H-4350 and 4831SC, they can about get it all done in a pinch here.
Two great powders for large capacity cartridges like 7mm Mag and the .30 Mags
I load H4831 in my .450 #2 NE 110grians. Boom!
I really like RL-17, H4350, H4831, H1000. I have quite a few other powders I use in a load or two, but those 4 just seem to always produce really good accuracy. Since I love the medium size cases the most, RL-17 is my most used powder, and it sure seems to have a bit of zing. Can't imagine not having a bunch of it stashed.
I'm just getting acquainted with R17. Big fan of R19 and R15.
