The Lee Taper Crimp Die is just the tool you need to tackle crimp problems caused by poor design. This taper-crimp die is made from hardened steel to ensure a lifetime of durable performance and comes in a variety of sizes to accommodate all of the most popular cartridge calibers. Not only is the Lee Taper Crimp Die ruggedly durable, but it is highly affordable as well. Keep in mind that this taper crimp die does not provide significant advantage when used with Lee dies made after 1986, because the crimp angle of those dies has already been modified to a taper crimp.
