Redding 73 Style Steel Bushing/.336

The Redding 73 Style Steel Bushing/.336 is a precision neck-sizing component built for handloaders who demand consistency and control over their brass preparation. This .336" bushing fits into Redding's 73 style die system, giving you the ability to fine-tune neck diameter independently of your full-length sizing operation—a critical step for shooters pursuing tighter groups and more uniform loading across a batch of ammunition.

Hand-polished sizing surfaces with a hardness rating of Rc 60–62 keep friction low during the bushing stroke, reducing the effort required to size your necks while protecting case shoulders from unnecessary work hardening. The steel construction and precision tolerances make this bushing a durable, repeatable solution whether you're sorting brass for a hunting rifle, precision range load, or match-grade ammunition.

Redding offers neck-sizing bushings across a comprehensive range of diameters in .001" increments, so you can dial in the exact neck fit your cartridge and bullets demand. The .336" bushing suits specific applications and calibers; verify your target neck diameter before ordering to ensure the right fit for your reloading setup.

Key Features

Frequently Asked Questions

What is a neck-sizing bushing and why would I need one?

A neck-sizing bushing allows you to resize only the neck of a cartridge case without full-length sizing. This is valuable for precision handloading because it minimizes case working, improves brass longevity, and can improve accuracy by maintaining consistent neck tension on your bullets. It's especially useful for match-grade loads and when shooting in a single firearm.

Will this bushing fit my Redding die set?

This bushing is designed for Redding 73 style dies. Verify that your die system accepts 73 style bushings. Redding offers bushings in sizes from .185" through .368", so you can select the diameter that matches your target neck size. The .336" bushing is intended for specific cartridge applications—confirm your required bushing diameter before ordering.

What does the hand-polished surface do?

The hand-polished sizing diameter, hardened to Rc 60–62, reduces friction between the case neck and bushing during the sizing stroke. This decreases the effort required to size your cases and helps preserve case shoulder integrity by minimizing unnecessary working of the brass.
