Factory Crimp Die Cal. 375 H&H LEE
Lee Factory Crimp Die for .375 H&H Caliber Ammunition Reloading.
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.
Utilizing advanced crimping technology, this die firmly secures the projectile to the case neck with greater force than conventional dies, without causing any deformation or damage to the brass casing or the bullet itself.
The die features a specialized collet mechanism that compresses the case mouth precisely into the bullets crimp groove, providing a reliable and repeatable crimp that withstands the rigors of semi-automatic and lever-action firearms.
Extensive testing conducted by Lee has demonstrated that employing the Factory Crimp Die results in a more uniform pressure curve during ignition, which directly translates into improved shot-to-shot consistency and enhanced accuracy downrange.
Notably, this die also improves accuracy with bullets lacking a factory crimp groove, by applying a controlled crimp that stabilizes the bullet seating and reduces initial bullet movement upon firing.
The enhanced crimping process increases the initial resistance pressure required to unseat the bullet, thereby promoting a smoother and more predictable internal ballistics profile with reduced velocity variance.
This higher initial crimp pressure is critical for maintaining consistent muzzle velocities and achieving tighter groupings, especially in high-powered cartridges such as the .375 H&H Magnum.
Recommended primarily for use in semi-automatic rifles and lever-action firearms, this die ensures reliable feeding and cycling by preventing bullet setback or movement during the feeding cycle.
Please note that the Shellholder is not included and must be sourced separately to match your specific reloading press model.
Constructed from hardened steel for long-lasting durability and precision, this crimp die is compatible with reloading presses accepting the standard 7/8"-14 thread size.
Packaged in a protective plastic case to safeguard the die from damage and contamination during storage and transport.
