Factory Crimp Die Caliber 7.5x55 Swiss LEE for Reloading and Precision Shooting
Lee Factory Crimp Die for 7.5x55 Swiss Caliber.
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.
Utilizing advanced metallurgy and machining techniques, this die firmly secures the projectile to the case neck more effectively than conventional crimping tools, without causing deformation or damage to the brass case or its neck.
The die features a specialized crimping collar that compresses the case mouth precisely into the bullets crimp groove, delivering a reliable and repeatable bullet hold essential for semi-metallic and metallic cartridge reloading.
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 accuracy on the range.
Empirical data confirms that even projectiles lacking a dedicated crimp groove benefit from the use of this die, achieving tighter groupings and superior ballistic stability under various shooting conditions.
The application of a firm crimp increases the initial resistance to bullet movement, requiring higher ignition pressure before the projectile begins to travel down the barrel. This elevated initial pressure stabilizes internal ballistics, reducing velocity variation and promoting consistent muzzle velocities.
This controlled pressure curve is critical for maintaining precision, especially in semi-automatic and lever-action firearms, where reliable bullet retention prevents feeding issues and enhances overall firearm reliability.
Recommended primarily for use with semi-automatic rifles and lever-action platforms chambered in 7.5x55 Swiss, this die is an essential tool for reloaders seeking to maximize cartridge performance and shooting accuracy.
Please note: Shellholder is not included and must be acquired separately.
Constructed from high-grade hardened steel to withstand repeated use and maintain dimensional integrity over time.
Compatible with reloading presses that accept the standard 7/8"-14 thread size.
Supplied in a durable plastic storage case for protection and easy organization of your reloading components.
