel) and well under 1/2MOA. I use WLR Primers and Winchester brass and use the Lee Collet dies to neck size only and then bump with the FL die every 6-7 firings as needed. Shoots great.

FWIW with Varget and the 308 you will find the data for max load varies between manuals, but Hodgdon lists 47.0 as a max IIRC and 45.0 gives me zero pressure signs.

RL15 is another great powder for the 308 in that weight class of bullets.

Of course use at your own risk, and work up properly.
