Winchester PDX1 Ammunition was tested by the FBI to see if it can stand up to real world, life threatening situations. This ammunition has impressive expansion and notable velocities at various ranges thanks to Winchester’s proprietary bonding process. In PDX1 ammunition, Winchester engineers have created a self defense load that exhibits controlled expansion and a higher weight retention.

In addition to the 12 pellets of plated BB shot, the 410 Bore load also features 3 plated Defense Disc projectiles. Loaded in black hulls with a black oxide high-base. Originally developed for the Taurus Judge, these shells can also be used for varmint hunting and pest control.
