The Redding 7mm PRC Neck Sizing Die (Model 81936) is a precision reloading tool designed specifically for resizing the case neck of fired 7mm Precision Rifle Cartridge brass. Engineered with industry-standard 7/8"-14 threads, it mounts directly into standard single-stage and turret reloading presses. By sizing only the neck and leaving the fire-formed case body and shoulder untouched, this die preserves the precise dimensions of cases fired in a dedicated bolt-action chamber, minimising brass work-hardening and maximizing alignment concentricity for improved downrange accuracy.

Key Features

  • Neck-Only Resizing: Resizes exclusively the neck portion of 7mm PRC brass without bumping the shoulder or altering body dimensions, maintaining custom fire-formed fit.
  • Integrated Decapping Assembly: Includes a decapping rod with a replaceable pin and an expander ball size button to remove spent primers and set uniform inside neck diameter on the press upstroke.
  • Extended Brass Longevity: Prevents unnecessary working of the case wall brass, directly reducing work-hardening to yield more reload cycles per case.
  • Standard Thread Mounting: Machined with 7/8"-14 threads for direct compatibility across standard Australian workshop reloading presses without requiring specialised adapters.

Who is the Redding 7mm PRC Neck Sizing Die for?

  • Precision handloaders shooting dedicated bolt-action rifles — sizes only the neck of 7mm PRC cases to preserve exact fire-formed chamber dimensions across standard 7/8"-14 thread single-stage or turret presses.
  • Long-range target shooters seeking maximum brass longevity — eliminates continuous working of the case body and shoulder on 7mm PRC bottleneck brass, reducing metal fatigue across consecutive reload cycles.

Less suitable for: Handloaders experiencing chambering resistance after 3 to 5 firings due to normal case body expansion and shoulder growth, who require a full-length sizing die or dedicated body die to bump headspace back; shooters loading for semi-automatic or lever-action actions where full-length resizing is necessary for reliable feeding; or reloaders wanting custom neck-tension adjustments in precise .001" increments, who require a bushing-based neck sizing die.
