Redding 73 Style Steel Bushing/.309

The Redding 73 Style Steel Bushing/.309 is a precision neck-sizing component built for reloaders who demand consistency and durability in their handloading setup. This .309" bushing works within Redding's 73 Style bushing system, allowing you to fine-tune neck tension on your rifle brass for tighter shot groups and repeatable ballistics. Whether you're preparing match rounds or hunting ammunition, a properly fitted bushing is essential to controlling case neck diameter and ensuring rounds chamber smoothly and perform predictably.

Redding manufactures these bushings from heat-treated steel engineered for the demands of precision reloading. The sizing diameter is hand-polished to a surface hardness of Rc 60-62, which reduces the force needed during the sizing stroke—an advantage when you're processing cases by the hundreds. The hardness also extends bushing life, resisting the wear that comes from repeated contact with brass. This .309" bushing fits into the full Redding 73 Style lineup, which offers diameters in .001" increments across the range of .185" through .368", so you can dial in the exact neck diameter your loads and chambers require.

If you're already running a Redding 73 Style die set, adding the correct bushing—or swapping to a tighter or looser one—is a quick way to optimize neck fit without buying a new die. Reloaders who work up precision loads, shoot tight-tolerance rifle matches, or simply want better control over case prep appreciate the repeatability these bushings deliver. Pair this .309" bushing with your 73 Style seating die or sizing die to take your handloading precision to the next level.

Frequently Asked Questions

Is this bushing compatible with my Redding reloading die set?

This .309" bushing is designed for the Redding 73 Style bushing system. If your die set accepts 73 Style bushings, this bushing will fit. Check your die documentation or contact Redding directly to confirm compatibility with your specific die model.

What does .309" mean, and how do I know if this is the right size for my brass?

The .309" diameter is the nominal bushing size. The actual sizing diameter of your bushing may vary slightly by design. To choose the correct bushing, measure your fired case neck or consult load data and your rifle's chamber specs. Redding offers bushings in .001" increments across .185" to .368" to dial in your exact neck-sizing needs.

Why is the hand-polished finish important?

The hand-polished sizing diameter, combined with the Rc 60-62 surface hardness, reduces the force required when sizing brass and extends the bushing's working life. This means easier reloading sessions and longer-lasting equipment that maintains consistent neck tension over thousands of rounds.

Can I use this bushing with different die brands?

This bushing is engineered for the Redding 73 Style system. Compatibility with other brands' dies is not guaranteed. Always verify that your reloading die set accepts Redding 73 Style bushings before purchasing.
