RC BUSHING DIAMETER - 0.290

The RCBS RC Bushing Diameter 0.290 (SKU RC81605) is a precision reloading component designed for handloaders who demand exacting control over case neck sizing. This bushing is a core element of the RCBS bushing-style sizing die system, which allows reloaders to select the exact bushing diameter needed for their specific caliber and brass dimensions.

The 0.290-inch diameter accommodates popular rifle cartridges and delivers the consistent, controlled neck sizing that serious precision shooters rely on for repeatable ammunition. Bushing-style sizing dies offer a critical advantage over conventional full-length dies: they allow neck tension to be fine-tuned without affecting shoulder dimensions or overall case fit.

This bushing is essential for reloaders using RCBS bushing-style dies who need to achieve tight neck tolerances and optimize bullet seating consistency. Whether you're developing handloads for a precision rifle, managing neck tension for match ammunition, or refining loads for hunting, selecting the correct bushing diameter directly impacts both accuracy and case life.
