Have you tried working up the load again and this is the best you can do? Or is this the load that used to work in the old barrel? May just need to back your powder charge down.

I base this on my limited experience with my .308; 1 in 12 on a 20" barrel. 168, 175, 190gr, all can shoot sub-moa but it was never anywhere near the max recommended load; best accuracy was always obtained with charge weights towards the middle to bottom end of the scale.
