If you are going to use a micrometer style seater die, you really need to be measuring your chamber. Those seater dies are great when you are "chasing the lands" to maintain a consistent jump for your match bullets as the throat wears.
But then again, if you are chasing the lands of your throat, you are competing at a level where you need a 150 dollar seating die.
