CZ,
I never said what you stated.
I'll make it clearer. People initiating lawsuits with the intent of be compensated over and above what is reasonable are scumbags. Just follow the money.

Let me quote it for you.
"There is a lot to be said for his character, as there are a lot of scumbags looking for the money trail."

Evidently, You have decided that a person seeking redress for horrendous injuries is a scum bag.

Let me know how well your "character" holds up for paying a mortgage when cheap shells blow your hand off.

I've been through this before. You can't eat your so called "character".

The fellow whose gun blew up should have the full expectation of all his medical bills being paid, any rehabilitation necessary to regain function, lost wages, and his choice of repair, replacement, or purchase.

If that makes him a scumbag, did you file a comp claim when you had your rebar incident? Were there OSHA required safety caps on the bars?

The guys out 5-6 grand minimum, and everyone in the firearms industry knows it.

Enough crapping in this thread for me.
Anything else please put it in a PM.

Barrels are not seamed. They are machined, drawn seamless tubing or drilled and machined stock. 'Cept in the Dark Ages of course.

Wonko;
You don't always have to try & Show off your "Superior Intelligence" by trying to show every on UP.
I well know that it has been many many years since a flat bar was rolled into a tube with weld seam down the side to form a gun barrel.
How-so-ever an internal flaw on the inside of a piece of steel can be drawn out in the forming. This in the trade is known as a "SEAM". There are any number of recorded instances where such seams have resulted in burst barrels. "IF" however this were the only cause a ring bulge would not be present, thus my mention of the possible combination of a barrel fault which was holding up until stressed by the obstructional pressure.
When you don't know what you are talking about its always better to ask Questions than just go Belittling Everyone.

Re barrels and seams . . . since we're getting technical, one could say--accurately--that all monoblock barrels (as in Berettas) have seams, as do all sleeved barrels. That's not where the burst occurred in this case, but it certainly puts to rest the contention that barrels aren't seamed.

One last question of you guys (2-piper, Drew, et. al.) better versed in metallurgy:

If you look at the first picture and focus on the bottom tube, you'll see the burst drove a strap of barrel wall (approx. 1-1/2" in length) directly upward and into contact with the top barrel. That strap was formed when the barrel wall rent in two places, exactly along the welds?/brazings? that attached the side ribs. That's why the side-ribs are bent all helter-skelter as they were directly over where the barrel let go.

My question is: Could the heat of however those side-ribs are attached at the factory have stressed or weakened the parent (tube) material making it more susceptible to failing there? The two ruptures are exactly along those lines. These seam-appearing tears are what I think Bill Shodlatz was referring to in his post earlier in the thread.

Any thoughts?

I would think it would easily be possible to have a heat affected zone, or some potential damage to the barrels in that area. I would also suspect that the maker would be well aware of what's happening and might use heat treating options to address it. On appearances, if a ring bulge were to let go, there might be some advantage to directing the majority of force at another part of the gun rather than randomly.

I'd still overall be curious if the lower barrel mishap could cause an upper barrel obstruction. Or, if this is a near simultaneous double obstruction.

Rob;
I am not familiar enough with this model shotgun to say for certain just what alloy beretta used to attach the side ribs. I would find it extremely unlikely that an alloy was used which would create a heat problem. A modern alloy steel would have enough strength even in its totally annealed condition not to burst in a normal shotgun barrel.
What could well have occurred rather than an internal seam in the barrel is it could have been cut into creating a weak place in striking up the barrels after the ribs were attached.
This could have even withstood finial proof & not let go until stretched beyond their ultimate tensile strength due to the ring bulge. The combination of the bulge along with the longitudinal split says to me that two factors were involved. In fact the lower barrel may have only bulged similar to the top barrel had the 2nd factor not been present.
That's my take for whatever it's worth, I understand Wonko will try to make me look like some kind of Idiot, but I'm used to his rants & could care less. I can't really recall him ever adding anything truly useful to this board, always just "Putdowns"

While I will defer to the metallurgical experts on this site, I'd have a hard time accepting that the factory used a process to attach the ribs which would have so overheated the barrel steel as to weaken it. Seems to me to be too likely to cause problems and would therefore be rejected by a prudent factory.

IMHO, the most likely working theory seems to me to be (a) an obstruction in the lower barrel causing a burst, (b) a near-simultaneous discharge of the upper barrel, either as a result of (I) a flaw in the trigger or (II) the shooter involuntarily pulling the trigger (again if a ST gun, or the 2nd trigger if a DT gun) in the middle of all the other hell breaking loose, (c) either (I) a part of the lower barrel slamming into the upper as the lower disassembled itself, causing enough of a deformation (possibly elastic rather than plastic) in the upper to act as an obstruction such that the ring bulge was created when shot #2 came along, or (II) a second, smaller obstruction waiting in the upper for that shot #2 to come down the tube, creating the ring bulge.

(c)(I) would seem more likely if there were marks of some sort on the upper barrel's exterior, the existence of which I can't suss out one way or the other from the photos.

(c)(II) would require something extremely unlikely to have happened, i.e., a bad batch of base wads/shells such that multiple rounds in the same box left obstructions behind. It's (relatively) rare enough to have one bad shell, but to have 2 in close proximity has to be really rare. I could see this happening if the shells were reloads, but if they were factory loads then all the red lights should be flashing about this over at Federal.

Perhaps your friend has either the box from the shells, the receipt for the shells or bought them with his card. In that event, the manufacturer (in cooperation with the retailer) might be able to track the shells' manufacturing lot and pull them.
