Overview

Designed for reloaders working with 45 Colt and 454 Casull, this taper crimp die is intended to address crimp issues that can arise from poor die design. It is a practical option for those trying to correct a specific setup problem rather than add a new feature to an already well-matched die set. Lee notes that it offers little or no advantage with 1986 or newer Lee dies, since those already use a modified taper crimp angle. For shooters evaluating a replacement or corrective die, the key value is in resolving compatibility and crimping concerns within an existing loading setup.
