Rigorous testing in different atmospherically neutralized facilities at a 335 yard distance confirm the efficiency of the BERSIN device. Numerous shot patterns were established for ammunition set up using the BERSIN ammunition tester by the following: Industry (SIG Swiss Industry Union; Swiss Arms, a branch of SIG; Gruenig & Elmiger, Switzerland), as well as independent or governmental organizations (e.g. Austrian Ammunition Office Vienna). Other tests were executed by some top athletes in precision shooting. The shot patterns below depict the results that can be obtained by using the BERSIN device.

Please note that all patterns were established in a tunnel, at a distance of 335 yards, with a fixed barrel, and different calibers and ammunition types. The scale is slightly reduced, the actual circle diameter of the inner target circle is four inches. The left side shows the test results without the use of the BERSIN device, the right side proves the very obvious improvement after measuring and aligning the cartridges.
