Well, not exactly. If we want to be precise and rely on verified scientific and forensic documentation, the critical threshold isn't just above 1400 or 1600 joules. In fact, there are no documented cases of survival after a complete intraoral gunshot wound beyond 600 joules. An intraoral shot refers to a very specific scenario: the barrel is fully inserted into the mouth and the shot is fired vertically, passing through the hard or soft palate and transmitting energy into the cranial cavity. This is not a tangential or accidental wound, it's a direct internal trajectory. Beyond 600 joules, the pressure and destructive force generated make survival biologically impossible. So no, it's not only above 1400 where survival becomes unlikely, the threshold of certain lethality is significantly lower. If someone claims otherwise, science requires that they provide verifiable clinical sources. On the other hand, below 600 joules, there are documented cases of survival from intraoral gunshots, but only when the trajectory avoided structurally fatal damage.
