Dwight, Dosen't the 9MM round headspace on the case mouth and the step in the chamber is necessary for this purpose if no other?

above. In the examples I have seen, the fractures do not extend through to the relieved breechblock face, suggesting that escaping breech pressure is not the culprit. As a WAG, I wonder if it might rather be a result of impact fracture of the breechblock against the barrel/receiver face?

It could be that this bolt damage was the result of the weapon fireing out of battery, split the unsupported cartridge and the high pressure escaped upwards taking a portion of the bolt face with it?
