"Hydrodynamic damage is very real, and based on high velocity fluids ripping into adjacent tissue. While this damage can be extreme it's very localized. "
You hit the nail on the head and to extend that may I ask why accuracy would make any difference? If that shock wave goes all through the connected tissue in the entire body (it must) and because of the basic characteristics of wave energy including minmal energy loss in subsequent waveform energy transfer (hence radio waves that go forever into space) and repeated reflection through the body that means every area would be hit repeatedly.
And therein lies the essential rub. Wave energy is extremely efficient in transfering energy with minimal loss (that would be "dumping") and any bullet anywhere in the body would kill as efficiently any other... IF "hydrostatic shock" actually kills...
