RCBS Matchmaster Features The RCBS Matchmaster Seating Die for .300 Norma Mag sets itself apart with a bullet loading window paired with a bullet retaining system letting the reloader drop a bullet into place and raise the case straight into the die to seat it. This eliminates the fumbling and misalignment that come with traditional seating methods speeding up the reloading process while improving consistency. A free floating self centering seating stem further ensures that each bullet seats straight along the case axis reducing runout across a batch of ammunition. That kind of repeatability is exactly what long range shooters need from their handloads. Fine seating depth adjustments are handled through a micrometer system giving the reloader precise repeatable control over cartridge overall length for a given rifle s chamber and throat. This level of adjustability matters most when chasing the last few thousandths of accuracy out of a magnum cartridge like .300 Norma Mag. RCBS built the Matchmaster line by drawing on the strengths of its established Gold Medal and Competition dies resulting in a seating die trusted by serious precision shooters. For anyone loading .300 Norma Mag for long range competition or hunting this die delivers both speed and precision at the bench.
