Winchester Defender Ammunition in 40 S&W, 180 grain bonded jacketed hollow point rounds is purpose-built for personal defense when reliability and stopping power matter most. The Defender line delivers what serious shooters depend on: engineered ammunition backed by FBI testing standards and real-world terminal performance. Each round in this 20-round box benefits from Winchester's bonded-core construction—a manufacturing process that welds the jacket to the lead core for consistent expansion and penetration that won't let you down.
The 180-grain bonded hollow point design is the sweet spot for 40 S&W defensive carry. At 1140 fps muzzle velocity and 476 ft-lbs of energy, this round delivers the velocity needed for reliable expansion without excessive overpenetration. The hollow point cavity and jacket-to-core bond work together to achieve the 1.5x expansion that makes Defender ammunition effective in real-world defensive scenarios—not just on paper. Whether you're loading your carry gun, stocking a duty weapon, or building a reliable home-defense supply, Winchester's defensive ammunition is manufactured to standards that match the seriousness of the mission.
Available in convenient 20-round boxes, Winchester Defender ammunition is ready for shooters who choose proven engineering over marketing hype. This is ammunition designed to function flawlessly in your 40 S&W platform and perform when it counts.
