In my experience with the 30-06, H4350, H4831SC, Staball 6.5, and Varget have been the best consistent powders from 150-200 gr bullets. That Staball 6.5 is an impressive powder if you can get your hands on it.Took the chopped tikka 30-06 out today for load testing. I was doing 3 shot ladders using 178gr ELDM and Super Performance powder… this looks like a good load. 2820 fps out of the 20” suppressed, below book max:
