Lee Factory Crimp Die for 7x57 Mauser caliber cartridges.
This precision-engineered crimp die is specifically designed to provide an optimal and consistent crimp on your metallic and semi-metallic cartridges, ensuring superior bullet retention and enhanced ballistic performance.
Unlike standard dies, this Factory Crimp Die firmly secures the projectile to the case neck with exceptional grip, preventing bullet setback or movement during feeding and recoil without causing any deformation or damage to the brass case or its neck.
The die features a specialized crimping collar that compresses the case mouth precisely into the bullets crimp groove, delivering a secure and reliable hold that is critical for maintaining consistent internal ballistics and pressure curves.
Extensive testing by Lee has demonstrated that utilizing a Factory Crimp Die results in a more uniform pressure curve throughout the firing cycle, which directly translates into improved shot-to-shot accuracy and tighter groupings on target.
These tests also confirm that even projectiles lacking a dedicated crimp groove benefit significantly from the controlled crimp, achieving enhanced precision by minimizing bullet movement prior to ignition.
By increasing the initial bullet pull force, the crimp ensures that the cartridge maintains a higher and more consistent pressure threshold before the bullet begins to travel down the barrel, reducing velocity variations and improving overall ballistic consistency.
This die is highly recommended for use in semi-automatic and lever-action rifles, where reliable bullet retention is paramount to prevent feeding issues and maintain consistent chamber pressures.
Please note that the Shellholder is not included with this die and must be acquired separately.
Constructed from high-grade steel, this Factory Crimp Die is built for durability and long-lasting performance under rigorous reloading conditions.
Compatible with reloading presses that accept the standard 7/8"-14 thread size, ensuring broad compatibility with most Lee and other popular press models.
Packaged in a protective plastic case for secure storage and easy transport.
