Forster Products Accu-Ring Die Lock Ring Features The Forster Accu-Ring Die Lock Ring replaces guesswork with precision by marking reference points in increments of 0.001 inch the distance between a long and short reference mark on the ring. Each reference mark corresponds to an actual movement of 0.000998 inch in the Co-Ax Reloading Press which for practical purposes reads as a true one thousandth of an inch adjustment. This lets reloaders dial in die height with a level of repeatability that a standard lock ring cannot match. On a sizing die that precision translates directly into consistent headspace length from case to case. The same ring also serves a secondary role on seater dies where fine adjustments to bullet seating depth can make a measurable difference in accuracy and chambering consistency. Because the markings are built into the ring itself reloaders do not need separate measuring tools to track small adjustments between sizing or seating sessions. This makes the Accu-Ring especially useful for load development where small repeatable changes need to be tracked and returned to later. For reloaders using a Forster Co-Ax press who want finer control over their dies the Accu-Ring Die Lock Ring is available for sale at GrabAGun.
