HRN EXP. SPINDLE ASSY for RCBS DIE (30cal)

Make your RCBS size die easier and more convenient to use. Designed to fit RCBS Elliptical Dies. 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 our New Dimension Dies, which reduces neck stretching and leaves inside of neck extra smooth.
