I remember it clover leafing 3 shots at 100 yards. Now with the same loads it puts 2 real close but the 3rd shot always seems to wander an inch or so....
So ... lemme get this straight. You have a single shot. You are wigging out about the third shot moving an inch in POI.
Sounding like a solution in search of a problem, doesn't it?
Enjoy your very cool rifle!
