RCBS 10610 MatchMaster Neck Sizing Bushing Die Set for 22-250 Remington

The RCBS MatchMaster Neck Sizing Bushing Die Set for 22-250 Remington is built for handloaders who want precision neck control and extended brass life. This is a purpose-built set for reloaders focused on accuracy—benchrest shooters and long-range hunters who understand that case-to-case consistency matters. The two-die set includes a neck sizing die and a bullet seating die, both made from case-hardened steel with precision-drilled, reamed, and hand-polished internal surfaces. If you're stepping up from full-length sizing or working with premium brass you want to preserve, this system gives you that intermediate control.

The heart of the MatchMaster neck sizing approach is the changeable-diameter neck bushing, which lets you dial in exactly how much tension the die applies to your fired case necks. This isn't set-it-and-forget-it; it's adjustable precision. The titanium carbo-nitride expander reduces brass buildup during extraction and keeps case handling smooth. Fewer case-working cycles mean your brass lasts longer—a real advantage when you're processing quality ammunition components repeatedly.

The seating die is where MatchMaster's reputation for fit and finish shows. An oversized micrometer knob with clearly marked graduations lets you dial bullet seating depth to the tenth of a thousandth—and that's exactly what you'll get. The loading window and internal bullet-retention system eliminate the old fumble of balancing a bullet on the case mouth; the system catches and guides the bullet into perfect alignment for concentrically seated rounds. All MatchMaster dies use standard 7/8"-14 threading and are made in the USA.

Note: This set requires separate neck bushings sized to your 22-250 Remington brass—they're not included and must be purchased based on your specific case and desired neck tension.

Frequently Asked Questions

What neck bushings do I need for this die set?

The MatchMaster neck sizing die uses interchangeable, changeable-diameter neck bushings that you select and purchase separately. Your choice depends on your brass type and the amount of neck tension you want. This is by design—it lets you fine-tune fit without buying multiple dies.

Can I use this set with standard reloading presses?

Yes. The MatchMaster dies have standard 7/8"-14 threads, so they'll fit any reloading press with standard die threads. No special equipment is required.

What's included in the box?

The set includes the neck sizing die with titanium carbo-nitride expander and the bullet seating die with micrometer and loading window. Neck bushings are sold separately and must be purchased to match your specific brass and desired tension.

How does the seating die improve bullet seating accuracy?

The loading window and internal bullet-retention system catch and hold your bullet in alignment with the case before seating begins, then guide it concentrically into the case. This eliminates manual bullet positioning and delivers repeatable, concentric results.
