I thought about perchlorate vs roll caps, but self preservation keeps me with the roll caps. I made a living as a lab technician in chemical plants, worked with lots of noxious stuff, never hurt, but hey, I'd like to keep that record. LOL! I do intend to make use of your vids and get into black powder production, got most of the hardware, just haven 't done it.
Thanks for the vids, good for the knowledge of those treading into the unknown. The black powder production vids will, once I get off my lazy duff and try it, be very helpful.
