The Redding .199 Heat-Treated Steel Neck Sizing Bushing is a precision reloading component engineered to size cartridge case necks to an exact outside dimension without over-working the brass. Built from heat-treated tool steel hardened to Rockwell C 60–62 (Rc 60–62), this bushing features a hand-polished internal sizing surface to minimise friction and prevent galling. It enables handloaders to achieve precise neck tension and maintain cartridge concentricity without relying on standard expander balls, helping to extend overall brass life.
Key Features
- Precise Neck Tension: Accurately sizes case necks to an exact 0.199-inch inside diameter, providing controlled bullet grip without excessive work-hardening.
- Hardened Tool Steel Construction: Heat-treated to Rockwell C 60–62 (Rc 60–62) for long-term wear resistance under repetitive sizing pressure.
- Hand-Polished Interior: Features a smooth internal finish that reduces sizing effort and protects brass surfaces when used with standard case neck lubricant.
- Standardised Sizing Dimensions: Manufactured with industry-standard 1/2-inch (0.500-inch) outside diameter and 3/8-inch (0.375-inch) length dimensions for broad die compatibility.
- Universal System Compatibility: Fully interchangeable across Redding Type S Neck Sizing Dies, Type S Full Length Dies, Competition Bushing Neck Sizing Dies, and standard Wilson-style bushing dies.

Who is the Redding .199 Heat-Treated Steel Neck Sizing Bushing for?
- Precision target shooters — Requires precise 0.199-inch outer neck dimensions on sub-calibre target brass, utilising this neck sizing bushing's Rockwell C 60–62 hardened steel construction to maintain uniform bullet release and tight concentricity.
- Varmint hunters — Sizes small-capacity brass for cartridges like the .17 Hornet, .17 Fireball, and .17 Remington, relying on this 0.199-inch inside diameter neck bushing to set exact neck tension without over-working thin case necks.
- Wildcat handloaders — Forming custom tight-neck sub-calibre cases that require a specific 0.199-inch finished neck diameter within standard 0.500-inch outside diameter die channels.
Less suitable for: High-volume continuous reloading runs where reduced surface friction is critical (which are better served by Titanium Nitride / TiN coated neck bushings), or operations requiring brass neck reduction greater than 0.004 to 0.005 inches in a single pass (which require intermediate step-down sizing bushings to prevent neck distortion).
