Description The ultimate combo pack in self defense! Winchester offers a double dose of personal defense loads that can be used specifically for The Judge or separately in your 45 Colt or 410 shotgun. 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. Upon impact, the jacketed hollow point initiates expansion up to 1-1/2 times the size of the original bullet diameter. The unique notching in the bullet creates six equal segments creating maximum expansion on impact. Finally, Winchester has chosen nickel plated brass to maximize reliability through smooth chambering and case ejection. For the 410 Bore shells, in addition to the 12 pellets of plated BB shot, this load also features 3 plated Defense Disc projectiles. Loaded in black hulls with a black oxide high-base. Firearms, trailers, and some accessories are only available for purchase in stores. Each location follows all BATF and individual state/county/city laws to insure the desired product is legal for sale.
