What about steel ricochets?

All shot can ricochet. This is most likely to occur off rocks or other hard surfaces and, to a lesser extent, water and trees.

There is evidence that steel ricochets slightly more than lead, but this is in a more predictable path [1]. The fact remains that an unsafe shot with lead is an unsafe shot with steel.
