Winchester Defender 40 S&W 180gr Bonded JHP Ammo - 20 Rounds

The Winchester Defender S40SWPDB1 delivers reliable terminal performance with bonded jacket hollow point construction engineered for consistent expansion and deep penetration. This 180-grain 40 S&W ammunition combines Winchester's proven bonding technology with optimized powder charges for duty-grade reliability.

What Makes This Different

The bonded jacket design prevents core separation during expansion, maintaining bullet weight retention that exceeds 95% in ballistic testing. Unlike standard hollow points that can fragment or fail to expand, the Defender's bonded construction ensures predictable performance through intermediate barriers including heavy clothing, wallboard, and automotive glass. The 180-grain bullet weight provides optimal momentum transfer while maintaining manageable recoil in service pistols.

Key Features

• Bonded jacket hollow point prevents core-jacket separation for maximum weight retention
• 180-grain bullet weight optimized for 40 S&W ballistics and penetration depth
• Nickel-plated brass cases resist corrosion and ensure smooth feeding
• Low-flash powder reduces muzzle signature in low-light situations
• Consistent 1000 fps muzzle velocity from 4-inch barrel
• 20-round boxes packaged in 10-box cases for bulk purchasing
• Compatible with all 40 S&W chambered firearms

Field testing demonstrates reliable expansion across velocity ranges from 850-1100 fps, with penetration depths consistently meeting FBI protocol standards of 12-18 inches in calibrated ballistic gelatin. The ammunition functions reliably in full-size service pistols, compact carry guns, and subcompact platforms. Temperature stability maintains consistent performance from -20°F to 140°F storage conditions.
