Lee Precision 90853 Factory Crimp Die 38-55 Winchester Reloading

The Lee Precision 90853 Factory Crimp Die delivers consistent bullet seating and case mouth crimping for 38-55 Winchester cartridges. This specialized reloading die applies the exact crimp profile used in factory ammunition, ensuring reliable feeding and optimal accuracy in lever-action rifles.

What Makes This Different

Unlike standard roll crimp dies that can buckle thin brass walls, the Factory Crimp Die uses a collet system that crimps into the bullet's cannelure groove. This design maintains case wall integrity while providing uniform bullet retention across different brass manufacturers. The die works with both jacketed and cast bullets, accommodating the diverse projectile types commonly used in 38-55 Winchester loads.

Key Features

• Collet-style crimping system prevents case wall damage and buckling
• 7/8-14 standard threading fits all major reloading presses
• Hardened steel construction with precision-machined tolerances
• Works with jacketed, plated, and cast lead bullets
• Includes detailed instructions and load data references

This die proves essential for hunters loading heavy bullets in 38-55 Winchester cartridges, where proper crimp prevents bullet setback during magazine feeding in Marlin 336 and Winchester 94 rifles. The consistent crimp pressure improves ignition uniformity, contributing to better accuracy at extended ranges. Competitive shooters appreciate the die's ability to maintain precise overall cartridge length while ensuring reliable extraction.
