Hornady New Dimension Expander Dies User Manual

Before using your new die, it must be thoroughly cleaned. A rust

preventative is applied at the factory and must be removed before

using the die. We recommend Hornady One Shot Cleaner and Dry lube

or any commercial solvent will suffi ce. The expander die is designed to

put a slight “bell” or fl are on the case mouth. For uniform fl aring trim

all cases to proper length.

To adjust the expander die, fi rst place a case in the shell holder and

raise the ram to full extension. Thread the expander die into the press

until the expander touches the case mouth. Raise the handle and

screw down the die in quarter-turn increments, each time inspecting

the case mouth, until the mouth of the case has been fl ared just

enough to start a bullet into the case mouth. Tighten the lock ring

against the press, and lock it in place with the set screw. Keep in

mind that excessive fl are can eventually shorten case life, and may

keep the case from properly entering the seating die.
