The Winchester S45CPDB Defender delivers maximum stopping power for 45 Colt firearms with its 225-grain bonded jacket hollow point design. This premium defensive ammunition combines controlled expansion with deep penetration to neutralize threats effectively.
What Makes This Different
The bonded jacket construction prevents core separation during expansion, maintaining weight retention above 95% while creating devastating wound channels. Unlike standard hollow points that can fragment or fail to expand through heavy clothing, the Defender's bonded design ensures consistent performance across various barrier materials. The 225-grain projectile weight provides superior momentum transfer compared to lighter defensive loads.
