The Redding Type S – Bushing Style Neck Sizing Die for .300 PRC (MPN: 71776) is engineered for precision metallic reloading, allowing handloaders to resize cartridge case necks while preserving the fire-formed dimensions of the case body. Built from heat-treated alloy steel and machined to standard 7/8"-14 TPI press mounting threads, this die uses interchangeable neck bushings adjustable in 0.001" increments to establish precise neck tension without overworking the brass. The self-centering bushing floats within the die cap to minimise runout and improve bullet concentricity. It includes a complete decapping rod assembly with a .30 calibre size button and a decapping pin retainer for buttonless neck sizing.

Key Features

  • Interchangeable Bushing System: Accepts interchangeable sizing bushings (available in 0.001" increments) to allow exact control over case neck tension and extend brass case life.
  • Self-Centering Floating Design: The bushing floats freely inside the die pocket during the sizing stroke, self-aligning to the case neck to minimise concentricity runout.
  • Adjustable Sizing Depth: The decapping assembly allows reloaders to adjust the bushing position to size either the entire neck length or only a partial section.
  • Configurable Decapping Assembly: Ships with both an expander size button for commercial brass and a decapping pin retainer for buttonless sizing of uniform or neck-turned brass.

Who is the Redding .300 PRC Type S Neck Die for?

  • Long-Range Precision Rifle Reloaders — Requires exact neck tension control for .308 in (7.82 mm) bullets using interchangeable bushings in 0.001" increments to minimise brass work-hardening across repeated firings in standard 7/8"-14 TPI reloading presses.
  • F-Class and ELR Competitors — Requires a 300 PRC neck sizing die that maintains the fire-formed body dimensions of dedicated chamber brass, using a floating bushing pocket to minimise neck runout for extreme-distance consistency beyond 1,000 yards.

Less suitable for: Handloaders whose fired cases have expanded after 3 to 5 firings and exhibit heavy bolt lift or chambering resistance; in these conditions, a full-length sizing die or dedicated body die is required to bump shoulders and restore body clearance.
