Lee Undersize Sizing Die Only Carbide .38 Spl/.357 Magnum. Used in conjunction with the Lee Large Series Carbide Sizing Die (No Shell Holder) the Carbide Undersize Die achieves the optimum sizing rate with every pull of the trigger. Carbide is the preferred material for bore sizing dies because its wear resistance prevents scratches and nicks. Carbides also retain their shape giving you a lifetime of use. These dies have extra ground relief to allow for larger case bulge.
