Mr. Smith’s Tack-Driving Thumbhole Trio
What is it they say? “Can’t have too much of a good thing?” We’ll in the case of Sam Smith of Wisconsin, that goes for beautiful wood-stocked thumbhole rifles that shoot like the blazes. This week we feature a troika of thumbholes, all smithed and stocked by Richard Franklin of Richard’s Custom Rifles (Richard is now retired but still offers DVDs). Not content with a single caliber or twist, Sam commissioned three different chamberings and barrel twist rates.
First, in Fiddleback Walnut — a 6PPC Walking Varminter The most elegant of the three thumbholes is this handsome .261″-neck 6PPC. The blue-printed Rem 700 action is pillar-bedded in a highly-figured stock of laminated Curley Fiddleback Walnut, in Richard’s #004 pattern. Richard uses three sections of wood bonded together so the outside looks like a single piece of Walnut.
The lead photo at top, and the image at right show more details of this rifle. The grain really takes on a rich color in sunlight, with the Tiger-stripe figure showing brilliantly through the clearcoat. Believe it or not, Sam doesn’t even consider this one of his best-looking rifles. Sam tells us, “these three thumbhole stocks are not even close to the prettiest guns Richard has built for me–you should see the Maple ones he did for me–they are unbelievable.”
Sam tells us the gun’s 1:14″-twist Krieger barrel is a hummer — it regularly shoots one-holers at 100 yards. Sam has even logged some groups in the Zeros with the gun–awesome accuracy for a varmint rifle/Sam tells us that, using VV N133 and 58gr V-max bullets, this gun is absolutely deadly on prairie dogs out to 500 yards. (SEE: One-hole Sample Target.)
Rifle #2 — Cherry and Walnut Together in a 6mm Rem Improved
When more knock-down power or more distant targets are in order, Sam pulls out his 6mm Rem Improved 1:12″-twist thumbhole Varminter. Like the other two guns, this features a pillar-bedded Remington 700 action and Krieger barrel. While the 6mm AI’s #004 stock shares the same shape and form as the 6PPC above, it is much more colorful, employing a seven-layer laminate in Cherry and Walnut, covered with multiple coats of automotive clear-coat. One of Sam’s favorite varminters, this rifle sees more range use than his 6PPC because “the PPC is so accurate I want to keep the round count down.” That’s not to say the 6mm Improved is any slouch in the accuracy department. Using VV N160 and 75gr V-max bullets, the gun averages in the 2s and 3s. The best group to date was .189″ with the 87gr V-Max (See V-Max Target below). Chalk that up to another superbly accurate Krieger barrel combined with outstanding chambering work by Richard.

Rifle #3 — Fast-Twist 6.5-284 with Benchrest Forearm
Last but not least is Sam’s handsome 6.5-284 (below), also in a laminated Walnut and Cherry stock. The Krieger barrel is a Heavy Varmint contour, with an 8-twist and .290″ neck. This gun hasn’t been shot much yet, but during initial testing it grouped in the mid-threes with 53gr of H4831 and 142gr Sierra MKs. You’ll note the stock is a bit different than the other two guns–this is the #005 stock pattern, which boasts a 3″-wide, flat forearm. It is identical to the #004 from the recoil lug rearward. Sam tells us that the #005 tracks better than the #004, though he prefers the rounded forearm of the #004 for a walking varminter.
Sam’s all-time favorite stock pattern in Richard’s #007, a roll-over comb design with conventional wrist and Cooper-style Beavertail forearm. Sam has a similar Maple #007 that he says is “even nicer than the gun in the picture.”
Nice Wood? You Ain’t Seen Nothin’ Yet!
After this trio of thumbhole rifles, Sam commissioned two more rifles — a matched pair in 6mm BR Norma and 6PPC, done up in absolutely amazing 500 year-old Turkish Walnut, sourced from a one-of-a-kind 48″ diameter Burl. What does a piece of wood like this cost? Trust us, if you have to ask, you couldn’t possibly afford it. Let us just say these are some of the most spectacularly figured blanks ever shipped from Turkey and they are priced accordingly. Here’s a preview, taken right before Richard bonded the first stock together. The lower two pieces look lighter because of the flash angle but the upper section more accurately shows how all three pieces appear in natural light. “Wow” is right!
Richard Franklin is Now Retired in Montana
The last we heard, gunsmith Richard Franklin was enjoying his retirement years up in Montana. On RichardsCustomRifles.com Richard posted: “I built fine custom rifles and for many years. I was the first stock maker to laminate woods such high-grade walnut, fiddleback maple and other fancy woods. I designed my own ideas into my patterns and carved, finished, pillar bedded thousands of stocks on the rifles I built. My most popular stock pattern was my Model 11 thumbhole.
I love building rifles but my health has forced me to retire and to take time to smell the roses. I made many great videos on how to build rifles and have been selling them for many years. They are still in great demand.” CLICK HERE to check out Richard’s DVDs about rifle building and varmint hunting.

2. Practical Shooter’s Guide
Marcus Blanchard, $19.99 Paperback, $9.99 Kindle
Thinking of getting started in the Practical/Tactical shooting game? Looking for ways to be more stable when shooting from unconventional positions? Then you may want to read Marcus Blanchard’s Practical Shooter’s Guide (A How-To Approach for Unconventional Firing Positions and Training). Unlike almost every “how to shoot” book on the market, Blanchard’s work focuses on the shooting skills and positions you need to succeed in PRS matches and similar tactical competitions. Blanchard provides clear advice on shooting from barricades, from roof-tops, from steep angles. Blanchard says you need to train for these types of challenges: “I believe the largest factor in the improvement of the average shooter isn’t necessarily the gear; it’s the way the shooter approaches obstacles and how they properly train for them.”
3. Long Range Shooting Handbook
Ryan Cleckner, $19.85 Paperback, $9.99 Kindle
Ryan Cleckner’s Long Range Shooting Handbook is the best-selling modern book on practical rifle skills. A former U.S. Army sniper instructor, Cleckner is knowledgeable, and his text is well-organized and chock full of good information. You can view Sample Chapters on Amazon.com.
Ryan Cleckner’s highly-regarded Long Range Shooting Handbook is designed as an intro to important fundamental concepts such as MOA vs. Mils, External Ballistics, and Environmental Effects. Included are personal tips and advice based on Cleckner’s years of experience as a sniper instructor and special operations sniper.
The Long Range Shooting Handbook is divided into three main categories: What It Is/How It Works, Fundamentals, and How to Use It. “What It Is/How It Works” covers equipment, terminology, and basic principles. “Fundamentals” covers the theory of long range shooting. “How to Use It” gives practical advice on implementing what you’ve learned, so you can progress as a skilled, long range shooter. This book will benefit any long-range shooter, not just PRS/NRL competitors.
4. Official U.S. Army Sniper Training and Operations Manual
From U.S. Army Sources, $17.59 paperback.
This U.S. Army Sniper Training Manual is a very comprehensive resource, with over 450 pages of information in a large 8.5″x11″ format. NOTE: Unlike other editions on Amazon, this is NOT the basic, outdated FM 23-10. This is the completely-overhauled 450+ page edition (FM 3-22.10). Heavily illustrated, this is a very useful resource for tactical/practical precision shooter. Employed as the “textbook” for the U.S. Army Sniper School at Fort Benning, GA, this big manual explains ranging methods, rifle handling, optics selection and operation, and rifle maintenance.
There is also extensive discussion of ballistics, wind reading, and weather effects. Practical competitors will appreciate the discussions of moving targets, range estimation, and range safety procedures. One reviewer explains: “This book contains the distilled wisdom of the Sniper School’s instructors and expert marksmen, giving you over 450 pages of unique insight into the long range combat shooter’s art.”
Grizzly.com has a handy product that should prove very useful for readers who need to swap barrels. This CNC-Machined aluminum barrel vise can be used in your home workshop, or on the road. In the field the vise can be fitted to a block of wood which can then be temporarily clamped to a bench. Or, as you can see below, you can mount the vise to a trailer hitch for use during a match or varmint hunt. The barrel vise is currently ON SALE for just $38.95.
This vise was designed by a member of the U.S. Shooting Team for quickly changing barrels up to 1.5 inches in diameter. Made of T-6061 Aluminum, the top clamping part of the vise is spring loaded so you can hold the gun with one hand while tightening the two nuts with the other. Grizzly notes: “Sometimes the action and scope can even remain on the rifle stock while the barrel is changed out.”
Clamping Range: Secures 7/8″ to 1.5″ Diameter Barrels
Block Dimensions: 5″ x 2.5″ x 1.4″ (Upper); 7.5″ x 2.5″ x 1.1″ (Lower)
Bolt Diameter: 3/4″ | Mounting: Use 1/2″ Hex Bolts to secure
IMPORTANT: This vise was designed for 7/8″ to 1.5″-diameter barrels. It may not work correctly with barrel diameters outside that range, or with unusual barrel contours. Not recommended for fine, polished blued steel barrels unless you protect the barrel surface before clamping. For most situations, where practical, we would remove the barreled action from the stock before using the vise.

Serious riflemen know that Krieger makes outstanding centerfire barrels that hold world records and have won many National Championships. But did you know that Krieger makes great rimfire barrels too? Well, Krieger does make outstanding .22 LR rimfire match barrels that can deliver impressive accuracy.
Sniper’s Hide moderator “Padom” recently tested a variety of rimfire ammo types, employing five different barrels: Krieger, Bartlein, Benchmark, Lilja, and Green Mountain. He tested at both 50 yards and 100 yards. FULL Rimfire TEST REPORT HERE.
Reporting on the 50-yard test, Padom posted: “Had a virtually dead calm day today for 50-yard RimX testing (Keystone Accuracy RimX barreled action with 1:16″ Krieger 20″ barrel). A few infrequent 3 mph gusts but pretty dead [calm] and the target showed. This Krieger just barely edged out the Bartlein by 0.003″ with a 0.177″ 6×5 with SK Rifle Match. The 10×5 was 0.198″. The best lots of Center-X weren’t far behind either. This is the first Krieger rimfire [barrel] I’ve shot and it didn’t disappoint.”
Padom noted: “Winds were much calmer tonight than this morning so the 100-yard Krieger test was a success. Winds were pretty consistent [at] 3-5 mph.”
Test Results at 100 Yards
Padom then tested ammo at 100 yards, again using his Krieger rimfire barrel: “To recap, the Krieger shot the best 50-yard results of the barrels tested so far, just barely beating the Bartlein but it was so close you can call the 50-yard results equal (.005). Well the Krieger beat all the barrels tested to date at 100 yards by a pretty good margin with Center-X. The 10×5 was incredible as well at just barely over 0.6″ showing the results were very consistent. A second lot of Center-X was right there with the previous 100-yard 6×5 best results just barely over 0.6. The third lot of Center-X shot a respectable 0.75″ 6×5. This Krieger sure is shooting very nicely. I’m really looking forward to shooting it at 300 and 400 yards[.]”
Components Tested: 20″ Krieger M24 barrel, .22 LR Match Eachus chamber 0.046 headspace, Zermatt RimX Action, Bix’N Andy TacSport Pro 2-Stage Trigger, RimX 10rd magazine, XLR Envy Pro Folding Chassis, Athlon Cronus BTR 4.5-29x56mm MIL scope.
Shooting Set-up: 100 Yards Prone with Bipod and Rear Bag.
With the civil disorder, rioting, and looting happening in major U.S. cities, many Americans are getting very serious about armed self-defense. But if you own defensive firearms, you definitely need to train with them. Indoor ranges are most convenient for those who live near urban centers, where the biggest threats to public safety currently exist. This article talks about indoor firearms training and the proper procedures you should follow at indoor ranges.
This Video Covers Basic Gun Range Safety Rules and Etiquette
FIVE IMPORTANT SAFETY PROCEDURES for Indoor Ranges
1. Follow the Three Fundamental Rules for Safe Gun Handling
ALWAYS keep the gun pointed in a safe direction. ALWAYS keep your finger off the trigger until ready to shoot. ALWAYS keep the gun unloaded until ready to use.
2. Follow ALL Range Officer Instructions
ROs are the first and final authority on any range and their decisions are generally final. Arguing with a Range Officer may just get you thrown out.
3. Don’t Bother Others or Touch Their Guns
Respect other shooters’ privacy unless a safety issue arises. Do NOT engage other shooters to correct a perceived safety violation unless absolutely necessary – inform the RO instead. NEVER handle or touch another shooter’s firearm without their permission!
4. Know Your Range’s Rules
Review and understand any and all range rules and requirements/expectations. For example, what is the range’s maximum rate of fire? Are you allowed to collect your brass?
5. Know What To Do During a Cease Fire
IMMEDIATELY set down your firearm, pointed downrange, and STEP AWAY from the shooting booth (or bench). Range Officers do not want shooters trying to “secure/unload” their firearms in a cease fire situation — they want the shooters separated from their guns instantly.
BAD RANGE BEHAVIOR — Five Things NOT to Do at the Range
Here are the five worst behaviors we’ve seen at indoor ranges. These behaviors are both dangerous and inconsiderate. Any one of these behaviors can get you permanently banned from an indoor range.
1. Sweeping other individuals after loading a weapon behind the firing line is very bad. All your weapons should be empty until you reach your shooting station.
2. Turning the handgun sideways while trying to clear a malfunction or insert/remove a magazine. This will point the muzzle at a fellow shooter. Or, after shooting a gun, the shooter fails to clear the weapon and then places the gun somewhere near the shooting station with the muzzle in an unsafe position.
3. Reacting unpredictably when firing a high recoil handgun. We’ve seen people take a second shot by accident with the muzzle way off target.
4. Not obeying range commands — in particular continuing to shoot during called cease-fires.
5. Poorly aimed shooting that hits target frames or carriers, causing ricochets.
Double-Up on Hearing Protection When Shooting Indoors
When shooting indoors we recommend quality muffs with earplugs underneath, offering double protection. When inside an enclosed range, with other shooters blasting away right next to you, you really need effective hearing protection. But you also need to hear range commands and be able to communicate. That’s why we recommend electronic muffs with plugs underneath.
For pistol shooting, we like the latest Howard Leight Impact Pro Muffs. These offer an impressive 30 dB Noise Reduction Rating (NRR). In addition, these muffs are pretty comfortable and offer Headphone Functionality so you can connect to your smartphone, MP3 player, or other audio device. These muffs are a good value. They are currently offered for $39.50 on ALLMAX.
Summer Solstice 2020 was June 20th, and July’s nearly here. That means “peak heat” summer conditions. It’s vitally important to keep your ammo at “normal” temps during the hot summer months. Even if you use “temp-insensitive” powders, studies suggest that pressures can still rise dramatically when the entire cartridge gets hot, possibly because of primer heating. It’s smart to keep your loaded ammo in an insulated storage unit, possibly with a Blue Ice Cool Pak if you expect it to get quite hot. Don’t leave your ammo in the car or truck — temps can exceed 140° in a vehicle parked in the sun.
To learn more about how ambient temperature (and primer choice) affect pressures (and hence velocities) you should read the article Pressure Factors: How Temperature, Powder, and Primer Affect Pressure by Denton Bramwell. In that article, the author uses a pressure trace instrument to analyze how temperature affects ammo performance. Bramwell’s tests yielded some fascinating results.
For example, barrel temperature was a key factor: “Both barrel temperature and powder temperature are important variables, and they are not the same variable. If you fail to take barrel temperature into account while doing pressure testing, your test results will be very significantly affected. The effect of barrel temperature is around 204 PSI per F° for the Varget load. If you’re not controlling barrel temperature, you about as well might not bother controlling powder temperature, either. In the cases investigated, barrel temperature is a much stronger variable than powder temperature.”
This Editor had the personal experience of 6mmBR hand-loaded ammo that was allowed to sit in the hot sun for 45 minutes while steel targets were reset. The brass became quite warm to the touch, meaning the casings were well over 120° on the outside. When I then shot this ammo, the bullets impacted well high at 600 yards (compared to earlier in the day). Using a Magnetospeed, I then chron-tested the sun-heated ammo. The hot ammo’s velocity FPS had increased very significantly — all because I had left the ammo out in the hot sun uncovered for 3/4 of an hour.
Powder Heat Sensitivity Comparison Test
Our friend Cal Zant of the Precision Rifle Blog recently published a fascinating comparison test of four powders: Hodgdon H4350, Hodgdon Varget, IMR 4451, and IMR 4166. The first two are Hodgdon Extreme powders, while the latter two are part of IMR’s Enduron line of propellants.
The testers measured the velocity of the powders over a wide temperature range, from 25° F to 140° F. Hodgdon H4350 proved to be the most temp stable of the four powders tested.
NRA Cancels WSC and NRA Police Shooting Championships Due to COVID-19
No big money this year at the NRA World Shooting Championship — the event has been cancelled. And Likewise the NRA Police Shooting Championship will not take place in 2020. This is the Year of Pandemic, and two more major shooting events have fallen victim to COVID-19.
Yesterday the National Rifle Association (NRA) issued the following statement:
Due to the circumstances surrounding the COVID-19 pandemic and the many ensuing federal and state safety regulations and mandates, the NRA has made the difficult decision to cancel the NRA World Shooting Championship and the NRA National Police Shooting Championships. Both events were scheduled to be held in mid September 2020 in West Virginia and Mississippi respectively.
We share your disappointment that both these competitions that attract participants from across the globe had to be canceled. The NRA wishes everyone good health and the best of luck. Stay safe and healthy.
The WSC was a big deal. It attracted top multi-gun competitors such as Jerry Miculek, Dan Horner, Doug Koenig, and Bruce Piatt. The winner took home a fat check for $25,000. This unique 3-day multi-gun match tests competitors’ skills across twelve challenging stages involving nearly every major shooting discipline for rifles, shotguns, and pistols. This major match attracted both sponsored Pros and “regular Joes”. Shooters were split into two groups: a Professional Division for sponsored shooters, and the Amateur Division for non-sponsored competitors. All firearms, optics, and ammo were provided by match sponsors for both divisions.
This video shows features of past NRA World Shooting Championship
All Equipment Was Supplied at NRA World Shooting Championship
“What makes this event very unique, especially to a professional shooter, is all the equipment is supplied. You have to leave your ego at home and just try to adapt as best you can to the equipment that you have supplied.” — Jerry Miculek
WSC stages encompassed everything from trap to bullseye pistol to PRS-style precision rifle. There was even a cowboy action stage with Henry “Golden Boy” lever-action rifles.
CCRKAB Hopes Millions of New Gun Owners Can Aid Second Amendment Battle
First concern over the COVID-19 pandemic spurred a huge increase in gun purchases. And the civil unrest, rioting, and looting that followed the death of George Floyd caused countless citizens to seek armed self-protection. COVID-19 and the riots convinced millions of Americans to become gun owners for the first time. These citizens wanted to protect their families, homes, and businesses. The Citizens Committee for the Right to Keep and Bear Arms (CCRKBA.org) hopes that these new gun owners may aid the fight to preserve the Second Amendment and gun rights in the USA.
“Look at all of the new people who suddenly decided to exercise their Second Amendment rights to keep and bear arms”, observed CCRKBA Chairman Alan Gottlieb. “We’ve witnessed something that is nothing short of a sea change… about gun ownership. We’ve heard anecdotal reports from all over the country about people flocking to gun shops who had never before owned a firearm. Now that they are gun owners, we expect them to be very protective of their rights”.
March, April, and May 2020 saw record numbers of background checks, according to FBI data and information from industry sources. For example in April 2017, gun sales set an all-time record — up 71% from the pervious year.
Gottlieb added: “We welcome all of these new gun owners to the firearms community… many of them are minorities, especially black and female citizens … from all age groups. They can… gain a new understanding of our efforts to protect the one fundamental right that actually protects all of the other rights.”
“This new wave of gun owners could become a formidable force during this year’s election,” Gottlieb noted. “From now on, we expect millions of new gun owners to pay closer attention to candidates, and reject those who would trample on their Second Amendment rights. With legions of new gun owners ready to protect these newly-discovered rights, it could be a pretty scrappy election year…”
Do primer types make a significant difference in accuracy or vertical dispersion at long range? The answer is “maybe”. Here’s one anecdotal study that tracked vertical variance among six different primer types. The tester is a good shooter with a very accurate rifle — four of the six 4-shot groups were under 2″ at 500 yards. This test doesn’t settle the question, but does suggest that it may be worth trying a few different primer types with your match ammo.
Here is a very interesting test for the 6 BRA (6mmBR Ackley) cartridge. Forum member James Phillips, a talented long-range benchrest shooter, tested SIX different primer types from three different manufacturers. To help determine vertical dispersion, James set his target out at 500 yards. He then proceeded to shoot 4-shot groups, in order, with each primer type. Velocities were recorded with a chrono. The photo above shows the results. James says: “I’ll retest the best two for accuracy and consistency with 10 shots each”. CLICK HERE for full-screen target photo.
As you can see, ALL the groups are pretty impressive. The smallest groups, 1.253″, was shot with CCI 400 primers. Next best (and very close) was CCI BR4, at 1.275″ for four shots. The “flat line” winner was the Remington 7.5, at upper left. There was almost no vertical. If you are intrigued by this interesting primer test, you can join the discussion in this Primer Test FORUM THREAD.

CARTRIDGE: 6mmBR Ackley, aka 6 BRA. Parent case is 6mmBR Norma. The 6 BRA is fire-formed to create a 40-degree shoulder and less body taper. Capacity is increased, but the neck is longer than a 6mm Dasher. The capacity is enough to get to the 2950+ FPS accuracy node. Some shooters say the 6 BRA is more forgiving than the 6mm Dasher. The 6 BRA is certainly easier to fire-form.
TEST REPORT — Conditions, Shooting Method, Loading Method
Tester James Phillips posted this report in ourShooters’ Forum:
Conditions: The testing was done in the morning over flags. The flags never moved or even twitched. I had as perfect conditions as I could have asked for. It was overcast so no mirage and no wind. There were no other shooters, just me.
Test Procedure: Each shot was precisely shot at my pace and centered the best possible using my Nightforce 15-55X scope. I did not use the round-robin method. Each four-shot group with the same was shot at one time. Then I moved onto the next primer. Everything felt right for each and every shot fired today. Of course I could repeat the test tomorrow and it could be exact opposite of today’s test. We can chase this forever. But [soon] I’m going to test the BR4 and 400 primer… for best accuracy and consistency for 10 shots each.
How Rounds Were Loaded: Each load was weighed to one (1) kernel of powder. So I know that’s as good as I can weigh them. Each bullet seating force was within 1# on my 21st Century hydraulic arbor press.
Previous Initial Load Testing: All groups were shot with 31.1 grains of H4895. During initial load testing I settled in on the Sellier & Bellot primer to finalize everything as it showed more promise over the CCI 450 Magnum I also tried. I was actually surprised to have seen the higher ES and SD from that primer today along with the vertical shown. [Editor: Look carefully — one shot from the CCI 450 is right in the center black diamond, stretching the vertical. By contrast the Rem 7.5 had almost no vertical.]
Groups Shot at 500 Yards with 6 BRA
Velocity and NODE Considerations: I was about 5-6 FPS above what appeared to been my optimum velocity of 2943-2945 FPS, so I’ll test 5 shots of 31.0 and 5 of 31.1 and see what happens from there. I can only assume my velocities where higher due to the higher humidity and of course temps were 5 degrees warmer this morning as well. It wasn’t far off but I noticed it.
This post essentially puts twenty bucks in your pocket if you need a chronograph. You see the MagnetoSpeed Sporter Chrono typically costs around $179.00 from most vendors. But right now MidwayUSA is running a special — the true “shopping cart price” is $159.99. That’s $20.00 cheaper than Midway’s regular price, and $19.01 cheaper than the lowest price we found anywhere else. But this special “Shopping Cart Discount” may not last long, so you may want to act quickly. We confirmed Midway’s $159.99 price on the morning of June 28, 2019.
Strapped on your barrel, the MagnetoSpeed Sporter records velocities accurately without requiring any hardware to be placed downrange. Everything is self-contained at your shooting station, so you no longer have to waste time setting up tripods and aligning the bullet path through old-fashioned chrono skyscreens. For most shooters, the MagnetoSpeed Sporter is all they need — they don’t need to spend $380.00 for the Deluxe MagnetoSpeed V3 Model. Here’s a video review which compares the Sporter to the more expensive V3 chronograph.
The most elegant of the three thumbholes is this handsome .261″-neck 6PPC. The blue-printed Rem 700 action is pillar-bedded in a highly-figured stock of laminated Curley Fiddleback Walnut, in Richard’s #004 pattern. Richard uses three sections of wood bonded together so the outside looks like a single piece of Walnut.
