Lee Precision 90087 Factory Crimp Die 22 TCM Bottleneck Reloading

The Lee Precision 90087 Factory Crimp Die delivers consistent bullet seating and case mouth crimping for 22 TCM ammunition. This bottleneck-specific die eliminates inconsistent crimping that can affect accuracy and feeding reliability in semi-automatic firearms.

What Makes This Different

Unlike standard taper crimp dies, the Factory Crimp Die uses a collet system that crimps into the bullet's cannelure groove. This design maintains consistent overall cartridge length while providing uniform case tension. The die works independently of seating depth variations, ensuring reliable crimping even with mixed brass or slight dimensional differences.

Key Features

• Collet-style crimping system for consistent bullet retention
• Works with cannelured and non-cannelured bullets
• Standard 7/8"-14 threading fits most reloading presses
• Hardened steel construction with precision-machined threads
• Includes detailed instructions and load data references
• Compatible with progressive and single-stage presses
• Reduces bullet setback in semi-automatic magazines

The Factory Crimp Die addresses feeding issues common with bottleneck pistol cartridges like 22 TCM. Proper crimping prevents bullet setback during magazine loading and chambering, maintaining consistent powder charges and safe pressures. Competitive shooters benefit from improved accuracy through uniform bullet release, while the consistent crimp enhances reliability in self-defense applications.
