The question of barrel break-in is controversial. Some folks advocate an elaborate, lengthy cycle of shooting and brushing, repeated many times — one shot and clean, two shots and clean and so on. This, it is argued, helps barrels foul less and shoot more accurately. Others say minimal break-in, with patching and brushing after 10-15 rounds, is all you need. Still others contend that break-in procedures are a total waste of time and ammo — you should just load and shoot, and clean as you would normally.
We doubt if there will ever be real agreement among shooters concerning barrel break-in procedures. And one must remember that the appropriate break-in procedure might be quite different for a factory barrel vs. a custom hand-lapped barrel. This Editor has found that his very best custom barrels shot great right from the start, with no special break-in, other than wet patches at 5, 10, and 15 rounds. That said, I’ve seen some factory barrels that seemed to benefit from more elaborate break-in rituals.
What’s the best barrel break-in procedure? Well our friend Eric Mayer of Varminter.com decided to ask the experts. A while back Eric interviewed representatives of three leading barrel manufacturers: Krieger, Lothar-Walther, and Shilen. He recorded their responses on video. In order of appearance in the video, the three experts are:
Do I Need to Break-In a New Rifle Barrel?
Eric Mayer of Varminter.com says: “That is a simple question, [but it] does not necessarily have a simple answer. Instead of me repeating my own beliefs, and practices, on breaking-in a new rifle barrel, I decided to answer this one a bit differently. While we were at the 2016 SHOT Show, we tracked down three of the biggest, and most popular, custom barrel makers in the world, and asked them what they recommend to anyone buying their barrels, and why they recommend those procedures. We asked the question, and let the camera run!” Launch the video above to hear the answers — some of which may surprise you.
Long-Term Barrel Care — More Experts Offer Opinions
Apart from the debate about barrel break-in, there is the bigger question of how should you clean and maintain a barrel during its useful life. Some folks like aggressive brushing, other shooters have had success with less invasive methods, using bore foam and wet patches for the most part. Different strokes for different folks, as they say. In reality, there may not be one solution for every barrel. Different fouling problems demand different solutions. For example, solvents that work well for copper may not be the best for hard carbon (and vice-versa).
“Why worry about a little barrel fouling when the throat is subjected to a brutal 5,600° F volcano at 55,000 PSI? To investigate these and other questions about taking care of a match barrel, we spoke with a dozen experts and share their knowledge in this first of a series of articles.
After listening to folks who shoot, build barrels or manufacture cleaning solvents for a living, we concluded that even the experts each have their own unique recommendations on how to care for a match barrel. But they all agree on one thing — the gun will tell you what it likes best. Because the life expectancy of a match barrel is about 1,500 to 2,500 rounds, the objectives of cleaning one should include: preserve accuracy, slow the erosion, and remove fouling — all without damaging the gun. This article doesn’t claim that one cleaning method is better than the next. Rather, we set out to interject a little science into the discussion and to share some lessons learned from experts in the field.” — Chip Lohman

Ask 10 shooters about barrel cleaning and you’ll get 10 different opinions. This reflects that fact that different fouling problems demand different solutions. For example, solvents that work well for copper may not be the best for hard carbon (and vice-versa). To come up with the right solution, first you must understand the nature of the fouling in your barrel.
John Krieger Interview with AccurateShooter at SHOT Show:
The debate about the proper care of a match barrel is a hot one, spiked with folklore and old wives’ tales, Lohman said. He and his staff set out to set the record straight: “We tried to interject some science into the discussion of cleaning a match barrel,” he explained. In his article, Lohman writes:

For anyone interested in accurate rifles, this is absolutely a “must-watch” video. Watch blanks being cryogenically treated, then drilled and lathe-turned. Next comes the big stuff — the massive rifling machines that single-point-cut the rifling in a precise, time-consuming process. Following that you can see barrels being contoured, polished, and inspected (with air gauge and bore-scope). There is even a sequence showing chambers being cut.

At SHOT Show 2013 we had the chance to chat with legendary barrel-maker John Kreiger of Krieger Barrels. In this wide-ranging interview, John addressed a number of questions our readers often pose…. What is better for a 6mm, 0.236″ land or 0.237″ land? What are the pros/cons of various barrel types: 3-groove, 4-groove, 6-groove, 8-groove, and 5R? What types of land/groove configurations clean up more easily? (John says the 5R might be the winner there).
John also discusses barrel cleaning and he explains why it’s unwise to pull a dirty brush back across your delicate crown: “The problem comes from the fact that abrasive materials — powder and primer residues in particular — get embedded in the brush. Essentially that is how a lap works.”
When we suggested that Krieger Barrels might want to offer three-groove barrels in the future, John surprised us by revealing that he has been considering putting a 3-groove design into production. John says that, in theory at least, a canted-land 3-groove holds a lot of promise. John hopes to build some prototype 3-grooves to test. Krieger Barrels has a 300-yard underground tunnel where barrels with various land/groove configurations and calibers can be tested using a return-to-battery fixture. John admits that tunnel testing of barrels is “on the back burner” as his company focuses on filling orders. But he says that he has a strong personal interest in testing different land/groove configurations, different amounts of choke, and different internal dimensions. We hope we’ll be able to share some results from the Krieger Barrels test tunnel in the near future.

Krieger Barrels Inc. is a family-run business. Founder John Krieger now works with two of his sons in the business, Andrew (“Andy”) and Mark. At SHOT Show 2014 we had a chance to chat with John and Andy. John told us that he is very proud to work with his two sons. He said that Andy, who has a degree in engineering, brings an important skill set and a new level of scientific expertise to the business. On his part, Andy says that his father is a “great boss… and the best teacher you could have”. Meet this father and son barrel-making team in this short video.

How does Krieger Barrels produce such a great product year in and year out? It takes a lot of highly-skilled labor and some serious machinery to produce outstanding cut-rifled barrels. To illustrate the barrel-making process, Krieger has produced a fascinating video, filmed at Krieger’s production facility in Richfield, Wisconsin. This video shows the process of single-point, cut-rifled barrel-making start to finish. If you love big, powerful machines, you’ll enjoy this video. Its really quite amazing to see all that’s involved in the production of cut-rifled barrels.
