The Mighty Armory GOLD MATCH 300 Blackout is a Precision Match Series sizing, decapping die that offers FULL LENGTH, concentric sizing to SAAMI spec standards with correct bullet tension, to ensure safety, reliability, accuracy and ease of use. The extended, full length size area helps to prevent under-sizing or over-sizing at the neck, shoulder and base. This will result in proper case pressure, cleaner burning powder, reliable chambering and extraction, absolute accuracy, and your brass will last longer for more reloads.
Mighty Armory state-of-the-art sizing die designs are precision machined to tight tolerances, ensuring consistent and uniform sizing and concentricity of the case.
Full length sizing is recommended for all rifle cases. Neck sizing can lead to overexpanded cases and reduce reloading times as it weakens the brass. A hard, smooth sizing surface that is consistent in sizing, especially head-spacing is of the utmost importance.
RESULTS WILL BE BETTER THAN FACTORY LOADS
