If the ball didn't fit the cylinder tight enough, I can see how the hot, high pressure gas could blow past a grease seal and the ball. A tight fitting ball is the most important safey issue from the front side. Grease, whether it's over or under the ball, just isn't much of an obstacle to hot gasses, though every little bit helps.

Is It a Uberti, Pietta?
The Uberti take a .380" ball, Pietta usually takes a .375"" ball...never did read what make yours is.

.451 ball should have a nice little lead ring then when press into the chamber.
Another mystery I guess...hopefully it won't happen again. I still can't get by that cap still bein' on there.

Rebel: let's remember the chain fire occurred on the third shot. I don't know how well moose snot holds up to cap and ball use but maybe it burned out/melted out.
In re-reading the original post I noticed the powder was pyrodex P, not black powder. That makes the chain firing all the more unusual.
Maybe just a freak event.
Question? When I used to lube over the balls I used crisco. Never had any trouble but on the other hand I never looked over the unfired chambers as I was shooting the gun. Maybe a better type of lube is needed for cap and ball guns, crisco mixed with something else. So... what do some of you use for lube? I use wads these days because the crisco was a mess but maybe a better lube would change my mind.

Being too lazy :redface: to mix anything up, I used to use white lithium grease. Applied it from a large plastic syringe (endless supply of used horse wormer paste tubes at my place). Never had a chainfire. (Did have tight fitting balls and caps). Your results may vary.
Stars&Bars,
I've been reading all the posts that you received on your problem and what Plink said about hot gasses getting past the ball started me thinking :hmm: about two things that I ran across over the years, two possibilities (that maybe others have encountered): I have several repro revolvers and none of them have perfectly round chambers--most are slightly oval with some being as much as .003" out of round. I also found on a few rare occasions in "store bought" stuff a ball very slightly smaller in diameter than the rest. Is it possible that this rare/random combination of an oval chamber and slightly undersize ball could set up a chain fire? A freak event like Crockett mentioned? We all know how much fire flies out between the cyl and barrel!
I measure the chambers in two directions; one on a radial line extending out from the center of the cylinder (spoke of a wheel) and the other at right angles to it. The radial dimension has always been the smaller dimension. Possibly from the metal stress-relieving itself across the outer arc of the cylinder at the chamber??? I don't know........
Don't know anything about the unfired cap, that's really a question mark.
Anyhow, for what it's worth.......
