RCBS .341" Steel Neck Sizing Bushing

Steel neck sizing bushing from RCBS, .341 inch. Bushing neck dies size the neck with an interchangeable ring rather than with a fixed dimension cut into the die, and this is one of those rings.

The advantage shows up in brass life and in consistency. Sizing a neck down only as far as it needs to go works the brass less than a full squeeze and expand cycle, and it lets a loader hold neck tension steady as necks thicken over repeated firings. Sizes step in thousandths so there is room to chase that. Steel construction. Verify the bushing style your die takes before ordering.
