Hornady's Custom Grade Series II 3-Die Set for 444 Marlin provides a lifetime of reloading, guaranteed never to break or wear out from normal use. The spindle design features a series of light threads cut on the spindle and spindle collet, eliminating spindle slippage and taking the knuckle-busting out of tightening the spindle lock while making spindle adjustments effortless. This three-die set includes a sizer die, expander die, and seating die for reliable, consistent reloading performance. Safety Note Proper die setup and adjustment are critical for producing safe ammunition. Follow published load data and standard reloading safety practices.
