Pluspinc; you mean that the price of airfare and food and lodging is NOT included in the $75??? I may have to reconsider my comment about how reasonable the price of your course is!
AC; anyone who carries HydraShoks in a 1911 is a person who I respect immensely! I am surprised you find the blast of 125gr. .357 JHP's to be intolerable. My younger daughter uses this very load. Of course, we both wear muffs AND plugs when shooting. She has a Ruger SP-101 with 3" bbl., Mag-Na-Ported.
Buzz knox: regarding this hydrostatic shock phenomenon, the general feeling (but it is controversial) is that it is NOT seen with low velocity bullets, such as handgun bullets. Some even question whether it is seen with high velocity bullets.
This was the problem with the goat study. The 'authors' tried to say that handgun bullets could cause an increase in the pressure of the carotid arteries, and this adversely affected the brain, causing incapacitation. The problem is that (assuming that the tests are real) they went to the trouble of putting a 2 kHz pressure tranducer in the carotid artery, and then recorded its' output on the EEG leads, which record electrical activity, NOT pressure.
I am unaware of any scientific evidence that the hydraulic shock phenomenon actually exists. The vascular system is very compliant (flexible) and I doubt a pressure wave would be able to travel all the way down to the smallest vessels which actually feed oxygen to the organs, the capillaries, and damage the tissue. During the regular pumping of the heart, the pressure wave caused by contraction is gone by the time you get to the capillaries. Temporary expansion of larger blood vessels occurs with every heart beat, so hypothesizing that a larger expansion due to hydraulic shock could cause damage is understandable, but I don't think it is likely. Certainly Dr. Fackler did many autopsies on people who died of high velocity bullet wounds, and never found evidence of hydraulic shock damage.
The kinetic energy dump is much the same thing; while some people think that the kinetic energy is magic, I feel that the destruction done to the tissue by the bullet is the real important thing. Certainly tissue damage reduces the kinetic energy of the slug, but I don't think the rate of transfer of kinetic energy (at least in handgun bullets) is all that important. A slow, fullwadcutter cutting a nice sharp hole through vital organs would work just fine, IMHO. If it were moving more rapidly, it may work better, but I wouldn't say that it would have to be slowed rapidly (dump its' kinetic energy) to be effective. One of the perps in the 1986 Miami FBI shoot out took a .357 bullet right in the face; it put him down immediately. Unfortunately, it lodged in his sinuses, doing no real permanent CNS damage, and he woke up a minute or so later, and started to try to shoot back. He certainly had a lot of kinetic energy transferred over a short period of time with only temporary incapacitation.
Ice Man; I am not sure that pluspinc missed the boat on the shotgun pellet embolus. I assumed he meant that the pellet would enter a blood vessel, and be carried to a distant site, where it stopped the blood flow and caused tissue damage. This would indeed be an embolus. If he was describing the blockage of a blood vessel at the site of the pellet entering the blood vessel, then this would be a thrombosis.
Pluspinc; will send snail mail addy and await video. Thanks very much for the kindness. Walt
