LEE 90590 FACT CRIMP DIE 300AAC BLKOUT

Lee Precision 90590 Factory Crimp Die 300 Blackout
This Factory Die incorporates a collet to apply a rifle type crimp to the case, which makes these very difficult to crimp cartridges a delight to reload. Bullets do not need a crimp groove, as the collet is so powerful it will form one.
