I've used everything starting with Pyrodex, Black Canyon then going to Black Mag 3, then Clean Shot, then Clear Shot, then APP, Pinnacle, T7, and Black MZ. I'll use anything cheap in the shotgun like garage sale Pyrodex or APP but usually Black MZ due to it's low price. In cartridges: FFg Goex in 45-70, T7 in .357 mag (SASS shoots), Black MZ in 38SPL (SASS shoots). In the C&Bs (SASS shoots) Goex FFFg or Goex 5FA. in the 58cal rifled muskets/Hawkens FFg Goex. I always clean the day of shooting if at all possible. If not everything gets an oil coat.
