The Redding Type S – Bushing Neck Sizing Die (MPN: 71136) is a precision reloading tool designed for 7mm Remington Magnum cartridges (.284" bullet diameter). Engineered for single-rifle bolt-action setups, this die sizes fire-formed cartridge case necks while preserving the fire-formed dimensions of the case body and shoulder. By utilizing freely floating, interchangeable sizing bushings (sold separately, typically ranging from .305" to .313" for this calibre), the die self-centres on the case neck axis to minimise runout, maintain concentricity, and eliminate overworking of brass.

Key Features

  • Interchangeable Bushing System: Accepts standard Redding steel or titanium nitride (TiN) bushings adjustable in .001" increments to establish exact neck tension.
  • Self-Centring Alignment: The freely floating bushing design self-aligns with the cartridge neck axis during the sizing stroke to optimise concentricity.
  • Dual Decapping Modes: Includes a standard size expander button for commercial unturned brass as well as a decapping pin retainer for turned match brass, allowing decapping without drawing an expander through the neck.
  • Selective Sizing Depth: The adjustable decapping rod assembly enables handloaders to size the complete neck or only a partial length of the neck.
  • Standard Press Integration: Features industry-standard 7/8"-14 die threading with an included locking ring to fit standard single-stage and turret reloading presses.

Who is the Redding 7mm Rem Mag Type S - Neck Die for?

  • Long-range precision handloaders — requires exact neck tension control for .284" diameter projectiles using interchangeable bushings in .001" increments to extend brass life and minimise runout on fire-formed 7mm Remington Magnum cases.
  • Benchrest competitors — handloading fire-formed 7mm Remington Magnum brass on standard 7/8"-14 threaded presses who require the ability to decap and size turned case necks without dragging an expander ball through the neck.

Less suitable for: Handloaders processing brass that has reached 3 to 5 firings where body expansion and shoulder migration cause stiff bolt closure, or shooters using semi-automatic, pump, or lever-action actions; these conditions require switching to a full-length sizing die or dedicated body die to bump the shoulder and resize the case body.
