The Redding Type S – Bushing Neck Sizing Die (.303 British, MPN: 71154) is a reloading tool engineered to precisely resize the necks of fire-formed cartridge brass while leaving the case body and shoulder untouched. Designed for standard reloading presses featuring industry-standard 7/8"-14 threads, this die uses freely floating, interchangeable bushings to optimize neck tension and cartridge concentricity. It is built to extend brass life and maintain fire-formed chamber dimensions for bolt-action rifles chambered in .303 British (nominal bullet diameter: 0.311 in / 7.90 mm).

Key Features

  • Interchangeable Bushing System: Utilises freely floating Redding sizing bushings (available in 0.001" increments across a 0.328 in to 0.336 in range) that self-centre on the case neck for improved concentricity.
  • Dual Operation Modes: Includes an expander size button (#40310) for commercial cases with variable wall thickness, alongside a decapping pin retainer (#10196) for buttonless sizing that eliminates neck stretch on uniform brass.
  • Adjustable Sizing Depth: The decapping rod assembly allows exact vertical positioning of the bushing to size either the full neck length or a partial section.
  • Chamber Integrity: Resizes only the neck of the cartridge, preserving fire-formed body taper and shoulder datum to prolong case life.

Who is the Redding 303 British Type S - Neck Die for?

  • Australian Historic Service Rifle Competitors in SSAA Military Rifle Matches — Utilises 0.328 in to 0.336 in interchangeable bushings in this Type S neck sizing die to minimise brass working and maintain precise cartridge concentricity for Lee-Enfield and P14 service rifles.
  • Hunters and Target Shooters Running Bolt-Action .303 British Rifles — Threads into standard 7/8"-14 reloading presses to size fire-formed .303 British case necks without altering the shoulder datum, maximizing brass life and shot-to-shot consistency in dedicated rifle chambers.

Less suitable for: Reloading brass intended for semi-automatic or lever-action firearms, cartridges shared across multiple different rifles, or brass that has undergone 3 to 5 firing cycles resulting in expanded shoulders and stiff bolt closure; these applications require a full-length resizing die or a dedicated body die.
