The Redding 270 Wby Weatherby Magnum Neck Sizing Die (MPN: 81234) is a Series B reloading die engineered to resize only the case neck and decap spent primers without altering the case body dimensions or pushing back the shoulder. Machined from heat-treated, case-hardened alloy steel, this die preserves the fire-formed chamber fit of .270 Weatherby Magnum brass (.277" diameter bullet) to maximise reload life and maintain cartridge-to-chamber concentricity.

Key Features

  • Neck-Only Resizing: Resizes only the neck portion of the case while maintaining fire-formed body dimensions and shoulder placement.
  • Integrated Decapping Assembly: Includes an internal decapping rod assembly with an expander ball and lock ring for simultaneous depriming and neck expansion.
  • Precision Hardened Steel: Lathe-turned from case-hardened alloy steel to minimise concentricity runout during sizing operations.
  • Standard Press Compatibility: Features an industry-standard 7/8"-14 thread to fit standard single-stage and progressive reloading presses.
  • Component Upgradability: Compatible with optional Redding carbide or tapered expander button upgrades to reduce internal neck friction.

Who is the Redding 270 Wby Weatherby Magnum Neck Sizing Die for?

  • Bolt-action rifle handloaders — Sizes exclusively the case neck for .270 Weatherby Magnum cartridges utilizing a standard 7/8"-14 thread press interface, maintaining fire-formed chamber alignment for precision shooting without overworking the brass.
  • Hunters managing expensive magnum brass — Extends case longevity across repeated firings by eliminating body working on .277" diameter bullet cases, requiring only a compatible Redding #6 or RCBS #4 shellholder to operate.

Less suitable for: Semi-automatic, pump-action, or lever-action firearms, as well as cases that have exceeded 3 to 5 reload cycles where shoulder expansion causes stiff bolt closure; these scenarios require a full-length sizing die or dedicated shoulder bump die to restore factory chamber clearances.
