The Redding 77317 Type S Full Length Bushing Die is engineered for precision handloading of 6mm BR Remington and 6mm Norma BR cartridges (.243 in / 6mm bullet diameter). It resizes the entire cartridge case body and sets headspace back to specification while offering precise control over case neck diameter in a single press stroke. Constructed from heat-treated carbon steel, the die incorporates a floating bushing pocket that allows interchangeable sizing bushings to self-centre on the cartridge neck, minimising runout and maintaining concentricity across high-volume reloading cycles.

Key Features

  • Full-Length Sizing with Neck Adjustment: Restores factory case body dimensions and bumps the shoulder back while sizing the neck to user-selected diameters.
  • Self-Centring Bushing System: The floating neck bushing pocket aligns itself automatically with the case neck to optimise concentricity.
  • Dual De-priming Configurations: Includes a standard steel expander button (#39242) for sizing standard brass, as well as a decapping pin retainer for sizing uniform or neck-turned brass without an expander ball to prevent excessive work-hardening.
  • Adjustable Sizing Depth: The decapping rod assembly (#10242) adjusts vertically to allow full-length neck sizing or partial neck sizing.
  • Industry-Standard Mounting: Machined with standard 7/8"-14 threads to interface directly with standard reloading presses.

Who is the Redding Type S Full Length Bushing Die for?

  • 6mm BR benchrest competition shooters — requires precise neck tension adjustment down to 0.001" increments using interchangeable bushings to achieve minimal runout and tight group tolerances with 6mm BR full-length sizing dies.
  • Precision rifle series handloaders — requires consistent case chambering and reliability via a 7/8"-14 thread press interface paired with a #1 shellholder to run full-length body sizing alongside dedicated neck tension control.

Less suitable for: Handloaders running unlubricated cases; adequate case lubrication is strictly required prior to full-length sizing to avoid stuck cases, and reloaders seeking small-base sizing for tight semi-automatic chambers require a dedicated small base full-length sizing die.
