The Redding .223 Remington National Match 3-Die Set (MPN 39111) is an advanced reloading system engineered for precision handloading. Designed around the .223 Remington cartridge, this 3-die set delivers match-grade bullet alignment and consistent case dimensions required for reliable feeding and tight groupings in competition rifles. The set mounts directly into standard single-stage or progressive reloading presses via its 7/8"-14 thread pitch and is operated manually without external power requirements.

Key Features

• Full-Length Sizing Die with Carbide Expander: Resizes the full case body and features a free-floating carbide size button that reduces neck stretch on the upstroke and eliminates the requirement for inside-neck lubrication.
• Competition Bullet Seating Die: Utilises a tight-tolerance sliding alignment sleeve to fully support the case and bullet before seating begins, coupled with a micrometer head calibrated in 0.001-inch increments for repeatable seating depth adjustments.
• Dedicated Taper Crimp Die: Applies a precise taper crimp in a separate step to secure the bullet firmly against recoil and semi-automatic cycling without buckling case shoulders.

Who is the Redding 223 Rem National Match Die Set for?

• Competitive service rifle shooters — Benefit from the 0.001" micrometer-adjustable seating stem on this 223 Rem reloading die set, allowing precise, repeatable bullet seating depths tailored to strict magazine-length requirements.
• Precision rifle shooters running semi-automatic or gas-operated rifles — Require the full-length resizing die and dedicated taper crimp die in this 223 Rem reloading die set to guarantee reliable chambering across standard 7/8"-14 threaded presses while preventing bullet setback during aggressive feeding cycles.
• Match competitors — Need the internal sliding alignment sleeve found in this 223 Rem reloading die set to guide both the case and .224" bullet into concentric alignment before seating, keeping bullet runout to a minimum.

Less suitable for: Handloaders seeking to only neck-size fire-formed brass for bolt-action rifles, where dedicated neck-sizing dies are preferred over full-length resizing, or shooters wanting custom neck tension via interchangeable diameter bushings, who require a Type-S match bushing die set.
