Forster Reloading Dies are of excellent quality and provide the reloader with the ability to produce concentric rounds time and time again. Each die is manufactured from the finest quality steel carefully machined to very tight tolerances. Dies are hand polished both before and after the heat-treating process to guarantee an extra fine finish. All Forster reloading dies feature their Forster Cross Bolt Die Locking Ring that tightens the two ends of the split ring instead of tightening a screw directly into the threads of the die. Neck Sizing will enable the reloader to retain the fire formed dimensions of their cases rather than resizing the entire case. Neck sizing can prolong case life and eliminate some problems associated with excessive headspace. Like the Forster Full Length Sizing Dies, neck dies also included and E-Z Out Expander button assembly and Cross Bolt Lock Ring.
