The moment does his at 275 for about 10 hrs.
Watch the 2 Franklin BBQ videos on youtube about his brisket tips.
He shows how he trims it, tests it during cooking, wraps it with butcher paper at about 4-6 hrs and then lets it rest.
I've tried his tips twice now and both briskets were WAY better than my previois attempts which were done at lower temps (225 or so).
