The powder could well be proprietary; however, with the cost of R&D for powder development I would be surprised if RST is the only market for the powder manufacturer. It may well be a powder that is no longer in production due to a more modern or cleaner version being marketed but neither of the two powders look like what I would envision as a shotgun powder.
