Very nice. For a factory stick, factory ammo, and only a little tuning you are shooting almost .5MOA.
That is a good value for the dollar spent in anyone's book in my neck of the woods.
Have you tuned the trigger, or done any further modifications or "custom" work ( lapping the lugs, scope mounting re-config, recrown factory barrel, reloaded brass that was fire formed )?
Very nice report. I dig that software. Free you say? Might have to give it a try....
