My head hurts taking all this in...how about an amusing anecdote for those of us in Rio Linda? Some years back when the Commonwealth countries were still using .303's in competition, it was common knowledge that the Mk7 .303 174 gr ball round was barely capable of holding 2,5 moa at 100 or 200 yards. But, it got better at 300 and , Katy bar the door at 600, theory was the damn thing straightened up and flew right. Embarrassing several competing countries, including us Yanks.
