The goal of this study was to characterize shooting performance differences between universally zeroed weapons zeroed by a weapons expert and individually zeroed weapons zeroed by the shooter, as well as sight system types and target distance m. Independent variables included two zeroing methods, four weapon sights, and four ranges 100400 m. Dependent variables included shooting accuracy, radial error, and shooting response time. Individual factors such as shooter experience or ability and ammunition velocity properties may both have covariate effects. There were some significant differences between universal and individual zero. There were also several significant covariate effects that included velocity data that were strongly associated with dependent variables as well as individual shooting experience. Trends indicated significant advantages for magnified optics over iron sights and nonmagnified optics. A shooting model to examine multiple connections among different variables in the shooting process is recommended.
