Lee Factory Rifle Crimp Die .223 Rem

The Lee Factory Rifle Crimp Die .223 Rem (Model 90817) is a precision reloading tool designed to produce ammunition that chambers as smoothly as factory-loaded rounds. Built around a carbide sizer, this die simultaneously resizes and crimps .223 Remington cartridges in a single operation—eliminating the need for a separate crimping step and reducing production time during high-volume reloading sessions.

The carbide sizer element ensures that every completed round achieves factory-spec chamber fit, which directly translates to reliable feeding, consistent accuracy, and extended magazine spring life. Adjustment is straightforward: a single set screw controls crimp depth, allowing you to dial in the exact amount of crimp required. The die accommodates both cannelured and non-cannelured bullets, making it versatile for shooters working with various bullet types and sources. Its compact footprint (1.7 x 1.55 x 4.7 inches) integrates easily into any standard reloading press setup.

This die is essential for competitive shooters, defensive ammunition developers, and high-round-count reloaders who demand consistent performance. The .223 Remington remains the standard rifle cartridge for AR-15 platforms and precision rifle training, where ammunition concentricity and crimp consistency directly affect group size and reliability. Whether you're loading match ammunition for the 100-yard line or preparing duty-grade rounds, the Lee Factory Rifle Crimp Die delivers the precision required for repeatable results across large batches.

Lee Precision tools are widely recognized in the reloading community for combining straightforward operation with durable construction. This crimp die represents an economical entry point into single-stage precision reloading without sacrificing functional quality—particularly valuable for operators and shooters who need to manage ammunition costs while maintaining strict quality control.
