while a 185gr. round going 1000 fps from a 5" bbl may still get 900 fps from a 3.5" bbl.
That may be true, but the 230 does not rely on velocity as much to work. What really matters is which one expands to the largest diameter when penetrating 12-18 inches. Assuming that is the 185 is pure speculation and there is no reason to assume it is the answer.
