MatchMaster Duo Dies

The MatchMaster Duo die set is an ideal package for competitive shooters and those who value consistency and fine adjustments.

The single die box contains both a full-length sizing die and a micrometer seating die with a bullet-drop window.

This allows you to drop the bullet into the die for perfect alignment. (You can still place the bullet in the case if you prefer.)

RCBS’s Micrometer Seating Die has a clip inside with multiple positions, allowing you to optimize the height of the opening and positioning of the micrometer scale.

From RCBS:

For handloaders demanding uncompromising precision with ironclad dependability, the new MatchMaster™ Duo™ series of reloading dies delivers elite-level consistency in one powerful package.

Duo pairs RCBS’s premium MatchMaster Seating Die—engineered for micrometer–adjustable, repeatable seating depth—with a rugged RCBS Full-Length Sizing Die, trusted by generations of reloaders.

Available in a host of popular new cartridges as well as proven favorites, the Duo series is match-ready out of the box.

- MatchMaster Seating Die + Full-Length Sizing Die
- No bushings required
- Available in Popular Cartridges: 22 ARC to 338 Lapua
- Limited Lifetime Warranty

Previous MatchMaster sets included a bushing die and the micrometer seater. I personally prefer a full-length sizer.

This set is available in a wide variety of cartridges.
