GOB.. I have only used a few of the new powders.. Pyrodex seems to be less corrosive than black. Triple 7 is defininitely less corrosive I have tried a couple other substitute powdwers and found them to be not as easy to use as the two mentioned..Shockeys was one that comes to mind. What many do not understand is that 777 is actually a type of smokeless powder and in MLs creates a crud ring that is not easy to get out..Pryodex not so much..Velocities are soehwat higher usually with 777. Pyrodex about the same. But here is the real rub. the subs are EXPENSIVE compared to black and other powders that can be used in cartridges. There are quite a few smokeless powders that are easy powders in BPCR..You already know of trailboss and then there is AA 5744 Many others too VV has some powders that can be used. And there is another thing..Many people now have never used Black powder or anything resembling it..so they do not know what to do after shooting the corrosive powders. Heck most don't even know how to clean a rifle using smokeless. Heck I have MLs of all kinds but since there is no actual ML seasons as such here in Wy..I don't hunt with one. Some do though..I do use the newer inlines though..as does my daughter and family as well as many friends in Md and Delaware. Most shoot the Savage Smokeless powder MLs. I know many don't consider them worthy ML rifles.. but I can say with certainty..Ol Dan'l or Davy or Jim Bridger would have used 'em with great happiness. If loading for other people commercially I personally would not load Black or Subs. If they request them...let 'em load the darn things themselves. Loading BPCR loads for accuracy takes as much testing as smokeless to find a good shooting load. In some cases...even more!
