The Redding .289 Heat-Treated Steel Neck Sizing Bushing (MPN: 73289) is a precision reloading component engineered to size cartridge case necks to precise outer dimensions. By sizing only the outside diameter of the case neck, it eliminates the need for an expander ball to pull through the brass, controlling neck tension while preventing excessive working of the metal. Manufactured from hardened, heat-treated steel with a hand-polished interior bore, it minimizes sizing resistance and brass runout during operation.
Key Features
- Precise Neck Tension Control: Directly sizes the outer case neck diameter down to 0.289 inches to yield uniform bullet release consistency and reduce neck runout.
- Extended Brass Longevity: Prevents over-working of the cartridge brass by avoiding internal expander balls during the sizing stroke.
- Hand-Polished Interior Bore: Finished with a polished internal surface to reduce friction and eliminate galling on lubricated case necks.
- Broad Die Compatibility: Freely interchanges with all Redding Type S Neck Sizing Dies, Type S Full Length Sizing Dies, Redding Competition Bushing Neck Dies, and standard Wilson-style neck sizing dies.

Who is the Redding .289 Heat-Treated Steel Neck Sizing Bushing for?
- Precision 6.5mm Handloaders — Requires a 0.289 inch internal sizing diameter to achieve precise 0.001 to 0.002-inch neck tension on loaded cartridges measuring 0.290 to 0.291 inches, commonly used for calibres such as 6.5 Creedmoor, 6.5x47 Lapua, and .260 Remington using this steel neck sizing bushing.
Less suitable for: Reloaders seeking a lubrication-free sizing process, who should use a Titanium Nitride (TiN) coated bushing, or cases requiring more than 0.004 inches to 0.005 inches of total neck diameter reduction, which requires intermediate stepping using multiple progressive bushing sizes to prevent brass distortion.
