The RCBS Neck Sizing Die Bushing at 0.289 inch (RCBS part no. 81604) is a precision bushing sized for RCBS bushing-style neck sizing dies. Swapping to the correct bushing diameter lets a handloader dial in exact neck tension for a specific bullet and brass combination instead of relying on a fixed neck size. A 0.289 inch bushing is sized for cases where that neck diameter matches the reloader’s target tension. It’s an inexpensive way to fine-tune sizing without buying a whole new die.
