Black powder

[Mills]

RST does not make black powder loads. They make smokeless loads with pressures comparable to black powder.

I’ve not loaded BP or a substitute in shells . I do however have an original 10 gauge percussion SxS I shoot some . Charlie’s correct Pyrodex is just as much trouble to clean as regular BP . In my 10 gauge I use granulated Hodgdons 777 . Pyrodex like BP has corrosive properties 777 does not . I’ve left ML deer rifles fired and uncleaned for a couple months (by accident) and when I went to clean them there was NO corrosion . With 777 all you need is tap water I prefer hot hot water but cold will do the job . You can take unburned 777 drip some water on it and it dissolves .
