Barnes Defense 12GA 2.75" 4 Buck 21 Pellet Shotshells - 5 Round Box

Barnes Defense 12-gauge shotshells deliver consistent terminal performance with precision-manufactured 4 buck shot for home defense and tactical applications. Each 2.75-inch shell contains 21 copper-plated pellets engineered for controlled expansion and deep penetration.

What Makes This Different

Barnes applies their proven bullet technology to shotgun ammunition, using copper-plated pellets that maintain structural integrity through barriers. Unlike standard lead shot that can deform on impact, these pellets retain their shape for consistent wound channels. The controlled pellet count of 21 rounds per shell provides optimal pattern density at defensive distances while reducing over-penetration risks compared to 00 buck loads.

Key Features

• 21 precision-manufactured 4 buck pellets per shell for balanced stopping power
• Copper-plated shot resists deformation through barriers and clothing
• 2.75-inch shells cycle reliably in all 12-gauge shotguns
• Consistent powder charge delivers uniform velocities shot to shot
• Low-flash powder reduces muzzle signature in low-light conditions
• High-quality hull construction prevents splits during extraction
• Sealed primer and crimp protect against moisture contamination

These shells excel in close-quarters defensive scenarios where controlled penetration matters. The 4 buck pellet size bridges the gap between smaller birdshot and larger 00 buck, providing sufficient energy transfer without excessive wall penetration. Law enforcement agencies appreciate the predictable ballistics and reduced ricochet potential. The copper plating maintains pellet integrity through auto glass and light barriers while delivering consistent patterns at ranges from 5 to 25 yards.
