Details

Black Hills loads this 8.6 Blackout round with a 300-grain Sierra MatchKing bullet specifically for subsonic, suppressed shooting, giving precision-focused shooters a quiet, match-grade load for their AR-10 or bolt-action 8.6 Blackout rifle.

Features:

300-grain Sierra MatchKing hollow point boat-tail bullet, a proven match-grade projectile
Loaded to stay subsonic for quiet, suppressed shooting with no sonic crack
8.6 Blackout's fast-twist barrel requirement stabilizes this heavy bullet for tight groups
Muzzle energy exceeding 800 ft-lbs even at subsonic velocity
Consistent brass and powder charges for Black Hills' signature lot-to-lot accuracy
Q headstamped brass
Box of 20 rounds

The 8.6 Blackout cartridge was purpose-built to fire heavy, .338-caliber-class bullets at subsonic velocities from a short, suppressor-friendly rifle, and this 300-grain SMK load represents the precision end of that spectrum, favored for quiet range work, load confirmation, and dialing in a suppressed rifle's true point of impact.

Black Hills Ammunition has built a reputation for match-grade consistency since 1985, and its early adoption of emerging cartridges like 8.6 Blackout reflects the same component-driven, small-batch quality control the company is known for across its entire lineup. That attention to detail is why competitive shooters and precision hunters keep coming back to the brand.
