Anyone know how common it is for a barrel to be out of round? I ask because I picked up a shilen match select from Northlander (awesome to deal with) and took it in to have a muzzle break installed. I went to check on it today and the smith had it still chucked in the lathe. He switched it on to show me and that thing had wobbles like you wouldn't believe. Highs and lows all over the place. In fact the break was just over OD of the barrel and after it was installed one side would be even and the other over OD. Now he has to buff it down to match up. Should I be expecting a little better out of one of these barrels?
