Subject rifle is the 10MLII.
When new with factory barrel, there wasn't enough scope adjustment for vertical (don't recall too low or too high). I shimmed one of the bases for correction. After the first season, I replaced the shim and used Burris Signature rings with offset inserts for the correction.
Factory barrel got replaced with .458 barrel, and the ring offsets had to be offset the opposite direction for correction.
Later decided I wanted a dedicated .451 barrel, so: Replaced that barrel with a .451, and added a Vortex Viper. It then shot 15" to the left! So far, cannot get Signature offset inserts in 30mm other than those which come with the rings. The 10* offset did get the job done, however, but with quite a bit of scope adjustment. I later changed the breech plug and had to readjust the barrel for headspacing the new plug. I replaced the 10* offsets with the regular 0* offsets. POI changed to shooting 15" high!
If barrel threading in the action was not true, would it not shoot the same direction relative to aim point with each barrel (assuming barrel threads are true)?
The factory recoil lug was replaced with a better after-market lug.
I'm beginning to wonder if the problem is the barrel nut? Is it possible it needs to be trued? How can one check it to see if that is the problem?

IMO you are right on with the barrel but. If the nut isn't square to the threads I believe it will have more pull on the barrel than the recoil lug and will cause what you are seeing. I would replace the nut rather than attempt to true it.

Danno,
That's what Northland Shooter Supply said when I started buying recoil lugs from him. He said barrel nut is often worse than the recoil lug for alignment issues with the factory savage.

Thanks, guys for confirming what finally sunk into the ol' beaner! A new nut from Jim it is! Have dealt with him in the past....great guy to do business with.
That just may help solve my leakage problems as well!
