The RCBS MatchMaster Competition Neck Bushing Die Set brings together premium features from both the Gold Medal and Competition series. The neck sizing die employs RCBS’s precision-machined neck bushings to establish optimal neck tension on each round without altering the body dimensions of fired cases. A titanium nitride coated expander delivers smooth case extraction and minimizes brass buildup on the expander, both of which reduce neck stretch.
The MatchMaster Competition Seating Die completes the set, featuring a bullet seating window with bullet retaining system—position the bullet in the window and raise the case into the die to seat it. Both dies are manufactured from case-hardened steel with inside surfaces precision-drilled and reamed to exacting standards, then hand polished to ensure smooth and consistent operation. The bullet seating window includes a bullet retention system that improves accuracy during seating and prevents bullet deformation.
MatchMaster sizing dies accept interchangeable neck bushings (sold separately), a system relied upon by benchrest and long-range precision shooters. The self-centering, changeable neck bushing allows precise adjustment of bullet tension, reducing brass work and extending case life. This die set includes a limited lifetime warranty, guaranteeing quality and reliability for the long term.
