Winchester Super X .223 Rem 55gr JSP Ammo - 20rd Box/10 Case

The Winchester Super X .223 Remington ammunition delivers proven terminal performance with 55-grain jacketed soft point bullets engineered for controlled expansion and reliable feeding. This factory-loaded ammunition provides consistent accuracy and stopping power across multiple shooting applications.

What Makes This Different

Winchester's jacketed soft point design combines the penetration of a full metal jacket with the expansion characteristics of a hollow point. The exposed lead tip initiates reliable expansion upon impact while the copper jacket maintains structural integrity during feeding and flight. This dual-purpose construction outperforms basic FMJ rounds in terminal effectiveness while maintaining the reliability required for semi-automatic platforms.

Key Features

• 55-grain jacketed soft point bullets for controlled expansion
• Brass cases with boxer primers for reliable ignition
• Factory-loaded to SAAMI specifications for consistent performance
• Compatible with .223 Remington and 5.56 NATO chambers
• Clean-burning powder reduces fouling and maintenance
• Bulk case packaging with 200 total rounds (10 boxes of 20)
• Crimped case mouths prevent bullet setback during feeding

Field testing demonstrates consistent 2-3 inch groups at 100 yards from quality rifles with proper optics. The moderate recoil and muzzle flash make this load suitable for extended range sessions, varmint hunting, and tactical applications. The soft point construction provides enhanced terminal ballistics compared to military surplus ammunition while maintaining reliable cycling in AR-15 platforms and bolt-action rifles.
