Hornady Zip Spindle Kit Multi-Caliber Sizer Die Conversion

The Hornady Zip Spindle Kit is a reloading accessory designed to convert any Hornady New Dimension sizing die to Hornady's modern threaded spindle design. The Zip Spindle uses light threads cut on both the spindle and collet, providing a secure, self-centering grip that holds cases firmly during resizing and decapping.

This multi-caliber conversion kit is compatible with any Hornady New Dimension sizer die except 17 and 20 caliber, covering 22 caliber and larger reloading dies. Note that the kit does not include a decapping pin retainer or expander — it is a die-conversion upgrade only, intended for reloaders who want to modernize their existing New Dimension die setup without purchasing an entirely new die.

The kit consists of a new threaded spindle (decapping rod) and a threaded spindle collet in a silver finish, ready to drop into your existing Hornady New Dimension sizing die.
