Redding 73 Style Steel Bushing/.257

A Redding 73 Style Steel Bushing in .257" diameter is the precision neck-sizing tool serious handloaders reach for when they want consistent, controlled case sizing without the hassle of full-length resizing. This hardened steel bushing is designed to work with Redding's 73 style die systems, letting you fine-tune neck tension on your rifle brass for tighter groups and easier chambering.

Redding's 73 style bushings are hand-polished to keep friction low during the sizing stroke—a detail that matters when you're working with tough brass or running high volume at the reloading bench. The .257" bushing is one size in a comprehensive lineup spanning .185" through .368" in single-thousandth increments, so whether you're loading for a .25-06, .257 Weatherby, or another cartridge in that bore diameter, you can dial in the exact neck clearance your rifle demands. Heat treatment to Rc 60–62 hardness ensures the bushing won't wear quickly under repeated sizing cycles.

If you're building a precision handloading setup or upgrading an existing Redding die system, this bushing gives you the control and repeatability that separates good ammunition from ammunition that shoots. It's a straightforward, durable tool—no bells, no firmware updates, just steel that's been hardened and polished to do one job well.

Frequently Asked Questions

What Redding die systems does this .257" bushing fit?

This bushing is designed for Redding 73 style die systems. It will work with any 73 style Redding reloading die that accepts interchangeable bushings.

What cartridges use a .257" neck bushing?

The .257" bushing is suitable for mid-range rifle cartridges with a .257" bore diameter. Specific cartridge compatibility depends on your particular brass and desired neck tension; consult your reloading manual and die instructions to confirm the right bushing size for your application.

How does a bushing help with reloading?

A neck-sizing bushing allows you to size only the case neck while leaving the body untouched, reducing resizing effort and improving case longevity. The hardened, polished surface minimizes friction and provides consistent sizing cycle after cycle.

Will this bushing wear out?

Redding's heat-treated steel bushings (Rc 60–62 hardness) are built to handle thousands of sizing cycles. You may eventually need to replace it depending on how much brass you process, but proper bushing maintenance and occasional cleaning will extend its service life significantly.
