Redding 73 Style Steel Bushing/.301

The Redding 73 Style Steel Bushing/.301 is a precision neck-sizing component for reloaders who demand consistency and durability in their ammunition production. This .301" bushing is part of Redding's extensive lineup of interchangeable neck-sizing bushings, engineered to integrate with 73 style reloading dies for controlled, repeatable neck sizing on your handloads.

Built from heat-treated steel, this bushing features a hand-polished sizing diameter with a surface hardness of Rc 60-62. That hardness specification matters: it reduces the friction and effort required during the sizing stroke, extending the life of your bushing and making your reloading sessions less fatiguing. The polished surface also helps ensure smooth, consistent neck sizing without chatter or drag that can introduce runout or inconsistent neck tension.

Redding produces 73 style bushings in .001" increments across a wide diameter range, so you can dial in the exact neck sizing you need for your specific brass, bullet diameter, and desired tension. The .301" size is marked clearly and is a direct fit for any 73 style neck bushing reloading die. If you're precision reloading for hunting, competition, or long-range shooting, having the right bushing size ensures your cases are sized consistently shot after shot.

Frequently Asked Questions

What 73 style reloading dies does this bushing fit?

The Redding 73 Style Steel Bushing is an interchangeable component designed for any 73 style neck bushing reloading die. Check your die to confirm it accepts 73 style bushings before purchasing.

How do I know which bushing size I need?

Bushing size depends on your specific brass, bullet diameter, and how much neck tension you want. Redding produces bushings in .001" increments from .185" through .368", so you can fine-tune your sizing. Consult reloading references or your die manufacturer's guidance for your caliber and intended application.

What does the Rc 60-62 hardness mean for reloading?

The surface hardness specification ensures the bushing resists wear during repeated sizing cycles. Harder steel reduces friction and the physical effort required to size each case, and it helps the bushing maintain its polished surface longer, preserving consistent sizing performance over thousands of reloads.

Is this bushing available in other sizes?

Yes. Redding 73 style steel bushings are manufactured throughout the range of .185" to .368" in .001" increments, so you can order the exact diameter your load requires.
