I dial. Primarily, makes the TRUST between you and the equipment happen.
Work my loads up at 300 to what the barrel likes, zero at 100, then start moving the bench to 200/300/400/500/600/700/800.
Moving and dialing also lets you know IF the scope is mounted correctly - should not be any left or right angling - straight up and straight down.
This ALSO gets YOU out shooting a little more. Not a lot, but, again, you will now trust the equipment.
