I would be cautious with 3/4, and feel like 1 full turn will be too much. 1/4 to 1/2 after you dial it down to touch the case mouth of the loaded round should do it.one with "Resistance + 3/4 turn" and one with "Resistance + 1 full turn".
Measure diameter at the case mouth and just below it until you get to a point halfway down the part of the bullet in the case.
Not 9MM, but you get the idea.
