Other items would be a powder flask (I like the tin ones for pistols rather than the horns), powder measure, cleaning accessories like toothbrush, jag, and bore brush, small set of the appropriate screwdrivers, extra nipples and nipple wrench, and a bag or container to keep it all in. For the grease I use Crisco shortening as it works just as well and is much cheaper. I keep all my blackpowder cleaning supplies in a cleaning bucket which I fill with hot soapy water for cleaning. Hot water works as well as any cleaning product and again is cheaper and easily acquired. Lightly oil all metal parts afterward and that should be it.
I wish I would have bought a .36 caliber or smaller rather than the .44 as the appropriate size buckshot works and is once again cheaper.
also too u should get a bullet mold cuz that was the most important thing when i used to have my black powder revolver
also too u might wanna learn how to make black powder from scratch cuz its way cheaper to do it like that but the only problem is that pure homemade black powder is more corrosive to the chambers than pyrodex powder
