Description
This is the .228 diameter steel bushing from Redding's 73-style lineup, the part that turns a bushing-style die into a tool you can fine-tune to your exact brass. Instead of overworking your necks the way a standard die can, you pick the bushing that matches your loaded neck diameter and get just the grip on the bullet you're after. It's a small piece that makes a real difference once you start chasing consistency.
What the Redding .228 Steel Bushing Does for You
The internal diameter here is .228 inches, and the whole bushing is machined to Redding's usual standard with hand-polished sizing diameters and a surface hardness around RC 60-62. That hardness is there to cut down on sizing effort and keep the bushing wearing evenly over a long life. Because it's a heat-treated steel bushing, it's the straightforward, no-frills option compared to the titanium nitride versions, and plenty of reloaders stick with steel for that reason.
Picking the Right 73 Style Bushing Size
Getting the size right is simple. Measure the outside diameter of a loaded cartridge neck with a bullet seated, then subtract about .001 inch from your smallest measurement. That's your starting bushing. Bushings come in .001 inch increments, so you can get as precise as your load work calls for, and if you shoot moly-coated bullets you may want to drop down another .001 or .002 for a little more tension.
Fit and Compatibility
This bushing uses the standard 1/2 inch outside diameter by 3/8 inch long profile, so it drops into Redding Type S and Competition bushing-style sizing dies and interchanges freely between them. It also works with Wilson-style bushings of the same dimensions. If you're loading a .20 caliber cartridge or anything where a .228 neck sizing bushing fits your brass, this is a reliable piece to keep in the box. Most folks end up with a few sizes on hand to tune different lots of brass, and a dedicated bushing box is handy for keeping them organized.

Frequently Asked Questions
How do I know if the .228 Redding bushing is the right size for my brass?
Measure the outside diameter of a loaded cartridge neck with a bullet seated, then subtract about .001 inch from your smallest reading. If that comes out to roughly .228 inches, this bushing is your match. If you load moly-coated bullets, you may want to size down an extra .001 or .002 for added neck tension.
Which dies does this Redding 73 style steel bushing fit?
It drops into Redding Type S and Competition bushing-style sizing dies and interchanges freely between them. The bushing uses the standard 1/2 inch outside diameter by 3/8 inch long profile, so it also works with Wilson-style bushings of the same dimensions.
What's the difference between the steel bushing and the titanium nitride version?
Both share the same dimensions and hand-polished sizing diameters, so either one will size your necks accurately. The titanium nitride coating adds extra lubricity and can reduce stress on the brass during sizing, while this heat-treated steel version is the simpler, proven option that many reloaders prefer. Performance-wise, both do the job well.
Why use a bushing instead of a standard neck sizing die?
A bushing lets you control exactly how much you resize the neck, so you set the right amount of bullet grip without overworking the brass. That means longer case life and more consistent neck tension, which usually translates to better accuracy. You just swap bushings in .001 inch increments to tune for different brass lots.
