The Redding Type S – Bushing Style Neck Sizing Die (MPN: 71241) is a precision reloading tool engineered to size the case neck of 7mm Bench Rest Remington (7mm BR Rem) cartridges without altering the fire-formed body dimensions. Machined from heat-treated alloy steel, this die utilises freely floating, self-centring bushings to control external neck tension in precise increments. Sizing only the neck preserves the cartridge's custom fit to a specific chamber, extending case life and maintaining minimal bullet runout for match-grade consistency.

Key Features

  • Interchangeable Bushing System: Accepts self-centring steel or titanium-nitride (TiN) bushings (available in 0.001-inch increments) to set exact neck tension without overworking cartridge brass.
  • Adjustable Decapping Assembly: Permits full-length or partial neck resizing, allowing reloaders to leave the shoulder-neck junction undisturbed if desired.
  • Dual Operation Modes: Includes a standard expander button for commercial un-turned brass, as well as a decapping pin retainer to eliminate internal sizing entirely when preparing neck-turned match cases.
  • Heat-Treated Steel Construction: Machined to tight tolerances from durable alloy steel for reliable mechanical repeatability on the reloading bench.

Who is the Redding 7mm BR Remington Type S Neck Die for?

  • Precision handloaders shooting 7mm BR bolt-action or single-shot firearms — requires precise calibration of neck tension for .284 in (7.21 mm) bullet diameters via interchangeable bushings while maintaining the fire-formed headspace of a dedicated chamber using standard 7/8"-14 TPI presses.
  • Benchrest and metallic silhouette target shooters — reduces brass fatigue and minimises cartridge runout by resizing only the neck of .284 in (7.21 mm) diameter 7mm BR cases, prolonging the usable life of match-prepared brass.

Less suitable for: Cartridges used across multiple firearms, brass fed through semi-automatic actions, or cases that have expanded to cause heavy bolt lift and tight extraction; these boundary conditions require a dedicated full-length sizing die or a separate body die to bump the shoulder back 0.001" to 0.002" and restore factory body clearances.
