Key Features

• 55-Grain Full Metal Jacket (FMJ) Bullet: The classic 55-grain weight offers a flat trajectory and manageable recoil, ideal for extended range sessions. The FMJ design, with its lead core encased in a copper alloy jacket, provides reliable feeding and is optimized for target shooting on paper or steel.
• High-Quality Brass Cases: Each cartridge features reloadable brass cases that ensure consistent powder burn and chamber pressure, contributing to the ammunition’s notable reliability and accuracy potential.
• Non-Corrosive Boxer Primers: Winchester utilizes non-corrosive Boxer primers in this load. This is a critical feature for firearm longevity, as it prevents corrosive salt deposits that can damage barrels and components, and the Boxer design facilitates easier reloading for handloaders.
• 200-Round Bulk Packaging: The bulk pack format offers significant value and convenience. It reduces the cost per round and minimizes packaging waste, allowing shooters to focus more on training and less on frequently opening small boxes.
• Manufactured to Consistent SAAMI Specifications: This ammunition is produced to the strict pressure and dimensional standards set by the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI). This guarantees safe operation in firearms chambered for .223 Remington and 5.56 NATO (always consult your firearm’s manual).
• Winchester’s Reputation for Reliability: Behind every round is over 150 years of Winchester’s ammunition manufacturing expertise, ensuring each cartridge meets a high standard for performance and dependable ignition.
