I know that when you change primers you need to back the powder off and work back up, but would a different primer ( large to magnum primer ) change the seating depth?
Or is it once the seating depth is established for a particular bullet and barrel then it becomes a fixed and known quantity? which would only move if you are chasing the lands but of course still stay the same distance away or in.
