Threshold:
[INDENT]Equal or better the vertex and wind drift of the 7.62X51 M80 at 300 and 1000 metres when using a 20-inch barrel.[/INDENT]
Objective:
[INDENT]Equal or better the vertex and wind drift of the 20-inch barrel 7.62X51 M80 at 300 and 1000 metres when using a 14-inch barrel.[/INDENT]
Rationale: The trajectory of the 7.62 from standard-length barrels is a known and accepted performance level. Any new ammunition type will need to perform at least as well in the emerging new and shorter standard barrel lengths. Meeting or beating the 7.62 trajectory at either 300 or 1000 meters assures that the trajectory performance will be better than that of the 5.56 M855
