A surface, often circular and marked with concentric rings, bearing the perforations created by fired projectiles serves as a visual record of shooting accuracy. This object provides immediate feedback on aiming proficiency, weapon performance, and the external factors affecting trajectory. An example is a paper sheet at a firing range exhibiting these perforations.
Analysis of the pattern of perforations allows for adjustments in technique, equipment calibration, and understanding of ballistic principles. Historically, these marked surfaces were essential for training soldiers and refining weaponry, evolving from simple aiming points to sophisticated tools for evaluating firearms and ammunition. Their use extends beyond military applications, finding crucial roles in law enforcement training and competitive shooting sports.
