The Winchester S45PDB Defender delivers consistent terminal performance through its bonded jacket hollow point design, engineered specifically for personal protection applications. This 230-grain 45 ACP cartridge maintains bullet integrity during expansion while maximizing stopping power.
What Makes This Different
The bonded jacket construction prevents core separation that commonly occurs with standard hollow points during barrier penetration. Winchester's bonded process fuses the lead core to the copper jacket at the molecular level, ensuring the bullet retains 95% of its weight even after passing through intermediate barriers. This translates to deeper, more consistent penetration compared to conventional JHP designs that may fragment prematurely.
Key Features
- 230-grain bonded jacket hollow point for maximum weight retention
- Optimized for 12-16 inches FBI protocol penetration depth
- Nickel-plated brass cases resist corrosion and aid extraction
- Low-flash powder reduces muzzle signature in low-light conditions
- Consistent 850 fps muzzle velocity from 5-inch test barrel
- 20 rounds per box, 10 boxes per case (200 total rounds)
- Compatible with all 45 ACP chambered firearms
Field testing demonstrates reliable expansion across various barrel lengths while maintaining structural integrity through common barriers including heavy clothing, wallboard, and automotive glass. The cartridge functions reliably in both full-size and compact 45 ACP platforms, making it suitable for duty carry, home defense, and concealed carry applications. Temperature stability ensures consistent performance from -20°F to +125°F.
