Redding 73 Style Steel Bushing/.305

The Redding 73 Style Steel Bushing/.305 is a precision neck-sizing component built for reloaders who demand consistent, repeatable cartridge dimensions. This .305" bushing fits Redding's 73-style sizing die systems and uses hand-polished heat-treated steel to guide cases smoothly through the sizing process with minimal resistance. If you're loading rifle ammo and want to dial in neck tension for improved accuracy, a properly sized bushing matched to your case geometry is fundamental—this one handles that job with the durability and precision Redding is known for.

Redding manufactures these bushings with a surface hardness of Rc 60-62, which means the polished sizing surfaces stay smooth and true through hundreds of reloading cycles. The steel construction resists wear better than softer materials, so your sizing dimensions stay consistent from the first case to the last in a batch. The .305" diameter is available as part of Redding's full range of bushing sizes, which run from .185" through .368" in .001" increments—allowing you to match your specific case neck OD and achieve the neck tension your load demands.

Whether you're fine-tuning factory brass for a precision rifle or working up loads in a custom caliber, having the right bushing size makes the difference between guesswork and repeatable results. This is a straightforward, durable component with no fancy coatings or unnecessary complexity—just good steel and thoughtful design.

Frequently Asked Questions

What calibers use a .305" bushing?

The .305" bushing matches cases with approximately .305" outside diameter at the neck. Common applications include various rifle cartridges in that neck dimension range, but the specific caliber depends on your case and desired neck tension. Measure your case neck OD and compare it to the bushing size to ensure proper fit.

How do I know which bushing size I need?

Measure the outside diameter of your fired or sized case neck, then select a bushing that matches or is slightly smaller (typically .001" to .003" smaller) than that measurement to achieve appropriate neck tension. Redding offers bushings in .001" increments across their range to let you dial in the fit you want.

Will this bushing fit my Redding die?

This bushing is designed for Redding 73-style neck-sizing dies. Confirm your die is a 73-style before ordering, as other Redding die designs may use different bushing styles.
