20rds – 9mm Winchester Defender 147gr. PDX1 Bonded JHP Ammo

Winchester Ammunition 147 Grain Jacketed Hollow-Point (JHP) Ammo Details

Winchester’s Defender ammo line is specifically engineered to maximize the terminal ballistics set forth by the FBI’s exacting test protocol for personal defense loads. This 9mm cartridge’s 147 grain projectile has had its jacket and core welded soundly together via Winchester’s proprietary bonding process, so the two remain virtually inseparable even after having passed through the barriers that are likeliest to impede a bullet’s performance in real world scenarios.

This bullet’s hollow point has received notches to ensure that it expands reliably along six axes, even at lower velocities. The bullet’s hollow point has been formed in such a fashion as to ensure that it expands up to 1.5 times its original diameter. With such superior weight retention and terminal performance, there is little wonder why the FBI has preferred PDX1 Defender rounds for their agents’ service pistols in the past.

This cartridge further offers a nickel plated brass casing, the advantages of which are trifold: improved lubricity for more certain feeding and ejection in a semi-automatic firearm, improved resistance to corrosion, and improved visibility during chamber checks in low light conditions.
