Factory Crimp Die Caliber 45-70 LEE for Reloading and Precision Shooting
Lee Factory Crimp Die for .45/70 Government Caliber
This precision-engineered crimp die is specifically designed to provide an optimal and consistent crimp on your .45/70 Government cartridges, ensuring superior bullet retention and enhanced ballistic performance.
Utilizing advanced mechanical tolerances, this die firmly secures the projectile to the cartridge case more effectively than conventional crimping tools, without causing deformation or damage to the brass casing or bullet jacket.
The die features an integrated crimping collet that compresses the case mouth into the bullets crimp groove, delivering a robust and reliable bullet hold that withstands the rigors of semi-automatic and lever-action firearm cycling.
Extensive testing conducted by Lee Precision has demonstrated that employing the Factory Crimp Die results in a more uniform pressure curve during ignition, which directly translates to improved shot-to-shot consistency and enhanced overall accuracy.
Remarkably, even projectiles lacking a dedicated crimp groove benefit from this dies ability to stabilize bullet seating, yielding tighter groupings and reduced velocity variance.
The enhanced crimping process elevates the initial bullet release pressure, ensuring the projectile remains firmly seated until chamber pressure reaches an optimal threshold, thereby minimizing bullet set-back and improving internal ballistics.
This higher initial release pressure contributes to a smoother and more predictable pressure curve, reducing velocity fluctuations and promoting consistent muzzle velocities.
Recommended primarily for use with semi-automatic and lever-action rifles chambered in .45/70 Government, this die is an essential tool for reloaders seeking to maximize reliability and precision in metallic and semi-metallic cartridge reloading.
Please note: Shellholder is not included and must be sourced separately.
Constructed from high-grade hardened steel for durability and long service life under rigorous reloading conditions.
Compatible with reloading presses that accept the standard 7/8"-14 thread size.
Supplied in a protective plastic storage case to safeguard the die from environmental contaminants and mechanical damage.
