sunray, should have read 100/120,000 psi.
has nothing to do with what cartridge the action is finally chambered for. Liability requires that the ACTION survives this level of pressure without blowing up. At the lower proof levels, they need to survive multiple firings.
Sort of like crash testing for rifles.
Every modern and many older actions (at least by design) are way stronger then the cartridges they fire.
Still doesn't save a 'rocket' scientist for subbing Unique for H4831 though. Just avoids any nasties from the occasional hot load.
Maybe these pics should be forwarded to the Mythbusters crew. Seems shooters have no issue with splitting barrels.

I saw an old SMG barrel when I was in Weapons Tech school that had had a live round down the barrel while a blank firing apparatus (BFA) was attached., Just like the pics, banana peel city. There was another GPMG (old .30 cal) barrel that was split right in two because a bore brush had been left in there. They had them mounted on plaques to show the students the effects of a blocked barrel. So apparently it doesn't take that much.
I wonder if the location of a blockage makes a difference? On that Mythbusters TV show they took that shotgun and pushed it into the ground, so there was an 8" tube of dirt in the end of thre barrel, and that barely did any damage also... maybe closer to the breach has more effect?

ummmm...please explain why you think because it happened to the gun you used, it will happen to all
what you guys did may have been a fluke and likely wouldnt happen all the time.

I know what you mean ...
One thing I would have liked to see is a proper squib load sent thru the Carcano rather than try to hammer a bullet down the muzzle ...

My father had a M37 in his shop that had a 20 accidently fed into it, then a 12 behind it.
What a mess.
The action on my brother's .280 came from a rifle up here that had the barrel split from just in front of the breach , in two pieces.
This was from condensation.
It has happened!
Those idjits should have talked to some real experts before performing their stunts, they may have found out some interesting stuff about how pressure buildss and just what it takes to blow a barrel.

A fluke? Likely wouldn't happen all the time? Are you really that stunned?
You can roll your eyes all you want but this is the kind of stupid question from newbs that get people killed.
I have a great suggestion... why don't you try the experiment yourself with a bunch of different guns and offer a qualified opinion.
The most painful thing I ever saw was a barreled action to a BRAND NEW Model 70 Featherweight that was taken hunting for the first time. He got a little ice in the muzzle. The barrel tore open into three pieces, about 14-16 inces long. At the muzzle portion, each of the three pieces split right down the center for about an inch, and the whole thing looked almost like it was done on purpose. I thought it would have made a cool table lamp.

And that's why I say that show is dangerous. People feel because these "Experts" demonstrate somthing on tv, it must be real. I remember the episode where they showed if a boat is sinking, it will not suck you underneath with it. In their controlled enviroment, everything was fine. But how many people lost their lives after jumping off a sinking ship, and getting sucked in the undertow and drowning. And I'm telling you, were going to have guys plugging their muzzles because the mythbusters said it's safe to shoot a gun after it's been plugged. Heck, we'll probably even have guys stuffing a couple extra bullets in the barrel in the hopes of getting some more lead into the air.
The armourors course for Glock actually teaches you to clear the barrel with a second shot down the plugged barrel. It was the over engineering was meant to save a soldiers or LEO's life if a deadly force encounter where a squib happens and in the past effectively took the operator out of play.
I wanted to blow up an old CIL 12g pump for use in the firearms training course. Tied it to a target rack on the range, opened the action, stuffed a 20g shell up the pipe, and put a 12g in behind it. Closed the action and ran a string behind a burm, and let'er rip. Nothing happened. Did it a second time - same result. Finally plugger that last 2-3 inches with dirt - that did it.

Do you really believe that anyone would actually plug their muzzle on purpose?
