Redding 73 Style Steel Bushing/.307
The Redding 73 Style Steel Bushing/.307 is a precision neck-sizing bushing engineered for handloaders who demand consistency and repeatability in their reloading process. This .307" bushing is part of Redding's extensive lineup of heat-treated steel bushings, designed to work with 73-style reloading dies for controlled case neck sizing. Whether you're fine-tuning loads for accuracy at the range or preparing ammunition for hunting, a properly matched bushing is essential to achieving the tight concentricity and neck tension that separates good handloads from great ones.
Each bushing is manufactured from heat-treated steel and hand-polished to exacting tolerances, with a surface hardness of Rc 60-62 that reduces sizing effort during the reloading cycle. The polished sizing diameter ensures smooth operation and minimal wear on your cases over hundreds of reloads. Redding produces these bushings in .001" increments across a full range of diameters, so you can dial in the exact neck size your specific cartridge and die setup requires.
The .307" bushing works best when paired with a 73-style die body—make certain your reloading press setup includes a compatible Redding 73-style neck-sizing die before ordering. This is a wear item that will eventually need replacement as it polishes further with use, so having spares on hand is smart planning for dedicated reloaders.

Frequently Asked Questions
Will this bushing work with my Redding reloading die?
This bushing is designed for 73-style Redding die bodies. If your reloading setup uses a 73-style neck-sizing die, this bushing will be compatible. Check your die documentation or contact the manufacturer if you're unsure which style you own.
What does the .307" size mean?
The .307" refers to the nominal diameter of the polished sizing hole in the bushing. This size is one of many available in .001" increments across Redding's range, allowing you to match your specific cartridge neck specifications.
How often do I need to replace my bushing?
Bushings are wear items that will gradually polish further with use over time. The hand-polished surface allows for hundreds of reloads before noticeable wear occurs, but eventual replacement is normal as part of reloading equipment maintenance.
What's included with this bushing?
You receive the single .307" bushing only. A compatible 73-style die body is required to use this bushing in your reloading setup.
