About Frank
Frank is a staunch defender of liberty, a connoisseur of fine firearms, and a firm believer in the Second Amendment. I built this calculator because I believe every free man and woman deserves the tools to understand their craft, whether it's defending the Constitution, defending home and property, punching paper, competing in matches, or ethically harvesting game.
Remember, freedom isn't free, but good ballistics data can be! I built this tool to empower shooters of all skill levels with professional-grade calculations that were once only available to military and competitive shooters. Because an informed shooter is a better shooter, and a better shooter is a freer American.
"The right to keep and bear arms shall not be infringed—and neither shall your right to know exactly where your bullets are going!" - Frank
