Afaik it's an open question whether in an event like the statistical distribution of all bullet trajectories as we know it classically (e.g. based on some aerodynamics model)  is even remotely similar to the distribution of quantum states.

In others it could be that all classical variation boils up from little quantum fluctuations. But it could also be that the vast majority of quantum fluctuations led to the same result. If you then go further back and time and run the simulation again, because the next most dense group of multiverses might be one when he didn't fire the shot at all.

A few months ago this was brought up in  a Sean Caroll AMA.
