Drew, you could ask him if barrel fatigue since the manufacture of the gun at the potential flawed spot could cause this or is something additional, such as corrosion, required as well.

As I see it 1. Everyone who was present said that the sound of the round going off was significantly louder than the rest of the shots being fired. 2. The shell in question must have had a large load of a high energy powder such as Bullseye to blow the gun. It probably was purposely overloaded and not an accidental overload. I do not think that a double load of a powder such as Reddot would have caused the burst chamber. 3. The shooter said that he was firing factory ammo. He is credible. I do not think that anyone would be crazy enough to knowingly load or fire such a shell. In conclusion I feel the shell in question was purposely overloaded prior to the shooter obtaining the ammo.

....The discussion as to the primer (viz. the primer bulge happening as the headspace failed) seems fair. But, it does not account for the extractor imprint. Logic tells me that, if there was to be an imprint from the extractor (as there is), then it would have to have happened before headspace failed and before the chamber wall blew out. First, the extractor is not in the region that failed. Second, on the chamber wall blowing out the pressure (necessary to force the shell head into the extractor to cause the imprint) would drop off rapidly.
I think this was a hot reload that met up with a chamber with a very weak spot. I would consider a couple of things. First, I dont think a slight extractor imprint in the brass is more significant than the blown out brass on the opposite side, the shell looks to have distorted as the shape of the chamber was changing. And second, I do not believe the primer of the blown shell is flattened, to me meaning that at the point the shell was fired it was not over pressure or if over, not significantly. Its a mess, but I dont see a flattened primer cup or other signs like flattened manufacturer stamping on the head of the shell. Apparently, the load fired out of the barrel and there doesnt appear to have excessive thrust against the breech. It appears to have failed radially, and the extractor happened to be opposite the force that it took to peel the shell open. Only thoughts.

I don't know why it busted. Lots of good guesses here, but I'm waiting for Dr. Drew's experts to tell me what they find through a scientistic investigation!...Geo

A few observations. All of the chamber failures Ive had firsthand knowledge of were reloads from a progressive loader , all loaded by life long reloaders , theyve all been 20 or 16 gauge and they have all been in the right barrel. Im not sure what all this means but I have my suspicions.

But they were all loading low pressure loads.

Old Redd Foxx might have fun with your response-- "Thar she Blows"- fitting, as L. C. Smiths are often called "Elsies", are they not.

I believe the LCSCA gruppen does NOT allow members to advertise Smith guns for sale on their website-- Not sure about the Parker-istas, nor the Fox-ists either. Only LCSCA member I know personally is Jent Mitchell- a Virginia Gentleman indeed- Every yeaqr since 2005 he sends me one of their beautiful calendars, and e-mails me and is kind enough to invite me to some of the SC events in the Eastern seaboard area-- Maybe some day I'll do that--with a few of my L.C. Smith 12 bores--
I NEVER shoot reloads in any of my shotguns, regardless of gauge or make or type--I prefer RST, then AA- then Federal, in that order--RWTF

A couple of additional points for whatever contributing value they may have.
Ref: pressure. Someone on the 16ga forum in discussing this event stated: I had Tom Armburst test some Factory Herters 1oz #8s a couple years back Fps right around 1200 , psi right at 11500 .
And, also, again a 2 3/4 shell in a 2 9/16 chamber.
Regardless, glad no one was hurt. Sorry he lost his Smith.
