This dies sizes only the neck to preserve the perfect fit of fire forming. Only reload cases that have been fired in your gun. Not recommended for autoloaders, slide or lever action guns.

The Hornady Custom Grade New Dimension Neck Sizer Die eliminates the problem of excessive headspace and aligns the bullet perfectly with the bore, resulting in better accuracy and longer case life. The CGND Neck Sizer die features polished elliptical expanders, that significantly reduces case neck stretch. The hardened steel decapping pin will not bend or break, even when depriming cases with a crimped primer pocket. The Neck 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. Neck Sizer die should be used on cased fired in bolt-action rifles only.
