Overview

Built for handloaders working with .44 Special, .44 Magnum, and .44 Russian cartridges, this carbide factory crimp die combines crimping and sizing in one step to help produce rounds that chamber smoothly. It applies a roll crimp, and the adjusting screw lets you set the crimp level with minimal fuss. Because trim length is not critical, it can reduce case-prep time compared with trimming and chamfering. It is a practical choice when a firm, consistent crimp is part of your loading routine.

  • The die sizes the cartridge while crimping, so it adds an extra operation to the loading process even though trim length is less critical.
