The funny thing about my ballistics program in the conditions when I shot to 1200yds with a 16" was that it showed me supersonic out to 1318yds. If they had really dry air and higher mv with the 20", the 1320yds doesn't seem too hard to believe for me. There's another forum member who has video shooting 12" plates at 1130yds.
