One was to shoot different manufacturers’ lots of the same brand of Lapua match ammunition in an extremely accurate rifle to demonstrate accuracy differences between those lots. Three different series of tests were performed. It is important to note that the accuracy shown in the chart is not necessarily for five consecutively fired groups.

Shot dispersion at various distances is an angular measurement, so average group size at twice that distance should be less than 0.500 inch, and that is possible when shooting on an indoor range. The same also goes for some of the rifles put together by custom builders. When top-tier match rifles, such as those built by Anschutz, Bleiker, and Walther, are matched with their preferred ammunition, they are capable of consistently shooting five bullets inside 0.250 inch at 50 yards.
