As long as your marker is clean and the detents are out there will be no damage to the marker at all. Dry firing is no different than firing paint besides the balls traveling across the detents - thus why I would remove them to keep the bolt from slamming them.
your orings don't get anymore broken in if the bolt dumps the air or not, what does it is the bolt moving on the orings. So if you put a swab down your breech around a 1/2 an inch from the face of the bolt ( to allow the bolt to move but not dump the air) you can get a lot more done with a single fill.
