Where the action is.

Suppose one took an action like the one below, snapped a loaded round in the end of the bolt put the bolt into the receiver, snugged it in a vise and pulled the trigger.

What would happen?

The case would rupture with a mellow POK-FsszEEET! sound, or just a PokFFUUHhhh in some cases......there would be an orangey/yellow flash with just a tinge of deeper red......A billow of grubby grey smoke would fill the area, streaked with a few burning powder kernels and the bullet would roll acrost the floor and lay against the baseboard. Depending on where the case ruptured, it may be propelled sidewise with enough force to puncture skin.

or not

Most often there will be unburnt and melted powder kernels all over the floor.
 
not so sure about the ruptured case
all ammo i have seen in fires, just popped the bullet.
takes 40k or so the rupture brass, much less to pop a bullet out the end.
bottom line no combustion chamber( chamber/bbl) very little pressure.
 
Somewhere on my computer I have a High Speed Video of exactly that test. We used a M1919 Machinegun bolt rigged to an angle plate to fire straight up. The .308 went off with the bullet going straight up about a foot and falling back almost into the case. Case neck split. We did this also with .308 blank rounds and got more fragmentation from the case, but no pieces penetrated 1/2" celatex at 12". If I can figure out how to post video, I will.
 
I think it depends

I know someone who lost his middle and ring fingers left hand. He kept an old 32 Special loaded round on his desk and had a habit of picking it up and nervously tapping it on the desk top, rim side down. it went off and severed his two fingers.

We did it as part of an accident investigation. We are one of the US Army Research & Development labs. This was similar to a test that GEN Julian Hatcher did here and wrote about in Hatcher's Notebook. He use an electric soldering iron wired to touch the primer. Covered the whole thing with a cardboard box. No video, but nothing penetrated the box. His test was to see what would happen to ammo in a fire. Ours was due to a supposed blank round, hang fire, going off as it was ejected from a salute rifle at a cemetery.

It takes 40,000psi to stretch a case, get it back to the boltface. They rupture at just a few thousand lb

It makes a big difference whether the primer fires or the powder just passively ignites. In this case I allowed for primer.

And of course type of round makes a big difference. Some pistol cases will actually pop perty good.

What I find interesting is that it's entirely possible to insert a mild 308 or 30-06 hunting round into a barrel, fire it with a nail and have no parts flying about.

And pipeguns are all over the net, nothing holds them together https://www.youtube.com/watch?v=tN-ivQnAYCI

Actually when in my youth we had a loaded .32 Special round that my older brother got from somewhere. One summer a neighbor had a brush fire and there was a bunch of red coals left. I threw the loaded round into the coals and after a minute or so there was a loud bang. That's about it.

In 'Hope And Glory', a futzy liddle 80's fantasy about the bombing of London some kids threatened to shoot another by clamping a loaded round in a vise, menacing with a hammer and nail. To this day many of my generation are believers....

Time may have loudened the memory :)

We get a lot of loaded rds, paint cans, aerosols, lp canisters and such in our burn piles. Now some of the dud fireworks get perty spectacular!

At the range there are people who get dud .22 rounds and throw them in the burn barrel. When it gets full and someone lights it on fire you can hear the dud rounds go pop. That's about all that happens; no bullets come whizzing out of the barrel.

I'm left eye dominant which explains why I shoot left handed. Bought my first true LH rifle, a Rem 700 BDL in 1975 or 76. Still got the action and I think the stock. Most dealers then didn't know that LH stuff even existed. Throw and swing a bat lefty style. My dad was the same way. I converted my Ithaca 37s to LH safety too. Used to be a place out in Oregon I believe called Lefthander's Heaven
