Frequently Asked Questions

Why use a taper crimp on auto-pistol cartridges? A taper crimp removes the case mouth flare from bullet seating without rolling the mouth inward, which helps semi-auto pistols feed and headspace correctly on the case mouth.

Does this die replace my seating die? No, it’s a dedicated crimp die meant to be run as an additional station alongside your sizing and seating dies.
