WildRose I understand and agree about stress and out of true. But the OP has stated the rifle shoots 1/2 moa consistent groups.
I am going to assume , and that is not a scientific conclusion at all. But in my mind from what has been discussed about this condition in this thread. If it were my rifle it would be stripped down of all scope mounting. Rail would be inspected and if no problems found reinstalled with proper bedding to insure it stayed true and flat on top. Then ring alignment checked and scope remounted. Then I would examine with a fine tooth come the actual tracking of the scope and ALL inputted data into the ballistic program especially in regards to scope turret calibration, powder temp variation, BC and I would get a velocity average from an Oehler 35 or a Magneto speed
The facts that the results from shooting at 100 yards and the results at 900 and 1000 are in complete disagreement indicates multiple problems to me.
It will be interesting for Big Cat to install a new scope with no other modifications and using the same data in the ballistic app and see what results he has then.
Just my opinion for what its worth.
I agree. The problem is which I'm relating perhaps not as clearly as intended. Mine would shoot sub MOA for 3 shots and be fine if I let it cool all the way down.
If I did not the accumulation of everything wrong with it suffered badly with heating and got progressively worse with each successive group.
If I chased those groups trying to bring them back to zero it went to hell fast and when I'd come back to re zero I'd be lucky to even be on paper.
I'm with you, I think the problem is in the scope mounting or scope itself just tossing out other possibilities.
