I am glad you and others have had good luck. I have also had had flutted barrels shoot well. I have had several that did not. ( flutted by some of the best )Please donot take my word for it. After the expense of the barrel,chambering,flutting ,coating and putting brakes on, you are ~$1200. Now spend time testing. If it doesn't shoot well, maybe your gunsmith takes his time testing, or because you just laid out 4,5,or 6k on your custom rifle why not $400 $600 on a Pro for load development. If it still does not shoot good call Krieger or Bartlein explain you have $1500 in a barrel and you are not satisfied with the accuracy. They will explain policy. I am a slow learner, I now buy them flutted from the manufacture or I do not flute. ( I am trying to help )
Question: Why will Kampfeld flute a Bartlein 2b, but Bartlein will not?
