Lee Precision 90821 Factory Crimp Die 7mm Remington Magnum

The Lee Precision Factory Crimp Die in 7mm Rem Mag is the finishing touch for any handload, applying a precise factory-style crimp that holds the bullet firmly in the case mouth. Designed as part of Lee's renowned reloading die lineup, this dedicated rifte crimp die uses a collet to squeeze the case mouth uniformly into the bullet's crimping groove for consistent neck tension and improved bullet pull.

A factory crimp die is typically run as the final stage in a reloading press, following the resizing, expanding, and seating operations, and it is especially useful for any rifle cartridge that will see repeated handling, magazine feeding, or use in semi-auto and lever-action platforms where bullet setback is a concern. Because it crimps to a fixed dimension tied to the case trim length, the die is specific to 7mm Rem Mag and is not interchangeable with other cartridges unless they share the same bullet diameter and case trim length.

Model 90821 is machined from steel and built to the standard 7/8x14 threading, allowing it to mount in virtually any standard reloading press on the market. This single die (sold one to a set) provides the consistent crimp that factory-loaded ammunition enjoys.
