The RCBS Matchmaster Bushing Die Set for .223 Remington (brand part no. 11110) is built for handloaders who measure success in thousandths of an inch, giving .223 Remington shooters a neck-size sizing setup with true match-grade tolerances. Every die in the set is machined from case-hardened steel, then precision-drilled, reamed, and hand polished so the internal bore holds tight tolerances load after load. Instead of a fixed neck expander, the sizing die accepts an interchangeable neck bushing (sold separately) so the reloader can dial in exact neck tension for a specific rifle and bullet combination. As a dedicated neck-size set, it resizes only the case neck rather than the full case body, the preferred approach for brass fired and reloaded in the same rifle chamber.

Key Specifications

• .223 Remington is the chambering this Matchmaster neck-size bushing die set is machined to fit
• Case-Hardened Steel construction runs through every die in the set for long-term wear resistance at the press
• Interchangeable Neck Bushing sizing (bushing sold separately) lets the reloader set exact neck tension instead of relying on a fixed expander
• Self-Centering bushing design keeps the neck bushing centered on the case for concentric, repeatable resizing
• Deep Blued finish on the seater die matches the fit and finish of a fine firearm rather than a shop tool
• Oversized Micrometer adjustment knob on the seating die is graduated in thousandths of an inch with bold, easy-to-read hash marks
• Loading Window on the seater die lets the reloader drop a bullet straight in and run the press instead of hand-balancing it on the case mouth
• Internal Alignment Sleeve captures the bullet and case together during seating for consistently concentric finished rounds
• 7/8-Inch-14 thread pattern on every die means it fits any standard single-stage or turret press

Frequently Asked Questions

Does this set include the neck bushing? No. Matchmaster sizing dies use an interchangeable bushing system, and the bushing itself is sold separately so you can match it to your exact case neck diameter.

Will this die set fit my press? Yes. Every die in the set uses the standard 7/8-inch-14 thread pattern found on virtually all single-stage and turret presses.

Why choose a neck-size-only die instead of full-length sizing? Neck sizing works the case neck only, leaving the body dimensions from your own chamber intact, which handloaders who fire and reload in the same rifle typically prefer for extended brass life and tighter concentricity.
