The Hornady Custom Grade New Dimension Full Length Sizer Die is a great die for the avid reloader. The Full Length Sizer die features polished elliptical expanders that significantly reduce case neck stretch. The hardened steel decapping pin will not bend or break even when depriming cases with a crimped primer pocket. The Full Length Sizer Die also features a Zip Spindle with a series of light threads cut on the spindle and spindle collet. This eliminates spindle slippage and makes tightening the spindle lock a breeze when making adjustments. Shellholder sold separately.
