Redding 73 Style Steel Bushing/.331

The Redding 73 Style Steel Bushing/.331 is a precision neck-sizing bushing built for reloaders who demand consistency and durability in their reloading setup. If you're running a Redding Type S or similar bushing-style neck-sizing die, this .331" bushing gives you the ability to fine-tune neck fit on fired brass without full-length resizing. Heat-treated steel construction with a surface hardness of Rc 60–62 means the sizing diameter resists wear even after thousands of rounds, keeping your neck tension predictable and your loads repeatable.

Redding offers these bushings in .001" incremental sizes, so whether you're working with magnum rifle cartridges, wildcats, or any intermediate bore diameter, you can dial in the exact neck diameter your reloading process requires. Hand-polished sizing surfaces reduce the effort needed to push brass through, which translates to less wear on your press and smoother, more consistent sizing strokes. This is the kind of attention to detail that separates serious reloading equipment from generic alternatives.

The .331" bushing is ideal for cartridges that need a neck size just under standard diameter—common in precision rifle reloading where you want to preserve case life and maintain tight bullet-to-neck fit without the stress of full-length resizing. Drop it into your Redding Type S or compatible die body, and you're ready to size. Redding bushings are also interchangeable with similar bushing-style dies from other manufacturers, making this a versatile addition to any reloading bench.

Frequently Asked Questions

What's the .331" size used for?

The .331" bushing works with cartridges requiring a neck size slightly under standard diameter. It's commonly used in precision rifle reloading to maintain consistent neck tension while preserving case life through neck-only sizing.

Will this bushing fit my reloading die?

The Redding 73 Style Steel Bushing is compatible with Redding Type S neck-sizing dies and similar bushing-style die bodies from other manufacturers. Confirm your die accepts 73-style bushings before ordering.

How do I know if .331" is the right size for my brass?

The correct bushing size depends on your fired case neck diameter and your target neck tension. Start by measuring your sized brass with a caliper or micrometer, then order a bushing that produces your target dimension. Redding offers sizes in .001" increments to dial in the perfect fit.

How long will this bushing last?

The hardened steel construction and hand-polished surface are designed to withstand thousands of sizing cycles. With normal use and care, a Redding bushing will outlast multiple batches of brass.
