Rifle Brass Sorting Experiment - Part Two

In the first part of this series, I spent a significant amount of time and energy measuring several dimensions of the same rifle cases, over and over for five firings. The goal was simple – to measure the relationship between the weight and volume of the cases. The theory-first approach I took does have its merits, but admittedly the results were a bit less clear.

Another valid way to approach this experiment is results-focused. To simply record the performance (muzzle velocity, score, etc) of each case, look for outliers, then try to better understand why they are outliers.
