Winchester Super Suppressed 300 AAC Blackout Ammunition 200 Grain Full Metal Jacket - SUP300BLK

The Winchester Super Suppressed 300 AAC Blackout Ammunition is purpose-built for quiet precision. Featuring a 200 Grain Full Metal Jacket bullet, this subsonic round is optimized for use with suppressors, making it ideal for discreet range training and tactical scenarios. Designed and manufactured in the USA, it reflects Winchester?s commitment to quality, innovation, and shooter performance.

This ammunition offers a muzzle velocity of 1060 fps and muzzle energy of 499 ft-lbs, delivering effective ballistic performance while keeping noise levels low. The FMJ design ensures reliable feeding, reduced bore fouling, and consistent accuracy ? essential for high-volume shooting sessions. Paired with a suppressor, this round excels in stealth-focused applications.

Packaged in bulk options for added cost-efficiency, and built with reloadable brass casings and non-corrosive Boxer primers, this is a top-tier choice for professionals and enthusiasts alike who demand reliability and quiet performance in every shot.
