So i got some BP revolvers from a friend's estate. All uberti. A pair of walker colts from 2021 and a 1861 Navy from the 1960's if i am reading the date code right. I found pyrodex and ISO in his BP supplies. He was a civil war rein-actor 
The walkers were put away without a proper cleaning. Saw some rust in the cylinders. After some play i was able to get the barrell and cylinder out. Barrell is in good shape. Still have to acquire a nipple wrench to clean the cylinders.
So some pre-emptive questions for the group depending on how bad this gets.
1. I assume PB blaster is safe to use on BP revolvers? Loosen screws and get the rust. Scrubbing with either 0000 steel wool or brass brushes on the tough spots in the cylinder. Then follow up with normal BP cleaning process. Missing anything?
2. I have a couple of replacement cylinders, unknown manufacture or date. The label says they need to be taken to a gunsmith for fitting. True?
3. Anyone use a 45 Colt conversion cylinder? Kinda interested in some fat and slow projectiles. Probably use with black powder and not smokeless for those as well.
