Remington 300 Aac 120gr Copper - Core-lokt Hp 20rd 10bx/cs

The Remington 300 AAC 120gr Copper Core-Lokt HP ammunition is purpose-built for short-barreled rifles and suppressed platforms where subsonic or near-subsonic performance is critical. Designed for law enforcement tactical operations, military applications, and civilian precision hunting, this cartridge delivers reliable expansion and consistent velocity in the .300 AAC Blackout platform. Each box contains 20 rounds, with 10 boxes per case (200 rounds total), making bulk procurement practical for range training and duty use.

The 120-grain Copper Core-Lokt hollow point projectile employs Remington's proven solid-copper construction, which ensures controlled expansion and superior weight retention through intermediate barriers such as drywall, light body armor, or vehicle barriers. The hollow point design promotes rapid energy transfer to the target while minimizing over-penetration—a critical consideration in close-quarters combat environments and urban operations where backdrop safety is paramount. This ammunition is optimized for subsonic performance in 7.5-inch to 10.5-inch barrel lengths, maintaining velocity stability and terminal ballistics consistency that shooters depend on in high-stress situations.

Operators and duty teams leveraging suppressed AR-15 platforms in the .300 Blackout caliber will find this load ideal for both subsonic and transonic applications. Law enforcement agencies conducting dynamic entry operations, military special operations units, and civilian shooters pursuing precision hunting benefit from the consistent ballistics and terminal performance Remington's Core-Lokt line has delivered for decades. Compatibility is straightforward—any standard .300 AAC Blackout chamber will accept this ammunition; however, subsonic velocity (typically 1,050–1,150 feet per second) is optimized for barrels in the 7.5-inch to 10.5-inch range and benefits from suppressor use for maximum velocity stability and sound signature reduction.
