Hi
I shoot a .44 Remington and a .36 colt with black powder only and clean them with hot soapy water in the kitchen sink. The revolvers are much more labour intensive to clean properly than my musketoon as you have all those chambers to clean as well and an amazing amount of gunk and bits of cap find their way into the frame and trigger group.
As for lube I use a mixture of beeswax and vegetable oil (no I'm not an eco-warrior, just cheap

) all dispensed from an old hand soap pump but one guy I know swears by Swarfega, says it cleans his gun as he shoots! :lol:
You’ll also need something to put the caps onto the nipples with, especially in the cold weather. I use a piece of bent copper microbore tube but you can buy dedicated cappers for a tenner or so.
A homemade wooden frame to hold the pistol upright whilst loading is a godsend but you can do it without.
Also my club doesn’t allow powder flasks due to safety concerns emrolleyes so I pre-measure each charge and put them in a 6ml glass screw top test tube (ebay).
Have fun
Dave
