A cylinder with a cap on it is entirely different than an uncapped cylinder.    I could imagine an the flash making it's way through an uncapped cylinder.   I just don't see it happening with a cap that stays intact on the nipple.

Got ya Richard. One additional cylinder going off can still be considered a chain fire then.

I can't. I've tried to make it happen short of packing the nipple full of powder and couldn't do it.

Hi, where a chainfire doesn't matter much:

Hi, not chainfire, but another firearm issue, detonation:

I have heard of smokeless powder squip loads doing this, but never have seen it occur in a BP revolver.

Interesting video. I have never seen detonation happen in person but have heard of it. He gives as good an explanation as anyone of what could cause it.

Saw on YouTube where someone intentionally loaded .445 s  into a 1860 Army without grease for the intentional purpose of provoking a chainfire.  This provocateur got it.  Maincharge and both ajacent chambers went.

Fun to see.

Just did a lot of shoot n. fired 7  different Colts.  All with only a drop of oil over the chambered ball.  All balls were round/conicals from the brass/steel molds.  Some balls were very easy to press into the chamber with no led shaved.

No chainfires.

I voted that I've never experienced a chainfire.

Here's my 2-cents worth on the matter.  I believe that chainfires occur from the cap end, not from the chamber mouth (presuming balls that fit properly and shave off a ring of lead).  I also doubt (but I can point to no research to back this up) that chainfires come from the flame passing down through a nipple where the cap has fallen off.

I do firmly believe that the flame from firing a chamber can and will pass up between the skirt of the cap and the nipple tube of an adjacent loosely-fitting cap, especially one that's been pinched into a oval to keep it on, and igniting the primer compound therein, thereby causing that cap to ignite and thereby fire its chamber.

That's an awful small hole for fire or hot gas to get down and how do you explain me being able to fully load six chambers and only cap one and never get a chain?
