Redding 73 Style Steel Bushing/.337

The Redding 73 Style Steel Bushing in .337" diameter is a precision neck-sizing component built for reloaders who demand consistent, accurate ammunition. Whether you're fine-tuning loads for a match rifle, hunting rifle, or custom chambering, this hardened steel bushing lets you dial in exactly the neck tension you need without oversizing cases or wasting components.

Redding's 73 style bushings are hand-polished to a surface hardness of Rc 60–62, which reduces the effort required during the sizing stroke while maintaining the precision tolerances that separate good loads from great ones. The .337" diameter puts this bushing in range for popular cartridges and custom builds in that bore class. Like all Redding bushings, it's manufactured in increments of .001", so you can dial in the exact neck diameter your loads demand.

If you're already running a Redding 73 die body or similar bushing-style press setup, swapping in a different bushing diameter takes seconds and requires no die adjustment—a huge advantage when you're experimenting with neck tension or moving between similar cartridges. Stock the diameters you actually shoot, and you'll save time and brass.

Frequently Asked Questions

What Redding reloading dies work with this bushing?

This bushing is compatible with Redding 73 style neck-sizing die bodies. If you own or plan to use a Redding 73 die, this bushing will fit.

Why choose a bushing-style die over a standard die?

Bushing-style dies let you adjust neck tension by swapping bushings without changing the die itself. If you load multiple cartridges with similar body diameters or want to experiment with different neck fits, bushings save time and give you repeatability across different ammunition batches.

Do I need different bushings for different cartridges?

If two cartridges share the same neck diameter, one bushing will work for both. The .337" bushing is sized to cartridges in that specific bore class. Check your cartridge specs to confirm neck diameter before ordering.

What does hand-polished sizing diameter mean?

The interior surface where cases make contact is hand-polished to a precise diameter and hardened to Rc 60–62. This reduces friction during sizing, lowers the effort required at the press, and helps ensure consistent neck tension with minimal variation between strokes.
