The Redding .200 Heat-Treated Steel Neck Sizing Bushing (SKU: 73200) is a precision reloading component engineered to size cartridge case necks to an exact external dimension without requiring an internal expander ball. Designed for stationary reloading press setups, it maintains cartridge concentricity and prevents excessive brass work-hardening. Featuring standard 1/2-inch outer diameter and 3/8-inch length dimensions, this bushing is freely interchangeable across all Redding bushing-style dies—including Type S Neck Sizing, Type S Full Length, and Competition Neck Sizing dies—as well as L.E. Wilson-style bushing dies.

Key Features

  • Precise Dimension Control: Delivers an exact 0.200-inch inside diameter to establish uniform case neck tension.
  • Hardened Steel Construction: Heat-treated steel hardened to Rockwell C 60–62 ensures long-term wear resistance and dimensional stability during continuous sizing.
  • Hand-Polished Interior: Micro-finished inner surface limits friction, brass galling, and material buildup when sizing lubricated case necks.
  • Wide Die Compatibility: Built with a 1/2-inch outer diameter that fits standard bushing cavities across multiple precision die systems.
  • Size Identification: Clearly stamped with its 0.200-inch internal dimension for rapid identification on the reloading bench.

Who is the Redding .200 Heat-Treated Steel Neck Sizing Bushing for?

  • Benchrest precision target shooters — requires an exact 0.200-inch inside diameter neck sizing bushing to manage neck tension on small sub-calibre wildcats and precision target cases without inducing concentricity runout from an expander ball.
  • Custom varmint handloaders — benefits from the Rockwell C 60–62 surface hardness and polished internal surface of this neck sizing bushing to minimise neck friction and brass overworking when forming small-calibre cartridges such as .17-calibre and .20-calibre variants.

Less suitable for: Handloaders sizing neck diameters down by more than 0.004 inches to 0.005 inches in a single pass (requiring intermediate step-down bushings or neck turning), or handloaders loading large-calibre cartridges with neck dimensions from 0.367 inches through 0.405 inches, which require larger-format 5/8-inch outer diameter bushing bodies.
