The Hornady Custom Grade New Dimension Nitride 3-Die Set is a great die set for the avid reloader. The set includes a CGND Nitride Full-length Sizing Die, CGND Adjustable Case Mouth Expander Die, and CGND Seater Die with roll crimp. The Sizer Die features Titanium Nitride sizing rings that eliminate case sticking and require no case lubrication. The Sizer Die also features the Zip Spindle, with a series of light threads cut on the spindle and spindle collet. This is designed to eliminate spindle slippage and makes tightening the spindle lock a breeze when making adjustments. The CGND Seating Die features seater adjustment screw, built-in crimper, locking retainer spring, and a floating bullet seater alignment sleeve and seating stem, which pre-aligns the bullet and case before seating occurs. The die set comes packaged with a plastic storage box and includes three Sure-Loc Rings. Shell holder sold separately.
