8.6 Blackout Rifle Brass 100/Box

Alpha Munitions 8.6 Blackout rifle brass gives reloaders the foundation for building ammunition for one of modern shooting's most versatile cartridges. Built on a 6.5 Creedmoor case necked up to .338 caliber, 8.6 Blackout brass is engineered for shooters who want supersonic performance with heavy bullets or subsonic capability from the same platform—all without changing your rifle. If you run a 308 Winchester receiver, a barrel swap is all it takes to unlock this cartridge's potential. This 100-count box of unprimed brass is your starting point for handloading everything from 160–225 grain supersonic loads to 285–350 grain subsonic rounds.

Alpha Munitions doesn't cut corners on case quality. Their OCD (Optimized Case Design) head technology is built into every case to extend primer pocket life and overall case longevity, even when you're pushing pressure and velocity. That durability matters when you're investing time and precision into custom ammunition. The brass accepts large rifle primers, keeping your reloading setup straightforward and your component sourcing simple.

Each case arrives individually nestled in a plastic flip-top box with protective foam, so your brass shows up ready to clean, inspect, and load. Whether you're building subsonic rounds for suppressed shooting, hunting loads, or long-range supersonic precision ammo, starting with quality brass from Alpha Munitions sets you up for consistency and reliability downrange.
