The Redding 6mm BR Remington Type S Bushing Neck Sizing Die (Part Number: 71317) provides precise control over case neck tension and decapping for fire-formed 6mm B.R. Remington cartridge brass. Engineered specifically for precision reloading, this die works only the case neck, leaving the body and fire-formed shoulder dimensions untouched to maintain an exact fit with the rifle's chamber. Mounted via standard 7/8"-14 threads, it supports precision bolt-action rifle shooting by minimising brass fatigue and maximising concentricity.

Key Features

  • Interchangeable Bushing System: Utilises self-centring sizing bushings available in 0.001" increments (sold separately) to precisely set neck tension without overworking cartridge brass.
  • Infinitely Adjustable Sizing Depth: The internal decapping rod assembly allows handloaders to adjust bushing depth to size either the complete neck length or a partial fraction of the neck.
  • Dual Expander Configuration: Includes a steel decapping rod assembly, size button, and a dedicated decapping pin retainer to allow for sizing with or without an expander ball.
  • Standard Press Integration: Built with industry-standard 7/8"-14 die mounting threads compatible with standard single-stage and turret reloading presses.
  • Calibre-Specific Shellholder Fit: Compatible with standard Redding Shellholder #1 (Part #11001) and Competition Shellholder #1 (Part #11601) for .243" projectile diameter 6mm BR cases.

Who is the Redding 6mm BR Type S Neck Bushing Die for?

  • 6mm BR Benchrest and F-Class Precision Handloaders — Sizes case necks with interchangeable bushings adjustable in 0.001" increments, allowing exact neck tension control for consistent bullet release on match brass.
  • Match Shooters Reloading Fire-Formed Brass for Bolt-Action Rifles — Uses an industry-standard 7/8"-14 thread die body to decap and neck-size fired cases without altering the fire-formed case body or shoulder geometry.

Less suitable for: Handloaders processing brass fired across multiple rifles, running semi-automatic platforms, or experiencing bolt-close chambering resistance due to expanded case shoulders; these conditions require a full-length sizing die, small-base die, or a dedicated body die to bump the shoulder back.
