RC BUSHING DIAMETER - 0.337

The RC Bushing Diameter - 0.337 is a precision reloading component designed for shooters and handloaders who require consistency and reliability in ammunition assembly. This RCBS bushing is essential for fine-tuning neck tension and bullet seating depth, allowing reloaders to achieve the precision that factory ammunition often lacks.

Manufactured to RCBS's high standards, the 0.337-inch bushing diameter works within the full-length sizing die system to control case neck dimensions during resizing. Its tight tolerances ensure consistent bullet grip and minimal runout, which directly contributes to improved velocity stability and group consistency downrange. Made from hardened steel, this bushing is built to withstand repeated reloading cycles without wear.

Ideal for reloaders working with mid-size cartridges, this bushing is a significant upgrade from standard full-length sizing dies, providing superior neck control. Installation is straightforward within any RCBS bushing-style sizing die system, making it a valuable addition for precision reloaders and competitive shooters alike.
