Falcon, I've nailed quite a few hogs with hard cast in my .45 Colts. As Semi pointed out, they are damn near impossible to beat on penetration but they just don't expand to create serious internal damage. As you have figured out by now I'm sure, hogs, like deer, can be a pretty dang tough critter to put down right on the spot without a CNS interruption. You will find those hard casts to be some serious bone breakers so if you are dead set on using them, go for the shoulder joints or head and neck shots and you will see them doing the nose dive shuffle. Anything else and you will see them going even further than they have been.
