AR15 AR 15 ammo test: Winchester PDX1 .223 Defender



(from Dec 2013)

The AR-15 is becoming more common for home defense than ever before. In this video I explore one of the premium self-defense/home defense rounds made .223 Remington, the Winchester PDX1 Defender 60-grain Split-Core Hollow Point, part #S223RPDB. The test barrel length was 16".

The "split core" refers to the bullet having two wounding mechanisms; it's a fragmenting round (like M193) combined with a hollowpoint bullet. The idea is to get the massive temporary cavity caused by a rifle, which gets magnified and turned into permanent damage by the fragmentation, combined with a deeply-penetrating hollowpoint bullet that can penetrate the vital organs (if, of course, your aim is good enough).

I used genuine professional organic 10% calibrated ballistic gelatin to determine the penetration and expansion characteristics.

Note: I'm not making any claims for these videos other than that these are the results I achieved, in my own testing, from the stated pistol(s). I have no intention to make a blanket endorsement or indictment of any product, only to review and report what I found in a given instance. Obviously it is incumbent upon each individual to conduct their own research and make up their own mind about which defensive ammunition is best for their own purposes, in their own firearms.

The standards I use to judge bullet performance are the standards established at the 1987 and 1993 Wound Ballistics Conferences, and subsequently adopted by the FBI.
