Anyone know what this powder is? “Smokeless Black Powder” seems a bit of a stretch.

They use to manufacture and maybe still do for some special purposes what what was call bulk smokeless that had black powder burn rate and pressures. There are black powder substitutes that are used in muzzle loading arms that are basically the same burning rate of black but are really more smokeless.

Actually there are several types of black powder substitutes that are called "smokeless black powder", they have all the characteristics of black powder but they smoke a good deal less and leave less residue in the barrel upon firing. One of the earliest attempts of this was Pyrodex,which does smoke slightly less and produces a smaller amount(not much difference)of residue. However, there have been great advances made since then, one of the names, just off the top of my head, is Clear shot(I think)and others are Black Thorn 209, triple seven and at least one more whose name I forget.

I prefer Pyrodex because I am used to it and it doesn't leave me covered in goo the way real black powder does and is easier to get, black powder is limited in production, however the new substitutes are a lot cleaner. Be that as it may, Pyrodex is the number one substitute used by most muzzle loader shooters.
