In Quantitative Ammunition Selection, Charles Schwartz presents an accessible mathematical model that allows armed professionals and lawfully-armed citizens to evaluate the terminal ballistic preformance of self-defense ammunition using water as a valid ballistic test medium. Based upon a modified fluid dynamics equation that correlates highly (r=+0.94) to more than 700 points of manufacturer-and laboratory-test data, the quantitative model allows the armed professional to generate ballistic test results equivalent to those obtaines in calibrated 10 percent ordnance gelatin.
