Lee 90822 Factory Crimp Die 30-30Win 

Lee Factory Crimp Die incorporates a collet to apply a rifle type crimp to the case. Makes even the most 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. A firm crimp improves accuracy because pressure must build to a higher level before the bullet begins to move. This higher start pressure insures a more uniform pressure curve and less velocity variation.

NOTE: This die is not carbide.
