Hornady Black HD SBR | 5.56 Nato | 75gr | Interlock - 81296

Hornady BLACK 5.56 NATO 75gr InterLock HD SBR (MPN: 81296)

The Hornady BLACK (MPN: 81296) is not just another 5.56 load; it is a purpose-built solution for one of the most challenging platforms in modern shooting: the Short-Barreled Rifle (SBR). While standard duty ammunition often suffers from excessive muzzle flash, erratic cycling, and poor terminal performance when fired from short barrels, the Hornady BLACK 75-grain InterLock® HD is optimized specifically to excel in suppressed and unsuppressed carbines.

Optimized for the SBR

At the core of this load is a specialized propellant choice designed to reach peak pressure quickly. This ensures that you get maximum velocity out of 10.5" to 14.5" barrels while significantly reducing the blinding muzzle flash typically associated with unburned powder exiting a short bore. Whether you are running a suppressor or a flash hider, the BLACK line ensures your follow-up shots are fast and your sight picture remains clear.

The InterLock® HD Bullet

The 75-grain InterLock® HD (Heavy Duty) projectile is engineered for devastating terminal performance. Unlike standard FMJs or thin-jacketed match bullets, the InterLock® features a mechanical taper and a locked lead core. This design ensures that the bullet expands rapidly upon impact but maintains the structural integrity required to penetrate deep into the target, even after encountering heavy clothing or light barriers.

Key Features & Benefits

• SBR Optimized: Specially formulated to provide superior performance in short-barreled rifles, reducing flash and sound signature.

• InterLock® Technology: A core-locking groove ensures the jacket and lead core remain one piece during expansion for maximum weight retention.

• Versatile Cycling: Engineered to cycle reliably in a wide variety of gas systems, including direct impingement and piston-driven AR-15s.

• Hornady Quality: Built with premium Hornady cases and high-sensitivity primers for "match-grade" consistency in a duty-ready round

The Hornady BLACK 75gr InterLock HD is the definitive choice for the professional or enthusiast running a suppressed AR-15 or SBR. It bridges the gap between precision-match ballistics and rugged duty performance, ensuring that your compact rifle performs with full-sized authority.
