Lyman Pro Die Pack 300 Blackout 3-Die Set Reloading Dies

The Lyman 7701028 Pro Die Pack delivers precision reloading capabilities for 300 Blackout cartridges with professional-grade construction. This three-die set enables consistent ammunition production for both subsonic and supersonic loads. Engineered with hardened steel construction, these dies maintain dimensional accuracy through thousands of reloading cycles.

What Makes This Different

The Pro Die Pack features Lyman's advanced die geometry that reduces case working and extends brass life compared to standard reloading dies. Each die incorporates precision-ground surfaces and tight tolerances that ensure consistent bullet seating depth and neck tension. The carbide sizing ring eliminates the need for case lubrication during resizing operations, streamlining the reloading process while preventing stuck cases.
