Hornady's Custom-Grade Dies provide a lifetime of reloading. They're so well crafted that they're guaranteed never to break or wear out from normal use and now they're better than ever. The spindle design features a series of light threads out on the spindle and spindle colet. This design eliminates spindle slippage and takes the knuckle busting out of tightening the spindle lock while making spindle adjustments a snap. The Series II die sets are for the most popular rifle cartridges. This three-die set includes: sizer die, expander die, and seating die.
