Lee Precision 90843 Factory Crimp Die 30-40 Krag Reloading

The Lee Precision 90843 Factory Crimp Die delivers consistent bullet seating and case mouth crimping for 30-40 Krag cartridges. This specialized reloading die ensures proper neck tension and bullet retention while maintaining the original factory crimp profile that chambers reliably in vintage military rifles.

What Makes This Different

Unlike standard taper crimp dies, the Factory Crimp Die applies the exact crimp profile found on original military ammunition. The die features a collet system that crimps into the cannelure groove without affecting overall cartridge length. This approach prevents bullet setback during feeding while maintaining the precise headspace requirements of 30-40 Krag chambers.

Key Features

• Collet-style crimping system maintains factory ammunition specifications
• Hardened steel construction with precision-ground internal surfaces
• Standard 7/8-14 threading fits all major reloading presses
• Includes detailed setup instructions and load data references
• Post-sizing capability corrects minor case dimension variations
• Compatible with both cast and jacketed bullets in 30-40 Krag
• Knurled lock ring ensures consistent die positioning

This die addresses the unique requirements of 30-40 Krag reloading where proper crimp tension prevents bullet movement in long military actions. The collet design grips the case mouth evenly, eliminating the case distortion common with traditional roll crimp dies. Hunters and collectors loading for Krag-Jørgensen rifles benefit from ammunition that feeds smoothly through the side-loading magazine system while delivering consistent accuracy.
