In the shooting sports, safety always has to be your number one priority. Even if you have a safe load, if the barrel is obstructed in any way, such as with mud in the barrel, a squib bullet, or a bore-sighting tool left in the barrel, the barrel can blow up, pealing back like a banana skin. Serious injury or even death can result. Below is an amazing video showing a catastrophic barrel failure caused, presumably, by a barrel obstruction — probably mud or dirt. You can see the barrel blow apart, starting at time mark 0:25 seconds.
The rifle is a Browning stainless A-Bolt, caliber unknown. We don’t know for sure, but the barrel probably became obstructed when the shooter allowed the gun to rest muzzle down on the ground, so some mud collected in the bore. Below, we’ve grabbed five frames from the key section of the video. You can see the barrel split into two segments. This shooter, who was NOT wearing eye protection, was uninjured. He is is lucky that the action held and no metal shards blew backwards.

While its easy to blame it on operator error….
It is likely it was simply a failure of the stainless barrel.
416 as used in most barrels is a BRITTLE material.
This is more common than I am comfortable with.

Sako had a rash of stainless failures and a recall. But it didn’t get a lot of press.
There have been unexplained blowups of stainless pistol barrels as well.
I will stick with a less brittle steel like 4140/4150.

Stainless is brittle in sub-zero temperatures. I would surmise from the clothing that the ambient temperature is not that cold.
The failure seems to originate from the muzzle, lending credence to the theory that this is a partial or low-grade obstruction. Even water down the bore can lead to such a failure. Covering the muzzle with a condom or even a patch of duct tape will help prevent this and will not affect pressure.
