Like others have said... ford, chevy, dodge
And, as Broz hinted... If you're that hung up on accuracy, change calibers to one of the better known accuracy rounds. 6mmbr, 6x47 lapua, etc...
Of course, the rifle/ammo as a system and the smith doing the work needs to be up to the task or you really won't be able to discern the difference between quality barrel makers.
I would pick Shilen because it's close to home and I can drive there to discuss things. Perhaps there's a good Mfg near you?
Good luck!
