So, is it the next greatest innovation in bullet technology, or is it just hype?
First, let's analyze their claims.
They claim to be in use by many LE agencies although I don't know of any that use them.
From their website:
Over ten years in co-development with Special Operations Groups and Federal Law Enforcement, the new ExtremeShock™ Explosive Entry tactical defense rounds represent the ultimate refinement in lethal bullet technology. The compressed Tungsten-NyTrilium™ Composite fragments upon impact, leaving a wound channel of catastrophic proportions....E-Shock rounds are engineered to expend maximum energy into soft targets, turning the density mass into an expanding rotational cone of NyTrilium matrix particles, causing neurological collapse to the central nervous system.
Did you get all of that? I don't mean to mock, but what the heck is Tungsten-NyTrilium™? Nobody seems to know for sure. It would seem that it is nothing more than a proprietary marketing buzzword for some sort of magical powder in the bullet.
Also from their website:
An AFR round has completely dumped its entire energy in the first 7", completely disintigrating the ballistic gelatin
A FangFace AntiTerrorism round shows similar energy transfer, with added penetration to a full 14"
ExtremeShock's Unique Nytrilium-Tungsten composite material offers many advantages over other rounds that are designed to break-up on impact.
So, these rounds were apparently designed to "dump energy" and limit penetration it seems.
The problem with these claims is that this is exactly the opposite of what conventional wisdom and testing has shown is needed and desired.
FBI studies have determined that defensive ammo should reliably penetrate a minimum of 12" in ballistic gelatin in order to be an effective manstopper on the streets.
Secondly, when tested, these bullets failed to perform exactly as they were advertised.
The well known website Box O' Truth tested some of these rounds and here were their results.
The conclusion is this, Extreme Shock ammo is marketing hype and could get you killed. Use premium hollow points made by reputable companies who have made their reputation in the labs and on the streets, such as Winchester, Hornady, Speer, Remington, etc...
