The powder I use depends on the gun I am loading. I use GOEX ClearShot FFFg with a Maxiball in my .50 hawken (I still have 5 pounds of it, which will be all I'll ever need!!). I use 777 FFg in my .45 Hawken with a Maxiball. (See pic below)I use Pyrodex in two inlines I have, and Swiss FFg in both of my flintlocks. I still have several pounds of GOEX FFg and a couple of ancient cans of DuPont FFg, plus a can of Curtis & Harvey (Austin Powder Co.) Musket powder. Haven't used any of this since about 1975 or so!
