Muzzle velocities of 2600 ft/sec won't hack either the trajectory or the ho-ho test.
Your plots of a week or so ago focused solely on the 1 kilometer game. The .277 bullet in fact did not do as well even at that long range. These cartridges will need to do at least as well as the current M80 in the 0-300 meter and 300-500 meter games.
Any new cartridge will need to have at least 2750 ft/sec muzzle velocity to be competitive in the shorter game and to satisfy the TALAR (that looks about right) test that the senior decision makers are sure to apply.
