I think that there is a big misconception over hydrostatic shock here. I think it is the same as the misconception of "knockdown power". As said, the hydrostatic shock of an expanding bullet, is distributed over time. That is why unless you hit major bone, you are not usually going to "knock" anything down!
Also, if hydrostatic shock were as some people mistakenly believe that we are talking about, it wouldn't matter where you hit the animal in the body, the shock wave would take care of a poor shot and KO the animal!
That is not true, and that is not what the believers of hydro-shock are talking about! H-shock does do a lot of damage in the surrounding area, whether the bullet exits or not, and this leads to quicker blood loss and death!
Lastly back to the original thread, if you are disappointed in a good double lung, blood trail and 15 yard tracking jobs, you are in for a lot of disappointment!
