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 3 pellets of Grex buffered 00 buckshot, this load also features a 1 oz rifled slug which creates a tight pattern for extra protection. Loaded in black hulls with a black oxide high-base.
