Resumen
Grid with support for the shot pattern of a sporting weapon. The shot pattern test is a technique that is usually carried out on a flat sheet on which the athlete studies the pattern of the pellets. After the impact of various cartridges on the sheet, it is painted again to cover the marks of the pellets. A test device that does not require the athlete to memorise the pattern and that allows the information to be recorded and eliminate possible errors of rebound of the pellet would be desirable. A shot pattern test system is described that consists of a predefined grid (1) of thin rods attached to a metal sheet (2) in the shape of a frame. At the top there is a roll of paper to slide a sheet of paper that can be photographed and recorded by cameras coupled to the system. (Machine-translation by Google Translate, not legally binding)
