Seating a bullet deeper will reduce the capacity of the case. Burning the same amount of powder in a slightly smaller space will raise pressure, but not usually enough to be a problem. If we’re talking about a really drastic change in seating depth, then the load should be backed down, and worked up again with the new seating depth.
