Hornady Black 5.56 NATO 75gr InterLock HD SBR 200ct Case

Hornady Black 5.56 NATO 75-grain InterLock HD SBR is designed specifically for short-barreled AR-pattern rifles where standard 5.56 loads give up terminal performance. The InterLock HD SBR bullet uses a bonded lead core, thick jacket, and InterLock ring to hold the core and jacket together through intermediate barriers, delivering controlled expansion and deep penetration even at reduced SBR velocities.

The 75-grain weight favors faster twist barrels (1:7 or 1:8) common on modern carbines. Loaded for consistent function through gas-operated actions and paired with Hornady's match-grade case prep, this is a capable home defense and duty option for 10.5-inch to 16-inch AR-15s. The 200-round case supports departmental training rotations and defensive load verification.
