You sure your rifle still groups the 120s? The POI shifts you describe are the classic symptoms of a bedding issue or improperly torqued action bolts.
That is how team Savage tines their rifles. It's a bit more than "someone's theory".Std7mag :
Interesting but that is someone’s theory and not Savages recommend practice . I spoke with them because a Savage was the rifle that was shooting those double groups . They did not recommend any adjusting and simply said 40lbs on each screw . That said I like your method and did similar. When I did my torque test I tried multiple configuration and methods . I agree start low-ish and only tighten in increments. I did not like loosening the retighten to new spec .
I am in the camp of long bullets barely sticking into short cases because I cut very deep throats.I'm with the camp on long bullets in short cases. I got a Hornady OAL guage for all my rifles. MAGIC.
A given barrel has the same harmonics (vibration frequencies) across all loads because its shape is the same for all of them.Did you watch his Video??? He doesn’t jam his bullets he finds the Jam then backs off .02 off that then starts adjusting his seating depth .003 until he finds two consistent nodes.
The OP hasnt found the right barrel harmonics for his load. His ES/SD look good but barrel harmonics are off
In THIS instance it would appear to be action screw torque.
