If your only .002 off the lands I would seat a few at .020 off the lands and see how they chamber. .002 is not much to account for manufacturing tolerances of the bullets, and discrepancies in the reading you are actually getting with the tool. Mikej has some solid advise about using a modified case to find your OAL. If you really want to get in the weeds we can start talking about bullet ogive length vs cartridge OAL. You find where your bullet touches the lands and measure from base to ogive rather than tip of bullet. Much more consistent, and then you know your not in the lands. Hornady makes a tool for that as well.
