I like to load light for practice in all of my rifles. In the 308, anything that pushes 150's to 2300-2400 fps at the muzzle makes a pleasant load to shoot. Powders which do this very well include 4198 (29 grains or so) RL7, (30 gr) and 3031 (33 gr). I would expect 35 of varget would be pretty good. All of these shoot well under moa in my Model 70. GD
