Along the lines of your initial answer, steel shot has lead to huge advances in wads and chokes for better patterns, as well as higher velocity loads. Though the old timers would never admit it, I think shotguns have the potential now to be more effective than they ever were with lead.

Lead Free Ammo. Allowed harder alloy bullets to be pushed at increased velocities with less terminal fragmentation.
