I’m going to vote rubber bullet.

Thinking out loud….it’s about energy transfer…the rubber bullet is more likely to transfer its energy to the target …as opposed to passing through and imparting very little energy.

Thinking out loud again…if the rubber bullet rebounds nearly 100% of the energy is imparted to the target? Excluding the energy dissipated, in the form of heat, due to the deformation of the rubber. Lead is less likely to deform generally speaking, compared to rubber.

….things are slow around here today
