What sizing dies are compatible with the Redding 7.316 Titanium Nitride Neck Sizing Bushing?

This bushing features a standard 1/2-inch outer diameter (0.500") and a 3/8-inch length (0.375"). It freely fits and interchanges across all Redding Bushing-style Full Length and Neck Sizing Dies, including Type S and Competition series, as well as L.E. Wilson bushing-style sizing dies.

How do I determine if the 0.316-inch size is correct for my specific handloads?

To select the correct bushing size, measure the outside neck diameter of a loaded dummy round using precision calipers or micrometers and subtract 0.001" to 0.002" for proper neck tension. The 0.316" size is typically chosen for loaded cartridges measuring approximately 0.317" to 0.318" across various 7mm or .30-caliber configurations.

Do I need any special permits or firearms licensing to purchase this reloading component in Australia?

No special permits or firearms licenses are required for possession or purchase of this product in Australia. As a purely mechanical reloading tool component with zero electrical parts, it is freely imported and retailed across the country.

What are the advantages of the Titanium Nitride (TiN) coating over standard steel bushings?

The precision-machined, heat-treated steel base is enhanced with a gold-colored Titanium Nitride surface coating hardened to approximately Rc 60–62. This TiN treatment significantly increases surface hardness and lowers friction during the sizing stroke, helping to extend brass case life and eliminate the need for expander balls.

Neck Sizing Bushing - Redding 76316

The Redding .316 Titanium Nitride Neck Sizing Bushing (MPN 76316) is a precision reloading component engineered to size cartridge case necks to an exact inside diameter of 0.316 inches. Built on a heat-treated steel base hardened to approximately Rc 60–62 and finished with a hand-polished Titanium Nitride (TiN) coating, this bushing provides precise neck tension without overworking the brass or requiring an expander ball. It features standard exterior dimensions of a 1/2-inch outer diameter (0.500") by a 3/8-inch length (0.375"), allowing it to interchange freely across all Redding Type S Bushing Dies, Competition Bushing Dies, and compatible L.E. Wilson bushing-style sizing dies.

Who is the Redding .316 Titanium Nitride Neck Sizing Bushing for?

Precision handloaders assembling target shooting and long-range benchrest ammunition — Requires setting an exact 0.001" to 0.002" of neck tension on cartridge cases with loaded neck diameters measuring 0.317" to 0.318" using this 0.316-inch diameter Titanium Nitride neck sizing bushing.
Handloaders creating precision hunting handloads requiring exact neck tension — Relies on the standard 0.500-inch outer diameter and 0.375-inch length form factor to size brass consistently across standard-calibre Redding Type S and Competition sizing dies.

Less suitable for: Handloaders assembling large-magnum calibres requiring neck bushing sizes from 0.369 inches to 0.405 inches (such as .338 Lapua Magnum), which exceed standard 1/2-inch dies and require large-diameter steel sizing bushings with a 5/8-inch outer diameter and 1/2-inch length.
