This matched die set ensures consistent case preparation and accurate bullet seating for improved ammunition performance.

What Makes This Different

Hornady's Custom Grade dies feature heat-treated steel construction with hand-polished interiors that reduce case wear and extend brass life beyond standard reloading dies. The full-length sizing die includes an expander ball for consistent neck tension, while the seating die incorporates a built-in roll crimp feature. These dies maintain tighter tolerances than factory ammunition specifications, producing more consistent velocities and improved accuracy.

Key Features

• Full-length sizing die with polished interior reduces case stretching and work hardening

These dies handle both steel and brass 7.62x39mm cases effectively, making them suitable for reloading surplus military brass or new commercial cases. The sizing die returns fired cases to SAAMI specifications while the seating die allows precise control over overall cartridge length and crimp tension. Competitive shooters benefit from the consistent ammunition these dies produce, while hunters appreciate the improved accuracy potential over factory loads.
