[QUOTE="Murtfree, post: 2515761, member: 111090"] I guess since there doesn’t appear to be a clear definition as to what “Hydrostatic shock“ is or if it exists, some of us may have our own definitions. I believe it exists to some degree in all calibers but doesn’t meet my definition unless you are approaching 4000FPS. And therefore I use it to harvest thin skinned game such as deer with small caliber ..17 up to .25 cal. I can give examples of deer killed with a 30grain 17 caliber bullet, 55 grain .22 caliber bullet, 87 grain bullet in 6mm as well as .25 caliber. All animals were hit in the ribs full broad side and bullets never exited, and the animals never took a step. It was nearly impossible to find the entrance wound as well and there was no blood loss. Without careful examination the deer appeared to just drop over dead for no reason. The autopsies revealed a different story. When the chest cavity was opened most organs were barely identifiable. Lungs were completely pulverized as were most organs within the rib cage. There weren’t any functioning organs remaining and this is my definition of hydrostatic shock. And when killed in this manner this is no meat loss. In my opinion there is no reason to discuss hydrostatic shock on larger heavier animals such as bear since you need a heavier constructed bullet to reach the vitals which usually can’t be pushed to the velocities needed to cause this type of damage.
