I am having trouble with content of the original post
1) Monolithic bullets were not invented because of the lead ban. The Barnes X was introduced in 1989 (initial concept ocurred in 1985) approximately 20 years before any lead ban occured for rifle ammunition.
2) Hydrostatic Shock is an oxymoron. The word hydrostatic refers to the pressure caused by a fluid when that fluid is at rest in a confined space; e.g. fluid at rest inside the walls of a cell. Once fluid is moving (caused by a bullet in this case) it is no longer static; therefore, in essence all damaged not caused by the impact of the bullet itself against tissue would be hydraulic in nature based on the common use of the words as opposed to labels created by the hunting/bullet industry.
3) "The reason why animals drop instantly with chest shots that do not directly strike the CNS, is due to hydrostatic shock transfer to the spine which passes through to the brain. Any high velocity cartridge along with a good bullet properly selected for the particular animal size imparts over half its energy within the first few inches of penetration, creating a shock wave. This electrical shock wave travels outwards via the rib cage until it reaches the spine and then continues through to the central nervous system in the brain (CNS). The result is an immediate loss of consciousness as the body shuts down for diagnostics (temporary coma)."
What research supports the above statement? I am aware of no research of any scale using scientific methods such as video-taping of animals shot and their reaction followed by necropsy. Obvioulsy, if a shot destroys the spine or neck vertebrae and the animal drops in its tracks we can draw a conlusion. But if there is research out there that shows animal 1 was being video taped, shot in the chest cavity, immediately dropped, and a necropsy showing bruising to the tissue around the spine and animal 2 was shot in relatively the same spot and ran-off and died 50 yards later and the necropsy showed no brusing to the tissue around the spine I am completely unaware of it. Absent such research, your statement is likely conjecture and not fact.
Animals may drop immediately from non-CNS shots for various reasons - such as 1) the sudden experience of pain (much like when a human touches a hot stove - they jerk their hand back even though no kinetic energy is at play, 2) the structural breakdown of both shoulders, 3) disruption of the nerve complex in the front shoulder(s).
So in essence, I am asking for the scientific information that supports the original post. By the way, I love monolithic bullets.
