Redding 73 Style Steel Bushing/.287

The Redding 73 Style Steel Bushing in .287" diameter is a precision neck-sizing component for reloaders who demand consistency and minimal sizing effort. This heat-treated steel bushing fits Redding's 73 Style die system and is hand-polished to a surface hardness of Rc 60–62, making it one of the most durable and efficient bushing options available for serious ammunition crafting. If you're loading for a cartridge that calls for a .287" neck size, this bushing delivers the exact diameter you need in increments matched across Redding's full range.

Neck-sizing bushings are essential when you want to control case neck dimensions independently of body sizing—a technique that extends case life and improves shot-to-shot consistency, especially valuable for match ammunition and precision hunting loads. The hand-polished surface reduces the effort required during the sizing stroke, which adds up when you're processing hundreds of rounds. Redding's 73 Style system lets you swap bushings easily, so you can quickly adjust sizing diameter if you change cartridges or alter your loading specifications.

This is a .287" bushing only; if your load requires a different neck diameter, Redding offers bushings in .001" increments from .185" through .368", so you'll find the exact size your recipe demands. Whether you're fine-tuning loads for a custom rifle or standardizing neck diameter across a new batch of brass, a properly sized bushing is the foundation of repeatable, accurate ammunition.

Frequently Asked Questions

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

A neck-sizing bushing lets you resize only the neck of a rifle case, leaving the body dimensions alone. This extends case life, improves accuracy by reducing runout variation, and is especially useful for handloading precision ammunition. If you want tighter control over case neck dimensions, a bushing die system is the way to go.

Will this .287" bushing fit my Redding die?

This bushing is designed for Redding 73 Style die systems. If you're using a different Redding die system or a die from another manufacturer, you'll need to verify compatibility—contact the die manufacturer or Redding directly if you're unsure.

What if I need a different bushing size?

Redding offers 73 Style bushings in .001" increments from .185" through .368" diameter. The part number format is RD73XXX, where the last three digits denote the size. You can order bushings individually and swap them as your loads or cartridges change.

What cartridges use a .287" neck?

The .287" diameter is the appropriate neck size for specific cartridge specifications. Consult your load data or cartridge reference to confirm the correct neck size for your ammunition.
