When I look at a new barrel blank with a bore scope, I love to see the inside look really slick and smooth. This characteristic of slick and smooth is typical of Button rifle barrels, Hart, Shilen, Lilja, and Pac Nor that I have had. When I started shooting Cut Rifle barrels, I noticed that some are just rough inside and may take a longer break in period with more copper fouling.
I have had a lot of Kriegers, and their Service after the Sale has proved to be stellar. If a production problem happens on a barrel, where the barrel has issue, the barrel maker should make it right. I had only one Krieger that has had a problem over the years, and the management at Krieger could not wait to get that barrel out of my hands. I sent the barrel back, and they responded with "What length and contour do you want as a replacement?"! Krieger is well known for Customer service, and for me, I don't know how you put a price on a commitment to customer satisfaction as the Krieger people exhibit.
