I'm in the camp that needs a lot more convincing. Others have already posted about the various types of bullet damage, but in a "hydro" sense there are only two - hydrostatic and hydrodynamic.
Maybe a more accurate question is, "How much shock is caused by a hydrostatic wave?" My answer - Very little.
With all respect to Mr. Howell, I believe "hydrostatic" is the correct term for the energy wave that results in water-based tissue upon bullet impact - correct in that the water doesn't move (remains static). The wave is a result of the elasticity of water.
Body tissue, be it man or beast, is able to absorb this type of energy by not cotaining it - we stretch. This is why the "pop can" analogy doesn't fit.
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.
