McPhee makes some of the best barrels in the world, bar none. If non-Canadian barrels are that contemptable and you don't want a 30 I would recommend Ted Gaillard. His barrels are certainly accurate, but he only button-rifles, he doesn't cut.
Mick McPhee only makes true custom barrels and he is highly selective about the types of firearms he builds, concentrating on precision match rifles and he only sells barrels if he does the installation to ensure that they are installed properly. Mick is a complete and total perfectionist....Perfectionists like that are rare, and a real pleasure to meet. He'll also give you the straight goods on which Canadian barrels he likes, and which American barrels he has found to be "lacking" in quality control... very interesting indeed.
