Redding 73 Style Steel Bushing/.310

The Redding 73 Style Steel Bushing in .310" diameter is a precision neck-sizing component for reloaders who demand consistent, repeatable ammunition. This hardened steel bushing fits Redding's 73 die system and handles the critical task of controlling case neck tension during the sizing process—a key step in producing accurate, reliable rounds for match shooting, hunting, or precision rifle work.

Built from heat-treated steel with a polished sizing diameter, this bushing carries a surface hardness of Rc 60-62, engineered to reduce the effort required to size cases while maintaining the dimensional accuracy your loads depend on. The .310" size is one of dozens available in .001" increments across Redding's bushing lineup, allowing you to dial in the exact neck tension your cartridge and bullet combination needs. Whether you're working with a popular caliber or a wildcat, Redding's granular sizing options let you fine-tune your reloading to match your rifle's requirements.

If you're already running a Redding 73 die setup, swapping bushings is straightforward—no special tools or die modifications required. It's the kind of straightforward upgrade that serious reloaders reach for when they want to optimize their ammunition production without overhauling their whole press setup.
