Ok, whenever you go to clean your revolver after shooting, do you find "powder" I guess is what you would call it, on the outside of the cylinder? I have noticed some gathering and getting dark on the outside of my cylinder like where each round goes in. Most of the time I can get it off with some solvent, but there are 2 areas from where I didn't clean my revolver afterwards. Is it common for the powder to come out the sides like that when it is fired?
