RCBS Matchmaster Features The RCBS Matchmaster Seating Die is machined from case hardened steel with internal surfaces precision-drilled reamed and hand polished to exacting standards. Finished with a deep blued coating reminiscent of fine firearms the die is built for reloaders who demand both performance and craftsmanship. A free-floating self-centering bullet seating stem guides the bullet during the seating operation for astoundingly concentric results. This level of precision helps ensure every loaded round for the .338 ARC meets match-grade consistency standards. The large oversized micrometer adjustment knob features oversized letters and hash marks making it easy to dial in exact seating depth adjustments of one thousandth of an inch at a time. An exclusive loading window allows reloaders to simply drop the bullet in and run the press removing the risk of balancing a bullet on the case mouth or placing fingers in danger. Built on a standard 7/8 inch 14 thread pattern the die fits standard reloading presses without modification. Backed by a limited lifetime warranty and made in the USA the RCBS Matchmaster Seating Die is available for sale at GrabAGun.
