Another interesting thing to consider that was mentioned earlier in this discussion is that since this was not a catastrophic failure, the shooter could just have stopped shooting and all would be well.
He could have, IF he had noticed the problem and heeded the warning of impending major failure.
Well, who would be that unobservant you ask...
I know of three instances where a shooter had ample warning that something wasn't right, yet persisted and had a catastrophic failure.
In fact, I'm of the opinion that a sudden unexpected failure is rare , and that the gun will usually give warning of it's distress before the catastrophic event.
It's up to the shooter to be in tune enough to recognize it, and STOP to take stock of the situation should anything unusual occur.
The only exception might be in combat.
