Again you need to figure if you're willing to limit your shot placements. If you'll only take perfect broadside shots into the boiler room, an expanding bullet might be the better choice. If you add quartering shots and heavy bone, then IMHO quality hard cast or mono metal solids are the better choice.

Which get's back to my original comment about shot placement, as it is tied into the bullets you use and the shots you take, or don't take.
