Factory Crimp Die Cal. 30-30 Win LEE
Lee Factory Crimp Die for .30/30 Winchester caliber cartridges.
This precision-engineered crimp die is specifically designed to deliver an optimal and consistent crimp on your metallic cartridges, ensuring superior bullet retention and enhanced ballistic performance.
Unlike conventional dies, this Factory Crimp Die firmly secures the projectile to the case mouth without causing any deformation or damage to the brass casing, preserving the integrity of your reloads.
Featuring a specialized crimping collar, the die compresses the case mouth into the bullets crimp groove, providing a robust mechanical lock that prevents bullet setback during feeding and recoil in semi-automatic and lever-action firearms.
Extensive ballistic testing conducted by Lee has demonstrated that utilizing a Factory Crimp Die results in a more uniform pressure curve throughout the firing cycle, which directly contributes to improved shot-to-shot consistency and overall accuracy.
Moreover, this die enhances precision even with bullets lacking a factory crimp groove, by establishing a reliable crimp interface that stabilizes the bullet before ignition.
The enhanced crimping process increases the initial resistance pressure, requiring a higher force for the bullet to begin moving, which stabilizes internal ballistics and reduces velocity variations between rounds.
This elevated initial pressure ensures a smoother and more predictable pressure curve, minimizing velocity spreads and improving long-range shot placement.
Recommended primarily for use with semi-automatic and lever-action rifles chambered in .30/30 Winchester, where consistent bullet retention is critical for reliable cycling and performance.
Please note: this Factory Crimp Die does not include a shell holder and is compatible with reloading presses accepting the standard 7/8"-14 thread pattern.
Constructed from high-grade steel, this die offers durability and precision machining for long-lasting use in metallic and semi-metallic cartridge reloading applications.
Packaged in a protective plastic case for safe storage and transport.
