The Redding 73 Style Steel Bushing in .312" diameter is a precision neck-sizing component for reloaders who want tight, consistent case neck fit without full-length sizing. This hardened steel bushing works with Redding's 73 Style die system to size rifle cartridge necks to your exact specifications. If you're building match-grade ammunition or working with premium brass, a properly sized neck bushing is one of the most effective ways to improve concentricity and shot-to-shot consistency.
Redding's bushings are hand-polished and heat-treated to a surface hardness of Rc 60–62, which means they're durable enough to handle hundreds of reloading cycles without developing the wear that softens inferior alternatives. That hardness also reduces the effort needed during sizing, which matters when you're processing cases in volume or have a progressive press that demands smooth, predictable resistance. The .312" size positions this bushing for common rifle cartridges in that neck diameter range.
Redding offers bushings throughout the range of .185" to .368" in .001" increments, so you can dial in your exact neck diameter. The three-digit suffix in the part number (RD73XXX) identifies the bushing size, making it easy to cross-reference and stock multiple sizes for different cartridges. Reloaders who prioritize accuracy and consistency return to Redding bushings because they're a proven, no-nonsense way to control case prep quality without complexity.

Frequently Asked Questions
What cartridges use a .312" neck bushing?
The .312" bushing is sized for rifle cartridges with that neck diameter. Check your cartridge specifications to confirm the correct bushing size for your load. Redding bushings are available in .001" increments from .185" to .368" to cover the full range of common rifle rounds.
Is this bushing compatible with all Redding dies?
This is a 73 Style bushing, designed for use with Redding's 73 Style die system. Confirm your die model and neck size before ordering to ensure compatibility.
Why are hardened bushings better for reloading?
The Rc 60–62 surface hardness resists wear from repeated sizing cycles and reduces the friction and effort required during the sizing stroke. This consistency translates to more uniform neck tension across your ammunition.
