Well, nothing is as simple as it should be. My gunsmith cut the barrel off just fine, but when he put it in the lathe and started turning it, he noticed that the barrel chamber is not centered in the barrel, so when he used his bit to do the crowning, it cut further on one side than the other.

And I sent this barrel back to T/C twice to check and they said there was nothing wrong with it! He let me look at it and you can tell without even measuring that one side of the barrel wall is thinner than the other side.......

Now he has to figure out a way to make the crown without the lathe. Will let you know how it comes out!
