With the exception of the Lee locking rings, which you set each time, standard lock rings have a set screw or a cross-bolt screw to fix their positions on the die. This is intended to relocate them to the same place each time. However, you want to check a test round with them each time to be sure you didn't get them tightened a little differently than at the previous session. After while you'll get the feel of it.
