Yeah it's got me confused. Weighing with Hornady beam scales - they're pretty good.

I am wondering whether it could be a genuine large ES, as @Pommy suggests - I just ran the data and there is only 1" or so vertical spread at 300yd. So that could be within the 3" group, and potentially could be a lot tighter if the spread is reduced.
