Personal favorite ammo. Barrier blind+1700fps is brutal. Mile High had the best price by far as well!
The non-expanding ARX is injection-molded from a specially blended polymer-copper matrix that is designed to be tough enough for an all-purpose defense round. Upon entering soft tissue, the specially designed grooves in the nose harness the soft tissue and constrict, pressurize and eject it at 1.5 to 2 times the directional speed of the bullet. This is the well-known Venturi Effect. As the bullet penetrates, it tumbles in a controlled, predictable fashion that delivers consistent terminal performance that equals or exceeds conventional hollow-point designs without over penetrating.
