Description

The Lee Precision 90813 Collet Crimp Die delivers precise bullet seating and consistent case mouth crimping for .357 Magnum cartridges. This specialized reloading die eliminates over-crimping issues while maintaining proper bullet tension for reliable feeding and accuracy.

What Makes This Different

Unlike standard roll crimp dies that can buckle case walls, this collet design applies uniform radial pressure around the entire case mouth. The steel collet fingers compress evenly to create consistent crimp depth without distorting the brass. This controlled crimping process extends case life by 30-40% compared to conventional roll crimp methods while improving overall cartridge concentricity.

Key Features

Steel collet fingers provide 360-degree uniform crimping pressure
Compatible with all standard 7/8-14 thread reloading presses
Eliminates case mouth flare and buckled brass issues
Hardened steel construction for consistent performance over thousands of rounds
Adjustable crimp depth via lock ring positioning
Works with jacketed, lead, and plated bullets from 125-180 grains
Includes detailed setup instructions and crimp gauge reference

This die excels in high-volume reloading scenarios where consistency matters most. Competition shooters benefit from the uniform bullet seating depth that improves accuracy potential, while hunters appreciate the reliable feeding in lever-action rifles. The controlled crimp prevents bullet setback during magazine cycling in revolvers and maintains proper case tension for consistent powder burn rates.
