If your Savage bolt gun in '06 shoots straight , your done .

If you want to rebarrel it check MidwayUSA,gunparts, they have had 338.06 and 35Whelan barrels as cheap as $120. I am impressed with both of mine.
If you want a better tube check Shilen for Savage replacement barrels.
Also glance at Sharp Shooter Supply,McGowan Barrels,E.R.Shaw and others.
Barrel $120+,wrench $35,headspace gauge15+, dies.
Do a web search for Savage rebarreling ,you needed a small project anyhow!

You will remember a curve of your wagon track in the grass of the plain like the features of a friend."
