Steve,
Nice fable!
But a long time ago, before I could dream of affording an electronic chronograph, I built a ballistic pendulum, based on the information from P.O. Ackley's book, in the "crawl space" (about 3-1/2 feet high) of the house I then lived in. This was on the edge of a very small town in eastern Montana, and I guessed nobody would notice the thump of a .30-06 going off. None of the neighbors did, but the subterranean thump of a .30-06 definitely was a surprise to people who were visiting my first wife during my experiments.
