LEE Factory Crimp Die Caliber 7mm Express for Reloading and Precision Shooting

90841

Lee Factory Crimp Die for 7mm Express Caliber.

 

This precision-engineered crimp die is specifically designed to provide an optimal and consistent crimp on your metallic and semi-metallic cartridges, ensuring superior bullet retention and enhanced ballistic performance.

 

Utilizing advanced engineering principles, 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 the bullet itself.

 

Equipped with a specialized crimping collar, this die compresses the case mouth precisely into the bullet’s cannelure, delivering a secure and reliable hold that withstands the rigors of semi-automatic and lever-action firearms.

 

Extensive testing conducted by Lee has demonstrated that employing a Factory Crimp Die results in a more uniform chamber pressure curve, which directly translates into improved shot-to-shot consistency and enhanced projectile accuracy.

 

Notably, these tests reveal that even bullets lacking a factory cannelure benefit from the use of this crimp die, achieving tighter groupings and superior ballistic stability.

 

The application of a proper crimp increases the initial resistance against bullet movement, requiring higher ignition pressure 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 promoting consistent muzzle velocities critical for precision shooting and competitive reloaders.

 

Recommended primarily for use in semi-automatic rifles and lever-action firearms where reliable bullet retention is paramount to prevent feeding issues and maintain consistent chamber pressures.

 

Please note: Shellholder is not included with this die.

 

Constructed from high-grade steel for durability and long service life under repeated reloading cycles.

 

Compatible with reloading presses that accept the standard 7/8"-14 thread size.

 

Supplied in a protective plastic case for safe storage and transport.
