Pyrodex used to produce a "Cartridge" grade of their powder. This CAN be used in an Old Army (desperate times, desperate measures) but it's very coarse and doesn't compact well. Don't know if it's still on the market or not, but I think it'd be likely to do a good job as a launching load.
Hot glue plugs, eh? Yeah, I can see how those would blow out instead of blow up.
