338 Spectre - 300 gr Subsonic Maker - 20 CT

The .338 Spectre is an advanced cartridge designed to bridge the gap between traditional pistol calibers and rifle cartridges for AR-15 platforms. Sharing the same rim size as the Remington 6.8 SPC, this cartridge offers seamless compatibility with OEM bolts, making it a versatile option for those seeking both power and adaptability.

With ballistics that rival the .357 Maximum, the .338 Spectre is a highly capable cartridge for hunting, silhouette shooting, and even small game. Its .338 caliber bullets offer a wide range of projectile choices, from lighter 160-grain to heavier 300-grain options, allowing for customizable performance. The round is especially effective when paired with suppressors designed for 9mm, offering quiet, subsonic firepower without the need for equipment modifications.

In a 16-inch carbine, the .338 Spectre excels in both supersonic and subsonic roles. Supersonic loads can launch a 180-grain bullet at 1,800 ft/sec, delivering nearly 1,300 ft-lbs of energy, making it an excellent choice for tactical and hunting applications. On the other end of the spectrum, when loaded with a 300-grain bullet at subsonic velocities, the cartridge delivers 720 ft-lbs of energy, outperforming popular options like the 9mm Parabellum and .300 AAC Blackout.

This combination of versatility, power, and adaptability makes the .338 Spectre an outstanding cartridge for both suppressed and unsuppressed use in AR-15 platforms.
