The Redding Competition Bushing Neck Sizing Die (SKU: 56111) is a micro-adjustable reloading die engineered specifically for fire-formed .223 Remington and 5.56×45mm NATO cartridge brass. Built from heat-treated alloy steel, it utilizes a free-floating neck bushing system and an internal sliding alignment sleeve that fully supports the cartridge body before sizing begins. This design eliminates the need for an expander ball, preventing brass work-hardening while centering the case to produce tight concentricity and minimal bullet runout on standard 7/8"-14 threaded reloading presses.

Key Features

  • Sliding Alignment Sleeve: Encases and aligns the entire cartridge body prior to neck sizing to ensure optimal concentricity between the case neck and body axis.
  • Free-Floating Bushing Design: Accommodates standard interchangeable Redding neck sizing bushings to set precise neck tension without an expander ball, extending brass life.
  • Micrometer Depth Adjustment: Features a top-mounted micrometer head calibrated in 0.001" increments to control the exact length of the neck being sized.
  • Durable Construction: Fabricated from precision-machined, heat-treated alloy steel for long-term wear resistance during high-volume precision reloading.

Who is the Redding 223 Rem Competition Neck Die for?

  • Precision benchrest shooters — Requires the 0.001" micrometer adjustment increments on this competition neck sizing die to precisely control neck sizing depth and tension for tight group consistency in .223 Remington chambers.
  • F-Class and long-range target shooters — Relies on the sliding alignment sleeve to maintain minimal case runout when preparing .223 Remington or 5.56×45mm NATO fire-formed brass on standard 7/8"-14 threaded presses.
  • Precision varmint reloaders — Uses the free-floating bushing design to eliminate expander-ball brass stretching, maximizing the working life of high-volume .223 Remington cartridge cases.

Less suitable for: Reloaders experiencing stiff bolt closure due to shoulder growth, or those loading for semi-automatic, pump-action, or lever-action rifles; switch to a full-length bushing sizing die or dedicated body die to properly restore factory case body dimensions and bump the shoulder.
