A Shotgun Approach to Calculating π

Here is a literal(!) shotgun approach for calculating an approximate value for π. I approve! (I think...)

Now let me quote from the arXiv paper (which is called "A Ballistic Monte Carlo Approximation of π"): "We compute a Monte Carlo approximation of {\pi} using importance sampling with shots coming out of a Mossberg 500 pump-action shotgun as the proposal distribution."
