Hornady Carbide Expander Spindle Assembly RCBS Dies 219 Zipper, 220 Swift

Make your RCBS rifle sizer die easier and more convenient to use. The carbide expander ball provides chatter-free neck expansion, while reducing the need for inside neck lubrication. Also includes hardened steel elliptical expander, the same found on Hornady New Dimension™ Dies, which reduces neck stretching and leaves the inside of neck extra smooth.

Designed to fit RCBS standard rifle sizer dies only.
