Lee Precision Multi-Caliber Carbide Sizer Reloading Die

Lee Precision’s Carbide Factory Die simultaneously sizes and crimps cartridges to deliver factory-grade reliability and consistent chambering. The die uses a roll style crimp, with an adjusting screw that allows quick, precise control over crimp intensity. Because trim length is not critical with this die, you save time by eliminating the separate trimming and chamfering step. A firm crimp is essential for dependable and accurate ammunition, as it eliminates the problems of poor ignition of slow burning magnum powders.
