Overview

This taper crimp die is intended for handloaders working with .45 ACP and related cartridges who need a more controlled crimping step at the bench. It is described as addressing crimp problems caused by poor die design, making it a practical option when setup issues are affecting consistency. The product also notes that it offers little or no advantage with 1986 or newer Lee dies, since those already use a modified taper crimp angle. For reloaders evaluating a dedicated crimp die, its value depends on the dies already in use and the specific crimping problem being addressed.

Considerations & Trade-offs

  • Intended for specific .45-caliber cartridges listed in the product data, so it is not a universal crimp solution.
