RC BUSHING DIAMETER - 0.333

The RCBS RC Bushing Diameter 0.333 (SKU: RC81648, MPN: 81648) is a precision reloading bushing designed for ammunition handloaders who demand consistent case neck sizing. This component is essential for reloaders seeking to maintain tight tolerances and repeatable cartridge specifications across multiple loading cycles.

The 0.333-inch diameter specification suits specific cartridge neck sizes and is part of RCBS's modular bushing system, allowing reloaders to customize their sizing dies to their exact requirements. By using the correct bushing diameter for your cartridge, you control the amount of neck squeeze applied during the sizing stroke—critical for controlling bullet grip, runout, and chamber fit.

This bushing integrates seamlessly into RCBS sizing die bodies, making it a drop-in replacement for worn or damaged units. Handloaders working with rifle cartridges or precision pistol loads rely on bushing selection to fine-tune neck tension. Whether you're developing match-grade ammunition for competition, hunting, or precision rifle work, maintaining proper sizing control through the right bushing diameter ensures batch-to-batch consistency.
