The Redding .285 Titanium Nitride Neck Sizing Bushing (MPN 76285) is a precision reloading component engineered to size cartridge case necks to an exact inside diameter of 0.285 inches. By sizing the exterior of the case neck without the use of a standard expander ball, it prevents unnecessary brass working, reduces neck runout, and extends overall cartridge brass life. Constructed from heat-treated steel coated in a durable Titanium Nitride (TiN) surface finish, this bushing reduces friction and resists brass galling during the sizing stroke. It features standard 0.500" outer diameter dimensions and a 0.375" length, making it compatible with Redding Type S Neck Sizing Dies, Type S Full Length Sizing Dies, and Redding Competition Bushing Dies, as well as standard 1/2-inch bushing-die systems from RCBS, Hornady, and L.E. Wilson.

Key Features

  • Precise Neck Tension: Establishes a controlled 0.285-inch outside neck dimension to optimize bullet grip and maximize concentricity across loaded rounds.
  • Titanium Nitride Coating: Hard TiN gold finish delivers high surface lubricity, minimizing sizing effort and lowering the risk of brass pickup.
  • Expander-Free Sizing: Eliminates the case-stretching effects of traditional internal expander balls to prevent brass fatigue and minimize neck runout.
  • Standardized Fit: Measures 0.500" in outer diameter and 0.375" in length for broad interchangeability across standard 1/2-inch bushing dies.
  • Size Stamped: Laser-etched or stamped with its 0.285" inside dimension for quick identification on the reloading bench.

Who is the Redding .285 Titanium Nitride Neck Sizing Bushing for?

  • Precision rifle competition handloaders — Sizes case necks to an exact 0.285-inch inside diameter within standard 0.500" outer diameter Type S dies, providing precise bullet tension control and eliminating expander ball runout for competition-grade concentricity.
  • Long-range hunting ammunition developers — Delivers a consistent 0.285-inch neck dimension using a low-friction 0.375" length Titanium Nitride neck sizing bushing, reducing brass work-hardening across repeated high-pressure reloads for field ammunition.

Less suitable for: Cartridge setups where the loaded outside neck diameter falls outside the ~0.286" to 0.287" target window (which requires selecting a different increment from an alternate-diameter bushing range) or reloaders using proprietary-dimension sizing dies that do not accept standard 0.500" outer diameter bushings.
