Lee Factory Crimp Die for .303 British caliber ammunition.
This precision-engineered crimp die is specifically designed to provide an optimal factory crimp on your reloads, ensuring consistent and reliable cartridge performance.
Unlike standard dies, this crimp die firmly secures the bullet to the case neck without causing any deformation or damage to the brass or bullet itself, preserving the integrity of each component.
The die features a specialized collet mechanism that compresses the case mouth precisely into the bullets crimp groove, delivering a secure and repeatable bullet hold essential for high-velocity and semi-metallic cartridge applications.
Extensive testing conducted by Lee has demonstrated that utilizing a Factory Crimp Die results in a more uniform pressure curve during firing, which directly translates into enhanced ballistic consistency and improved shot-to-shot accuracy.
These tests also confirm that even projectiles lacking a factory crimp groove benefit significantly from the dies ability to maintain bullet retention, thereby increasing precision and reducing velocity variation.
The enhanced crimping process elevates the initial resistance pressure required to overcome bullet movement, ensuring that the projectile remains firmly seated until the optimal moment of ignition.
This higher initial crimp pressure contributes to a smoother internal ballistics profile, minimizing pressure spikes and velocity spreads, which are critical factors in precision shooting and reliable semi-automatic cycling.
Recommended for use in semi-automatic rifles and lever-action firearms chambered in .303 British, this die is an indispensable tool for reloaders seeking to maximize performance and safety in their ammunition.
Please note that the Shellholder is not included and must be purchased separately.
Constructed from durable, hardened steel to withstand repeated use and maintain dimensional accuracy over time.
Compatible with reloading presses that accept the standard 7/8"-14 thread size.
Supplied in a protective plastic case for safe storage and transport.
