Berry’s 300 Blackout 220gr SP

Berry’s 300 Blackout 220gr SP is a plated bullet component engineered specifically for handloaders building subsonic ammunition for the 300 AAC Blackout platform. This 220-grain Spire Point (SP) projectile offers excellent mass and flight stability in short-barrel, suppressed, or specialty builds. Sold as a bullet component only—not loaded ammunition—it is ideal for precision subsonic applications including suppressed shooting, tactical training, and quiet hunting loads.

The bullet features a swaged lead core electroplated with copper to its final weight, then re-struck for dimensional consistency. At 1.350″ in bullet overall length and intended for cartridge overall lengths around 2.150″, it seats correctly in 300 AAC Blackout cases and feeds reliably in AR-15 style rifles and compatible bolt-action platforms. Its full copper plating eliminates exposed lead, supporting clean indoor range use and minimizing barrel fouling during extended suppressed fire.

The Spire Point design enhances ballistic stability and accuracy in subsonic velocities, with optimized tapering for minimal drag. It performs best in barrels with a fast twist rate—Berry’s recommends a 1:7″ twist for up to 1,300 fps, or 1:5″ twist for stability below 1,000 fps. This flexibility supports load tuning for ultra-quiet performance or maximum terminal energy within safe velocity thresholds. The bullet’s mass contributes to superior momentum and energy transfer on impact, making it suitable for quiet hunting or personal defense where suppressed functionality is essential.

Handloaders must remain within Berry’s published maximum velocities to prevent core-jacket separation and maintain accuracy. Load data for jacketed or cast bullets of identical weight and shape may be used. Crimping options include taper or roll crimp, though over-crimping should be avoided to preserve plating integrity. The long bullet profile and weight demand careful attention to seating depth and case capacity during load development.

Berry’s 300 Blackout 220gr SP offers reloaders a specialized, clean-shooting, and reliable option for crafting heavy subsonic rounds. Its plated construction, precision forming, and aerodynamic profile make it a top-tier choice for suppressed 300 AAC Blackout rifles. Whether for tactical drills, quiet hunting, or stealthy range sessions, this bullet delivers smooth cycling, clean bore conditions, and controlled terminal results in subsonic applications.
