Except for the fact that dynamite was designed to damage with its blast, whereas guns are designed to kill by penetration. Injuries from
hydrostatic shock are still debated and that's about the shock the bullet causes by actually penetrating the body at high velocity, not a bullet penetrating surrounding fluids.
This sounds like those rumors that Desert Eagle would kill by shock, even if the wound delievered wasn't fatal. Highly doubtful.
It's more reasonable that those people just fainted by the shock.
Unless you meant the fish would die because of the hole in the barrel afterwards. I can agree to hat
