Processed 300 AAC Blackout Brass

Processed 300 AAC Blackout Brass

Processed 300 AAC Blackout brass is sourced from once-fired range brass of both military and commercial pedigree, including converted 223 Remington cases, and is fully reconditioned to SAAMI 300 AAC Blackout specifications. This brass undergoes rigorous cleaning, resizing, swaging, and trimming processes, ensuring it is ready to load straight out of the bag—no additional case prep required.

This is the same brass we trust in our own rifles. Whether you shoot a bolt-action or an AR-15, this brass performs reliably across all platforms. It’s a popular choice among reloaders looking for a cost-effective solution without sacrificing quality. On average, you can expect between two and six reloads per cartridge under normal use, especially when annealed at proper intervals. Our brass is sourced directly from indoor and outdoor ranges that prohibit reloads, ensuring that all brass is truly once-fired and not subject to the inconsistencies of multiple firing cycles.

Every lot of our processed 300 AAC Blackout brass is filled to 101% to ensure you get extra cases (10 additional per 1000 count) and is packed in sealed, heavy-duty, retail-quality bags ideal for long-term storage. These bags help maintain the integrity of the brass while keeping moisture and debris out. For those aiming for even more consistency, our brass also serves as an excellent starting point for advanced reloaders seeking to perform match-grade final prep work.

We recommend applying a light chamfer to the case mouth for smoother bullet seating. Please note that neck tension is not preset and must be applied by the end user. This is easily accomplished using an “M Die” or your preferred method of neck expanding. Choosing processed brass over new brass offers a savings of over 50% compared to new Hornady cases, making it an economical choice for high-volume reloaders and competition shooters alike.
