RC BUSHING DIAMETER - 0.363

The RCBS RC Bushing Diameter 0.363 (SKU RC81678, MPN 81678) is a precision reloading bushing designed for rifle ammunition preparation. This component is engineered for shooters and reloaders who demand accuracy and repeatability in their cartridge sizing operations. The 0.363-inch diameter specification makes this bushing suitable for standard rifle caliber neck sizing, a critical step in the reloading process that directly impacts chamber fit and firing accuracy.

RCBS bushings are precision-engineered components manufactured to tight tolerances to ensure consistent neck diameter control during the sizing stage. The 0.363-inch bore diameter is a common specification used in rifle reloading for various calibers where precise neck sizing is essential. Reloaders select specific bushing diameters based on their target case neck dimensions and desired fit specifications. This bushing integrates with RCBS sizing dies and accessory systems, allowing shooters to fine-tune their reloading setup for optimal consistency and performance across multiple loading cycles.

This component is essential for precision rifle reloaders, competition shooters, and hunters who reload their own ammunition. Proper neck sizing with the correct bushing diameter minimizes case neck runout, reduces bullet seating variance, and helps achieve tighter shot groups downrange. Whether preparing match-grade ammunition for benchrest competition or crafting hunting loads for accuracy-critical applications, the ability to select the exact bushing diameter needed is fundamental to reloading success. The compact 1.5 × 0.07 × 6-inch dimensions allow this bushing to be stored and organized with other reloading components and dies.
