Editing Hydrostatic shock (section)

===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.<ref>{{cite book |first=Peter |last=Capstick |title=Death in the Silent Places |year=1981 |location=New York |publisher=St. Martin’s Press |page=152 |isbn=0-312-18618-5 }}</ref> 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.

{{blockquote|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.

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."<ref>A to Z Guide to White-Tailed Deer and Deer Hunting, Randall Gilbert, 2003, Woods N’ Water, Inc., p. 106</ref> Dave Ehrig expresses the view that hydrostatic shock depends on impact velocities above {{convert|1100|ft|m|abbr=on}} per second.<ref>Muzzleloading for Deer and Turkey, Dave Ehrig (2005) p. 64</ref> 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.<ref>The deer hunter’s almanac, Sid Evans (1996) p.66</ref> The North American Hunting Club suggests big game cartridges that create enough hydrostatic shock to quickly bring animals down.<ref>''The Game Rifle'', The North American Hunting Club (1992)</ref>
