Redding 73 Style Steel Bushing/.306

The Redding 73 Style Steel Bushing/.306 is a precision neck-sizing component built for handloaders who demand consistent, repeatable ammunition. This .306-inch bushing fits Redding's 73 Style press system and gives you the exact neck diameter control that competitive shooters, precision hunters, and reload enthusiasts rely on for tight velocity spreads and sub-MOA groups. Made from heat-treated steel with a hardened sizing diameter, it reduces the effort required to size brass while maintaining the durability needed for thousands of rounds.

Redding bushings are engineered to a high standard—the sizing diameters are hand-polished and surface-hardened to Rc 60–62, which means they wear slowly and deliver consistent sizing pressure over extended use. The .306-inch size sits in the middle of Redding's lineup and accommodates the most common medium-bore cartridge families. If you're loading .300 Win Mag, .308 Winchester, or similar calibers, this bushing gives you the precision neck control that separates good ammo from match-grade ammo.

Redding's 73 Style bushings are available in .001-inch increments across their full range, so if your brass neck diameter measures slightly tighter or looser than standard, you can dial in the perfect fit. This modular approach means you invest in one press system and build a library of bushings as your cartridge collection grows.

Frequently Asked Questions

What press system does this bushing fit?

The Redding 73 Style Steel Bushing is designed for Redding's 73 Style reloading press. Verify your press model before ordering.

What calibers use a .306-inch bushing?

The .306-inch size accommodates medium-bore cartridges such as .300 Win Mag, .308 Winchester, and similar rounds that require that neck diameter. Check your brass neck measurements to confirm the right fit for your load.

How long does a Redding bushing last?

Redding bushings are engineered for extended use. The hand-polished, hardened steel sizing diameter resists wear over thousands of reloading cycles, though bushing life depends on brass hardness, press technique, and frequency of use.

Can I get a different bushing size if .306 isn't quite right?

Yes. Redding manufactures 73 Style bushings in .001-inch increments across their full range (.185 inch through .368 inch), so you can find or order the exact diameter your brass requires.
