energy=1/2 mass x velocity squared. Same mass, same velocity, question to me is how is the terminal energy dissipated. I think rubber will "knock down" more in that all of its energy is dissipated faster at the surface of the wood versus the lead bullet which loses energy over a greater period of time as it bores into the wood.
