I've loaded a boat load of .308s over the years and any moderate burning powder is going to be okay. The problem you are going to encounter is if you aren't careful, you'll waste a lot of time chasing that ultimate load when so many different ones are so darned accurate. I've used 4064, Varget, 748, 3031, and my favorite, H4895. Load a Sierra 168gr. MK and enough H4895 to drive it at 2500-2550 fps, and find out just how good your rifle will shoot!
