A heavier bullet will normally use less powder. Most times the heavier bullet base is deeper in the case with the same OAL because it has greater length. If you are using 230 grain data you will need to use use a lower max level to keep pressures in a safe range. You can check this by comparing the same type bullet in different weights with the same powder in published data.
