Question Ball Size

A shaved ring doesn't guarantee a good seal. I have one that shaves a ring but it will chainfire every time if I don't use a wad or lube. FWIW I've tried to make it chain from the nipples and can't do it.
Your mention of that gun is one reason why I'm no longer confident in claiming that chainfires don't happen from the front, or that grease over the ball doesn't prevent them. Yet I have to wonder what it is about that gun that causes the problem.

I never measured the chambers. They've got be pretty round at the mouth to cut a ring but they must get wonky. All of them will chain. Not always all at once but sometimes they do.

“…All of them will chain…” I am unsure, are you speaking of the chambers in that cylinder or all c&b cylinders in general?

That one. I've ran experiments on others without lube, wads or caps and none of them chained.
 
I'm gradually forming a theory that a loose cap forms a reflective "umbrella"
under whose edges the flame finds its way to ignite the primer compound.

That might be one way to explain why no cap/primer at all rarely chains.

I don't think so. I was pinch fitting #11 caps on it.
 
If you pinch fit, that means the cap has two opposing sides standing
"more clear" of the nipple barrel than the two pinched sides.

Otherwise nothing else I can think of makes sense ... when the ball is
a tight/shaved fit in the mouth and also slathered in sealant grease.

`Tis a puzzlement
 
Chain Fire worries are over done. I find it's really hard to get a BP revolver to chain fire unless it has some sort of internal defect - like tool chatter in the chambers.

Even when it happens, it doesn't hurt the gun, nor will it hurt you as long as you keep your fingers and body away from the front of the cylinder.

I like shooting lube under ball for best accuracy.
I'll load powder, wool felt wad, lube, and ball. That way the lube goes down the barrel vs all of your hands / the outside of the gun.

However, it's a tedious loading procedure. While I might start that way, I'll switch to lube over ball and then alternate with no lube at all.

It won't chain if I use lube or a wad. If I leave those off it chains.

This is true. The only ball that has any real force behind it is the one that goes down the bore. The rest just go a few yards.

That is my view, in general. There do seem to be exceptions, though, as Hawg demonstrates.
 
Lube over the ball is under-rated. It will keep the barrel so clean, about two patches will completely clean it. Don't mess with smearing greasy kid's stuff over the chamber, make "lube pills". Or...you may already know that. What lube, wads, and rings of lead have to do with chain fires, I don't know. But if you want to reduce fouling by about 90%...yeah...."lube pills"!!!!

I'm conducting an experiment.

I have a black powder revolver loaded, capped, and put up safely.

I poured warm beeswax over the balls before putting it up. It's packed in a case alongside a dessicant pack.

It's been untouched for about four years now, except I inspected it for rust a couple times in that period.

Between now and next summer, I'll be taking it out and firing it. The bet I have going with myself is that all chambers will fire just fine.
 
Hawg is right, it will fire, as long as it was cleaned properly first, and it is capped with tight fitting caps. The idea that black powder will "absorb moisture from the air" is a myth for sure. It's left over cleaning solvents, oil, or soapy water that will kill the charge. Before loading my revolvers, I clean them again with denatured alcohol, and then give them at least a couple of hours to "dry out", or load them the next day.

If the pistol was loaded with lubed wads under the ball, it will contaminate the powder, but should not completely kill/deaden it. I have left revolvers loaded with wads under the ball for long periods of time, and it seemed to reduce the power by about 50%. Still fired though, but weak.

I'm sure that pouring melted bee's wax over the seated ball is very effective, but that sure is doing it the hard way. Try "lube pills" next time. :)
 
That's horse hockey. BP isn't hygroscopic until its been fired.
I didn't think so, but I don't know nearly as much about BP as I do smokeless.

I thought it was at least possible since Bill Hickock used to fire off his Navies every night before cleaning and reloading to ensure reliability, but am 90% sure the stuff should last indefinitely given its makeup.

Perhaps more for the target practice, or practicing a quick draw?

I don't think it's recorded anywhere that he fired them every day. I can't find any recorded evidence that he did. There are instances of people being killed from loaded rifle barrels and artillery shells that have been buried since the war.
