RCBS 7.7X58 Arisaka Full Length Dies Set #14401

This Set of 2 Dies is designed for reloading Bottle Neck Cases and is composed of a full-length sizing die with an expansion-depriming unit and a seating die with bullet seating. The full-length sizing die brings the case to the SAAMI minimum cartridge dimensions. It resizes the outside of the case, expands the neck to accept the bullet. The die has vent holes to prevent case damage caused by trapped air and excessive lubricant. The headspace is maintained to minimum tolerances to avoid altering the case body length during sizing.
