The RCBS MatchMaster Duo 22 Creedmoor Full Length Die Set (Model R10104) is a premium two-die system designed to produce highly accurate .22 Creedmoor ammunition. Engineered for standard 7/8"-14 thread reloading presses, this set bridges the gap between high-volume brass preparation and match-grade bullet seating precision. It eliminates the need for separate interchangeable neck bushings, simplifying the resizing process while ensuring cases are sized to uniform SAAMI dimensions.

Key Features

• Standard Full-Length Sizing Die: Sizes the entire .22 Creedmoor case to exact SAAMI specifications without requiring individual neck bushings.
• Micrometer-Adjustable Seating Die: Features an oversized, highly legible micrometer adjustment knob where dialling one-thousandth of an inch moves the bullet by exactly that increment for precise seating depth control.
• Bullet Loading Window: Incorporates a cutout window directly in the die body where the user drops the bullet. An internal free-floating, self-centering sleeve aligns the bullet perfectly with the case mouth before seating, eliminating the need to balance bullets on the case mouth by hand.
• Standard Press Compatibility: Features standard 7/8"-14 threading to fit most single-stage and turret reloading presses.

Who is the Rcbs 22 Creedmoor Matchmaster Duo Die Set for?

• 22 Creedmoor precision rifle handloaders — requiring a specialized .22 Creedmoor reloading die set that integrates with standard 7/8"-14 thread presses and interfaces with an RCBS Shell Holder #3 to streamline case preparation without the complexity of sizing bushings.
• Long-range hunters loading match-grade ammunition — seeking to load highly accurate cartridges using a 7/8"-14 thread press and RCBS Shell Holder #3, benefiting from a self-centering alignment sleeve and a micrometer that adjusts seating depth in precise one-thousandth of an inch increments.

Less suitable for: Handloaders who require ultra-specific, incremental control over neck tension in steps of .001 inches, who would be better served by a match-grade bushing die set that utilizes interchangeable sizing bushings.
