Lee Precision Factory Crimp Die 243 Winchester

The Lee Precision Factory Crimp Die is a single-purpose reloading die for the 243 Winchester cartridge, designed to crimp completed reloads to the same standard as factory ammunition. Built around a precision collet, this die applies a uniform rifle-type crimp to the case mouth, locking the bullet in place for reliable feeding and consistent performance.

Crafted from steel, the Factory Crimp Die serves as the final step in a reloading sequence. It is intended for use after the resizing and bullet-seating operations to apply a precise, taper-free crimp on the cartridge. The collet design squeezes only the very end of the case into the crimping groove of the bullet, improving bullet pull without distorting the case body or altering overall length.

This die features standard 7/8"-14 threads to fit any reloading press that accepts the common reloading thread pattern. The Factory Crimp Die accommodates a wide range of bullet profiles, including bonded and jacketed designs. As a single-die accessory rather than a full die set, it is the ideal add-on to an existing Lee or other-brand 243 Winchester reloading setup.
