Lee Factory Crimp Die for .458 Winchester Magnum caliber ammunition.
This precision-engineered crimp die is specifically designed to provide an optimal and consistent crimp on your metallic cartridges, ensuring superior bullet retention and enhanced ballistic performance.
Unlike conventional crimping tools, this die firmly secures the projectile to the case neck without causing any deformation or damage to the brass casing, preserving the integrity of your reloads and extending case life.
The die features a specialized crimping collar that compresses the case mouth into the bullets crimp groove, delivering a reliable and repeatable crimp that prevents bullet setback during feeding and recoil, which is critical for maintaining consistent chamber pressures.
Extensive testing conducted by Lee Precision has demonstrated that utilizing a Factory Crimp Die results in a more uniform pressure curve throughout the firing cycle, directly contributing to improved shot-to-shot accuracy and velocity consistency.
These tests also confirm that even bullets lacking a factory crimp groove benefit from the enhanced bullet retention and precision provided by this die, making it an indispensable tool for handloaders focused on precision shooting.
The enhanced crimping process increases the initial resistance to bullet movement, requiring a higher initial pressure to unseat the projectile. This elevated bullet pull force stabilizes internal ballistics by reducing pressure spikes and minimizing velocity variations.
Such a controlled pressure curve is especially advantageous when reloading for semi-automatic and lever-action rifles, where reliable feeding and consistent chamber pressures are paramount for both safety and performance.
Please note, this Factory Crimp Die does not include a shellholder and is compatible with reloading presses that accept the standard 7/8"-14 thread size.
Constructed from high-grade steel, this die offers durability and long-lasting precision for your reloading bench.
Packaged in a protective plastic case to ensure safe storage and easy transport.
