409,000,000 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 233 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.”
As a Labor Day Weekend bonus for our readers, 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.

Credit our buddy Joe Friedrich for this simple yet effective accessory for your benchrest rifle. Joe shoots a .22 LR benchrest rig with a barrel tuner. When he added weights to his tuner, he found his rifle no longer balanced well. He wanted to add some weight in the rear without drilling holes in the stock. He also wanted the weight to be removable, and easily placed on another rifle in his stable. He wanted a weight that could be moved from gun to gun as needed.
At a local sporting goods shop Joe found a 1.5-lb ankle weight that comes in a padded, tubular elastic cover. It’s like a 1.5-lb sausage in a soft, stretchy nylon cover. (Imagine a really fat, heavy bungee cord). Joe simply attached a plastic zip tie at the end to make a loop that fits perfectly over his buttstock. CLICK HERE for full-screen photo.
To “tune” the rifle’s balance, Joe just slides the ankle weight fore and aft on the stock. We have tried this moveable ankle weight on a variety of different BR stocks (including a McMillan Edge) and it worked perfectly. This is a great invention, and would work with sporter rifles and ARs just as well.
NOTE: Obviously, this ring will increase the measured weight of your rifle. So, if you are competing in a registered match with weight restrictions, you have to ensure that your rifle still makes class weight limits with the ankle weight ring in place.

Today’s Saturday video showcase is a wheelgun extravaganza. We offer eight videos covering some of the most famous double-action revolvers in existence. Check out reviews of Colt, Smith & Wesson, Korth, Dan Wesson, Ruger, and other models, in a variety of chamberings, both centerfire and rimfire. We think every serious gun enthusiast should have at least two revolvers in his collection — one centerfire and one rimfire. This Editor owns a stainless, 10-shot .22 LR Smith & Wesson Model 617. It has probably shot more rounds than all my other pistols combined, and it is still performing flawlessly after 25 years.
Multiple Revolver Line-up: S&W, Colt, Ruger, Taurus, Dan Wesson, Chiappa, Charter Arms, Webley and More
This 12-minute video provides a quick introduction to eleven interesting wheelguns: Smith & Wesson Model 29 (00:22), Colt Python (1:22), Ruger GP100 (2:25), Taurus Model 66 (3:40), Smith & Wesson Model 686 (4:38), Charter Arms Bulldog (5:41), Chiappa Rhino (6:32), Webley Revolver (7:27), Dan Wesson 715 (8:21), H&R Model 929 (9:59), Taurus Judge Public Defender (10:52). NOTE: This video also includes a review of the Bersa .380 which is NOT a revolver, so the video title is a little misleading. There are 12 handguns, but only 11 revolvers.
Colt Python .357 Mag 1000-Round Test
How well do modern wheelguns hold up to extended use? This video provides an answer. Honest Outlaw’s testers put 1000 rounds through a new-generation Colt Python chambered for the legendary .357 Magnum round. The Python showed outstanding accuracy, and the tester praised the trigger. Testing was done indoors and outdoors, both rapid-fire and slow-fire. After a couple hundred rounds, the Python needed a thorough cleaning of cylinder and barrel, but otherwise the revolver performed really well.
Hickok45 Shoots the New Colt Anaconda in .44 Magnum
Hickok45 is a respected YouTube video reviewer. In this detailed 19.5-minute video, Hickok45 reviews and tests a new generation Colt Anaconda revolver, chambered for the powerful .44 Magnum cartridge. This Hickok45 review is one of the most popular wheelgun videos on YouTube, having logged over 1.4 million views in three years.
Colt King Cobra Target .22 LR Revolver
This TFB Showtime episode examines the new .22 LR rimfire Colt King Cobra Target. The King Cobra Target .22 LR features a 10-shot cylinder, and the same adjustable target sights as the .357 Magnum version.
At the NRA Annual Meetings in 2022, Colt Manufacturing introduced an impressive new rimfire revolver — the King Cobra Target .22 LR. Colt states: “From competition to plinking and small game hunting, this baby Cobra does it all and packs 10-rounds of .22 LR in its cylinder”. The King Cobra Target 22 LR is available with 4.25-inch and 6-inch barrel lengths, both with 1:16″ RH rifling twist. MSRP is $999.00.
The Massive Smith & Wesson 500 Magnum X-Frame
If bigger is better, then a Smith & Wesson 500 Magnum should be in your collection. This jumbo-size wheelgun shoots a huge 50-caliber cartridge, the .500 S&W Magnum. Even with compensator slots on the end of the barrel, the recoil is massive — enough so that we would NOT recommend this big revolver to novice shooters.
In 2003 the engineers at Smith & Wesson wanted to deliver maximum power for serious handgun hunters. The power they sought required an entirely new frame, the massive “X-Frame”. That became the basis for the new Model S&W 500, the most powerful production revolver in the world.
Colt vs. Smith & Wesson
Here’s a pretty informative video, with two qualified experts, Bill Wilson and Ken Hackathorn. This covers the basic differences between Smith & Wesson and Colt revolvers. This video explores the classic “Ford vs. Chevy debate” of the revolver world. Both S&W and the Colt revolvers have their die hard loyalists. In this episode, the Gun Guys weigh the merits of Bill’s Colt Shooting Master and Ken’s S&W Registered Magnum.
Korth Super Sport STX Revolver — $4,393.00 Wheelgun
Germany’s Korth Arms makes some of the best revolvers on the planet. Korth’s machining tolerances are second to none. The triggers are superb and the accuracy is excellent. At the 2022 IWA Outdoor Classics Expo, Korth featured a “badass” black heavy-barreled wheelgun, the Super Sport STX Revolver. This features a full-length scope rail and slab sides, for use in Bianchi Cup-type competitions.
Korth states: “In addition to the National Standard Super Sport STX, we present the weight-reduced ALX version. Both weapon types are equipped with a 4-position rear sight”. You’ll need serious bucks to buy a Korth Super Sport STX. Currently the 8-shot STX model in .357 Magnum sells for €4,077.00 Euros (about $4,393.00 U.S.). Below are a trio of blued Korth revolvers:
Smith & Wesson Model 648 in .22 WMR
We love Smith & Wesson rimfire revolvers. We have put thousands of rounds through S&W Model 617 revolvers, with 4″ and 6″ barrels. These stainless .22 LR handguns are accurate, superbly reliable, and they hold their value. In general we’ve found that Smith & Wesson rimfire revolvers may be less fussy with ammo, and more trouble-free than typical semi-auto rimfires. Bottom line, we feel that everyone should have an S&W rimfire wheelgun in their collection.
Along with its .22 LR wheelguns, S&W now offers another very impressive Rimfire Revolver option — the “revived” Model 648 in .22 WMR (Winchester Magnum Rimfire). This stainless Model 648 brings a more powerful cartridge to S&W rimfire revolver fans.

The last half-inch or so of your barrel is absolutely critical. Any damage (or abnormal wear) near the crown will cause a significant drop-off in accuracy. Here are ways you can check the end of your barrel, using a common Q-Tip.
Use Q-Tip for Barrel Inspection
To find out if you have a burr or damage to your crown, you can use an ordinary Q-tip cotton swab. Check the edges of the crown by pulling the Q-tip gently out past the edge of the crown. If you have a burr, it will “grab” the cotton and leave strands behind.
Larry Willis has another way to use a Q-Tip: “Here’s a neat trick that will surprise you with how well it works.” Just insert a Q-Tip into your barrel (like the picture below), and it will reflect enough light so that you can get a real good look at the last half inch of rifling and the crown of your barrel. In most cases you’ll find that this works much better than a flashlight. Larry tells us: “I’ve used this method about a jillion times. Q-Tips are handy to keep in your cleaning supplies anyway. This is a good way to judge approximately how well you are cleaning your barrel when you’re at the range. It’s also the best way to examine your barrel when you’re in the field.”
Sometimes you’ll get a barrel that doesn’t stabilize bullets the way you’d anticipate, based on the stated (or presumed) twist rate. A barrel might have 1:10″ stamped on the side but it is, in truth, a 1:10.5″ twist or even a 1:9.5″. Cut-rifled barrels, such as Kriegers and Bartleins, normally hold very true to the specified twist rate. With buttoned barrels, due to the nature of the rifling process, there’s a greater chance of a small variation in twist rate. And yes, factory barrels can be slightly out of spec as well.
After buying a new barrel, you should determine the true twist rate BEFORE you start load development. You don’t want to invest in a large supply of expensive bullets only to find that that won’t stabilize because your “8 twist” barrel is really a 1:8.5″. Sinclair International provides a simple procedure for determining the actual twist rate of your barrel.
Sinclair’s Simple Twist Rate Measurement Method
If are unsure of the twist rate of the barrel, you can measure it yourself in a couple of minutes. You need a good cleaning rod with a rotating handle and a jag with a fairly tight fitting patch. Utilize a rod guide if you are accessing the barrel through the breech or a muzzle guide if you are going to come in from the muzzle end. Make sure the rod rotates freely in the handle under load. Start the patch into the barrel for a few inches and then stop. Put a piece of tape at the back of the rod by the handle (like a flag) or mark the rod in some way. Measure how much of the rod is still protruding from the rod guide. You can either measure from the rod guide or muzzle guide back to the flag or to a spot on the handle.
Next, continue to push the rod in until the mark or tape flag has made one complete revolution. Then re-measure the amount of rod that is left sticking out of the barrel. Use the same reference marks as you did on the first measurement. Next, subtract this measurement from the first measurement. This number is the twist rate. For example, if the rod has 24 inches remaining at the start and 16 inches remain after making one revolution, you have 8 inches of travel, thus a 1:8″-twist barrel.
Determining Barrel Twist Rate Empirically
Twist rate is defined as the distance in inches of barrel that the rifling takes to make one complete revolution. An example would be a 1:10″ twist rate. A 1:10″ barrel has rifling that makes one complete revolution in 10 inches of barrel length. Rifle manufacturers usually publish twist rates for their standard rifle offerings and custom barrels are always ordered by caliber, contour, and twist rate. If you are having a custom barrel chambered you can ask the gunsmith to mark the barrel with the twist rate.

Competition Note:This past week the 2024 F-Class National Championships have been running in Lodi, Wisconsin with competition in both F-Open and F-TR divisions. F-TR is shot with a bipod and cartridge types are limited to .223 Rem (5.56 NATO) and .308 Win (7.62×51). The 2024 Mid-Range Championship ran August 10-13 while the 2024 Long-Range Championship ran August 14-17, concluding late yesterday. CLICK HERE for 2024 Championship Results.* We will soon have a full report on the 2024 event, but for today’s Sunday GunDay story, we look back at a Mid-Range winning F-TR rifle from a few years back.
Story based on Report by Bryan Blake, Blake Machine Company
Here’s the gold medal-winning .308 Win rifle of the 2020 F-TR National Mid-Range Champion, Andy Cyr. Arizona native Cyr won the F-TR Mid-Range Championship with an impressive score of 1761-72X out of a possible 1800 points. At this three-day Mid-Range event at Ben Avery in Phoenix, all 180 rounds were shot at 600 yards. Andrew delivered a convincing victory, winning by NINE points over runner-up James Crofts, a past national champion himself. We congratulate Andrew on his impressive win. And today’s Sunday GunDay feature examines the details of Andrew’s impressive .308 Win F-TR rifle.
Cyr Overcame Incredibly Tough Conditions at Ben Avery
After Day One of the Mid-Range Nationals, Andy was in 5th place. Andy made up some serious ground on the next two days despite winds that were well into the 20 MPH+ range. In fact, many experienced shooters took misses (not hitting the scoring ring) because the winds were so fierce. Interestingly, Andy’s 1761-72X score beat all but eight F-Open shooters.
Andrew Cyr’s .308 Win F-TR rifle during load development and accuracy testing.
F-TR Mid-Range Championship-Winning .308 Win Rifle Specifications:
Blake Barrel and Rifle 32″ .30 Caliber, 1:11″-twist barrel with custom specs
McMillan XIT Stock (lightened with ports on butt area)
Borden BRM Action
Kahles K1050 10-50x56mm Scope
Phoenix Bipod with F-Class Products lowering kit and skeleton legs
Andrew Cyr’s Championship-winning F-TR rifle was built by Phoenix-based Blake Barrel and Rifle (BBR) in 2018. Interestingly, this rifle was originally built for Andy’s daughter Jessica. The rifle was used by Andy a few months later. The rifle features a severely-lightened XIT stock with the grip smoothed out. Andy was actually the first customer of Blake Barrel and Rifle back in 2018. He has always been willing to try out new rifling profiles, twist rates, and barrel configurations as recommended by BBR.
Bryan Blake tells us: “Many customers demand exact specs and there is no way of changing their mind, even if it is factual-based. With Andy he was always willing to try new things, some things didn’t work well, but some things worked very well, just like the barrel used to win the Nationals.” Andy preferred a heavier barrel in the chamber area than most TR shooters. The shank diameter is 1.350″ rather than 1.250″. What this does is keep as much material around the chamber, which is the hottest area of the barrel. That way the barrel is less affected by heat over a string of fire, since the heat can be dissipated into a larger area.
Andy used a 32″ barrel, a length not commonly used in F-TR anymore. Most are running 30″ or even 28″ now. Many folks think a shorter barrel is more accurate so these competitors do not use a 32″ barrel. Well as you can see by his results, Andrew’s 32″ tube shot great. The extra length was NOT a handicap. We should remember that longer barrels can normally produce higher velocities than shorter barrels or deliver equivalent speeds with less pressure.
Many people also believe that a 1:9-10″ twist is needed to shoot 200-grain class bullets out of a .308 Win accurately. However, Andy took the advice of Blake Barrel and Rifle, and went with a 1:11″-twist Blake cut-rifled barrel. Many would say this twist is too slow, and some online calculators say a 1:11″-twist won’t fully stabilize 200-grain bullets. Obviously this is also not the case. Andy’s 11-twist and Berger 200-grain Hybrid bullets (NOT 200.20X bullets) work very well with this combination. NOTE: Andy uses an F-Class Products barrel tuner to tune his load. He will sometimes even alter tune between relays to compensate for changing barometric conditions.
Winning .308 Win Load — Lapua Palma Brass, VV N550, CCI 450s, Berger 200gr Hybrids
Andy Cyr took the Mid-Range title loading Vihtavuori N150 powder, CCI 450 primers, Berger 200gr Hybrids, and Lapua .308 Win Palma brass. Andy does not push his bullets very fast and finds a big accuracy node at the mid-2600 FPS range. He jumps his bullets .015″ off the lands. One thing Andy consistently does is test, test, test. He will test different powders, charge weights, seating depths nearly every time he is at the range. He will shoot a different load for each string to see what works best.
Profile of 2020 F-TR Mid-Range National Champion — Andrew Cyr
Father and Daughter Compete Together
Andy started shooting F-Class in 2012 to help him shoot better in the PRS series. He hoped to learn to read the wind better and get more experience in long-range shooting in general. After shooting F-Class he was hooked and found he enjoyed it more than PRS. Andy and his daughter Jessica have shot many state matches together, with both of them shooting F-TR. Jessica owned the Mid-Range 20-shot woman’s Aggregate record for years with a score of 200-11X. Interestingly Andy shot his very first clean at 1000 yards at the Nationals in Raton, NM in 2018 with a score of 200-11X also. This year Andy started using a spotting scope to help read mirage and it has helped him tremendously he reports.
The “Master” Beat the “High Masters”
Andy is currently classified in Mid-Range as a Master for F-Class, not yet High Master. Even after winning the F-Class Mid-Range Nationals, the most prestigious F-Class match of the year, he is still classified as a Master. Andy’s 1761-72X score works out to 97.8% of a perfect 1800. But the requirement for F-Class High Master is 98%. That just shows you how tough the conditions were at Ben Avery this year. But still the Master beat ALL the High Masters — if you look at the score sheet above, all the other Top 10 F-TR competitors were High Masters. Impressive. And we believe Andy is the first Arizona resident to ever win a national F-Class Championship in either F-Open or F-TR.
About Blake Barrel and Rifle Blake Barrel and Rifle (BBR) has been in business since 2018. BBR built the rifle that Brian Bowling used to win the 2019 F-Open National Championship. And now another ultra-accurate BBR-built rifle has won the 2020 F-TR Mid-Range Championship. Bryan Blake tells us that Blake Barrel and Rifle has recently upgraded BBR’s rifle barrel building equipment. There are advanced CNC lapping machines, CNC bore-honing machines, and all-new, proprietary rifling cutter designs that no one else in the barrel business uses.
Blake Barrel and Rifle produces cut-rifled, 6-groove barrels with a unique rifling profile no other barrel manufacturer is using. Blake barrels have an impressive winning record in recent major competitions — earning National Championships, plus many match wins and podium performances. Bryan Blake tells us that “The time and quality control spend on Blake barrels is second to none and the proof in the results.” For more information, visit Blakebarrel.com.
* We believe that Alan Kulcak won 2024 Long-Range F-Open while Randy Littleton won 2024 Long-Range F-TR Division. We believe Johnny Ingram is the 2024 Mid-Range Champ in F-Open and Tom Hubbard won the 2024 Mid-Range F-TR title.

You may have heard the phrase “blueprinting an action”, but do you know what that really means? Do you know what operations are done to an action during the blueprinting process? To help you understand, gunsmith Bill Marr of RifleShooter.com has created a helpful article showing a Rem 700 blueprinting job start to finish. This article spotlights how the procedures can be done with manual tools. Bill, who runs 782 Custom Gunworks Ltd., can also perform many of these operations with modern automated machinery. In fact, Bill has written a follow-up article on Truing a Rem 700 receiver with a Lathe.
Bill explains: “Blue-printing, or truing a rifle action, ensures the receiver face, threads, lugs, bolt lugs, and bolt face are square to the center line of the receiver.” In Bill’s informative article, Bill shows how he blueprints a Remington 700 short action receiver with .308 Win bolt face. He covers the following procedures step by step:
Action Disassembly
Ream Minor Diameter of Receiver Threads
Square the Receiver Lugs
Square the Face of the Receiver
Lap the Bolt Lugs
Square the Bolt Face
Bill employed a variety of tools from Brownells to complete the blueprinting job, including: Remington 700 Armorer’s Kit; Manson Receiver Accurizing Kit; Bolt Lapping Kit; Bolt Face Truing Tool; Manson Receiver Ring Facing Cutter; Multi-Vise with Jaw Pads; Silicone Carbide Abrasive; and Do-Drill Cutting Oil.
Highlights from the Rifleshooter.com article:
1. Chasing the Threads
We use the bushings to guide the receiver tap. This chases the threads and ensures they are square.
2. Truing the Receiver Face
Using the receiver facing tool, the front of the receiver is trued. The tool is placed over the tap and turned by hand. We used Do Drill to lubricate it.
3. Lapping the Lugs
The bolt lapping tool screws into the front of the action and applies rearward pressure on the bolt face. A little bit of lapping compound is placed on the front of the receiver lugs. The bolt handle is then raised and lowered repeatedly. Note — it is critical that we do not get any lapping compound on any other surfaces.
4. Truing the Bolt Face
On this bolt, the central part of the bolt face was low. After the truing operation, this Rem 700 bolt face is now completely square to the action.
IMPORTANT: Rifleshooter.com states: “This article highlights our project and is presented for information purposes only. This provides an overview of the process and should not be attempted without the guidance and supervision of an experienced gunsmith“.

Doan explains his design process: “A customer came to me wanting to know if I could build a silhouette stock that was 2 pounds or less. I used the Koa wood because it is a lower specific gravity than Walnut (which makes it lighter) and stronger. I was still able to use pillar bedding and keep the weight down. The fore-end could be shortened to reduce the weight even more.
Since the drops on a silhouette rifle are different than a prone rifle, I kept the pistol grip from the prone rifle which is comfortable and tried to come up with a higher cheek piece and more drop to the buttplate. All of this required lots of hand carving.”

Here is an insightful, fairly lengthy 1850-word article about the phenomenon we call mirage. The article explains how and why mirage appears, how it can best be monitored, and how mirage can indicate both wind velocity and direction. Top competitors follow the adage “Mirage is your friend”, because mirage can often be the most important indicator of wind variables — sometimes even more important than wind flags. “The mirage is more sensitive than the flags since it has less inertia and momentum”, wrote Desmond T. Burke, in his book, Canadian Bisley Shooting, an Art and a Science.
Well worth reading, this SSUSA article talks about the properties of mirage. Here is a sample:
“Mirage — can make all the difference between a shot landing squarely in the X-ring or being victimized by an undetected downrange breeze. The true power of mirage is found in its ability to betray the subtlest of breezes downrange. Its fluid movement… can not only provide wind direction, but speed as well.
Typically, the ability to detect mirage is maximized on warm, sunny and sultry days. Expect mirage to be most pronounced in mid-morning or early afternoon, although it ignores these rules with regularity[.]
Mirage is extremely powerful at identifying winds of less than 12 mph, particularly those gentle breezes subtle enough to not even bother moving the flags.
When there is no wind, or a gentle head or tail wind, mirage will appear to be ‘bubbling’ directly up from the ground. Many call this ‘boiling’, and it is probably the easiest of all to detect.
As a general rule of thumb, when wind speed increases, overall height of the waves produced by the mirage is reduced. Large peaks and valleys in the waves mean that particular mirage is being driven by a very slight breeze. Conversely, crest size is reduced with wind speed, making it harder and harder to detect, until the mirage disappears entirely at somewhere around 12 miles per hour. In other words, the taller mirage’s waves appear, the slower the breeze.”
Authored by the late Glen Zediker, this article covers barrel break-in procedures. It is particularly useful for dealing with factory barrels. We CAUTION readers — with outstanding, hand-lapped custom barrels from top barrel-makers, you may want to do very little break-in — clean sparingly and keep barrel heat low. Do NOT use abrasives aggressively. On our Krieger and Brux barrels, we simply wet-patched every 2-3 rounds for 20 rounds and the barrels shot superbly from the start with minimal fouling. But for factory barrels, a moderate break-in process may prove beneficial.
Zediker explains: “Lesser, lower-cost barrels are going to have more pronounced … imperfections within the bore[.] These imperfections are largely tool marks resulting from the drilling and rifling processes. And if it’s a semi-automatic, like an AR-15, there might be a burr where the gas port was drilled. The goal of break-in is to knock down these imperfections, thereby smoothing the interior surface.”
As one who has experienced a cartridge case-head blow-out with a 9mm pistol, this Editor is very conscious of the risks involved and the damage a blow-out can do to the pistol, to the magazine, and (worst of all) to the shooter. Even with new brass, the possibility of a case failure is always present. And even if the case remains intact, we’ve seen primer failures that create a dangerous jet back towards the pistol shooter. That’s why shooters should always employ protective eyewear whenever they shoot.
We love our wheelguns, but there’s no doubt that forcing cone damage can occur, particularly with hot loads and if your cylinder-to-barrel gap is excessive. This article explains how to inspect your revolvers, and how to mitigate the likelihood of forcing cone damage. The article also explains how to clean your revolvers properly. This is very important to avoid build-up of lead and powder residues.

Credit our buddy Joe Friedrich for this simple yet effective accessory for your benchrest rifle. Joe shoots a .22 LR benchrest rig with a barrel tuner. When he added weights to his tuner, he found his rifle no longer balanced well. He wanted to add some weight in the rear without drilling holes in the stock. He also wanted the weight to be removable, and easily placed on another rifle in his stable. He wanted a weight that could be moved from gun to gun as needed.

The last half-inch or so of your barrel is absolutely critical. Any damage (or abnormal wear) near the crown will cause a significant drop-off in accuracy. Here are ways you can check the end of your barrel, using a common Q-Tip.
Sometimes you’ll get a barrel that doesn’t stabilize bullets the way you’d anticipate, based on the stated (or presumed) twist rate. A barrel might have 1:10″ stamped on the side but it is, in truth, a 1:10.5″ twist or even a 1:9.5″. Cut-rifled barrels, such as Kriegers and Bartleins, normally hold very true to the specified twist rate. With buttoned barrels, due to the nature of the rifling process, there’s a greater chance of a small variation in twist rate. And yes, factory barrels can be slightly out of spec as well.
