lol.. me too but there is this study

Human autopsy results have demonstrated brain hemorrhaging from fatal hits to the chest, including cases with handgun bullets.[4] Thirty-three cases of fatal penetrating chest wounds by a single bullet were selected from a much larger set by excluding all other traumatic factors, including past history.
In such meticulously selected cases brain tissue was examined histologically; samples were taken from brain hemispheres, basal ganglia, the pons, the oblongate and from the cerebellum. Cufflike pattern haemorrhages around small brain vessels were found in all specimens. These haemorrhages are caused by sudden changes of the intravascular blood pressure as a result of a compression of intrathoracic great vessels by a shock wave caused by a penetrating bullet.

Ammunition selection for hunting
Hydrostatic shock is commonly considered as a factor in the selection of hunting ammunition. Peter Capstick explains that hydrostatic shock may have value for animals up to the size of white-tailed deer, but the ratio of energy transfer to animal weight is an important consideration for larger animals. If the animal’s weight exceeds the bullet’s energy transfer, penetration in an undeviating line to a vital organ is a much more important consideration than energy transfer and hydrostatic shock.[79] Jim Carmichael, in contrast, describes evidence that hydrostatic shock can affect animals as large as Cape Buffalo in the results of a carefully controlled study carried out by veterinarians in a buffalo culling operation.
Whereas virtually all of our opinions about knockdown power are based on isolated examples, the data gathered during the culling operation was taken from a number of animals. Even more important, the animals were then examined and dissected in a scientific manner by professionals. Predictably, some of the buffalo dropped where they were shot and some didn't, even though all received near-identical hits in the vital heart-lung area. When the brains of all the buffalo were removed, the researchers discovered that those that had been knocked down instantly had suffered massive rupturing of blood vessels in the brain. The brains of animals that hadn't fallen instantly showed no such damage.

Dr. Randall Gilbert describes hydrostatic shock as an important factor in bullet performance on whitetail deer, “When it [a bullet] enters a whitetail’s body, huge accompanying shock waves send vast amounts of energy through nearby organs, sending them into arrest or shut down.”[81] Dave Ehrig expresses the view that hydrostatic shock depends on impact velocities above 1,100 ft (340 m) per second.[82] Sid Evans explains the performance of the Nosler Partition bullet and Federal Cartridge Company’s decision to load this bullet in terms of the large tissue cavitation and hydrostatic shock produced from the frontal diameter of the expanded bullet.[83] The North American Hunting Club suggests big game cartridges that create enough hydrostatic shock to quickly bring animals down.[84]
