Fiocchi Hyperformance SBR 300 Blackout 125gr SST

Purpose-Built for Short Barrels

Fiocchi Hyperformance SBR ammunition represents a thoughtful approach to a real problem: standard rifle ammunition often underperforms in short-barreled platforms. This load addresses that challenge head-on.

Ballistic Design

• Bullet: 125-grain Super Shock Tip (SST) for rapid, consistent expansion
• Velocity: Approximately 2,250 feet per second from test barrels
• Powder: Proprietary blend engineered for complete combustion
• Optimization: Designed for barrels ranging from 7.5 to 11.5 inches

Performance Features

The ammunition's powder selection delivers 100 percent burn, which means more energy reaches the target and less is wasted as unburned powder. This translates to reduced muzzle flash—a significant advantage in tactical environments or when using night vision equipment.

The diminished report makes this load more pleasant to shoot, particularly in enclosed spaces or when hearing protection is limited. Equally important, the ammunition is fully compatible with sound suppressors, making it an excellent choice for those running suppressed short-barreled rifles or pistols.

Practical Application

Whether you own a short-barreled rifle, patrol carbine, or arm-brace pistol, this ammunition delivers the ballistic and terminal performance you expect. The 125-grain projectile strikes a balance between velocity and energy retention, making it suitable for both training and defensive applications.

Each round reflects Fiocchi's commitment to precision manufacturing and consistent quality control.
