Overview

Designed for reloaders working with .40 S&W and 10mm Auto, this taper crimp die is intended to address crimp issues associated with poor die design. It is a practical add-on for those who need a dedicated crimping solution in their loading setup. The product notes that it offers little or no advantage when used with 1986 or newer Lee dies, since those already use a modified taper crimp angle. For that reason, it is best suited to users evaluating older die setups or specific crimping problems rather than seeking a general upgrade.

Considerations & Trade-offs

  • Designed for .40 Smith & Wesson and 10mm Auto only, so it is not a general-purpose crimp die for other cartridges.
  • The product notes that it offers little or no advantage when used with 1986 or newer Lee dies, which limits its value if you already have those dies.
  • Its purpose is specific: addressing crimp problems caused by poor die design, so it is most relevant as a corrective tool rather than a universal upgrade.
