The RCBS 28004 MatchMaster Duo Set for 6mm ARC pairs two essential tools for reloaders who want precision without compromise. This set combines RCBS's MatchMaster seating die—engineered with micrometer adjustment for repeatable, consistent seating depth—with a full-length sizing die built on generations of proven design. If you're loading for the 6mm ARC and want match-grade accuracy straight out of the box, this two-die combo delivers the precision and reliability serious handloaders depend on.
The MatchMaster seating die is the star here: its micrometer adjustment lets you dial in exact seating depth and lock it in, so every round you load sits at the same depth. That consistency matters when you're chasing tight groups at distance. The full-length sizing die handles case preparation with the durability you'd expect from RCBS—it's the same proven design that's been trusted in reloading rooms for decades. No bushings required, which means less fiddling and fewer parts to manage.
The 6mm ARC is a modern intermediate cartridge built for precision and efficiency in short-action systems, and it rewards handloading that pays attention to detail. This die set is purpose-built for that cartridge and engineered to help you achieve the consistency that makes a real difference on target. Made in the USA and backed by RCBS's Limited Lifetime Warranty.
