Gorilla 300blk 220gr Subsonic 20/200

The Gorilla 300 Blackout 220 Grain Subsonic ammunition delivers reliable suppressed-fire performance from a manufacturer known for precision reloading standards. Each round pairs a 220-grain Sierra Matchking bullet with once-fired Lake City military brass that has undergone Gorilla's proprietary cleaning and resizing process. At 1,030 feet per second, this subsonic load stays below the sound barrier in all standard 300 Blackout platforms, making it the choice for shooters prioritizing noise reduction without sacrificing accuracy.

The 220-grain Sierra Matchking projectile is engineered for consistent ballistics and tight shot grouping across distance. Subsonic velocity in 300 Blackout applications prevents the bullet from breaking the sound barrier, eliminating the supersonic crack that announces a shot—critical for tactical operations, law enforcement training, and suppressed-fire ranges where noise signature matters. The once-fired brass foundation ensures consistent chamber pressures and cartridge-to-cartridge uniformity while delivering substantial cost savings compared to new-manufacture ammunition without compromising reliability or accuracy standards Gorilla Ammunition is known for.

This 300 Blackout subsonic load serves precision rifle shooters, suppressed-fire trainers, and operators running short-barreled rifles (SBRs) in controlled environments where subsonic ballistics are required. The 20-round box format is standard for testing, load development, and training applications where shooters need to evaluate performance without committing to larger quantities. Gorilla's quality control on the Troop line ensures performance consistency across the string, supporting both accuracy validation on the range and reliable function in field conditions.
