Redding 73 Style Steel Bushing/.288

The Redding 73 Style Steel Bushing in .288" diameter is a precision neck-sizing component built for handloaders who want consistent, controlled case preparation. These heat-treated steel bushings are the working heart of Redding's 73 neck-sizing die system—they grip and resize your fired brass to exact specifications with minimal runout, a critical step for accurate ammunition and repeatable long-range performance.

Each bushing is hand-polished to a surface hardness of Rc 60-62, which reduces the effort needed to push cases through during sizing while maintaining durability through hundreds of reload cycles. The .288" diameter is one of dozens available in .001" increments, so you can dial in the precise neck tension your load demands. Whether you're chasing tight groups at the range or building ammo for elk and mule deer, starting with the right bushing size gets you halfway there.

These bushings are a no-frills, proven component—no marketing, just hard steel that's been trusted by competitive shooters and hunters for decades. If you're already running a 73-style die, swapping to a different bushing size takes seconds and costs far less than replacing the entire die, making them the smart choice when you need to adjust neck tension for different powders, primers, or barrel combinations.

Frequently Asked Questions

Will this bushing work with my Redding 73-style die?

Yes. The .288" bushing is designed specifically for Redding 73 neck-sizing die systems and drops in without modification.

What does the .288" size mean?

The .288" diameter is the inside dimension of the bushing that actually contacts and sizes your case neck. Redding offers sizes in .001" increments from .185" to .368", so you can choose the diameter that gives you the neck tension your cartridge and load require.

Can I use different bushings to adjust neck tension without buying a new die?

Yes. Swapping bushings is one of the key advantages of the 73-style system. By changing to a slightly larger or smaller bushing, you can fine-tune neck tension for different powders, primers, or barrel characteristics—all without replacing the entire die.

How long will these bushings last?

The hand-polished, heat-treated steel construction and Rc 60-62 hardness are designed for hundreds of reload cycles. Wear and lifespan depend on case hardness, lubrication, and how much you resize, but these bushings are built to outlast most reloaders' patience.
