Lee Precision 90926 Collet Crimp Die 460 S&W Magnum Reloading

The Lee Precision 90926 Collet Crimp Die delivers consistent bullet retention for 460 S&W Magnum cartridges without case deformation. This specialized crimping die maintains proper bullet seating depth while providing the secure crimp needed for magnum revolver performance.

What Makes This Different

Unlike standard roll crimp dies that can buckle thin-walled magnum cases, this collet design applies uniform radial pressure around the entire case mouth. The segmented collet contracts evenly when the die is operated, creating a factory-quality crimp that won't distort case walls or affect overall cartridge length. This precision approach extends case life significantly compared to conventional crimping methods.

Key Features

• Collet-style crimping prevents case mouth distortion and buckling
• Maintains consistent overall cartridge length for reliable feeding
• Compatible with all standard 7/8-14 thread reloading presses
• Hardened steel construction withstands high-pressure magnum loads
• Includes lock ring for repeatable die positioning
• Works with jacketed, cast, and plated bullets up to .452 diameter
• No case length trimming required for proper crimp formation

This die excels in high-volume reloading scenarios where consistency matters most. Competition shooters appreciate the uniform bullet pull resistance that contributes to shot-to-shot velocity consistency. The gentle crimping action preserves case integrity through multiple reloading cycles, making it economical for shooters who reload frequently. Weather conditions don't affect the mechanical crimping process, ensuring reliable ammunition production year-round.
