Lee Precision Factory Crimp Die 300 Blackout

The Lee Precision Factory Crimp Die for .300 AAC Blackout is a purpose-built reloading die that applies a firm, factory-style crimp to bottleneck rifle cases without distorting the case mouth and without dependence on case length.

Rather than rolling or tapering the mouth of the case, the Lee Factory Crimp Die redesigns the case mouth around the bullet, gripping the projectile more firmly than any other reloading tool. The result is improved bullet pull, more consistent ignition, and noticeably better downrange accuracy - especially valuable for the .300 Blackout, which is commonly loaded for both supersonic and subsonic applications.

Machined from steel and cut with the standard 7/8-14 thread, this die installs on virtually any standard single-stage or turret reloading press. This listing is for the crimp die only; a shell holder is not included and must be purchased separately.
