TEN Shots in 0.303″ (0.289 MOA) at 100 Yards
Look at that target showing TEN shots at 100 yards, with eight (8) shots in the main cluster at the top. The ten-shot group measures .303″ (0.289 MOA), as calculated with OnTarget Software. Not bad for a handgun — a very nice bolt-action XP-100 pistol! What do you think, can your best-shooting rifle match the 10-shot accuracy of this XP-100 pistol?
Report by Boyd Allen
This story goes back a few seasons… this remarkable XP-100 pistol belongs to Dan Lutke, a Bay Area benchrest shooter who publishes the results for the Visalia matches to the competitors and the NBRSA. He has been an enthusiastic competitor for an number of years, at various ranges, notably Visalia and Sacramento. The action is a Remington XP-100, to which a Kelbly 2 oz. trigger has been fitted. On top is an old Japanese-made Tasco 36X scope (these were actually pretty darn good). The Hart barrel (a cast-off from Dan’s Unlimited rail gun) was shortened and re-chambered for the 6x45mm, a wildcat made by necking-up the .223 Remington parent case. The custom stock/chassis was CNC-machined by Joe Updike from 6061 Billet Aluminum to fit the XP-100 action and mount a target-style AR grip with bottom hand rest. The gun was bedded and assembled by Mel Iwatsubu. In his XP-100 pistol, Dan shoots 65gr custom boat-tails with Benchmark powder.
This diagram shows the most common 6x45mm wildcat, which is a necked-up version of the .223 Remington parent cartridge. NOTE: The dimensions for Dan Lutke’s benchrest version of this cartridge may be slightly different.

The late Bill Myers was recognized as one of greatest rimfire smiths who ever lived. Myers crafted many match-winning, record-setting rimfire benchrest rigs. Here we feature one of Bill’s most interesting creations — a clamping action that allows a rimfire barrel to be indexed (rotated) around the bore axis.
Bill was a creative thinker, and his own exhaustive testing has convinced him that barrel indexing can enhance accuracy in rimfire benchrest guns. Myers did acknowledge that, particularly with a very good barrel, the advantages of indexing may be subtle, and extensive testing may be required. Nonetheless, Myers believed that indexing could improve rimfire accuracy.
Indexing with the Myers’ Clamping Action
To index the barrel, Myers simply loosens the three clamping-bolts and rotates the barrel in the action. Because there is no thread to pull the barrel in or out, the headspace stays the same no matter how much the barrel is rotated. In other words you can rotate the barrel to any position on the clockface and the headspace remains unchanged.
The Challenge of Barrel Indexing With a conventional barrel installation, employing a shoulder with a threaded tenon, it is difficult to index the barrel. Even with a cone breech (photo right) that eliminates the problem of extractor cuts, you’d have to use shims to alter the barrel index position, or otherwise re-set the shoulder each time you screwed the barrel in further.
Clamping Action Allows Barrel to Be Rotated to Any Position
Bill has come up with a masterful solution to barrel indexing. He designed and built his own prototype custom action that clamps the barrel rather than holding it with threads. The front section of the action is sliced lengthways, and then clamped down with three bolts. A special bushing (the gold-color piece in photos) fits between the barrel and the action. By using bushings of different inside diameters, Bill can fit any barrel up to an inch or so diameter, so long as it has a straight contour at the breech end. To mount the barrel, Bill simply places the fitted bushing over the barrel end-shank, then slips the “sleeved” barrel into the front end of the action. Tighten three bolts, and the barrel is secure.
The model 1911 pistol, designed by John Moses Browning, is an American classic. Originally manufactured as .45 ACP military pistols, modern 1911s have evolved to be superb competition pistols, and carry pistols. With a Single-Action-Only (SAO) configuration, the 1911 design is different than most modern pistols. You must have the hammer cocked to fire a 1911 — like a single-action revolver. But the positive side of the Single-Action design is than modern 1911 pistols enjoy superb triggers with very positive release and fast reset. There is a reason the 1911 design is the basis for so many modern competition pistols.
In today’s Saturday at the Movies feature, we showcase videos that cover the history, design, and function of 1911-type pistols. We also include videos that explain how to field-strip a 1911 and how to accessorize/upgrade 1911 pistols.
Operation of 1911 Pistol with 3D Animations
Here are two excellent videos that show how a classic 1911-type pistol functions. 3D computer graphics animation offers a X-Ray view inside the pistol, showing how cartridges feed and how the slide cycles during the firing process.
How to Field-Strip and Re-Assemble a 1911 Pistol
There are a few tricks to field-stripping a 1911-type pistols, and it helps to have a couple specialized tools. This helpful TFB-TV (The Firearm Blog) video shows the process of disassembling a 1911 pistol from start to finish, and notes components that require lubrication or special attention.
History of the Classic Model 1911 Pistol
The model of 1911 pistol is an American classic with a long and illustrious history. These two videos cover the interesting origins of the 1911 pistol, and explain how J.M. Browning designed the remarkable 1911 pistol which became the iconic American sidearm of the U.S. Military, the longest-serving pistol in American military history.
A fascinating article by Rock Island Armory covers the complete evolution of the 1911 pistol, including its earlier prototype variants, starting with the model of 1905. SEE: Road to the 1911 Article (with Model 1905, 1907, 1909, and 1910 prototypes).
Over time the 1911 design has evolved into many variants, including the modern “race gun” used in rapid-fire pistol competitions. Here is an STI DVC Open model fitted with a C-More sight, and front compensator.
Pistol Shooting Skills Demonstrated with 1911
How to Grip a 1911 Handgun Properly
World Champion pistol ace (and 18-time Bianchi Cup winner) Doug Koenig demonstrates how to grip a handgun. While the fundamentals are demonstrated on a 1911 pistol they are effective for establishing a proper grip on any handgun.
Trigger Press and Trigger Control
In this video Champion shooter Doug Koenig talks about key techniques that apply to all pistol marksmanship — not just speed shooting “on the clock”. With any handgun, Doug explains, you should focus on consistent trigger control. You want to avoid yanking the trigger or anticipating recoil.
How to Accessorize Your 1911
This six-part series by Brownells provides step-by-step instruction on how to accessorize your 1911. The videos cover changing out the mainspring housing, magazine release, slide release, hammer, guide rod, and installing a group gripper. If you want to upgrade your 1911, these videos are worth watching.
In our Shooters’ Forum, there’s an interesting thread about a very light hunting rifle. Featuring a Defiance ultra-light all-steel action, this 6.5×57 Lapua lightweight tips the scales at just 4.93 pounds including scope and rings! For reference, a half-gallon of milk weighs 4.3 pounds, so this rifle is LIGHT! Here’s a report from the proud owner who built the rifle for a future Kodiak Island Alaska mountain goat hunt.
Ultralight Rifle Report by Forum Member Dave
I decided I wanted the challenge of a Mountain Goat hunt after I turn 60. It was the perfect excuse to put together an ultralight, something I had wanted to do for years. I wanted to see how light a bolt action rifle could actually be. My goal was to stay under 5 pounds, without going to a Titanium action, including rings and scope. I knew this would be difficult but I did manage to achieve the goal.
I started with a Defiance anTi model Rem Model 7 short action. This is an extremely smooth action that weighs just 19.2 ounces in this size. I had Carson Lilja of Lilja Barrels program a barrel taper to my dimensions for a 6.5mm 1:8″-twist stainless, 3-groove 22″ barrel. As fitted in the rifle, the barrel is free-floated except for the first inch or so forward of the action.
Other rifle components are: Bix n Andy Dakota trigger, aluminum trigger guard, blind magazine with an aluminum follower, titanium action screws, and a Leupold 3-9X lightweight optic in Talley rings. I also had an aluminum adapter installed in the for-end to accept a magnetic mount Javelin carbon fiber bipod.
The rifle was chambered up in 6.5×47 Lapua by my friends at Sportsman’s Outfitters in Knox, Pennsylvania. Then I sent the barreled action to Wayne at Oregunsmithing (Pendleton, OR) to have a Kevlar stock built. The stock weighs a whopping 14 ounces! When it came back I had everything Cerakoted (see bottom photo before coating). This stock was a full custom, built around my barreled action. Wayne’s work was reasonably priced with a 3-month turn around.
Excellent Accuracy — 5/8″ Three-Shot Groups at 100 Yards
Now it was time to shoot the rifle and I was not disappointed. It shoots both Barnes TTSX 100s or Swift Scirocco II 130s into 5/8″ at 100 yards. Off a bipod at 400 yards, three go into 3″ or so. This thing is crazy light even though it wears a 22″ barrel.
Without scope and rings, before Cerakoting the action and barrel, this 6.5×47 rifle tipped the scales at a mere 4.20 pounds (67.2 ounces). Check it out:
Put the same load in a variety of barrels (with the same length and chamberings) and you’ll see a wide variance in muzzle velocity. In fact, it’s not unusual to see up to 100 fps difference from one barrel to the next. We demonstrated this with a comparison test of Lapua factory ammo.
Chron Testing Lapua Factory Ammo
At our Southern California test range some years ago, we chronographed Lapua 105gr 6mmBR factory ammo in three different 8-twist barrels of similar length. The results were fascinating. Lapua specs this ammo at 2790 fps, based on Lapua’s testing with its own 26″ test barrel. We observed a speed variance of 67 fps based on tests with three aftermarket barrels.
Barrel Velocity Variance
Brand ‘S’ and Brand ‘PN’ were pre-fit barrels shot on Savage actions. Brand ‘K’ was fitted to a custom action. All test barrels were throated for the 100-108 grain bullets, though there may have been some slight variances in barrel freebore. With a COAL of 2.330″, the rounds were “jumping” to the rifling in all barrels.
Among the four barrels, Brand ‘PN’ was the fastest at 2824 fps average — 67 fps faster than the slowest barrel. Roughly 10 fps can be attributed to the slightly longer length (27″ vs. 26″), but otherwise this particular barrel was simply faster than the rest. (Click Here for results of 6mmBR Barrel Length Velocity Test).
IMPORTANT: Results Are Barrel-Specific, Not Brand-Specific
These tests demonstrate that the exact same load can perform very differently in different barrels. We aren’t publishing the barrel-makers’ names, because it would be wrong to assume that ‘Brand X’ is always going to be faster than ‘Brand Y’ based on test results from a single barrel. In fact, velocities can vary up to 100 fps with two identical-spec barrels from the SAME manufacturer. That’s right, you can have two 8-twist, 26″ barrels, with the same land-groove configuration and contour, from the same manufacturer, and one can be much faster than another.
Don’t Demand More Than Your Barrel Can Deliver
We often hear guys lament, “I don’t get it… how can you guys get 2900 fps with your 6BRs and I can only get 2840?” The answer may simply be that the barrel is slower than average. If you have a slow barrel, you can try using more powder, but there is a good chance it may never run as fast as an inherently fast barrel. You shouldn’t knock yourself out (and over-stress your brass) trying to duplicate the velocities someone else may be getting. You need to work within the limits of your barrel.
Factory Ammo Provides a Benchmark
If you have a .223 Rem, 6mmBR, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, 6.5×55, .308 Win, 30-06, or .338 LM Rifle, we recommend you buy a box of Lapua factory-loaded ammo. This stuff will shoot great (typically around half-MOA), and it can give you a baseline to determine how your barrel stacks up speedwise. [Editor’s NOTE: The original test was conducted in 2008. The velocity of current-production Lapua factory ammo might be higher or lower, so your results may vary.]
When you complete a new 6mmBR rifle, it’s definitely smart to get a box of the factory ammo and chronograph it. That will immediately give you a good idea whether you have a slow, average, or fast barrel. Then you can set your velocity goals accordingly. For example, if the factory 6BR ammo runs about 2780-2790 fps in your gun, it has an average barrel. If it runs 2820+ in a 26″ barrel (or 2835 fps in a 28″), you’ve got a fast tube.

Henry Repeating Arms will offer two limited-edition models to mark company’s twenty-fifth anniversary. The two rifles, one rimfire and one 44-50 Centerfire, pay tribute to the beginnings of Henry Repeating Arms as a company and the origins of the lever action rifle’s enduring legacy in America.
25th Anniv. Edition .22 Rimfire
Twenty-five years ago, from a small factory in Brooklyn, New York, Henry Repeating Arms began shipping the now world-renown model H001 Classic Lever Action .22. Since then, the company has sold more than one million of the rifles.
Now, the company is introducing the 25th Anniversary Edition (model H001-25), which features semi-fancy genuine American walnut furniture and an engraved, nickel-plated receiver cover with 24-carat gold plated highlights. The handsome rifle comes with a fully adjustable semi-buckhorn rear sight, and a hooded blade front sight. The tube magazine holds 15 rounds of .22 Long Rifle, 17 rounds of .22 Long, or 21 rounds of .22 Short. The Classic Lever Action .22 25th Anniversary Edition is limited to 5,000 units with a $1,130 MSRP.
25th Anniversary .44-40 Henry Original Deluxe
The rifle is a faithful recreation of the original patent except for more robust materials and the concessions needed to accommodate the more modern .44-40 WCF cartridge, of which the rifle can carry 13 rounds. Other features include a folding ladder rear sight, a brass blade front sight, a hardened brass crescent buttplate with a period-correct storage compartment, and near full coverage engraving on the hardened brass receiver flats. The H011D-25 New Original Henry Deluxe Engraved 25th Anniversary Edition is limited to only 2,500 units with an MSRP of $3,990.
Above, Henry Repeating Arms CEO and Founder Anthony Imperato selects the rosewood blanks to be used for the buttstocks on the New Original Henry Deluxe Engraved 25th Anniversary Edition rifles. “It was love at first sight with this rosewood, and I immediately knew we needed to do something special with it,” said Imperato. “The richness and warmth of the wood is the perfect complement to our hardened brass and polished blued steel.”

Readers often ask “What’s the difference between a Weaver scope rail and a Picatinny Rail?” The answer is not as simple as it seems. The dimensions of a Picatinny Rail should be consistent (from one rail-maker to another), since there IS a government spec. Conversely, there is some variance in “Weaver-style” rails. The width of the groove is the most important difference between Picatinny Rails and Weaver-type rails. “Mil-spec” Picatinny rails will have a grove width of 0.206″ while Weaver rails typically have a narrower, 0.180″ groove width.
Does your rifle have a Weaver Rail or Picatinny Rail? Check the dimensions to be sure.
Brownell’s has a helpful GunTech™ Article that discusses the Picatinny Rail vs. Weaver Rail. That article explains:
What are the differences between the ‘Picatinny’ and the ‘Weaver’ systems? The profile of the two systems is virtually identical. Depending on the quality of the machining done by the manufacturer, the two systems should be indistinguishable from the profile. The key difference lies in the placement of the recoil grooves and with width of the grooves. MIL-STD-1913 (Picatinny) grooves are .206″ wide and have a center-to-center width of .394”. The placement of these grooves has to be consistent in order for it to be a true Picatinny MIL-STD system. Weaver systems have a .180” width of recoil groove and are not necessarily consistent in a center-to-center measurement from one groove to the next.
In many instances, a Weaver system has a specific application that it is machined for, so interchangeability is not necessarily an issue. A MIL-STD-1913 system must adhere to the specifications listed above in order for it to be considered MIL-STD, since the military desires uniformity in the recoil grooves to allow for different systems to be mounted on the weapon with no concern for compatibility.
Now, what does this mean? Boiled down, it means that accessories designed for a Weaver system will, in most cases, fit on a Picatinny system. The reverse, however, is probably not the case. Due to the larger recoil groove, Picatinny accessories will not fit a Weaver system. There are, of course, exceptions to every rule, but for a good rule-of-thumb, [full-width] Picatinny won’t fit Weaver, but Weaver accessories WILL fit Picatinny.
As a Labor Day Weekend bonus, we thought we’d celebrate the beauty of highly-figured wood with a collection of custom rifles. In our Shooters’ Forum, there is a long-running Gun Glamour thread that showcases many beautiful wood-stocked rifles. Today we feature some very handsome rifles from that Forum Thread as well as other rifles we’ve featured in the Daily Bulletin.
Two F-Open Beauties with Walnut Laminates
Cerus-stocked Special from Cigarcop
Forum member Keith W. (aka “Cigarcop”) of KW Precision LLC is a talented riflesmith whose projects display outstanding finish work and attention to detail. Keith does some of the best bedding work we’ve ever seen. Back in 2018, Keith built a stunning .284 Win F-Class rig for a shooter in Delaware. It’s a beauty, that’s for sure.
Check out the stunning Cerus F-Open stock. This features multiple laminations with highly-figured Walnut on the sides. This certainly ain’t your “off-the-shelf” laminated stock. This just shows the beauty that can be achieved with carefully-chosen lamination layers (plus 12 coats of clear).
This beautiful F-Open rig features a laminated wood stock with stunning figured walnut on the outside.
A Beauty for the Boss (of Grizzly.com)
This F-Class rifle belongs to Shiraz Balolia, Chairman/CEO of Grizzly Industrial. Shiraz finished the stock himself: “I installed the bottom wider track for my rear bag and also carved out the finger grooves in the grip. The blank was quite long so I cut off approximately two inches from the front end of each stock and also deepened the large tracking cavity under the fore-end. I went ahead and inlaid my name in Mother-of-Pearl on the Walnut stock.” The stock was then sent to Sims Guitar Finishing for clear coating with “wet look” finish. This rifle is chambered for the .300 Shiraz wildcat, an improved .300 WSM.

Beautiful Rifles from our Forum Gun Glamour Thread
Here are a variety of handsome wood-stocked rifles from our Forum Gun Glamour thread. In that thread, member Kurz posted a dream gun owned by a friend in England. Kurz included a quote from a book created by the rifle’s owner: “There, with my father’s words ringing in my ears, I shall take that ‘step forward’ and order a perfect machine based on the Mauser ’98 action, built from metal and wood by master craftsmen who truly understand that ‘reliable’ and ‘mechanical integrity’ have as much relevance today as they did all those years ago.”
A gun can “shoot dots” and still be handsome. Here is a short-range benchrest rifle with a stunning, exhibition-grade Walnut stock. Forum member Josh B found this beauty.
Forum member JRS submitted a stunner from Europe. This beauty features a truly exquisite piece of wood with elaborately engraved receiver. It also has escutcheons and special metal work on the grip.
Lever-action Falling Block rifles can be beautiful too. This one features a color case-hardened receiver and handsome two-piece fancy wood stock. This was submitted by Forum member Kurz who notes: “Besides exhibition grade walnut, I like the variations available in spalted maple for rifle stocks.”
Here is member Oldduc’s Stevens 44 1/2, .38-55 Black Powder Cartridge Rifle, with an extra .218 Mashburn Bee barrel. Very nice blueing along with the figured wood stocks and fore-arms.
A competition rifle must be “performance first”. But that doesn’t mean they can’t be handsome too. Forum member XTR’s rifle, an F-TR rig, features Maple wood with Bubinga tips.
Here is “something completely different” — a classic lever-activated Martini Martini Cadet chambered in .20 Vartarg (rimmed). Look at the figure on that fore-end. Remarkable!
And wood can work for Benchrest rifles too, when cleverly fashioned in thin carbon-reinforced laminates. Photo from member mdman352.
“Wood is Good” — as demonstrated by all the rifles showcased above. In the photo below, master stock-builder Doan Trevor handcrafts a highly-figured wood stock.
372,000,000 views! Today’s five feature videos have, collectively, been viewed 372 million times on YouTube. Today’s Saturday special features five remarkable animated firearms videos from Matt Rittman, a very talented computer graphic artist. Matt employs multiple software programs to create these incredibly detailed animations. His software tools of the trade include Cinema 4D, Substance Painter, and Corona renderer. Don’t think this is easy. Some of these videos took over 500 man-hours to create. Enjoy!
AR-15 Full Animation — Components and Function
While there are other AR-15 animations on YouTube, we think this is the most accurate and creative, showing the function of a wide variety of components, including the bolt carrier, extractor, trigger, stock buffer, safety system, forward assist, and mag release. It also shows modes of a military M16, showing 3-round burst fire, and full-auto, employing disconnectors and auto sear. If you are planning to assemble/disassemble an AR, this is definitely worth watching start to finish. This video has recorded over 2 million views in just three weeks!

Mauser Kar-98K Bolt Action Rifle video
This elaborate 3D animation shows how a Mauser-type Karabiner 98 Kurz (aka Kar-98K) bolt-action rifle works. Substance Painter was used to create the wood stock texture. Creator Matt Rittman states that this 3.7 minute video took over 500 man-hours to create. You have to admire the dedication involved in that kind of hard work.
This 3D animation video shows the popular Glock 19 (Gen 4) pistol. This modern, polymer-framed, striker-fired pistol has constant trigger pull for all shots. Some folks call this a DAO (double-action-only) trigger but that’s not really correct. Unlike the Model 1911, on a Glock there is no external safety on the frame or slide. The trigger “shoe” (the part that contacts finger) includes a central blade. This prevents the gun from firing unless the trigger is depresses normally. Glock calls this the “safe action”. The creator, Matt Rittman states: “Cinema 4D was used to create each individual part, as well as animating everything. Substance Painter was used to create the main textures. Corona renderer was used to render everything. This animation [with 84.6 million views] took me over 500 hours to create.”

Pump shotguns are essential firearms for hunting and home defense. The clever design of pump-action shotguns make them reliable even when feeding large diameter, blunt-ended 12 gauge shot-shells.
With 226 million views, this AK-47 video might just be the most-watched firearms tech video on YouTube. The video highlights the design features the account for the AK’s legendary reliability. For viewers with an eye to detail Matt adds this clarification: “The firing pin does NOT puncture the bullet primer. It just strikes it against the anvil, initiating the firing sequence.”
With a conventional barrel installation, employing a shoulder with a threaded tenon, it is difficult to index the barrel. Even with a cone breech (photo right) that eliminates the problem of extractor cuts, you’d have to use shims to alter the barrel index position, or otherwise re-set the shoulder each time you screwed the barrel in further.
