About 10 years ago I bought a can of powder at a gun show, it was called Black Mag Powder, it was a black powder subistute, It loaded the same as black powder, by volume. It left almost no residue was supposed to be totally non-corrosive and non-ariscopic (not sure about that spelling but it means it does not absorb moisture from the air). and it even gave off a white smoke upon ignition. I only used it a few times in 45-70 cases and it worked fine. I also tested it on a piece of bare steel for a few weeks to see if it rusted or eroded the metal, it didn't. I've never seen it for sale and don't know if it's still made. any one have any experience or even heard of it.
