For the first 25 years or so, I loaded with IMR4350 -- 57 gr for everyone but myself. For my rifle, it was 58.5 gr and the velocity was so close to 2900 that we'll just call it that. (2892) Accurate, killed well. But a guy buys other powders because . . . . . . well, there must be a reason.
I now really like H414. Not noticing any inordinate amount of black soot.
Accuracy is phenominal. I'm guessing that RL19 would also work well, but I haven't tried it . . . . YET! Couldn't get IMR4064 to shoot up to my standards. H4895 shoots good with 150's. So does IMR3031. For the 180 grainers, I like IMR4350, H414, and my new favourite is H4831 -- a case full = bug holes.
Love the old gal. Just an old battle horse.
