Redding 73 Style Steel Bushing/.304

The Redding 73 Style Steel Bushing in .304" is a precision neck-sizing component built for reloaders who demand consistency and minimal sizing pressure. This hardened steel bushing fits the popular 73 style neck-sizing system and is engineered to handle the work without pushing your press to its limits. Whether you're fine-tuning loads for match shooting or prepping brass for hunting ammo, a properly matched bushing is the foundation of repeatable, accurate reloads.

Redding manufactures these bushings from heat-treated steel and hand-polishes the sizing surface to a hardness of Rc 60–62. That hardness matters: it reduces the force needed to size your brass, extends the bushing's service life, and helps maintain dimensional consistency across hundreds of rounds. The .304" size fits a wide range of cartridges and is available as part of Redding's comprehensive bushing lineup, which spans .185" through .368" in .001" increments, so you can dial in your neck clearance with surgical precision.

If you're already running a Redding 73 style neck-sizing die setup, the bushing swap takes seconds. Drop it in, resize your brass, and move to the next station. No guesswork, no hunting for the right component—Redding's numbering system makes it simple: the last three digits of the part number tell you exactly what you're getting.

Frequently Asked Questions

Will this bushing work with my Redding neck-sizing die?

Yes, if you have a Redding 73 style neck-sizing die. The .304" bushing is designed to drop into that die system. If you're unsure which die you own, check your die box or the Redding part number on the die itself.

What makes this bushing different from cheaper alternatives?

Redding's bushings are heat-treated and hand-polished to Rc 60–62 hardness. That hardness reduces the force needed to size your brass and helps the bushing maintain its dimensions through hundreds of reloading cycles. A quality bushing pays for itself in consistency and longevity.

How do I know what bushing size I need?

Bushing size is determined by the outside diameter of your case neck. Redding offers bushings in .001" increments from .185" through .368", so you can dial in your neck clearance precisely. Most reloaders select a bushing that sizes the neck to fit the bullet snugly without excessive force.

Is this bushing available in other sizes?

Yes. Redding manufactures 73 style bushings throughout a wide range: .185" to .250", .251" to .305", and .306" to .368". All are made to the same heat-treated, hand-polished standard.
