While a black bears bone structure is beefier than your average deer they actually have a thinner skin........they are not an overly tough animal to bring down or shoot through, and any set-up you would use to cleanly take a whitetail is capable of harvesting a bear cleanly.
I personally would stay away from the large cutting diameter mechanicals in the vent of a large bone hit, but I would feel more than confident using exactly the same set-up that I would carry into the deer woods.
Steelheads will be a fine Black bear head.
As with any animal it's all about shot placement, but there is nothing about a black bear that warrants a need to "Bulk Up"
