I was holding about 2 feet right at 850 yards, kentucky windage. There was a cross wind from the right somewhere midway to the target, but just a slight breeze AT the target (and coming from the other direction).
I mostly shoot under 500 yards and the 55s hold their own. If I shot long range regularly I'd shoot something else like the 105s. But under 500 yards I see no worthwhile benefit of shooting a different bullet, the windage advantage of a high BC bullet is marginal.
