Frontier Cartridge Frontier, 300 Blackout, 208 Grain, Subsonic, 20 Round Box

Product Description

Frontier 300 Blackout 208 grain subsonic ammunition is engineered for shooters who demand reliable, quiet performance from their suppressed rifles. This 20-round box contains full metal jacket rounds optimized for subsonic velocity, making them perfect for hearing-protection-free shooting and tactical training.

Specifications & Performance

Each box contains 20 rounds of .300 Blackout ammunition loaded to subsonic specifications. The 208-grain projectile delivers consistent ballistics and controlled recoil. Additionally, the full metal jacket construction ensures reliable feeding and consistent performance across suppressed and unsuppressed platforms.

Moreover, subsonic loads reduce report and felt recoil compared to supersonic alternatives. Therefore, this Frontier ammunition is ideal for home defense, hunting, and tactical range training where noise control matters. The heavier grain weight provides excellent velocity stability at subsonic speeds.

Who Should Buy This Ammunition?

This ammunition suits suppressed .300 Blackout rifle owners and shooters prioritizing quiet performance. Furthermore, competitive shooters and range trainers benefit from the consistent ballistics and reduced noise. Competition shooters, hunters, and home defense-minded gun owners all appreciate subsonic loads for their reliability and controlled operation.

In addition, Frontier 300 Blackout ammunition works reliably in both AR-platform rifles and bolt-action firearms chambered in .300 Blackout. The full metal jacket design feeds smoothly and ejects cleanly, minimizing maintenance between sessions.

Range Testing & Real-World Use

Subsonic ammunition excels when paired with sound suppressors on suppressed rifles. Additionally, the 208-grain weight maintains velocity consistency, which reduces point-of-aim shift compared to lighter loads. Consequently, shooters experience predictable accuracy from shot to shot during range sessions and training courses.
