Winchester PDX1 Defender .45 ACP 230gr Bonded Jacketed Hollow Point 20/Box - Brass Casing

Winchester PDX1 Defender .45 ACP 230gr Bonded Jacketed Hollow Point 20/Box delivers maximum lethality when threats are imminent, and is designed to maximize terminal ballistics as defined by FBI test protocols. This ammunition offers impressive expansion and notable velocities at various ranges, and utilizes Winchester's proprietary bullet bonding process. The lead core and copper jacket of the bullet is welded together to obtain controlled expansion and achieve higher weight retention. The purpose of bonding the two materials together is to ensure that the dense, but soft, lead core does not separate from its jacket when the bullet makes contact with its target and encounters resistance. When a bullet’s core and jacket stay together, maximum weight is retained, which produces greater momentum that results in deep bullet penetration. However, if the bullet comes apart, or fragments, each individual piece of lead and copper will not penetrate as deeply as the heavier collective whole; therefore the bullet or bullet fragments might fail to reach a target’s vitals. Bonding mitigates the risk of fragmentation and therefore decreases the risk of bullet failure. Bonded jacketed hollow point bullets are designed to tackle the toughest barriers at varied ranges and velocities. This bonding process also maximizes penetration even as the bullet travels through tough, destructive barriers such as glass, drywall, metal and/or fabric, hence the term "barrier blind". Upon impact, the jacketed hollow point bullet 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. The nickel plated brass maximizes reliability through smooth chambering and case ejection. Most self-defense situations occur at night in low light conditions. This ammunition utilizes "low flash" powders to mitigate being blinded by bright muzzle flash. This ammunition is built specifically for defense purposes. This ammunition is new production, non-corrosive, boxer primed, in reloadable brass cases.
