The Redding .35 Whelen Neck Sizing Die (MPN: 81215) is a precision reloading tool engineered to resize only the neck of fire-formed cartridge cases while leaving the case body and shoulder dimensions undisturbed. Designed for reloaders who fire ammunition repeatedly through a single rifle, this die preserves the exact fire-formed fit of the brass to the rifle chamber. By eliminating unnecessary working of the cartridge body, it reduces brass work-hardening and extends case life. The die features standard 7/8"-14 threading for universal compatibility with standard single-stage and turret reloading presses, and it performs decapping and neck expansion in a single mechanical stroke.

Key Features

  • Neck-Only Sizing: Resizes the neck to hold standard .358 in (9.1 mm) diameter bullets while maintaining the fire-formed body shape for chamber alignment.
  • Integrated Decapping and Expanding: Features decapping rod assembly #24356, expander button #16356, and decapping pin #01060 to deprime and set internal neck tension simultaneously.
  • Extended Brass Life: Minimises brass fatigue by avoiding full-length body sizing on every reload cycle.
  • Standard Press Mounting: Uses an industry-standard 7/8"-14 thread pitch with knurled lock ring #01016 for secure setup across compatible reloading presses.

Who is the Redding 35 Whelen Neck Sizing Die for?

  • Bolt-action target shooters loading for .35 Whelen — requires this neck sizing die to maintain precise chamber alignment and correct neck tension for standard .358 in (9.1 mm) diameter bullets across repeated firings in a single rifle.
  • Hunters reloading .35 Whelen ammunition for a single specific firearm — benefits from this neck sizing die mounted in a standard 7/8"-14 thread press to maximise brass life and ensure consistent ammunition dimensions fire-formed to that specific chamber.

Less suitable for: Semi-automatic, pump-action, or lever-action rifles, or reloaders cycling brass across multiple rifles, where cases that expand after 3 to 5 firings create tight bolt closure and instead require a standard full-length sizing die.
