I'm going to be contrary. I handload so I can select the optimum powder for whatever I'm shooting.
You might be able to load a pistol r shotgun powder into rifle reduced loads,
But human beings being fallible,a double charge will easily hide inside the case.
Those wreck guns and hurt people.
I suggest yo list the cartrides you want to load for,and maybe two or three powders will cover them pretty well.
Now,this IS from memory from a few years back,but in the Hogdon Reloader Annual,that looks like a magazine,I recall (IIRC) listed,tested Varget loads from 17 Mach IV to 45-70 trapdoor. I tried some in a Rolling Block 40-70 Sharps Straight/405 Win and it worked...not great,some unburned powder,but it went bang and put a hole in the target.
Its pretty versatile..but I would not load my handguns with it.
If I had HP 38 or HS 6, Unique or 2400, Varget and 4350 or RE 19,I suppose I could get by.
I could be a smart alec and say FFFG Black powder.
