i think he is or was a member here as well ...
I was thinking along that line, what if ammo in mag blow, round in the barrel was normal, strange.
But from what I read, quickly, sound like all ammo accounted for?
Blocked barrel and blew the bolt back? Need a coffee.
That fellow is damn lucky.
This doesn’t compute. Anything resulting in overpressure will show on the brass, and this casing does not show it. The primer will flatten or smear. I’ve done it to many primers myself. The case head would be the second to show signs. It would expand and the primer pocket would also enlarge and the primer would fall out.
Then we get the fact that the deflagration or “explosion” is contained within the casing. How can such a volume of gas escape the chamber without rupturing the case?
I thing the previous round fractured the locking lugs. This round basically blew the bolt back without resistance. The gasses escaped the mouth as the boot was already pushed back out of battery by the time pressure was really on the rise.
IMO the bolt was incorrectly hardened like glass. Previous round or rounds Propagated cracks in the bolt, and this one finally fishier it all off, before it was able to reach full pressure thanks to blowout back out of battery and venting the gasses. Hense barrel appears ok. Remeber those lugs engage the barrel not the receiver.

Very glad to hear the guy is ok. I find these posts very interesting. It's very concerning that these rifles have had issues in the past. Not a good look for sako. Especially because they are a "high end" rifle manufacturer.
To hear about someone getting banned from ranges for blowing up rifles is pretty wild. He must be quite the chemist.

Not on the 75s or 85s, nor the earlier L- and A-series. Lugs engage recesses in the receiver.
Not the first large brand to have a batch of rifles blow up. I remember Browning had a bunch around 20 years ago where the barrels exploded and the barrel peeled back like petals, having split at each groove in the barrel. Savage had its 10MLii complaints as well.
No you can’t.

The shoulders on the 300 are further forward than the 338.
well i did. maybe the cut was different but i did.
oh no it was not him but a real idiot that was wondering why all his guns exploded ...
You’re good guy; I’m just going to leave this one alone.

Looking at the cartridge drawings with dimension and measurements, even the rammy-est guy could not make it happen. You'd physically need to drive the bolt home with a hammer to (maybe, in theory) make it fit once while damaging the rifle in the process.
Which seems petty of them.
