.300 Blackout New Brass
New .300 AAC Blackout brass gives reloaders an unfired, factory-fresh starting point for subsonic suppressed and supersonic AR loads. At Capital Cartridge, new .300 AAC Blackout cases deliver uniform wall thickness and case capacity, which is why many handloaders start with new brass when working up accurate loads. A cartridge built around handloading flexibility.
New brass also offers the longest reloading life, since it hasn't been fired or worked yet. Bulk quantities are available for .300 AAC Blackout reloaders who load in volume.
