In the video below, Forum member Eric Cortina shows how to install a Jewell Benchrest trigger into a Kelbly F-Class Panda action. You could follow the same simple procedure to install a Jewell in a standard Panda action. Kelbly’s sell both standard and long versions of the F-Class Panda action. Both versions feature integral recoil lugs in the front.

You don’t want to inquire about the price of a Bleiker competition rifle. As the expression goes, “If you have to ask, you can’t afford it”. At the Pardini USA booth at SHOT Show we saw a pair of black beauties — two “full-race” Bleikers, one a smallbore match rifle (.22 LR) and the other a 300m position rifle chambered in 6mmBR Norma. The combined price for the two rifles was a jaw-dropping $20,100.00. Yep, over $20K for the two. The 6mmBR rig was $10,200 while the smallbore rifle was $9,900.00.
Bleikers command such high prices because they win. At recent ISSF 300m and Smallbore Championships, Bleikers have been used by many of the medal winners. A gun is worth $10K if it can really put you on the podium or, better yet, deliver a world championship.
You are looking at $20,100 of Competition Rifles here. (Click Image for full-screen version.)
Take a look at this slick feature on the 300m gun. The adjustable cheek-pad automatically tilts up (for clearance) when you retract the bolt. That’s clever Swiss Engineering.
Forum member Preacher recently crafted a nice varmint rifle for fellow Forum member Dave 0. (aka “Waskawood”). But rather than buy an off-the-shelf stock, Preacher crafted this stock all by hand, starting from a laminated blank panel. He calls this stock project his “Axe Job”.

This stock is being used on a prairie dog rifle, chambered for a 17-caliber wildcat, the 17 VHA, which is based on an H&K 4.6x30mm parent case. With about nine grains of 300 MP pistol powder, the 17 VHA drives 20-grainers at about 3850 fps. (SEE details at end of article).
The ‘Axe Job’
Report by Preacher
I like carving with the laminates because all the lines are right there in front of my eyes, so it’s easy to follow along and get it just right, until it’s pleasing to the eye. I never use a template, I just keep checking the lines as I go along. I have all the needed equipment to power build one of these, but I really enjoy the time spent on the hand work. From start to completely ready-to-install, I’ll have about six (6) weeks into one of these stock projects. A lot of that is drying time for the clear coats.
A little work with the hand axe, after a trip through the band saw…
The majority of the laminated blank panels I use for my gunstocks are purchased directly from Cousineau Wood Products or from Rutply.com. You have to buy at least four full panels at a time, all the same color, but that will yield eight (8) stocks. Seems like I have a little over $150.00 in a blank large enough to start making a full-sized, benchrest-style stock.
A little work with a chisel…
A little work with a rasp. (Before I was rich and famous and could afford really good rasps, I used a good old horse shoe rasp.)
A little more work with the chisel…
Preacher’s Advice on Carving Your Own Stock
The one main advantage of being older that dirt, and tormented with MS the past 40 years, is lots of free time to enjoy what ever I can do these days, as long as I can set down to do it, and I can make a lot of wood chips setting down.
Any one can do this if they have the time to devote to it. All it takes is time and a good eye for details. I made a lot of firewood over the years, until I got the hang of it. Most all those problems were inletting, and screw hole spacing. Get those right the first time and you’re on your way….
A little more work with the rasp…
A few coats of Auto clear has it about buttoned up…
Micro 17 VHA Wildcat
Here’s the finished rifle built by Preacher for Dave, using the ‘Axe Job’ stock. Dave tells us: “Preacher chambered the rifle for the 17 VHA, a wildcat based on the H&K 4.6x30mm MP7 PDW case necked down to 17 caliber. There are numerous articles in the Varmint Hunter’s Magazine about it. This efficient little round shoots 20gr ballistic tips at 3850+ fps. That’s not too shabby for ‘nine point something’ grains of pistol powder.”
“My intentions for my 17 VHA rifle are to plop down in the middle of a PD town with my swivel bench and shoot prairie dogs. I also thought it would be a nice platform to test the accuracy of the cartridge. If I like the little round as well as I think, I plan to build a more practical rifle that I can carry. I really want to thank Preacher for his patience with me through this project, as it was my first custom build.”

Story by T. Logan Metesh forNRABlog.com
Since beginning in 1979, SHOT Show has become one of the premier firearms industry event of the year. As I was packing up amazing and historic guns from the NRA Museums for SHOT Show, I was led down a path of historical whimsy — what would SHOT Show have been like 160 years ago in 1855?
All of the today’s household names in firearms would have been in attendance: Remington, Colt, Smith & Wesson, Winchester, and others. Some of them were already well established; others were on the edge of greatness. Eliphalet Remington (right) would have been there. Already a well-known and respected businessman, he would have been representing the company he founded 39 years before in 1816.
Samuel Colt would have been in very good spirits. He had just renamed his company — Colt’s Patent Fire Arms Manufacturing Company — and had broken ground on a new factory that would open the following year in 1856. His revolver patent was also set to expire in 1856. Colt had recently fired Rollin White, a trivial matter at the time, but it would come back to haunt him.
Horace Smith and Daniel Wesson would have been there, too. At this point, the now-venerable firearms company had only been a partnership for three years. They would likely have been joined by one of their investors, Oliver Winchester, and showcasing their lever-action “Volcanic” arms.
Very shortly, Winchester would buy Volcanic, Rollin White would patent a bored-through cylinder that Colt had rejected, and Smith and Wesson would form Smith & Wesson Revolver Company utilizing White’s new patent.
As you can see, many of the technologies we consider antiquated were, at the time, revolutionary. Some of the designs we take for granted today were in their infancy in 1855.
Other lesser-known (and less successful) gunmakers hoping to capitalize on their new products would have been there as well. After all, there’s no better place to unveil new designs than at SHOT Show!
Thomas Wright Gardener Treeby (often known as T.W. Treeby) would likely have been at SHOT Show displaying his new 14-shot, .54 caliber chain rifle. Designed in 1854 and patented in 1855, these rifles were made in an attempt to create a successful repeating rifle design. The British military tested the gun with a 30-round chain, but the idea never caught on.
Rare, Antique Firearms on ForgottenWeapons.com
See the Treeby Chain Gun and other rare firearms on ForgottenWeapons.com. It is believed that only two Treeby Chain rifles were ever made. The 14 chain-linked “chambers” rotated into place via a sprocket (like on a bicycle), and each had a separate percussion cap. Watch this ForgottenWeapons.com video to see how it worked.

Sometimes superlatives really aren’t necessary. Just look at that target. Yes that is FIVE shots (although it truly appears like one hole). And it is centered! This remarkable group, measured at 0.039″, was shot by Lou Murdica in Phoenix on January 3, 2015. Lou drilled this group with his 6 PPC railgun. Rounds were loaded with Accurate LT-32 powder and Berger 65gr BT bullets. The target will be submitted to the NBRSA as a potential new 100-yard Benchrest record in the Unlimited (Railgun) Class. The current NBRSA record small group (Unlimited) is a 0.049 shot by Hall-of-Famer Gary Ocock in 2009.
This is a file photo with a different railgun.
This wasn’t the only tiny group shot by Lou over the weekend. Murdica shot a sizzling 0.1262 five-target 100-yard Unlimited Aggregate. That 0.1262 Agg will also be submitted for consideration as a possible record. Here are the individual group sizes: 0.104, 0.183, 0.201, 0.104, 0.039. At this match Lou won both the Unlimited and Sporter class. “It was a great weekend” Lou reported.
About the Gun
What kind of rifle can put five shots in one hole? Lou was shooting an Unlimited-class railgun. This return-to-battery rig (a Kensler railgun) allows the shooter to focus on firing at the perfect time for the conditions. Lou’s Kensler railgun (see below) features a Kelbly top-loader Grizzly action, Shilen 6-groove barrel, and March 10-60X scope. The Shilen is chambered for the 6 PPC cartridge. But there’s something special about this particular 6 PPC — read on….

Radical New Reamer Design from PT&G
Lou used a new chamber reamer from Pacific Tool & Gauge (PT&G) with special geometry in the leade/throat section. Called a “Bore Rider” (or sometimes “bore-runner”), this new reamer design cuts a staged, variable taper in the leade/throat area that is quite different than the taper in a typical throat. It’s a little hard to explain, so we’ve included the 6 PPC Bore Rider reamer print below. (Download the PDF file for a better view.) Experts should look at the leade angle(s), freebore, and throat dimensions. You may be surprised. Dave Kiff of PT&G says this Bore Rider design has worked successfully for other cartridge types/calibers as well. Apparently this design helps the bullet center up smoothly in the bore before the bullet engages “hard” in the rifling — or so we’ve been told.
Forum member K.W., aka ‘CigarCop’, has spotlighted his handsome long-range F-Class and Bench Rifle in our Forum’s Show Off Your Bat! thread. This is built with a BAT Multi-Flat action, Brux barrel, and a fiberglass McMillan F-Class stock. As you can see, it’s one handsome rifle. Be sure to click the image below to see the much more impressive wide-screen image!
The smithing was done by Bob Green and CigarCop was full of praise for Bob’s work: “I can’t really say enough about Bob Green, his attention to every detail and his ability to build an awesome shooting rifle… but once again he turned a pile of parts into a masterpiece! This irf was built on a Bat MB Multi-flat in .284 Win with a Brux 1:8.5″ twist barrel. It’s almost identical to my 6.5x47L that [Bob] also built. Once again, thanks Bob!”
Bob Green told us: “There was nothing really unusual about this build — this is the quality we try to maintain on all our guns. The barrel was chambered with the client’s reamer to a min-spec SAAMI .284 Win. The Multi-Flat BAT is pillar-bedded and bolted in, with no extra weight added to the stock. CigarCop provided the nice metal spacers on the buttstock and I polished them up. The finish is plain black but it looks good.”

We can predict, with some certainty, how long a light bulb will last (in use), or a shingle roof, or even a nuclear reactor. But how about barrels? Is there a way to reliably estimate barrel life based on known characteristics? This article explains one effort to quantify barrel life…
How long will a barrel last before the accuracy “goes south”? There are so many variables involved (powder type, bore diameter, bullet coatings etc.) that it’s hard to predict. You might say “Well, my buddy has a .243 and he got 1500 rounds before the throat was shot out” — those kind of comparisons can be useful, but they’re not very scientific, and they won’t help much if you’ve got a gun in a new chambering (such as the 6.5×47) for which long-term test results are lacking.
Is there a more reliable way to predict barrel life — one that will work for a broad range of calibers? Well, Forum member MikeCr has developed an Excel spreadsheet that accounts for a number of variables, and gives a pretty good estimate of useful barrel life, whether you’re shooting a .223 Rem or a 338 Lapua Magnum. Mike’s program predicts barrel life using five variables: 1) Bullet Diameter; 2) Powder Charge weight; 3) Powder Heat Potential (KJ/kg); 4) Pressure (in psi); and 5) Bullet Coating (yes/no). Mike provides a table with Heat Potential ratings for most popular powder types. The user needs to know the pressure of his load. This can be estimated with QuickLOAD.
You can download the lastest version of Mike’s spreadsheet below. You’ll need Excel or an Excel viewer to open the file.
Shown below is Mike’s Spreadsheet, with variables for a 6BR shooting 105gr “naked” bullets with 30.3 grains of Hodgdon Varget powder. The formula predicts 2401 rounds of barrel life. That corresponds pretty well to what we’d expect for a 6BR — about 2500 rounds.
Mike observes: “There has been a lot of discussion lately related to cartridge design and resulting barrel life. This is a really important factor to consider amongst a myriad of choices. Barrel life is controversial, and subjective. There are no clear-cut standards for comparison. But a few years ago, I put together a spreadsheet based on Bart Bobbit’s rule of thumb. It worked pretty good, only occasionally failing some tests when validated against posted barrel lives.
According to Ken Howell, I had to account for pressure. And Henry Child’s powder temperature testing provided another piece needed. So, I’ve tweaked it here and there to pass more tests. From 223 Rem to 300 UltraMagnum. Another element added, but turned off, is shot interval. I would need way more tests to lock in on this. But everyone knows, the faster you shoot, the worse the barrel life.
Anyway, another factor hard to define is ‘accurate’ barrel life. This cannot be quantified without standards. Barrels are replaced when expectations are no longer met. I feel that a [barrel] passes peak potential in a finite period due to throat erosion. But that don’t mean it’s toast, if it still shoots well enough. It’s just as likely that many of us never see that peak potential anyway. It’s a slippery thing. Point-blank BR competitors will toss a barrel when it leaves the 1s. I could get another 4000 rounds from it, and be content with its performance, I’m sure.”
NOTE: Mike says: “This spreadsheet may show a lower barrel life than you prefer. But it pretty well spotlights cartridges to stay away from if you plan much time at the range or in dog town.”
Editor’s Comment: Mike’s spreadsheet is a helpful tool, but it is NOT a definitive “take-it-to-the-bank” indicator of barrel life. Mike cautions that predicting barrel life involves so many different factors (including how hot the barrel is run), that the task is a bit like predicting tread life on car tires. Still, the spreadsheet is very helpful. It can certainly warn us that some chamberings (such as the 6-284) are likely to be barrel burners. That can help you make a smart decision when choosing a chambering for your next rifle.

This video shows the process of cut-rifled barrel-making by one of the world’s best barrel manufacturers. See Krieger barrels being made, start to finish. Krieger cut-rifled barrels have set numerous world records and are favored by many top shooters. The video show the huge, complex machines used — bore-drilling equipment and hydraulic riflers. You can also see how barrels are contoured, polished, and inspected.
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.
