Factory Crimp Die Cal. 300 Weatherby Mag LEE
Lee Factory Crimp Die for .222 Remington caliber cartridges.
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 standard dies, this Factory Crimp Die firmly secures the projectile to the case neck with exceptional grip strength, without causing any deformation or damage to the brass casing or bullet seating depth.
The die features a specialized crimping collar that compresses the case mouth into the bullets crimp groove, delivering a reliable and repeatable crimp that maintains cartridge integrity during feeding and cycling.
Extensive testing conducted by Lee Precision demonstrates that utilizing a Factory Crimp Die produces a more uniform chamber pressure curve, which directly translates into improved shot-to-shot consistency and enhanced accuracy on the range.
Notably, this die improves precision even with bullets lacking a factory crimp groove, by providing a controlled and secure bullet hold that minimizes bullet movement under recoil and firing stresses.
The application of a proper crimp increases the initial resistance to bullet movement, requiring a higher bullet jump pressure threshold before the projectile begins to travel down the barrel, thereby stabilizing internal ballistics.
This elevated initial crimp pressure ensures a smoother and more predictable pressure curve, reducing velocity variations and enhancing overall cartridge performance.
Recommended for use in semi-automatic rifles and lever-action firearms, where consistent bullet retention is critical for reliable feeding and cycling.
Please note: Shellholder is not included with this die.
Constructed from durable, high-grade steel for long-lasting use and precision.
Compatible with reloading presses that accept the standard 7/8"-14 thread size.
Supplied in a protective plastic storage case to safeguard the die when not in use.
