What dies are compatible with the Redding .265 Heat-Treated Steel Neck Sizing Bushing?

This bushing freely interchanges across all Redding Bushing Dies, including Type S Bushing Full Length Dies, Type S Neck Sizing Dies, Competition Bushing Neck Sizing Dies, as well as standard Wilson and L.E. Wilson style bushing neck dies.

Do I need to lubricate case necks when using this heat-treated steel bushing?

Yes, because this variant is made from plain heat-treated steel rather than being titanium nitride coated, external case neck lubrication such as dry lube, mica, or sizing wax is required to prevent brass galling during the sizing process.

What is the maximum recommended sizing reduction in a single pass with this .265 bushing?

Redding recommends sizing down in increments of no more than .004 to .005 inches in a single pass. If your fire-formed brass requires a larger reduction, you should use a multi-step reduction with intermediate bushings to avoid crushing the case shoulder.

Are there any electrical compliance or SAA/RCM regulatory approvals required for use in Australia?

No electrical compliance or regulatory certifications are required. This is a fully mechanical, non-powered reloading component, meaning 240V power, Australian AC plugs, and SAA/RCM approvals do not apply.

Neck Sizing Bushing - Redding 73265

The Redding .265 Heat-Treated Steel Neck Sizing Bushing (MPN: 73265) provides precise control over cartridge case neck tension without the use of an expander ball. Machined from high-grade steel and hardened to Rockwell Rc 60–62, this bushing features a hand-polished interior bore with a manufacturing tolerance of +0.0005" / -0.0000". Sizing the exterior case neck to a specific 0.265-inch diameter prevents excessive brass working, minimises work-hardening, and helps maintain concentricity across repeated firings. Case neck lubrication is required during operation to prevent galling.

Key Features

Precise Neck Sizing: Sets outer neck diameter to exactly 0.265 inches (approx. 6.73 mm), allowing reloaders to precisely calibrate neck tension (typically .001" to .003") without overworking brass.
Hardened Steel Construction: Heat-treated to a hardness of Rockwell Rc 60–62 and finished with a hand-polished bore for smooth cycling and extended service life.
Universal Cavity Compatibility: Features a standard 0.500" outer diameter (approx. 1/2" profile), ensuring direct interchangeability across all Redding Type S and Competition bushing dies, as well as standard Wilson-style bushing dies.
Size Identification: Laser-marked with its .265 designation for rapid identification on the reloading bench.

Who is the Redding .265 Heat-Treated Steel Neck Sizing Bushing for?

Precision rifle competitors — requires an exact 0.265-inch sizing diameter to establish consistent neck tension on loaded cartridges measuring .266" to .267" outer neck diameter without inducing runout.
Benchrest reloaders — benefits from the Rockwell Rc 60–62 hardened steel construction and hand-polished interior bore to extend cartridge brass life and prevent concentricity issues across high-volume firing cycles.
Handloaders utilizing Redding bushing dies — uses the standardized 0.500" outer diameter format to freely interchange sizing components across Redding Type S Full Length, Type S Neck, and Competition bushing dies.

Less suitable for: Applications requiring a neck diameter reduction exceeding .004" to .005" in a single pass; situations with larger dimensional changes require intermediate-step sizing bushings to prevent crushing the cartridge case shoulder, or titanium nitride (TiN) coated bushings if operating without external neck lubrication.
