I remember years ago selling point for Shilen was they don't straighten barrels.
I was talking to gunsmith that does my barrels and he said last 8 to 10yrs barrels have been better in part customer are little smarter. You can do a search find all kinds of information how to straighten barrels etc.
One thing I notice ordering barrels they seem to more interested send you a barrel finished length so all you have to do is crown it.
