Starting just touching the lands, not jammed but no jump, and then working up a load until you find pressure eliminates a coupla variables and concerns.
First, if you're running at safe pressure with the bullet touching the lands you'll be fine if you later have to seat away from them to find accuracy.
Secondly, you only have one way to go with your seating experimentation and that's seating them deeper.
Generally when I load kissing the lands and then find pressure I usually end right there because the accuracy is good and my speed is at max for that combo.
