Factory Crimp Die Caliber 7 Remington Magnum for Reloading and Precision Shooting
Lee Factory Crimp Die for 7mm Remington Magnum caliber cartridges.
This precision-engineered crimp die is specifically designed to deliver an optimal and consistent crimp on your metallic and semi-metallic cartridges, ensuring superior bullet retention and enhanced ballistic performance.
Featuring a robust crimping mechanism, this die firmly secures the projectile to the case neck more effectively than conventional dies, without causing any deformation or damage to the brass case or its neck.
The die incorporates a specialized crimping groove that tightly compresses the case mouth into the bullet cannelure, providing a secure and reliable bullet hold that is essential for maintaining consistent chamber pressures and improving overall accuracy.
Extensive testing conducted by Lee has demonstrated that utilizing the Factory Crimp Die results in a more uniform pressure curve during firing, which directly contributes to enhanced shot-to-shot consistency and improved projectile precision.
Notably, this crimp die delivers measurable accuracy improvements even with bullets lacking a factory cannelure, by increasing the initial resistance to bullet movement and stabilizing internal ballistics.
The enhanced crimping effect elevates the initial bullet release pressure, ensuring a more stable and predictable pressure curve, which reduces velocity variations and optimizes terminal performance.
Recommended primarily for use in semi-automatic and lever-action rifles, where secure bullet retention is critical to prevent bullet setback or feeding issues during cycling.
Please note that the Shellholder is not included and must be sourced separately.
Constructed from high-grade steel for durability and long service life under rigorous reloading conditions.
Compatible with reloading presses that accept the standard 7/8"-14 thread size.
Supplied in a protective plastic storage case for safe handling and easy organization within your reloading bench setup.
