The Redding 39148 National Match Die Set is a dedicated 3-die system engineered for precision reloading of .30-06 Springfield ammunition. Built to deliver match-grade concentricity and reliable semi-automatic cycling, this set includes a full-length sizing die equipped with a free-floating carbide expander button, a Competition Bullet Seating Die featuring an adjustable micrometer, and a dedicated taper crimp die. The carbide size button reduces inside-neck friction and case stretch during sizing, while the separate taper crimp secures projectiles against chamber feeding forces without buckling the cartridge shoulder.

Key Features

• Carbide Expander Button: Integrated free-floating carbide size button minimises brass neck stretch and reduces the need for inside-neck lubrication during full-length resizing.
• Competition Micrometer Seating Die: Features a floating cartridge alignment sleeve that supports the case and projectile prior to seating, with depth adjustments calibrated in 0.001" increments.
• Dedicated Taper Crimp Die: Applies a uniform taper crimp in a separate operation to ensure reliable feeding in semi-automatic actions without distorting the case shoulder.
• Standard Press Mounting: Uses standard 7/8"-14 threading for direct compatibility with Australian-market single-stage and progressive reloading presses.

Who is the Redding National Match 3-Die Set for .30-06 Springfield for?

• Competitive match shooters running semi-automatic platforms — Requires full-length resizing, separate taper crimping, and precision seating in 0.001" increments to ensure flawless feeding and low concentricity runout in gas-operated rifles like the M1 Garand chambered in .30-06 Springfield.
• Precision handloaders loading for bolt-action rifles — Relies on this National Match die set's 7/8"-14 thread interface and 0.001" micrometer seating depth adjustments to achieve minimal projectile runout across standard .30-06 Springfield match brass.

Less suitable for: Other .30 calibre cartridges such as .308 Winchester or .300 Winchester Magnum which require their own calibre-specific dies; handloaders seating very low drag (VLD) extreme ogive bullets who require an optional dedicated VLD seating stem; and handloaders seeking exact neck-tension adjustments without an expander ball, who are better served by a bushing-style match die set.
