Redding 73 Style Steel Bushing/.243

The Redding 73 Style Steel Bushing in .243 is a precision neck-sizing component built for reloaders who demand consistency and reduced sizing effort shot after shot. These heat-treated steel bushings are engineered to work with Redding's 73 Style sizing die system, offering you a straightforward way to fine-tune neck tension and achieve tighter, more repeatable cartridge dimensions. Whether you're handloading for a competition rifle or a hunting round, a quality bushing tailored to your exact bore diameter makes the difference between mediocre and match-grade reloads.

Redding's design philosophy here is all about reducing the work—literally. Each bushing's sizing diameter is hand-polished and heat-treated to a surface hardness of Rc 60–62, which cuts down the force needed to push brass through, preserving your press and your hands over a long loading session. That hardness also means the bushing wears evenly and slowly, so your neck dimensions stay consistent across hundreds of rounds.

The .243 bushing fits into Redding's extensive sizing bushing lineup, which covers .185" through .368" in .001" increments. That granular sizing lets you dial in neck tension precisely—critical if you're working with tight-tolerance brass or chasing single-digit ES spreads. The part number format (RD73XXX) makes it easy to identify the exact size you need; this one is sized specifically for .243-caliber necks.
