Dider I've seen some incredible long range shooting over the years every one I know would be proud of that.
At that range the "cause" could be anything from the slightest updraft, slightest change in wind velocity if it is either a head or tail wind, or simply the slightest shift in your point of aim due to the type and thickness of your crosshairs.
It could also very easily just be caused by ES in your loads.
When your "error" is sub 1/4 MOA I wouldn't go nuts trying to figure it out.
Congrats on some absolutely outstanding shooting.
