I'm not sure what your point is; but the chances of a 5.56mm round travelling 100m AFTER it has fragmented are pretty much zero. You are looking at a round that is only 40-75gr typically to begin with... depending on what they strike and how they strike it, the largest remaining chunk after fragmentation might be anywhere from 31gr to 4.7gr.

An irregular piece of metal lacking any kind of aerodynamic properties is going to shed energy very quickly, and the smaller it is, the faster it is going to shed that energy.

Now, if the round doesn't fragment; because say it is a bonded HP round that retains all of its weight and just deforms to a less ballistically efficient shape (or a lightly constructed varmint round that sails through a window), then it might keep on trucking through the neighborhood.

Well, although not a revelation, this part is certain true. If it weren't true, we'd all be using the same thing and it wouldn't be a source of controversy.
