Description
The Frontier Cartridge FR410 is a 300 Blackout subsonic load built around a heavy 208-grain Full Metal Jacket bullet, designed for quiet, reliable performance from suppressed and unsuppressed 300 AAC Blackout rifles. Frontier Cartridge is Hornady’s American-made ammunition line, and this FR410 offering packages the components in brass cases with boxer primers and non-steel-core FMJ projectiles for clean feeding and suppressor-friendly cycling.
Loaded as a true subsonic round, the FR410 leaves the muzzle at approximately 1025 fps, keeping the projectile below the speed of sound for reduced blast and signature when fired through a suppressor. The heavy 208 gr FMJ bullet stabilizes well from standard 300 Blackout twist rates and delivers consistent performance for plinking, target practice, training drills, and hunting applications where a quiet, hard-hitting projectile is desired.
Each box of 20 rounds is factory-loaded to consistent specifications. A full case of 200 rounds contains ten 20-round boxes, making the case format an economical choice for high-volume shooters and training sessions.
Your purchase options:
- Box – 20 Rounds
