Krieger Barrels — Like Father, Like Sons
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.
How Krieger Barrels Are Made (MUST-WATCH video — one of the best we’ve ever featured).
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.
Here is a time-line of the important barrel-making processes shown in the video. You may want to use the “Pause” button, or repeat some segments to get a better look at particular operations. The numbers on the left represent playback minutes and seconds.

Krieger & Co never sent me a barrel that I could out-shoot. Granted, I had a great machinist/gunsmith that fitted them. But, the rifle still needs a very good barrel to shoot exceedingly well.
Please define “out-shoot” a barrel in the context as used in your statement above.
Very cool presentation.
Good on them for making the video. Maybe they didn’t show “everything,” but I know of other barrel makers that are super paranoid their miraculous, stupendous trade secrets might be discovered, and would never let a video camera in the shop. To me, this openness shows they are both honest and have great confidence in their product.
