Winchester Defender 9mm Luger +P Ammo 124 Grain Winchester PDX1 Bonded Jacketed Hollow Point

The FBI tested Winchester PDX1 ammunition to see if it could withstand life-threatening scenarios in the real world. Winchester’s patented bonding technique gives this ammo remarkable expansion and noticeable velocities at a variety of ranges. To achieve regulated expansion and increased weight retention, the engineers fused the copper jacket and lead core together. To mimic a real-world threat, the bonding can also assume the strongest barriers at different ranges and speeds.

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.
