I have a 16" 22-250 and use Varget and H4895 with the lighter bullets. (It is 1x14 twist) I would think those powders would also work well for the 77gr through 80gr bullets.
Let us know how the brake works for you. I am thinking about rebarreling mine to a fast twist to shoot the 77s and 80s and I want to continue to use a rifle scope.
