Designed for handgun cartridges which headspace on the case mouth where conventional roll crimping is undesirable. Also available for some revolver cartridges, for those who prefer the uniformity of a taper crimp. Profile Crimp Dies These handgun cartridge crimp dies were designed for those who want the best possible crimp. Profile crimp dies provide a tighter, more uniform roll type crimp, and requires the bullet to be seated to the correct depth in a previous operation. These dies are not for cartridges that headspace on the case mouth.
