RCBS Offers New MatchMaster Sizing and Seating Dies

RCBS has introduced a new series of MatchMaster Competition Dies. These are available in Full-Length Sizing, Neck Sizing, and Seating configurations. These new MatchMaster dies are notable for four features:

1. The Competition Seating Die has a “view-port” for the bullet.
2. The Competition Seating Die features a free-floating, self-centering bullet-seating stem.
3. Expanders are titanium-nitride coated for reduced friction. Both the Neck-Sizing and FL-Sizing dies come with TiN expanders for smoother case extraction and reduced brass build-up on the expander.
4. RCBS is offering its own precision-machined Neck Bushings.

No More Mashed Fingers When Seating Bullets
RCBS notes: “Reloaders will love that they can end smashed fingers and misaligned bullets with the specially-designed bullet window [on the Seating Die]. And users can fine-tune any load … with the micrometer-adjustable, free-floating, self-centering bullet seating stem.”

RCBS Product Manager Will Hemeyer explained that the new Competition Seater is a game-changer. “What sets the MatchMaster Seating Die apart from the competition is a bullet-seating window with bullet-retaining system. Simply place the bullet in the window and raise the case into the die to seat the bullet. Couple this with a micrometer-adjustable, free-floating, self-centering bullet-seating stem and the MatchMaster Seating Die is easily the most accurate bullet seating die on the market.”

Gavin Gear of UltimateReloader.com has tested the new RCBS MatchMaster Dies in 6mm Creedmoor. He was very impressed with the new Competition Seater and he liked the TiN-coated expanders on the sizing dies. Watch Gavin’s video:

Why Use Expander with Bushing Dies?
Some viewers of Gavin’s video asked if an expander is superfluous when using neck-bushing dies. The answer is “it depends”. The bushings reduce neck diameter from the OUTSIDE. The expander should make the INSIDE of the neck perfectly round. Some hand-loaders prefer to take the necks down a couple thousandths below final loading diameter, then finish the job with an expander. That ensures the INSIDE of the case neck is perfectly concentric. This can be particularly useful for brass that has somewhat inconsistent neck-wall thickness. Bottom line, you can run these dies without expanders if you want, but that option is available. The expander is also removable so the assembly can be used for de-capping only.

MactchMaster Neck-Sizing Only Die
The MatchMaster Neck Sizing Die Set also uses RCBS neck bushings to control neck tension while not changing the body dimensions of fired cases. Frankly we strongly recommend that you full-length size your rifle rounds, but we acknowledge that some hand-loaders prefer to neck size for some applications. The MatchMaster Neck Sizing Dies do include a titanium-nitride coated expander, just like the FL-sizing MatchMaster dies.
