What dies are compatible with the Redding 76329 Titanium Nitride Neck Sizing Bushing?

This bushing features a standard 1/2-inch outer diameter and a 3/8-inch length, allowing it to freely interchange in all Redding Bushing-Style Sizing Dies, such as Type S Bushing Neck and Full Length Sizing Dies. It is also fully compatible with L.E. Wilson-style bushing dies. It is commonly used for precision rifle calibers requiring a .329" sized neck, such as .30 caliber cartridges with specific case neck wall thicknesses.

Are there any specific Australian compliance or electrical certifications required for this Redding bushing?

No. The Redding 76329 is a non-powered mechanical reloading accessory and does not require 240V mains power, an Australian power plug, or SAA/RCM regulatory certification. It is completely unrestricted for Australian consumer purchase, import, and use in your reloading setup.

What preparation or case neck tolerances are required before using the 0.329" Titanium Nitride bushing?

Redding specifies that your cartridge cases should have uniform neck wall thickness for best results. If your case neck wall thickness variation exceeds 0.002", standard single-step bushing sizing will not produce uniform tension, and you will need to perform neck turning or adjust your bushing size accordingly to achieve sub-MOA accuracy.

How does the Titanium Nitride (TiN) coating improve the performance and lifespan of the bushing?

The bushing is manufactured from heat-treated tool steel hardened to approximately Rc 60-62 at the base and finished with an ultra-slick Titanium Nitride surface coating. This hard TiN finish significantly reduces friction and eliminates the risk of brass galling during the sizing process, ensuring consistent neck tension and extending the overall working life of your brass cases.

Neck Sizing Bushing - Redding 76329

The Redding .329 Titanium Nitride Neck Sizing Bushing (MPN 76329) is a precision reloading die component designed to precisely size the outside diameter of cartridge case necks. Crafted from heat-treated tool steel hardened to Rc 60–62 and finished with a Titanium Nitride (TiN) coating, it minimizes friction and reduces the risk of brass galling during the sizing process. By sizing only the case neck to achieve exact neck tension without overworking the brass, it helps maintain bullet concentricity and extends overall cartridge case life.

Key Features

Titanium Nitride Coating: Features a micro-smooth, ultra-hard surface treatment that reduces sizing friction and brass wear.
Standard Fit: Sized with a standard 0.500" outer diameter and 0.375" length to freely interchange across all Redding Bushing-Style Sizing Dies (such as Type S Bushing Neck and Full Length dies) and L.E. Wilson–style bushing dies.
Precision Neck Tension: Accurately sizes case necks to a 0.329 inches inside diameter, commonly utilized for .30 calibre cartridges like .308 Win, .30-06, or .300 Win Mag depending on specific brass wall thickness.
Laser-Engraved Sizing: Marked clearly with its internal diameter for quick identification on the reloading bench.

Who is the Redding .329 Titanium Nitride Neck Sizing Bushing for?

Precision rifle handloaders — provides precise neck sizing down to a 0.329 inches diameter in Redding Type S dies, allowing reloaders to fine-tune bullet release tension for sub-MOA accuracy without overworking brass.
Benchrest shooters — utilizes a hardened Rc 60–62 base tool steel construction with standard 0.500" outer diameter dimensions to maintain maximum bullet concentricity and eliminate brass galling across high-volume load development.

Less suitable for: Cases where neck wall thickness variation exceeds 0.002" requiring neck turning before bushing sizing, or large-calibre cartridges like .338 Lapua Mag and above that exceed standard 0.500" outer diameter dies and require larger-series bushing lines.
