With extensive experience (25+ years) loading 380, 9mm, 38 Special, 357 Mag, 40 S&W, 10mm, 44 Special, 44 Mag, 45 Auto, and 45 Colt trying loads of powders from the old standby’s to newer stuff.
I now run it all with just two powders. For cast and jacketed both. Ramshot True Blue and Accurate No. 9.
If ever limited to just one powder, it would be True Blue!
