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.
Criterion Barrels Inc. (CBI) has a policy of rewarding excellence. As a way of supporting top shooters, Criterion will provide a new, free barrel to any shooter who sets or ties a national record when using a Criterion product. To explain, you get a new Criterion barrel for free if you set (or tie) a national shooting record using a Criterion barrel on your rifle.
Criterion Barrels hopes to increase awareness of its free barrel for record sectors program. Over the last few years a number of F-Class and vintage military competitors have benefited from this program, receiving a complimentary barrel of their choice after setting a new national record in their shooting discipline. Past record breaking shooters have included David Mark Honeycutt (with a 300-yard F-Class score of 600-50X), Samantha Huhtala (four records set in 600-yard F-TR competition), and Victor Betzold (M1 Carbine with a score of 375-6X).
Criterion may, in the future, create a rewards program for winners of national, regional, and local rifle matches. Potential earned rewards by match winners could include equipment sponsorships, barrel discounts, and free apparel items.
Set a Record with a Criterion Barrel? Then Give Criterion a Call…
If you or someone you know has set a pending national record with a Criterion barrel, have the shooter contact Criterion Barrels. Send email to contact[at]criterionbarrels.com or call (262) 628-8749.
Once the shooter’s information is verified and the record is confirmed by the governing body of their appropriate shooting discipline, the order will be processed and shipped to the new record-holder.
About Criterion Barrels, Inc.: Criterion Barrels, Inc. was founded in 1999 as a division of Krieger Barrels, Inc. in response to demands of rifle builders and firearms manufacturers for quality match grade barrels at a lower cost. Our company is now completely independent from Krieger Barrels, featuring a separate facility, personnel, and ownership.
There are two more days to save. We recently talked to Lester Bruno, owner of Bruno Shooters Supply. Lester explained that he has extended Bruno’s Holiday Season Sale through Monday, January 11, 2016 at 5:00 pm MST. Lester told us “This has been really popular with our customers. Right now you can get 5% off plus free shipping [to the lower 48]. Tell your Bulletin readers that this sale will run through Monday but that’s it…” Note: This offer is limited to one shipped box per customer per day. Hazmat fee will be charged on Hazmat items, though the Free Shipping otherwise applies to all items.
Here is Lester Bruno with some of his large inventory of bullets from Berger, Sierra and other brands. And yes, Bruno’s has premium barrels in stock.
Advancements in barrel technology in recent decades have been impressive. Today’s premium barrels deliver accuracy that could only have been dreamed-of decades ago. And now a new development promises to help barrel-makers craft the most uniform, consistent, and stable barrels ever.
What’s the new technology? You may be surprised. It’s not a surface treatment, or a cryogenic bath. The latest development in barrel manufacturing is Degaussing — the process of de-magnetizing metal objects. Degaussing is now used in many industries to uniform metallic products and to prevent unwanted interactions with magnetic fields. LEARN MORE.
Degaussing is the process of decreasing or eliminating a remnant magnetic field. It is named after the gauss, a unit of magnetism, which in turn was named after Carl Friedrich Gauss.
At the recent IWA show in Germany, Vallon GmbH, a German manufacturer of degaussing machines, told us that two major Wisconsin barrel-makers have purchased Vallon industrial degaussing units. The units sold to the American barrel-makers are similar to Vallon’s EMS unit show below. This can degauss (i.e. de-magnetize) 50 barrel blanks in one pass.
The Vallon degausser works by passing the barrel steel through a coil. Vallon explains: “The density of magnetic field lines is at its maximum in the coil centre, and is strongly decreasing towards the outside. If a ferromagnetic work piece (steel) is introduced into the coil, the field lines are concentrating and flooding the work piece. The conductivity of steel is up to 800 times higher than that of air. Degaussing is done during a continuous movement of the work piece, leading out of the coil. Decreasing field strength is achieved by a slow extraction from the coil.”
How Degaussing Improves Barrel Steel and Rifle Performance
So what does magnetism have to do with barrel performance? How can degaussing help make a barrel better? Vallon’s scientists tell us that degaussing has three major benefits. First, it aligns ferrous elements within the barrels, strengthening the steel at the molecular level from the inside out. Second, by reducing static surface charges, degaussing reduces chatter during drilling, which creates a straighter bore with a better surface finish. Lastly, there is evidence that degaussed barrels produce slightly more velocity. When a copper-clad bullet spins through a non-degaussed (magnetically-charged) barrel, this creates waste electrical energy. The energy expended reduces velocity very slightly. You can see this effect yourself if you spin a copper rod in the middle of a donut-shaped magnet. This creates an electrical charge.
Here a barrel is checked after degaussing with a Vallon EMS. The meter records a zero magnetic value, showing complete degaussing success.
Degaussing Will Add $50.00 to Barrel Cost
We know what you’re thinking: “All right, degaussing seems beneficial, but how much will this add to the cost of my new barrel?” Based on off-the-record conversations with two barrel-makers, we estimate that degaussing will add less than $50.00 to the cost of a new barrel blank. That’s a small price to pay for greater accuracy and barrel life.
Ask a Sailor — F-Class Champion and U.S. Navy Veteran Explains Degaussing
We asked reigning F-TR Champion James Crofts about barrel degaussing. A U.S. Navy veteran, he immediately understood the potential benefits of this process. “I served in nuclear submarines. Since before World War II, the U.S. Navy degaussed its subs and smaller warships. This had many benefits. Principally, it helped reduce the risk of triggering magnetic mines. But that wasn’t the only benefit — the degaussing process gave the steel greater resilience and longevity. And that’s why the Navy degaussed non-combat vessels as well. Will a degaussed barrel shoot better? Honestly I can’t say. But based on my Navy experience, I bet degaussed steel will be more uniform and will last longer. I’m glad somebody is trying this out on rifle barrels. Put me on the waiting list!”
The above photo show a U.S. nuclear submarine during a degaussing (also called “deperming”) session. This reduces the vessel’s electromagnetic signature, making it more stealthy. Deperming also adds to the vessel’s longevity. With steel-hulled ships, static electricity builds up as the hull slices through the water. A powerful, constant static charge will cause the steel to deteriorate. Degaussing (deperming) helps prevent this, extending the life of the hull.
Report by Dick Grosbier for IBS
Over the weekend of September 13-14, 2014, the Ashe County Wildlife Club of Laurel Springs, North Carolina hosted the 44th annual IBS 100/200 Score Nationals. Sixty-two shooters were on the line for the event, including many record holders and major match winners.
The shooters traveled from as far away as Florida, Wisconsin, and Maine. Considering the miserable weather forecast for Saturday it was really a pretty nice day. We did have rain but thanks to the way the roof overhangs the firing line (photo below) the competitors stayed dry, only the target crew got wet. In spite of this they did an excellent job — they were fully prepared as the forecast was for a very high percentage chance of rain. Saturday got into the high 70s and actually got a little muggy. Sunday was overcast cooler and little if any rain fell.
This was my third visit to Ashe County this year and I must say it gets better each time. They have a great crew of people and a wonderful facility. There are 30 covered benches located next to a very large (40’x160’) reloading, scoring, dining, and clubhouse facility. The entire range is built on the side of a big hill. They have literally moved thousands of cubic yards of dirt (50,000+) to build this facility.
Breeden Busts Record — 1000-59X Two-Gun Total May Be Best Ever!
This year’s IBS Score Nationals saw a performance for the ages. Dean Breeden put together one of the most impressive feats of score shooting in history. Dean’s Two-Gun total score (for VFS and Hunter) was a stunning 1000-59X. This is a pending new Two-Gun IBS world record. Think about that — this means that Dean did not drop a single point through twenty (20) total matches (i.e. 20 targets), while alternating between two different rifles, one with a puny 6-power scope! That’s 100 “Tens” in a row on 100 Bullseyes, without fail. That’s really a remarkable achievement. As least Dean does not have to console the old record-holder, because the pre-existing record, 1000-52X, was set by (you guessed it), Mr. Dean Breeden. In besting his own record by seven Xs, Breeden won the Two-Gun award at this year’s IBS Score Nationals and earned a new entry in the record books. Congrats to Dean!
Bullet-maker Randy Robinett was amazed at Breeden’s 1000-59X performance. “Some years ago, I held the Two-Gun score record with a 999-52X. What Dean has accomplished with his 1000-59X is truly noteworthy — this really is a BIG deal. Let me tell you, getting 1000 points is really hard to do. You have to switch between two different rifles, and adjust from a high-power scope to a 6X scope, changing rests and equipment all the time. This is very tough.”
Looking at the Equipment List (Editor’s Comment)
The Equipment List from the 2014 IBS Score Nationals is quite revealing. As you’d expect, this match was very much a 30-caliber affair, but we were surprised to see such dominance by cut-rifled barrels, and Hodgdon H4198 powder.
1. All of the Top 15 VFS shooters ran cut-rifled barrels. There were mostly Bartleins and Kriegers, with two Brux barrels and one Rock Creek.
2. Hodgdon H4198 is definitely the powder of choice, used by 14 of the Top 20 VFS shooters. Federal 205M primers were used by at least 13 of the Top 20 shooters.
3. Randy Robinett’s BIB bullets were the most popular, used by four of the Top 10 shooters.
4. Every VFS shooter and every Hunter Class shooter was running a 30-caliber cartridge. Most VFS shooters ran 30BRs, but the 30×47 cartridge was favored by half the Hunter shooters.
5. Two gunsmiths smithed six of the Top 10 rifles. Three were by Mike Niblett and three were by Sid Goodling (who also smithed #11 and #12).
6. BAT Machine actions are still #1. BAT actions were used by 14 of the Top 20 shooters.
Mike Niblett (above) had a typical VFS rig: BAT action, Krieger cut-rifled barrel, with a Nightforce 12-42X scope. Mike used H4198 of course, but he shot Hill bullets in his 30BR, rather than BIBs.
Many 250s with 20 or more Xs Shot on Saturday
Saturday, at 100 yards, it was the Kevin and K.L. show. Kevin Donalds Sr. and K.L. Miller took the lead in Varmint For Score, and Hunter classes respectively all day long. Kevin turned in a fine score of 250-22X followed closely by Dean Breeden with 250-21X. Dean was just barely short of the win all weekend in both classes. Mike Niblett was third with 250-20X, ahead of five other 250-20X scores based on tie-breaker. There were four 19X and eight 18X scores. K.L. Miller turned in a fine 250-18x score in Hunter Class followed closely by Peter Hills and Frank McKee (both with 250-16Xs). It was moderately windy and switchy all day and since the Nationals involve shooting each record match from a different bench you essentially faced a new set of conditions each time you came to the line.
‘Top Guns’ at the Score Nationals: Kevin Donald Sr., K.L. Miller, and Dean Breeden.
Sunday it was overcast and cooler but not as rainy. Anthony Isner stepped up and took the lead in VFS class turning in a fine 250-16X score. Second place went to, you guessed it, Dean Breeden. Dean’s 250-15X was followed closely by Kevin Donalds Sr. also with 15X. In Hunter class it was Randy Jarvais’s turn to win an Aggregate. Randy’s 250-9X score beat out Dean’s 250-8X and Miller’s 250-7X scores.
In the VFS Grand Aggregate, Kevin Donalds Sr. topped the field with 500-37X, followed by Dean Breeden with 500-36X, and Anthony Isner with 500-34X. K.L. Miller won the Hunter Grand Agg handily — his 500-25X easily topped Dean’s 500-23X and Randy’s 500-20X totals. The IBS 2-Gun award went to Dean Breeden with a record score of 1000-59X. This is a potential new 2-Gun record as he bested his own record by seven Xs.
Praise for the Match Organizers and Staff
All in all it was a very well run match at a great new facility. This was the first Nationals event to be held there but it will not be the last. Hats off to E.T. Weaver and his helpers. The target crew deserves special mention. They were very good and very fast. A match with full bench rotation can be a nightmare for any target crew but these guys handled it like old pros even though it was their first-ever attempt. Well done guys and gals!
The Ashe County Wildlife Club put on a great event, complete with delicious country Barbecue.

When visiting Phoenix last week we dropped in at Bruno Shooters Supply (“Bruno’s”). This place is truly a treasure trove for anyone interested in precision shooting. Barrels, custom actions, stocks, scopes, loading presses, dies, and accessories — you name it, Bruno’s has it. We were amazed to see one bin with literally hundreds of new Krieger barrel blanks. This Editor was tempted to purchase a couple just to avoid delays in the future.
Lester Bruno has been running Bruno Shooters Supply for nearly four decades. A very successful benchrest shooter himsef, Lester knows about accuracy. He prides himself on carrying the best products made, and he shoots what he sells. He’s also a very talented gunsmith. In the video below, Lester talks about building accurate rifles.
Bruno’s also maintains a vast inventory of premium reloading components: Lapua brass, Hodgdon/IMR, Alliant, and Vihtavuori powders, and all the major primer brands. You want bullets? Berger, Sierra, Lapua, and Nosler bullets are stacked floor to ceiling!
Lester Bruno has been selling rifle components and reloading supplies for 37 years. He now has a very good idea of what precision shooters want most, and his staff works hard to keep the most popular items in stock. Bruno’s has a large inventory of Nightforce scopes, and Lester recently placed an order for 1000+ Krieger barrels — that number was a new high for the Wisconsin barrel-maker.
Bruno’s has huge inventories of high-demand items, such as Krieger barrels, BAT actions, and McMillan stocks. Lester’s company, now the largest distributor of BAT actions in the nation, usually has 100 or so BATs in stock. Right now Bruno’s has over 500 custom barrels in stock in a wide range of calibers, from .17 up to .416. There’s a very good selection of the most popular calibers, twist rates, and contours. Bruno’s also has 100 or so McMillan stocks in inventory currently.
Gunsmithing Services After touring the warehouse, we had a chance to chat with Lester about precision gunsmithing and component selection. In addition to running the business, Lester Bruno somehow finds the time to build custom rifles — very accurate custom rifles, we should add. Forum member Terry Balding recently won the NBRSA 600-yard Nationals using a Lester Bruno-smithed 6mm Dasher. (Terry also finished third in the NBRSA 1000-yard Nationals with the same rifle.)
In our interview, Lester pointed out that he builds more than point-blank benchrest rigs these days. Lester also crafts long-range benchrest, F-Class, and even hunting rifles. Because Lester has plenty of actions, premium barrels, and stocks already on his shelves, he can normally offer a very good turn-around time on custom builds. Keep in mind however, that Lester is not your guy if you’re looking for a fancy wood project. Lester prefers to use fiberglass stocks, such as McMillan. Lester also noted that he will start carrying H-S Precision stocks very soon.
