Factory Crimp Die Caliber 375 Winchester LEE for Reloading and Precision Shooting
Lee Factory Crimp Die for .375 Winchester Caliber
This precision-engineered crimp die is specifically designed to deliver an optimal factory crimp on your .375 Winchester cartridges, ensuring superior bullet retention and consistent performance during firing.
Utilizing advanced metal forming technology, this die firmly secures the projectile to the case neck more effectively than conventional crimping dies, without causing any deformation or damage to the brass casing or bullet itself.
The die features a specialized crimping collar that compresses the case mouth into the bullets crimp groove, providing a secure and reliable bullet hold essential for maintaining consistent internal ballistics and preventing bullet setback under recoil.
Extensive testing conducted by Lee Precision has demonstrated that employing a Factory Crimp Die results in a more uniform pressure curve throughout the firing cycle, which directly contributes to enhanced shot-to-shot accuracy and improved overall ballistic consistency.
These tests also reveal that even projectiles lacking a dedicated crimp groove benefit from the application of a factory crimp, achieving tighter groupings and improved precision due to the enhanced bullet retention.
The application of a proper crimp increases the initial resistance the bullet encounters before movement, thereby elevating the initial chamber pressure threshold. This elevated crimp pressure ensures a more stable and predictable pressure curve, reducing velocity variation and improving downrange performance.
This die is highly recommended for use in semi-automatic rifles and lever-action firearms, where consistent bullet retention is critical to reliable feeding and cycling.
Please note that the Shellholder is not included with this die and must be sourced separately.
Constructed from durable, hardened steel to withstand repeated use and maintain precise tolerances over time.
Compatible with reloading presses that accept the standard 7/8"-14 thread size, ensuring broad compatibility with most popular reloading equipment.
Supplied in a protective plastic storage case to safeguard the die from damage and contamination when not in use.
