Polycase Ammunition: make your 9mm tumble
Check this out:
It's a round nosed projectile that spins, creating increased stability, and then tumbles to impart more energy into the target. It's also lead-free, being a copper-polymer injection molded concoction, which also probably accounts for the light weight. Some addition information can be had here: http://www.ammoland.com/2015/01/ammu...#axzz3f7dx38kG
The largest advantage I see is for defensive ammunition in countries that prohibit the use of expanding ammunition like hollowpoints- you know, Italy, Estonia, Czech Republic, that place with Chris Christie...barring a 10mm or something hot enough to open up a soft point, this might end up being quite the alternative!
