One thing I try to do when I clean a revolver is that I try and use a larger bore brush than what it says. For instance I use a .40 brush for my .357's. Works great and gets out everything like lead and fouling. On the other hand, I used to take a copper scouring pad, pull off a long piece of what looks like a single strand and then wrap that around the brush. That works just as good. Get a decent brush, scrub it good with Hoppes 9 and then clean it out and it should clean up.
