Being a truck gun, was it fired with a slight obstruction from the truck's floor?

Previous owner didn't shoot it that much, the rifling looks fine. I had cleaned it previously but did so again and used some foaming bore cleaner on it to see if it showed any copper. Came out without a trace of blue. Going to retorque the action screws and shoot some 150's through it tonight.

A bore brush, some patches, and a couple of dabs of JB would have the cleaning question settled pretty quick be it metal fouling, carbon, or whatever.

The barrel should be fine unless he has shot several thousand rounds. I would say in excess of 5-8 thousand unless he just kept shooting with a very hot barrel. There have been reports of barrels shooting 10-30 thousand rounds with virtually no loss of accuracy in a 308.
Double check the crown first, check the ignition and possibly put a new spring in it. Check scope and mounting again. Do a deep clean with copper solvent that sits in the barrel, and clean until all traces of copper are gone. This may take a couple of days.

I know you said you re-crowned the barrel but what did that entail. I would throw my money on the crown still being buggered up. Fouling causing that kind of issues don't seem too likely to me. I mean I have seen accuracy diminish with fouling but to the point of taking a sub moa shooter to a 4-6moa gun...

Have smith check to see if the barrel has loosened up had a guy on another site have his 1/2 moa gun go to crap and the barrel backed off slightly. Tightened it and its back to a 1/2 moa gun.
