The Redding Type S-Match Bushing Neck Die Set (MPN 38443) is a precision three-die reloading system engineered for 6mm Creedmoor (.243 in / 6mm projectile diameter) cartridges. Designed specifically for handloaders working with fire-formed brass from bolt-action rifles, this set maximizes concentricity, minimizes projectile runout, and extends case life. The set includes a Type S Bushing Neck Sizing Die, a dedicated Body Die, and a Competition Bullet Seating Die, all built with standard 7/8"-14 threading to fit standard Australian reloading bench presses.

Key Features

• Type S Bushing Neck Die: Utilises interchangeable sizing bushings (available separately in 0.001" increments) and an adjustable decapping rod assembly to size the full neck or partial neck length without overworking the brass.
• Dedicated Body Die: Resizes the case body and bumps the shoulder back 0.001"–0.002" when chamber fit resistance develops, without contacting or altering the prepared neck dimensions.
• Competition Seating Die: Features a patented sliding internal alignment sleeve that centers the bullet and case before seating, paired with a micrometer head graduated in precise 0.001" increments for repeatable seating depths.
• Three-Piece Configuration: Ships in a hard plastic storage box with a packaged weight of approximately 0.65–0.75 kg.

• Required Shellholder: Redding #1 Shellholder (PN: 11001) or Redding Competition Shellholder #1 (PN: 11601) (sold separately)
• Operating Mechanism: Completely mechanical manual reloading tooling

Who is the Redding Type S Match Bushing Neck Die Set for?

• Long-range precision rifle competitors — Sizes 6mm Creedmoor brass using interchangeable bushings adjustable in 0.001" increments to achieve minimal projectile runout and single-digit velocity standard deviations across 100 m to 1,000+ m targets.
• Benchrest and target handloaders — Uses a Competition Seating Die with a micrometer top calibrated in 0.001" increments on standard 7/8"-14 presses to maintain exact bullet seating depth and strict cartridge concentricity.
• Precision bolt-action reloaders — Preserves fire-formed case geometry across repeated firings by neck-sizing 6mm diameter cases and bumping shoulders using the included separate body die only when chamber resistance occurs.

Less suitable for: Semi-automatic rifles (gas guns) or ammunition fired across multiple distinct chambers; these require a full-length sizing die set (such as a Type S Match Bushing Full Die Set) to ensure reliable feeding and extraction.
