What die compatibility does the Redding 76306 Titanium Nitride Neck Sizing Bushing have in my reloading setup?

The Redding 76306 bushing features standard external dimensions of a 1/2-inch outer diameter and a 3/8-inch length. It is designed to freely interchange across all Redding Bushing-Style Dies, including Type S Bushing Neck Sizing and Full Length Sizing dies, as well as compatible bushing dies from L.E. Wilson, RCBS, and Hornady.

How does the Titanium Nitride coating on the 76306 bushing improve performance during high-volume handloading?

The physical vapour deposition Titanium Nitride (TiN) coating raises the surface hardness of the Rc 60-62 heat-treated steel base, significantly reducing sizing friction. This lowers operating effort, minimizes wear on both the bushing and case brass, and helps extend your brass life for precision shooting.

Are there any specific licensing or electrical compliance requirements for purchasing this bushing in Australia?

As a non-powered, mechanical reloading tool component, the Redding 76306 bushing requires no electrical compliance, Australian plugs, or RCM/SAA certifications. It is fully legal and unrestricted for sale across all Australian states and territories for precision handloaders.

What maintenance or lubrication is recommended when operating the Redding 76306 TiN bushing in the workshop?

Although the Titanium Nitride coating drastically reduces friction, Redding explicitly recommends applying a light case neck lubrication during operation. This prevents galling, protects your brass, and ensures maximum service life for the tool during repeated reloading sessions.

Titanium Neck Bushing - Redding 76306

The Redding .306 Titanium Nitride Neck Sizing Bushing (MPN: 76306) is a precision handloading component designed to size cartridge case necks to an exact outer diameter. Machined from steel heat-treated to Rc 60–62 and finished with a physical vapour deposition (PVD) Titanium Nitride (TiN) coating, it reduces sizing friction and prevents overworking the brass. Sizing case necks to exact tolerances ensures uniform neck tension, improving projectile concentricity and shot-to-shot consistency for precision shooting applications.

Key Features

Precise Neck Tension: Calibrated to a 0.306-inch inside diameter to provide exact neck tension without over-working the brass, extending cartridge case life.
Titanium Nitride Coating: Features a PVD TiN hard coating over an Rc 60–62 heat-treated steel core, increasing surface hardness and lowering friction during sizing.
Universal Interface: Standard 1/2-inch outer diameter fits all Redding Bushing-Style Dies (including Type S Neck Sizing and Type S Full Length dies) as well as compatible bushing dies from L.E. Wilson, RCBS, and Hornady.
Hand-Polished Finish: Hand-polished prior to coating to ensure smooth sizing operation when used with light neck lubrication.

Who is the Redding .306 Titanium Nitride Neck Sizing Bushing for?

Precision rifle handloaders — requires an exact 0.306-inch internal diameter titanium nitride neck sizing bushing to avoid over-working case brass and extend reloadable case life.
PRS competitors — relies on the 0.306-inch sizing dimension and low-friction TiN coating over Rc 60–62 hardened steel to achieve consistent neck tension and minimise group sizes.

Less suitable for: Cartridge brass setups where neck-wall thickness variations dictate a dimension other than 0.306 inches; reloaders requiring alternative neck diameters should select alternative bushing sizes available in 0.001-inch increments ranging from 0.185 inches through 0.368 inches.
