This came up on another thread- so I wanted to throw it out here for people to weigh in. I have had 2 animals go down at impact (both went "Hooves Up"), only to find that I had missed vital organs. On one (antelope) it's insides looked like jelly (shot it with my Husq using light magnum rounds topped with SSTs. Another I shot (Deer) with a 7mm mag. using PSPBs, and though the bullet lodged in the chest cavity, the vitals were untouched, but the top chamber of the heart was "blown out".
I was always under the impression that hydrostatic shock was the cause (as the internal damage seemed to indicate), but in looking up the issue (after I was corrected on another thread- Thanks for straightening me out Tailwind) I find that Hydrostatic shock is assumed to be a Myth and unproven.
I'm curious to see if anyone has a similar experience, and what the "ballisticians" have to say (yeah, I just made that word up.)
