The Redding .281 Titanium Nitride Neck Sizing Bushing (Model 76281) is a precision reloading component engineered to set exact cartridge case neck diameter and neck tension in 0.001-inch increments. Machined from a heat-treated steel core with a base hardness of Rc 60–62, this bushing features a hand-polished interior finished with a gold-coloured Titanium Nitride (TiN) surface coating. This coating increases surface hardness, minimises brass galling, and reduces friction during sizing. Built to standard external dimensions of 0.500 inches (1/2") outer diameter by 0.375 inches (3/8") in length, it allows reloaders using bushing-style dies to size brass necks from the outside without requiring an expander ball, preserving brass concentricity and prolonging case life.

Key Features

  • Precise Neck Sizing: Delivers an exact 0.281-inch internal diameter, allowing precision control over neck tension and reducing brass fatigue compared to standard expander buttons.
  • Titanium Nitride Coating: Features a specialised TiN surface application that lowers sizing friction, prevents brass transfer, and provides high wear resistance over an Rc 60–62 steel substrate.
  • Wide Die Compatibility: Fits all standard Redding Type S Bushing Neck Sizing Dies, Type S Full Length Sizing Dies, Competition Bushing Neck Sizing Dies, and Wilson-style neck bushing dies.
  • Enhanced Concentricity: Freely centers within compatible sizing dies to size cartridge case necks uniformly without distorting case shoulders or bodies.

Who is the Redding .281 Titanium Nitride Neck Sizing Bushing for?

  • Precision rifle reloaders — requiring a specific 0.281-inch internal diameter neck sizing bushing to achieve exact, repeatable case neck tension without overworking cartridge brass.
  • Benchrest competitors and long-range hunters — sizing calibres such as 6.5mm Creedmoor, 6.5x47 Lapua, .260 Remington, or 6mm variants using Redding Type S dies that match standard 0.500-inch outer diameter and 0.375-inch length bushing dimensions.

Less suitable for: Cartridge cases with neck wall thickness variations exceeding 0.002 inches, where a smaller bushing or dedicated neck-turning tooling is required to establish consistent concentricity.
