Lee Factory Rifle Crimp Die .348 Win

The Lee Factory Rifle Crimp Die .348 Win (Part No. 90857) is a precision reloading tool designed to simultaneously size and crimp rifle cartridges, ensuring every loaded round chambers with factory-spec consistency. The integrated carbide sizer post-sizes your .348 Winchester ammunition while applying a controlled crimp in a single operation, eliminating the need for a separate crimping step and reducing handling time at the bench.

This .348 Win crimp die accommodates a wide range of bullet designs, including jacketed rounds without cannelures—a significant advantage over standard tools that may fail on non-cannelured bullets. The adjustable screw allows precise control over crimp depth, preventing over-crimping that can compress powder charges or under-crimping that leaves loose bullets vulnerable to setback. Lee Precision's carbide construction delivers durability through thousands of reloading cycles while maintaining dimensional tolerances critical for consistent chamber fit and reliable feeding.

Shooters reloading for .348 Winchester—a powerful lever-action cartridge favored in backcountry hunting and medium-to-large game applications—benefit from the factory-grade results this die produces. Proper crimping prevents bullet migration during recoil, maintains consistent seating depth shot-to-shot, and reduces the likelihood of dangerous pressure spikes caused by loose rounds. This die integrates into standard Lee progressive and single-stage presses, making it an essential addition for handloaders seeking repeatable, field-proven ammunition performance.
