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. Forster Full Length Sizing Dies are each equipped with their E-Z Out Expander button which helps keep case necks concentric during the neck expanding operation. It's positioned higher in the neck area than most other dies. This provides support and holds the axis of the neck and case in alignment while the case is withdrawn from the die.
