I may have some powder, Matt.Now you need 2F or 3F powder, caps, and .375 lead balls. You can choose between grease over the chamber mouths, or Wonder Wad felt wads over the powder. I use the wads as they do a better job and are less messy in my experience.
Cleanup with soap and hot water and then a liberal application of Ballistol. Enjoy some Blackie Collins YouTube videos.
