Atomic Ammunition Subsonic .223 Remington 77 grain Boat Tail Hollow Point Brass Cased Rifle Ammo 100 Rounds

Atomic Ammunition Subsonic .223 Remington 77 grain Boat Tail Hollow Point Brass Cased Rifle Ammo 100 Rounds. 223 Rem 77gr subsonic ammo is built for suppressed AR-15 training and quiet close-range practice. The hollow point boat tail load stays below the sound barrier to cut the crack of standard .223 while preserving practical accuracy for low-noise rifle work. Subsonic .223 is a niche load with a specific purpose: maximum noise reduction on the AR-15 platform. At 1050 fps with a suppressor you get hearing-safe shooting (under 125 dB) without the punishing crack of standard 5.56. The 77gr HP BT maintains good accuracy at close range (inside 100 yards). Note: subsonic .223 will not reliably cycle semi-auto gas systems this is a bolt-action or single-shot load. For shooters with bolt-action .223s or AR-15s with suppressor-optimized uppers its a uniquely quiet training experience. Loaded with new brass cases precision-weighed powder charges and 77gr HP BT projectiles. Hand-inspected to Atomics standards.
