If it makes you feel safer, send it to Kimber and complain about the barrel. They will either deny you or rebarrel it. When you get it back, it will shoot the same either way, because the problem is not the barrel.

It is not bedded properly yet. Did you read the thread above on ARAIG? It will help you understand a lot of what is probably going on. A heavier rifle masks most of these problems; a Kimber will not.
