RC BUSHING DIAMETER - 0.303

The RCBS RC Bushing Diameter 0.303 (part number 81618) is a precision sizing bushing designed for reloaders who require consistent case neck concentricity and uniform bullet seating. This 0.303-inch bushing is an essential part of the RCBS bushing system, utilized within full-length die assemblies to manage case neck diameter during the sizing process.

Engineered for cartridges that demand tight neck tolerances, this bushing provides the dimensional accuracy necessary for producing match-grade ammunition. It threads into compatible RCBS die bodies, allowing for easy swapping to match various cartridge specifications or to fine-tune neck tension based on specific bullet weights and powders.

This component is particularly beneficial for precision rifle reloaders, benchrest competitors, and anyone loading ammunition where repeatability and uniformity are crucial for performance. Whether developing loads for long-range hunting or precision shooting, selecting the correct bushing diameter is vital for achieving optimal results.
