Lee Precision 90840 Factory Crimp Die 7mm-08 Remington Reloading

The Lee Precision 90840 Factory Crimp Die delivers consistent bullet seating and case mouth crimping for 7mm-08 Remington cartridges. This precision reloading tool ensures uniform cartridge overall length and proper bullet retention across production runs.

What Makes This Different

Unlike standard taper crimp dies that only compress the case mouth, the Lee Factory Crimp Die applies both a taper crimp and a collet-style crimp simultaneously. The dual-action design accommodates slight variations in case length while maintaining consistent crimp pressure. This approach reduces bullet setback during feeding and produces more uniform chamber pressures than conventional single-stage crimping methods.

Key Features

• Dual taper and collet crimp system for superior bullet retention
• Accommodates case length variations up to 0.010 inches
• Hardened steel construction with precision-ground surfaces
• Standard 7/8-14 threading fits most single-stage and turret presses
• Factory-set crimp depth eliminates guesswork and setup time
• Works with all bullet weights and styles in 7mm-08 Remington
• Includes detailed instructions and load data references

Bench testing shows the Factory Crimp Die produces cartridges with less than 0.002-inch variation in overall length when properly adjusted. The consistent crimp pressure translates to improved accuracy potential and reduced velocity spreads in both hunting and target applications. Semi-automatic rifle shooters benefit from enhanced feeding reliability, while bolt-action users see improved consistency shot-to-shot.
