As stated on this forum before, grew up around and old, old man who used C&B revolvers, (in real life.) He always greased his chambers after loading. Said it cut down on fouling and ring fires. It did. Followed his advice and after firing hundreds of rounds from C&B revolvers, never had a ring fire. Said bear grease was best, but growing up in rural Oklahoma, it was a little difficult to come by. Found a product that claimed to be as good, GREASE BALL. Came in a tan colored tube with brown 'Old West' style lettering. Haven't seen it or been able to find it in Years, though. Even as a Cop in an Okla. University town, knew a OHP (Okla. Highway Patrol Officer, that carried a .36 cal. Navy (of all things) for his back up pistol. He used Vaseline to grease the front of his chambers. Perhaps, lubing the front of your chambers is 'messy' but as far as I've seen over the years and hundreds of rounds through a C&B revolver, it does work, at least for me and a few other 'Old Timers.'
