Hornady Expander Taper Crimp Super Carry Die Features The Hornady Expander Taper Crimp Super Carry Die works in the final stage of the reloading sequence closing the case mouth flare that the expander die opened to accept the bullet. A milled seater adjustment screw at the top of the die controls bullet seating depth while a separate crimp adjustment screw below it secured with its own lock ring sets how firmly the case mouth closes around the bullet. Backing off the seater screw and the crimp screw lock ring allows the crimp to be dialed in independently of seating depth so handloaders can fine tune the crimp without disturbing a properly set seating depth. This two step adjustment process gives reloaders precise control over the finished taper crimp on every round they produce. Built to Hornady s reloading tolerances at a .3115 diameter for .30 Super Carry this die is machined for repeatable results load after load. A properly applied taper crimp maintains a sharp square case mouth edge rather than rolling it over which is critical for correct headspacing in cartridges that headspace off the case mouth. That sharp edge also improves how reloaded cases feed and chamber in semiautomatic handguns reducing the feeding issues that can come from an improperly crimped case. For reloaders running .30 Super Carry through a semi-auto pistol this die is a straightforward way to produce ammunition that feeds and functions reliably.
