I load and Shoot my New Model 3s and Top-Break "DA"s which are .44 Russian, and I load Black Powder Cartridges for them.
I have reviewed this a few times, but basically I make and use a simple Beeswax Disc between Powder and Bullet, and I can shoot for ever with no fouling or Cylinder Binding, and if I forget to clean, nothing happens.
Clean up is easy, merely warm Soapy Water and a Nylon Bore Brush, dip the Bore Brush, clean Barrel Bore, clean Cylinder Bores...no need to soak the entire Revolver, no need to get Water in to it's mechanism...just dip and use the Nylon Bore Brush over the Kitchen Sink.
Initial dry for Barrel and Cylinder via simple wad of Kleenex or Toilet Paper, puch through with a Wooden Dowel.
Dry the Revolver with a Hand Held Hair Drier, laying it on a folded Towel, and propping up the Hair Drier...till it is warm enough to be thoroughly dry every where.
Nothing in shooting Black Powder has ever once gotten in to any internals for me, on any Black Powder Revolver...Cap & Ball or Metallic Cartridge.
Right Lube approach, all stays clean, and the most one ever sees is a tiny hint of wispy light grey film maybe at the Muzzle end, but not enough to be noticeable casually unless one is looking for it.
Hands stay clean, Revolver stays clean.
Super easy to do, works perfectly.
"Swiss" Powder...
Never "Goex"
