RCBS .215" Steel Neck Sizing Bushing

A steel neck sizing bushing from RCBS at .215 inch. Bushings are how a neck sizing die gets set to a specific finished neck diameter: swap the bushing, and the neck comes out where the new bushing says instead of where an expander ball leaves it.

Sizing to a chosen number is the whole point of the design. Handloaders pick a bushing by measuring the neck of a loaded round and working back from there, which is why bushings are sold in close increments rather than by cartridge name. This one is steel. Check the bushing size and style your die takes before ordering.
