Hornady New Dimension I Two Die Rifle Set for .300 Winchester Short Mag 546369 sets itself apart from other reloading dies with the details. Small improvements like a sliding alignment sleeve, fast disassemble retainer ring, an all-steel seater adjustment screw, and wrench flats for the locking rings add up to one effective set of gunsmith and reloading equipment. Hornady has included their innovative Zip Spindle design in all New Dimension Series I reloading dies, a lightly threaded spindle that eliminates slippage and makes tightening the spindle lock a simple task. A smoothly polished elliptical expander is threaded to eliminate neck stretch and allows you to "neck up" to the next caliber without using a third die. The Hornady New Dimension .308 Winchester Short Mag 2 Die Reloading Kit also features a tough headed steel decap pin that doesn't bend or crack, plus a built-in crimper. Compatible with virtually any press, it's easy to see why the Hornady Winchester .300 Short Mag 2 Die Rifle Set is a favorite set of Hornady reloading dies among hand loaders everywhere.
