The Hornady Carbide Expander Spindle Assembly is an excellent accessory for improving the performance or your RCBS sizer die. The assembly replaces the RCBS Elliptical die spindle assembly with a Hornady Carbide Expander Spindle Assembly. The carbide expander ball provides chatter-free neck expansion, and reduces the need for inside neck lubrication. The assembly also includes a hardened steel elliptical expander, similar to the expander in the New Dimension dies.
