Lee Precision 90841 Factory Crimp Die 7mm Express / 280 Rem

The Lee Precision 90841 Factory Crimp Die is a single-die factory crimp solution for reloaders working with the 7mm Express and 280 Remington. Built around Lee's signature collet-style crimping system, this steel die applies a uniform rifle-type crimp while simultaneously post-sizing the case to guarantee reliable chambering.

Designed as the finishing step in a reloading press, the Factory Crimp Die takes the guesswork out of crimping bottleneck rifle cases. The collet squeezes the case mouth evenly around the bullet, locking the projectile in place and preventing it from shifting during magazine feed or recoil. The integrated sizer brings the cartridge back to factory dimensions, eliminating the slight bulging that can occur during bullet seating and ensuring every round drops freely into the chamber.

Sold as a single die, the 90841 serves as the dedicated crimping step in a reloading workflow for the 7mm Express / 280 Rem, complementing a separate resizing and seating die set. It is an essential finishing tool for any handloader chasing consistent feeding and reliable performance from these classic medium-bore cartridges.
