The Redding Type S - Bushing Style Neck Sizing Die provides reloaders with a simple means to precisely control case neck size and tension.  The die uses interchangeable sizing bushings available in .001" increments (sold separately).  The adjustable decapping rod allows positioning the bushing to resize only a portion of the neck length if desired.  Concentricity is enhanced by the ability of the resizing bushing to selfcenter on the case neck.  The decapping rod is supplied with a standard size button. This is especially useful for reloaders who are using commercial brass as is.  A decapping pin retainer is also supplied with most Type S - Bushing Dies except 17 and 20 Cal. This enables neck sizing without the use of the size button for those who sort and/or turn case necks for uniformity.
