My standbys have been Unique, Trail Boss, 2400, and FFFg. The easiest to load is FFFg, just fill there’s and cram a bullet on top. If you want a fire ball for night/twilight shoots, this is THE load! Clean-up is a breeze with HOT soapy water too.
For those of you who don’t know, FFFg is a fine grade of Black Powder.
For lye last few years, I’ve only been loading Cowboy Action loads: 200gr cast RNFP on 6.5gr of Unique lit by a WLP. Magnum loads are 240gr Cast GCSWC over 18.0gr 2400 lit by a CCI LPM.
