It's been years since I reloaded, I used IMR 3031 for my .308 / 30.06 rounds. There are alot of new powders out now, good luck in your search. Corrected..
I was a dyed in the wool Varget guy until this last round of shortage and the abysmal market shortages at any given time. I HIGHLY recommend the Shooters World S-062, it’s an equivalent to Varget that’s plentiful and IMHO I’m getting better more consist results.
