Krieger Barrels — Like Father, Like Sons

Krieger Barrels John KriegerKrieger 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 Raises Barrel Prices at End of December

If you plan to use a Krieger barrel for your next rifle build, better get that order in quickly. Due to a rise in the cost of steel, Krieger Barrels will add $15.00 to the price of a most stainless barrels, starting December 31st. In addition, the price of chrome moly barrels will also increase (typically $25) to become the same price as Krieger’s stainless barrels. (Previously the chrome moly barrels were cheaper than stainless.) The biggest price hike comes with large diameter barrels. There will be a large price hike on over-size diameter barrels ($100 increase on oversize blanks up to 1.450″ diameter.) Krieger says the price changes will “take effect January 1, 2012″, but it also states that price increases would be “implemented” on orders received “after midnight December 30th”. So, to be safe, get your order in before 11:59 pm on December 30th.

Krieger has also announced that it is halting manufacture of 17-caliber barrels as “the tooling on this caliber is too fragile”, and Krieger will no longer offer Custom Engraving. Here is the text of Krieger’s 2012 Price Changes Announcement:

Krieger Barrels — 2012 Price Changes

We [want] to give our customers a “heads up” on price increases to be implemented beginning with all orders received after midnight December 30th. Krieger Barrels has not increased the cost of barrels in two years, and now regretfully we find it necessary to do so. Below you will find a brief description of the changes. Detailed information will be posted as a catalog/website update shortly after Christmas. All price and service changes will take effect January 1, 2012.

Barrel Pricing:
The base cost of most stainless steel barrels will increase by $15.00. Chrome moly barrels will then be the same price as stainless making stainless and chrome moly barrels the same price. [This means the cost of chrome moly barrels will increase $25.00 on average.]

Oversize Diameter Pricing:
Oversize blank diameters up to 1.450″ will increase to $100.00 above the base cost in both stainless steel and chrome moly

Oversize blank diameters greater than 1.450″ up to 2.000″ will increase to $150.00 above the base cost in both stainless steel and chrome moly.

.50 BMG blanks (2.00″ x 36″) will remain the same price in stainless, but chrome moly will increase to the current stainless price.

Muzzle Threads:
We are eliminating the price difference between threading for a timed brake and an un-timed brake. The new cost to thread a muzzle to your machinist drawing or to match the device you send will be $125.00 either timed or un-timed. Fox River Brakes will remain $200.00 installed, and DCM/Service rifle barrels will continue to have no price difference between pre-ban and post-ban models.

Lothar Walther’s Woodall Explains Barrel-Making Methods

Lothar Walther barrelsAt the IWA Trade Show in Germany earlier this year, a correspondent for The Firearm Blog interviewed Woody Woodall, who runs Lothar Walther’s USA operation. While many shooters assume that Walther hammer-forges most of its barrels like some other European barrel-makers, in fact Lothar Walther USA uses the button rifling technique for most of its US-made barrels.

In the video below, created for The Firearm Blog, Woodall explains that button rifling involves some extra steps to ensure a good result: “The extra work that goes into it is that you’ve got to make rifling, stress relieve it, and have it come out the right size. And it takes a lot of skill to do that. Lothar Walther invented button rifling in 1925, if a better way of making rifling came out, we’d be glad to go to it.”

Woodall explains that hammer forging is a good method for mass production, but it is costly to set up: “Hammer forging is relatively new, it came out in 1934, but did not come into prominence until the 1950s…. But the cost of [hammer forging] in the world today is getting above what the market will bear for barrels. [Hammer forging] is more complicated. As the hammers hit the barrel the barrel gets longer, but the hammers have to hit uniformly so the barrel [stays] straight. There’s a higher failure rate in that. There’s also some surface delamination that can occur, and some other issues. So if you’re hammer forging, you really have to pay attention to the details. So, it’s like button rifling, only ten times more complicated. It’s for super-high-volume production… The large companies tend to use the hammer forging, intermediate size companies tend to use the buttoning, and craft companies tend to use the cut rifling. All three [methods] can make an equally accurate barrel.”

SHOT Show Report: The Boys from Bartlein

Bartlein BarrelsWisconsin’s Bartlein Barrels currently produces some of the most accurate cut-rifled rifle barrels in the world. We had a chance to chat with Bartlein barrel-makers Tracy Bartlein and Frank Green shortly after the doors opened at the 2010 SHOT Show in Las Vegas. Frank and Tracy weighed in on some of the “hot topics” in the barrel-making business: Gain Twist and the advantages of single-point cut rifling. In this interview, the “boys from Bartlein” discuss current trends in barrel-making, including what’s “hot” in short-range benchrest and the emergence of 7mm barrels for F-Class Open competition. Tracy also offers his opinions on cut rifling vs. button rifling, and he explains how modern technology has helped make modern barrels “better than ever”.

John Krieger on the Art and Science of Barrel-Making

John Krieger barrel-makerJohn Krieger is widely recognized as one of the wizards of barrel-making. Krieger cut-rifled barrels are widely recognized as among the best you can buy. You’ll find Krieger barrels winning in all major disciplines, from “point-blank” benchrest to 1000-yard prone matches. John Krieger, and his staff of highly-skilled employees, are strongly committed to quality manufacturing and customer satisfaction. When asked to describe his “business philosophy”, John stated: “Everybody in the company has one concern. That’s just to make the best barrels we can make — hopefully the best barrels that have ever been made — and to try and keep (as much as humanly possible) every customer happy.”

During the NRA Annual Meeting, we had a chance to chat with John Krieger. John shared his views on a variety of technical topics, ranging from gain twist rifling, to advances in steel quality and manufacturing methods. John answered questions about barrel contours, barrel fluting, and stress relieving. John also provided some sage advice on how to protect your barrel’s crown during the cleaning process.
