Definition of over penetration as used in this article:
A projectile passes through an intended target or backstop and is still capable of causing a person serious physical energy or death.
Now That’s Power!!
SlapShot USA’s technology mitigates danger to surrounding people and property by effectively transferring energy developed within the firearm across a distance and into the target. When a bullet passes through the intended target, only a fraction of the available energy has been transferred to the intended target. Over penetration is dangerous when it leads to energy being wasted in unintended directions and on unintended targets. With the SlapShot PHD, the risk of over penetration is reduced by rapidly dispensing the energy into the intended target. This produces an explosive pressure wave inside the target which simultaneously interrupts the function of multiple internal organs, accelerating incapacitation beyond mere blood loss. Temporary cavities 20 times larger than the projectile and crush cavities six times the diameter of the projectile are evidence of rapid energy transfer (8).
Terminal ballistics can be illustrated by comparing the difference between 500 pounds of sand and a 500-pound rock. How will each act when dropped on top of you. Both carry the same potential energy, but their different physical structures will cause energy to be transferred differently upon impact. Your body probably would withstand the energy from the sand pile better than the energy from the rock. The rock’s physical characteristics will force the body to immediately absorb the entirety of its energy. The sand’s physical characteristics will diffuse the energy as the particles of sand are spread out allowing the body to absorb the energy at a slower rate. In the end, the difference is in how the energy is transferred into your body. The SlapShot PHD series is optimized to dump its energy rapidly, creating an explosive pressure wave.
