Adjusting the die on every round is not...NOT how you seat bullets. You may get variance. Trying to account for it, you will never be able to re-create good ammo if you happen to find something that shoots well. Pick a seating depth off the lands, using your tools first to find out where they are: on a dummy round you soft-seat and work through your action. Altering seating depth is a way to 'tune' groups, but chasing a specific measurement is not going to work--your equipment is not designed for it.
