Redding 73 Style Steel Bushing/.313

The Redding 73 Style Steel Bushing in .313" diameter is a precision neck-sizing component for handloaders who want consistency and repeatability in their ammunition. These bushings are the foundation of a proper neck-sizing setup—they work with Redding's 73 series reloading dies to control case neck diameter during the resizing stroke. Whether you're loading match-grade rifle cartridges, hunting rounds, or precision pistol ammo, choosing the right bushing diameter is critical to achieving tight, uniform neck tension across your lot.

Redding's steel bushings are heat-treated to Rc 60-62 surface hardness, which means they'll stand up to the mild abrasion of repeated sizing cycles without wearing out quickly. The sizing surfaces are hand-polished to smooth out any tool marks, reducing the force needed to push cases through and lowering the wear on your press and dies. That polish also means cleaner, more consistent sizing—no chattering or binding that would throw off neck tension.

The .313" bore is just one option in Redding's full range; bushings come in .001" increments from .185" through .368", so you can fine-tune your neck diameter to match your brass, bullets, and pressure requirements. If you're already set up with a 73 series die, swapping bushings takes seconds and costs far less than buying a whole new die set. It's the reloader's path to better accuracy without breaking the bank.

Frequently Asked Questions

What reloading dies does this bushing fit?

This bushing is designed for use with Redding 73 series neck-sizing dies. Confirm your die model before ordering to ensure compatibility.

What calibers would use a .313" bushing?

The .313" diameter is a common neck size for several cartridges, but the best bushing size depends on your specific brass, bullet diameter, and desired neck tension. If you're unsure which size you need, consult your die instructions or contact Redding directly.

Can I swap bushings between different dies?

Bushings are interchangeable within the Redding 73 series line. Swapping to a different bushing diameter is a quick way to adjust neck tension without replacing the entire die.

What makes hand-polished bushings better than standard ones?

The hand-polished sizing surface is smoother, which reduces friction and sizing effort. This gentler process also helps maintain more uniform neck tension across your brass and extends the life of both the bushing and your press.
