Lee Precision 90931 Collet Crimp Die 500 S&W Mag

500 S&W Collet Style Crimp Die incorporates a collet to apply a rifle type crimp to the case. 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. NOTE: This die is not carbide.
