What dies are compatible with the Redding 73220 neck sizing bushing?

The Redding 73220 bushing features a standard 1/2-inch outer diameter and a 3/8-inch length. It is specifically designed to fit all Redding Bushing-Style Sizing Dies, including Type S Bushing Neck Sizing Dies and Type S Full Length Dies, and also interchangeably fits standard Wilson-style neck bushing dies.

Do I need any special permits or firearms licences to purchase this bushing in Australia?

No. As a purely mechanical reloading tool component, this bushing is a non-controlled accessory across all Australian states and territories. You do not require a firearms licence endorsement or special permits to purchase, possess, or use it.

How do I determine if the 0.220-inch sizing diameter is correct for my specific cartridge?

To select the correct size, measure the outside neck diameter of your loaded round with calipers and subtract 0.001 to 0.002 inches to account for proper neck tension and brass spring-back. The 0.220-inch diameter is typically ideal for precision .20-calibre cartridges like the .204 Ruger, provided your case wall thickness and chamber dimensions match.

Does this heat-treated steel bushing require case neck lubrication during the reloading process?

Yes. Because this is the heat-treated steel version hardened to Rockwell C 60–62, you must apply a proper case neck lubricant prior to sizing to ensure smooth operation and prevent brass galling. If you prefer unlubricated sizing for high-volume reloading, consider the alternative Titanium Nitride coated version.

Neck Sizing Bushing - Redding 73220

The Redding .220 Heat-Treated Steel Neck Sizing Bushing (Model 73220) is a precision reloading component engineered to control cartridge case neck tension without overworking or over-sizing brass. Manufactured with a 0.220-inch inner diameter, this bushing allows handloaders to precisely set neck dimensions to optimize bullet grip and extend brass case life. The internal surface is hand-polished to minimize sizing effort and reduce friction on cartridge necks during reloading.

Key Features

Precision Neck Tension Control: Sizes the case neck to a specific 0.220-inch inner diameter, eliminating excessive brass working compared to standard non-bushing dies.
Hand-Polished Interior: Features a hand-polished internal bore to lower sizing resistance and minimize the risk of brass galling.
Heat-Treated Durability: Hardened to Rockwell C 60–62 (Rc 60–62) for dimensional stability and extended operational wear resistance under repeated sizing cycles.
Interchangeable Interface: Built to standard external dimensions of 1/2-inch outer diameter by 3/8-inch length, enabling use across compatible bushing die systems.
Clear Size Stamping: Marked directly with the 0.220-inch measurement for quick identification on the reloading bench.

Who is the Redding .220 Heat-Treated Steel Neck Sizing Bushing for?

Precision handloaders tuning .20-calibre cartridges — requires a 0.220-inch inner diameter steel neck sizing bushing to establish correct neck tension on small-bore brass such as .204 Ruger.
Benchrest shooters utilizing Redding or Wilson-style bushing dies — utilizes the standardized 1/2-inch outer diameter by 3/8-inch length profile and Rockwell C 60–62 hardened steel construction to maintain exact case neck dimensions across competitive shooting strings.

Less suitable for: Sizing operations requiring neck diameter reductions greater than 0.004" to 0.005" in a single pass; severe reductions distort case necks and require stepped downsizing using intermediate-diameter bushings, while unlubricated or high-volume workflows are better served by a Titanium Nitride (TiN) coated bushing.
