The Redding 308 Win Type S - Neck Die (Model 71155) provides precise neck tension control and decapping for fire-formed .308 Winchester cartridge cases. Designed with a floating, interchangeable bushing system, this mechanical die sizes only the case neck to user-selected dimensions while leaving the fire-formed case body and shoulder dimensions undisturbed to maintain chamber fit and extend brass life.

Key Features

  • Interchangeable Bushing System: Accepts Redding steel or titanium nitride sizing bushings (sold separately) to adjust neck tension in increments of 0.001".
  • Self-Centering Floating Design: Allows the sizing bushing to float freely within the die body, self-centering on the case neck to minimise runout and improve concentricity.
  • Adjustable Decapping Assembly: Permits vertical adjustment of the decapping pin to enable full-length neck sizing or partial neck sizing.
  • Configurable Expander Ball: Includes a standard steel expander button that can be retained for neck-tension uniforming or removed for minimal brass working with neck-turned brass.
  • Standard Press Fitment: Machined with industry-standard 7/8"-14 threads to mount directly into standard single-stage and progressive reloading presses.

Specifications

  • Cartridge Compatibility: .308 Winchester (accepts .308" diameter projectiles)
  • Thread Interface: Standard 7/8"-14 reloading press threading
  • Shellholder Fitment: Requires standard Redding #1 Shellholder (#11001) or Competition Shellholder #1 (#11601) (sold separately)
  • Bushing Range Compatibility: Accepts standard Redding sizing bushings (typically 0.333" to 0.341" for .308 Winchester)
  • Operation: Fully mechanical, manual reloading press operation

Who is the Redding 308 Win Type S - Neck Die for?

  • Precision bolt-action rifle reloaders seeking minimum runout — mounts into standard 7/8"-14 reloading presses and uses a floating bushing system to size fire-formed .308 Winchester necks without altering body dimensions, maximising concentricity.
  • Handloaders dedicating fire-formed brass to a single rifle chamber — provides neck-only resizing for .308 Winchester cases, maintaining the exact fire-formed shoulder profile to increase case life across multiple firings.

Less suitable for: Handloaders loading for semi-automatic rifles, lever-action rifles, or multiple different firearms, where full-length sizing dies or small base sizing dies are required to ensure reliable feeding; and brass exceeding 3 to 5 reload cycles where shoulder growth causes chambering resistance, requiring a dedicated body die or full-length sizing die to bump the shoulder back.
