The Hornady Custom Grade New Dimension -Die Set is a great die set for the avid reloader. This die set includes a Custom Grade New Dimension (CGND) Full Length Sizer Die and a CGND Seating Die. The Full Length Sizer Die 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. The floating bullet alignment sleeve and stem in the CGND Seating Die improve bullet seating and accuracy by pre-aligning the bullet and case before seating. The seating die also applies a crimp to secure the bullet in the case. The CGND die set comes packaged in a plastic storage box, and includes two Sure-Loc rings.
