While having that happen does suck, I would like to know if the round would have gone kaboom in ANY gun it was attempted to be fired from.
Still sucks though...
Yes it does.
This has been making the rounds on the various gun forums.
Here is a reply from one guy I thought was interesting:

Looks like a case head failure to me.
The typical "soot" left bay an overpressure load isn't there although he may have wiped it off.
From what is left of the case I think I can even see an inclusion that would have helped it to let go.
Lots of gas damage with the split wood and all but I wouldn't call it a catastrophe.
Loosing the lower end of the bolt is typical in those cases, you get a fracture right down the ejector recess just like that and the extractor gets pulled out when the brass shoves out and up on the stud at the same time.
Even with the best reloads or factory ammo you can get a head failure. That my friends is why you always wear your eye protection when shooting. No way to tell when you are going to get a bad case.
I have seen them from the factory. Things happen, that is why we take precautions.
Very few KS's are "catastrophic" where barrels split , bolt lugs fail and "shrapnel" goes flying all over. Most of the time the case head lets loose long before the structure of the rifle is damaged. Some rifles are tight enough that you won't know till you try to cycle the bolt. 721/722/700 Rems are almost famous for it. You end up beating the bolt handle clean off the gun with a mallet and can't get it open, finally get it open only to find brass blown down the ejector hole, the recessed bolt face split out and mushroomed no extractor and the thickest rim you ever saw on a case.
In the late '40's they (SA and the Army) tried to "blow up" an M1 Garand. They realized that during the whole of WW2, in battlefield conditions, with millions of rounds fired through them that none had catastrophically failed.
During their attempts to "blow up" an M1 they used the same powder used for the 70,000 psi proof loads and continued loading, firing and examining the M1. The test rounds were fired in a pressure test gun and a Japanese Arisaka bolt action rebarreled to 30.06 as well as the M1 Garand. They eventually reached a point where they stopped testing the rounds in the pressure test gun for fear of damaging it. The M1 and the Arisaka soldiered on. Eventually the Arisaka self destructed. The M1 was left to go on by itself. Based on earlier (while still using the pressure test gun) loading - powder charge increase vs. pressure increase - they got to a point where they estimated a pressure of 140,000 psi. The case failed (not the rifle) and blew out. This resulted in the trigger assembly floor plate blowing off the trigger housing, the stock broke, they also saw a small bulge in the bottom of the bolt part of the way back towards the rear of it. The receiver, barrel and bolt lugs were intact and undamaged. The replaced the broken/warped parts and continued firing standard ball ammo in that M1.
This rifle is not a GI M1 Garand but a cast receiver commercial gun with part of questionable origin (might be surplus GI, might be new commercial parts). My point is not to convince you it's okay to fire questionable ammo in your GI M1 Garand, just to say that they are darn tough and dependable, but if you reload, you better know what you are doing - or stick to GI ball ammo.
