Factory Crimp Die Caliber 6MM REM LEE for Reloading and Precision Shooting
Lee Factory Crimp Die for 7x57 Mauser caliber cartridges, expertly engineered to deliver an optimal crimping solution for precision handloading and metallic cartridge assembly.
This specialized crimp die is meticulously designed to apply a consistent and reliable factory crimp, ensuring the bullet is firmly secured to the case neck without causing any deformation or damage to the brass casing or the bullet itself.
Featuring an advanced collet mechanism, the die compresses the case mouth precisely into the bullets crimp groove, providing a secure and uniform hold that surpasses conventional crimping methods. This enhanced retention is critical for maintaining consistent internal ballistics and reliable feeding in semi-automatic and lever-action firearms.
Extensive testing conducted by Lee Precision confirms that utilizing the Factory Crimp Die results in a more uniform chamber pressure curve, which directly contributes to improved shot-to-shot consistency and enhanced projectile accuracy. This is particularly beneficial for reloaders seeking to optimize ballistic performance in competitive shooting or hunting scenarios.
Notably, the dies effectiveness extends even to bullets lacking a factory crimp groove, demonstrating measurable improvements in precision due to the increased bullet retention force.
The superior crimping action elevates the initial bullet release pressure, requiring a higher threshold before the projectile begins to move down the barrel. This elevated bullet jump pressure stabilizes the internal pressure curve, reducing velocity variation and promoting tighter groupings on target.
Recommended primarily for use with semi-automatic rifles and lever-action firearms, this die ensures reliable cartridge feeding and consistent ballistic performance under rapid-fire conditions.
Please note: the Shellholder is not included with this die and must be sourced separately.
Constructed from hardened steel for durability and long service life, this die is compatible with reloading presses that accept the standard 7/8"-14 thread size.
Packaged in a protective plastic case to safeguard the die during storage and transport.
