Since Niall used Grok...
I asked:
"If a human is shot by a .30-06 bullet in the neck area and the bullet deviates downwards after entry and stays in the upper body cavity, is it possible that the skin/fascia of the lower neck and upper chest area could "balloon" out significantly as a result of the transfer of energy of the bullet into the body?"

Yes, it is possible for the skin and fascia in the lower neck and upper chest area to balloon out significantly following such a gunshot wound. This effect can occur due to the high-velocity .30-06 bullet's energy transfer creating a large temporary cavity in the tissues, which stretches and displaces them outward—potentially visible as a momentary bulge or ripple. Additionally, if the bullet path or cavitation damages airway structures (e.g., trachea or larynx) without directly perforating them, it could lead to subcutaneous emphysema, where escaped air accumulates under the skin, causing more sustained swelling or ballooning in the affected regions
