I completely agree!
It appears you're an experienced shooter, so we'll not discuss basics, as it appears you've tried various loads and techniques with that Kimber.
That said, have you checked the bedding? Especially around the recoil lug. Is the stock touching the barrel anywhere? Action screws not too long and snugged properly? Is the crown perfect? Scope mount screws not too long and touching the barrel or bolt?
Have you checked fired cases on a concentricity gauge? Any anomalies there would indicate chamber issues.
The WSM family is not really known to be stellar accurate, but you're right, you should/could expect more from a rifle in this price range. If all fails, I'd contact the Mothership for guidance, as if this is as good as that rifle can do, it's still not worthy of the Kimber name. I'd make the call to sort it out if you can't determine the accuracy issue, as the factory advertising touts how accurate these light rifles are.
My Kimber 84M Varmint in 204 will cut ragged holes at 100 yds with my pet load. Yours should do at least half as good as that. Good luck with the rifle, and let us know how it shakes out later.
