RCBS Neck Sizing Die Bushing, 0.312 in.

This 0.312-inch bushing (RCBS part no. 81627) is a single interchangeable insert for RCBS‘s bushing-style neck sizing dies. Bushing dies work by swapping in a bushing sized to the exact neck diameter you want, rather than sizing every case down to one fixed dimension, so handloaders buy bushings individually to build out a set covering the brass and neck tension they actually load. This listing is the 0.312-inch bushing only.

Key Specifications

• Precision inside diameter of 0.312 inch, the defining spec for this bushing.
• Sold as a single bushing, meant to be used inside an RCBS bushing-style neck sizing die body.
• Lets handloaders stock multiple diameters for different brass or neck-tension needs without buying a whole new die.
