Edward Wilks - Ammo Testing: Liberty Civil Defense .380

Описание: Illustrated Principles of Kinetic Energy and Hydrostatic Shock

I will try to make this brief and simple. When we need to stop an attacker or a threat, our objective is to achieve three things: Placement, Penetration, and Damage. Placement means hitting the area we want. Penetration means getting through any "cover," which could range from the attacker's muscles, fat, and ribs to things like a wallet in a pocket or the door they are hiding behind. Damage means disrupting or destroying vital organs or functions like the brain, heart, or central nervous system.

Typically, damage is referred to as the "wound channel," which is created by a high-speed projectile entering an area of fluidic mass resistance (like soft, liquid matter) and then expanding under hydraulic pressure sufficient to create a massive shock wave which destroys, disrupts, and displaces that watery medium, thus tearing and opening internal organs to cause massive hemorrhaging.

A very fast bullet can penetrate well, and "may" create some hydrostatic shock. A hollow point at the same speed may not penetrate as much, but "should" create some hydrostatic shock. Ideally, we want both. Most modern hollow point cartridges are now manufactured with projectiles and velocities that will penetrate hard media, but expand on liquid media.

In this video, we are attempting to illustrate several things. For example, (shot 1) objects struck from the front, CAN move TOWARDS the muzzle, and NOT necessarily away from (or in direction with) the bullet's line and path of travel. This is because the amount of media that is blown out of it acts as propellant to force the object back towards the shooter. (This is in harmony with Newton's 3rd law of physics.) Also, (shots 1&2) notice that there is only a small amount of difference between a fast .40 solid bullet, and a fast .40 hollow point bullet. But, there is a HUGE difference (shots 3&4) between a slow solid .380 bullet, and a much faster hollow point .380 projectile.
