Here's the jaw-dropping description from Extreme Shock's site (I know most of you have likely come across it in your travels, but still...): NyTriilium matrix particles? Come on. Can anybody explain in layman's terms what material they are actually using, and how it is formed into bullets? I saw the word "Tungsten" in there somewhere, I think, but can anybody elaborate? Anybody have some of this ammo (gasp)? Shot any? And no, I'm not thinking of purchasing Extreme Shock . I'm well aware of the inadequacy of frangible rounds for general defensive purposes. But I am extremely curious to find out about this stuff.
