Velocities for the Hornady loaded AMAX 123 out of my 28" barrel averaged 2720 FPS. From a 20" they averaged 2590. At 2590 they are still supersonic supposedly at 1223 FPS.
Velocities for the Scenar Factory load were 2740 and 2600 respectively. At 2600 they would be still supersonic at 1257 FPS.
Using G7 drag numbers drops the Lapua by 57 FPS, but even so, its still supersonic at 1000.
Those are both factory loads, with powders not available to the public at this point, and real world testing is needed to confirm those numbers. I intend to try those loads at 1000 this year.
That said, I don't think either bullet is a real world bullet for military use, and some FMJ with a similar BC would be needed to carry that banner.

You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
