Overview

This die is designed for handloaders working with .38 Special, .357 Magnum, and .357 MAX ammunition who want a consistent crimping step that also sizes the cartridge for reliable chambering. It applies a roll crimp, and the adjusting screw makes it straightforward to set the amount of crimp needed for the load. Because trim length is not critical, it can reduce case-prep time compared with trimming and chamfering each case. It is aimed at producing dependable ammunition where a firm crimp is important, including loads using slow-burning magnum powders.
