Lee Precision 90865 Carbide Factory Crimp Die 45 Colt/454 Casull

The Lee Precision 90865 Carbide Factory Crimp Die delivers consistent bullet retention and case mouth uniformity for both 45 Colt and 454 Casull cartridges. This dual-caliber crimp die eliminates the need for case lubrication while providing precise bullet seating depth control. Advanced reloaders rely on this carbide construction for extended die life and superior performance across thousands of reloading cycles.

What Makes This Different

Unlike standard steel crimp dies that require case lubrication, this carbide version processes brass cases smoothly without additional lubricants. The factory crimp design applies controlled pressure around the entire case mouth rather than just four points like traditional roll crimp dies. This approach reduces case stress while maintaining optimal bullet retention force. The dual-caliber capability handles both 45 Colt and 454 Casull cases with identical threading and shell holder requirements.

Key Features

• Carbide construction eliminates need for case lubrication during crimping process
• Factory crimp design applies uniform pressure around entire case circumference
• Compatible with both 45 Colt (LC) and 454 Casull cartridge cases
• Standard 7/8-14 thread pitch fits most single-stage and progressive presses
• Hardened steel construction with carbide ring for extended service life
• Includes detailed instructions for proper die adjustment and setup
• Works with cast, jacketed, and plated bullets up to maximum case length

This crimp die maintains consistent bullet pull force across different bullet weights and styles, from 200-grain target loads to heavy 300-grain hunting bullets. Competition shooters appreciate the uniform case mouth tension that contributes to consistent velocities and improved accuracy. The carbide ring withstands the higher pressures associated with 454 Casull loads while processing standard 45 Colt cases with equal precision. Field testing demonstrates reliable performance through temperature extremes and extended shooting sessions.
