I actually have the gun in my possession. It is an Italian made Investarms .58, just checked.From the pictuire it appears to have been an OTC gun? Do you recall the brand?

Odd! the Italians usually make good stuff - at least they do today! Years ago not so much, I believe! These days I understand they do some serious proofing before a gun goes on the market! I have heard of, but have no experience with Investarms.I actually have the gun in my possession. It is an Italian made Investarms .58, just checked.

Ouch!!!Discuss
Strange things happen. When I was in high school, my dad taught vocational agriculture and shop. One of the boys brought in his double barreled shotgun, which had one barrel burst up close to the muzzle, maybe an inch back. I recall a flap of metal was peeled back. He had tripped and fallen while out hunting, and got a dirt plug in the muzzle during the fall. The barrel blew when he took his next shot. This was a hammerless breechloader with smokeless ammo, which we don't normally discuss on this board, but we're talking about burst barrels. It didn't take much of an obstruction to result in a rupture.
Dad helped him cut off and square up the barrels as a shop project.

Would someone please explain the physics behind the theory that an air gap creates a “pipe bomb” To my knowledge pipe bombs are usually stuffed full (no aireap) and in the bp rifle the potassium nitrate is producing all the oxygen the sulphur and charcoal need to burn. So pleas explain how a little extra air causes such a violent rise in pressure so as to damage a barrel. As far as I’m concerned the bore obstruction theory is pure BS unless there is another projectile loaded behind it. No anecdotes here please, just pure physics.Was gonna post a link to this in the previous 10 page post on how to remove a minie ball from a 61 Springfield but I see it has been locked. Someone suggested shooting it out from where it was stuck part way down the barrel . They referenced having personally done it numerous times with no problem. This is an example of why Not to take that chance .
I can tell you for a FACT that there was one ball and it was short started and that was the end result. Not to be rude here, but you sound like someone who if they don't see it for themselves, it didn't happen. It did. No bs.W

I always kinda thought that a BP ML was in a sense an inverted bottle rocket. The way the powder propels the ball/bullet/slug is basically the same.Not a scientist or engineer so I really can't do that . Pipe bomb was a slight exaggeration on my part , but maybe not by much . Black powder needs to be compressed to be a propellant so that it burns progressively going down the barrel . Left loose in the barrel due to a ball not being seated it detonates rather than burning . The ball will come out of the barrel ahead of the gas but the huge pressure spike created by the gap Can burst or bulge the barrel . Not guaranteed to do either but it can and does do it . My point is , don't take the chance and end up being the one that it does burst on .
We don't know if a ball was loaded then a second ball short started. We don't know if it was snow or mud.
You are right. I haven't read everything. I'm anxious to go to sleep. It's getting late here.Then you posted without reading the thread . Who is this We you are referring to ? I know it was neither because I read where the OP stated there was only one ball and no other obstruction . He was a witness , I have no reason to think he lied .

I am the "witness" being referred to. I have this posted on other forum sites as well. I've had much in the way of knee jerk response insinuating everything from made it up for click bait to outright lying. Sheessshhh!You are right. I haven't read everything. I'm anxious to go to sleep. It's getting late here.
Of course I am not implying the witness is lying.
I am implying, I guess we will never know exactly what caused the failure.
My apologies if I offended any one.
