Typical instructions for a combined seating/crimping die:
Note: Crimping normally adjusts by screwing the die body further into the press. Seating normally adjusts by screwing the seating stem further into the die body. The following instructions MUST BE FOLLOWED IN SEQUENCE. DO NOT TRY TO SHORTCUT OR YOU WILL ENCOUNTER PROBLEMS AS YOU ORIGINALLY POSTED. Recommend you use an empty, unprimed case to make a dummy round while adjusting die.

1) TEMPORARY SEAT
Back off die body to totally eliminate all crimp AND THEN adjust seating screw to push bullet into a properly sized and belled case to desired seating depth. DO NOT LOCK SEATING STEM AT THIS POINT. THIS WILL NOT BE THE CORRECT SETTING LATER.

2) ADJUST CRIMP DEPTH
NOW BACK OFF seating stem/screw so it does NOT touch bullet at all during this step AND THEN adjust die body by screwing it in (trial and error) until you get just the crimp you want. NOW tighten the lock ring on die body to prevent die body from screwing into the press further.

3) ADJUST SEATING DEPTH
NOW raise the press ram fully (to insert dummy round into seating/crimping die), turn the seating stem in until it bears lightly against top of the bullet, AND tighten lock ring on seating stem. YOUR DIE IS NOW CORRECTLY ADJUSTED.

Good shooting and be safe.
