The Lee Precision 90421 Factory Crimp Die delivers consistent bullet seating and case mouth crimping for .30 M1 Carbine ammunition. This specialized reloading die addresses the unique requirements of the M1 Carbine cartridge, ensuring proper headspace and reliable feeding in both military surplus and commercial firearms.
What Makes This Different
The Factory Crimp Die system applies a post-sizing crimp that maintains consistent overall cartridge length while providing the exact bullet grip needed for semi-automatic function. Unlike traditional roll crimp dies that can vary crimp intensity based on case length variations, this die delivers uniform results regardless of minor brass inconsistencies. The collet-style crimping mechanism works independently of case length, producing ammunition that meets original military specifications.Key Features
