I have seen at least two videos of people trying to replicate a KB with the 20-12 thing and nether of the barrels blew, I am thinking it is a defect in the metal. Here is one with no failure. ETA:Here is a failure with an older 12 Ga. that blew closer to the muzzle like the Mossi 500 I still think it was a metal defect, a modern gun like a 500 shouldn't fail if a similar 870 like the first vid doesn't. Both videos are the same........... |

Quoted:
I've had wads stuck before. Air pressure from the upcoming shot charge just pops them out. This was something more. Maybe the full shot charge. No excuse for it in a pump IMO, you should be able to feel and observe a squib easily. No, the usual result is a burst barrel, such as the one depicted. A shot charge behind a stuck wad does not generally just blow the wad out the end of the barrel. If that has happened to you, you should have purchased a lottery ticket that day. Luck like that should not be wasted. |

I don't think so on that barrel. No sight bead makes it look like it was a longer barrel that has been cut down, or is one of the 18" barrels that usually have a heat shield(which would have blown off with the rupture). With those, I think the sight bead is on the shield instead of the barrel, and I'm pretty sure the barrels don't take screw in chokes. I could be wrong. OP claims it to be a 590 Mine does not have choke threads but it does have a screw in brass front sight bead. 20" barrel i am about 90% sure that is not a 590 |

Quoted:
double charge? -of powder? Unlikely. That scenario would likely crack the barrel at the chamber - not further down as shown. Furthermore, double-charges are RARE in factory ammo. Further still, the shooter was apparently using 2 and 2/3 " birdshot ammo but the gun is built to take 3" Magnum slugs; I bet it would survive a double charge of a light bargain walmart load. Looks like obstructed barrel. Could well have been a 20 gauge shell followed by a 12 gauge shell. |

Wait, no one has made a Glock joke yet? ETA: No Mossberg quality jokes either? Posted Via AR15.Com Mobile Mossy 590A1s have a stronger barrel than I think any other modern pump shotgun. I'll have to find an old article to prove it, but I think the military tested them and this was one reason why the 590A1 is a milspec shotgun. ETA: "20-12 follower." Never heard that before.

There are different models of 590's that I'm aware of, but the only differences I've seen are ghost ring sights, speedfeed stock, etc. Would be interested to know if there's some oddball 590 that looks different than what I'm used to.  ETA: Looking at Mossberg's site and variations of the 590, I don't see any models of the 590 like what you describe - the mariner 590 looks different, but that's obviously not what is pictured in the OP. Also, all the 590's listed are shown as 9-shot models If I've missed some variation that isn't listed anymore on their site, let me know. Just would like to know it exists for idle curiosity's sake. Nevermind, my mistake. I finally found it under the 590A1 section on Mossberg's site after hunting around some more. Had no idea they had 18.5" 6-shot models. Interesting. |

What was the temperature like outside that day? Maybe it was caused by rapid heating and cooling between stages? It would have to be frickin Antarctica and he'd have to be firing at full auto rates, but I'm just trying to figure out how in god's name that happened.

It's pretty close to going in. If I'd dropped it in from the chamber, it would have gone up quite a ways. Much further than just an inch or two from the chamber. That's an open bore, 20" length barrel. |

I am not sure what dynamic segment they were doing but he could have been laying down shooting under a structure and accidentally plugged his barrel with mud. The part where he thought he had a malfunction part is what is making me lean towards 20-12. He could have loaded the 20, the trigger went click and then he racked in another 12ga shell and then kaboom. |
