Not given "NOT LOUGH, High"

me and my mate just did that challenge on legendary with 10 skulls on new Alexandria we got the 300000 points (round about) then we finished the mission and no challenge i have saved the video in theatre it is so annoying!!!

Did you get 250,000 each? Because I think you need to score at least 250,000 individually. I did it on the Pillar of Autumn, solo, getting to the MAC gun early. As soon as I got 250,000 the challenge popped up.

Yup, it’s not a cumulative score of 250k, it’s an individual score.
