Here is gunsmith Richard King, with his updated Martini Mark III smallbore rifle.
This is the kind of family-friendly, “feel-good” story we like. A few years back, Texan Richard King created a rimfire benchrest rifle using a classic Martini Mark III smallbore action. He fitted the gun with a new flat, wide forearm and a new buttstock, allowing the gun to sit steady on the bags and track smoothly. The narrow action was also fitted with a cantilevered top rail to hold a high-magnification scope.
Here is Vicki King, with Martini Mark III and her trophy.
But here’s the best part. A decade ago, back in 2014, Richard provided this updated classic to his wife Vicki, who proceeded to win a rimfire benchrest match (Vintage class) with the old Martini. Richard reports: “Here is my lovely wife with her High Overall Vintage trophy. That is a Martini Mark III that I re-stocked in walnut for 50-yard, .22-caliber benchrest matches. It’s great to have her shooting with me again.”
Bravo Richard — kudos to you AND to your lovely bride. It’s great to see a couple shooting together. It’s also great to see a classic rifle brought back to the winner’s circle with some inspired stock-work, new optics mount, and other smart upgrades. Old rifles never die… at least if they find their way to a great smith like Richard King.

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.

SEB Rests has come out with a new, more compact front joystick rest for rimfire and air rifle competition. Designed for benchrest rimfire and air rifle shooting, the new AR250 Rest takes its name from the perfect score of 250 in WRABF competition. Balancing mobility, performance, and cost, this rest features a rigid, extendable central post and two elevation adjustment systems for rapid and smooth height changes. Current price is $620 US dollars, a bargain compared to some other joystick rests.
The new AR250 provides a very stable shooting platform yet is still easily transportable. The versatile design makes it suitable for multiple rimfire and air rifle disciplines. The AR250 joystick travel is designed to be able to cover most target sizes from WRABF to NRA/ARA at 25-100 yards and 25-100 meters. Fitted with an adjustable counterweight system for smooth joystick action, the newly designed top plate secures the custom front bag firmly in place with minimal play. The AR250 rest is offered with three bag options: one 2 1⁄4″-wide bag, one 3″-wide bag, or both sizes.
SEB AR250 rest has very extensive height adjustment range to fit varying rifle styles and target heights.
Initial user reviews have been very positive. Here are comments from customers and testers:
— “I am delighted with the accuracy and smoothness of operation. Brilliant product.”
— “The rest is very compact and lightweight. I recommend for anyone who… has struggled shooting rimfire with oversize pedestals designed for centerfire benchrest.”
— “The joystick feels smooth and precise, and the counterweight makes aiming feel wonderful.”
— “The rest is very solid for as small that it is, and the construction is wonderful.”
— “It transports far easier than any of the rests I have tried so far.”
Included in the box are: AR250 rest and front bag(s), Joystick arm and adjustable counterweight, leveling screws, 3 rest feet with hard neoprene rubber bottoms, spare bolts/accessories, and user manual.

Top is a CZ 457 MTR; middle Anschutz with BR stock; bottom is Bergara B14R in DPT Chassis.
With the variety of rimfire disciplines, from cowboy action to Olympic three-position smallbore, there are countless different rimfire designs on the market — bolt guns, lever guns, single-shots, toggle-links and more. These may shoot the same ammo, but they certainly vary in looks and ergonomics. This is testimony to human creativity.
In our Shooters’ Forum, you’ll find a long-running thread showcasing rimfire rifles for plinking, hunting, 3P Target Shooting, Silhouette, Rimfire F-Class, NRL22 and more. Here are some of the notable recently-posted rifles in that Forum thread, with brief build/component details.
ARA Benchrest Rifle with Stiller Action, Shilen Ratchet Barrel
Forum member Peebles24 showcased his cool flame-paint-job .22 LR benchrest rifle against a scenic, snowy background (never too cold to shoot right?). “I had a new rifle built this past fall by Mark Penrod at Penrod Precision. Stiller 2500X action, Shilen ratchet barrel, Jewell trigger, McMillan stock, Harrell’s tuner, Sightron SIII 10-50×60mm glass. I’m shooting it off my Arnold Machine one-piece rest made locally by Cliff Arnold. I visited the Lapua Testing Center East and got a case of Midas+.” For ammo testing results, click photo at right.
In late April the gun competed in its first ARA benchrest match in Wabash, Indiana.
Beautiful MasterClass-Stocked Rifle for Rimfire F-Class
Here is a handsome rifle belonging to Forum member Redd. Set up for prone Rimfire F-Class-style competition, this rig features a Shilen Ratchet barrel with Erik Cortina Tuner fitted to a Stiller 2500X action. It boasts a beautiful MasterClass figured Walnut stock and rides on a SEB Joy-Pod bipod up front. The optic is a Nightforce 40x45mm Competition.
CZ 457 .22 Magnum Transformed with KRG Bravo Stock
Forum member JAS-AS purchased a .22 Magnum CZ which he revived as a training rig with a new stock. He posted: “I use a CZ457 in .22 Magnum mainly as a trainer — bipod and rear bag kind of stuff. It has evolved over the last year or so. Next change will be a Lilja barrel. This because it can shoot brilliantly (at times) but not consistently. And accuracy degrades as it gets minimally dirty. Also, it doesn’t like 40gr rounds — the groups open up to 1.5 MOA. It’s at its best with 30 and 35 grain rounds running at up to 2250 fps. I believe that to be a twist-rate issue.”
The “Before” photo shows the rifle “as purchased” with a Nikon Monarch 4-16x42mm mildot scope. The “After” image shows the CZ 457 as modified. JAS-AS notes: “I added a bunch of stuff: KRG Bravo stock, Vortex Strike Eagle 5-25x56mm FFP scope, new bipod and Precision Underground bag, trigger spring. With this setup I shoot at 100 yards+ exclusively.” Show at right is a 9-shot group with the rifle at 100 yards. Three-shot groups at 100 have been below half-MOA.
Savage Mark II Squirrel/Field Rifle
This Savage Mark II rifle isn’t fancy, but it has brought much satisfaction to its owner, Forum member “Ohio Varmint Shooter”. He posted: “Just a nice field gun. Less than $200 (without scope). Cheap wooden stock, thin pencil barrel. My squirrel/field gun. There is absolutely nothing special about this… except it’s lefthanded. It shoots fine, preferring CCI standard velocity rounds. I did splurge and put a more-than-needed scope on it. Most scopes with fixed parallax (in this category), have it fixed at 50 yards. I wanted variable parallax so I could set it at 35 yards. I don’t know if it really makes any difference, but I do try to go for accurate head shots. The scope is also a little overkill in magnification, but it does help with the head shots and my aging eyes.”
“As a youth in the 70s, I always dreamed of a left-handed bolt. So getting back into shooting/hunting about 8 years ago, I was delighted to discover this gun. Growing up I had a semi-auto 22, but being a lefty … it would spit powder on my face.” — Ohio Varmint Shooter
Tikka T1x Action in Eliseo Competition Machine Chassis
Here is Gary Eliseo’s personal Rimfire Match Target Rifle with Tikka T1x action. The T1x action is carried in Competition Machine Rimfire Chassis. Gary also posted some recent 100-yard groups, using SK rifle match ammo in this rifle. Gary runs Competition Machine LLC and produces the chassis system for this cool rig, along with outstanding Across-the-Course, High Power, and F-Class chassis systems for rimfire and centerfire rifles.
Vudoo Action Benchrest Rifle with Benchmark 3-Groove Barrel
Here is a classy benchrest rig belonging to Forum member FCJIM. It features a Vudoo LBRP action, Benchmark 3-groove barrel, Harrell’s Precision tuner, NightForce Benchrest scope, and McMillan Edge stock. The stock work was done by Doan Trevor, while FCJIM did the metal work himself, using a Nevius reamer. This rig likes to shoot ELEY Black and Lapua Midas+ ammo.
Last but not least, here is a “blast from the past”. This classic lever-action single shot is crafted by CPS Rifles (Paul Shuttleworth), a boutique gun-maker specializing in single-shot rifles, particularly reproductions of the Stevens 44 1/2. Note the richly-figured wood and the lovely color case-hardening on the receiver. There is a dual Set Trigger system. You pull one trigger through a relatively long stroke until it clicks. The the second trigger breaks the shot (and drops the hammer) with just a few ounces of pull weight. This rig, fitted with MPA Vernier-type tang sights, belongs to Forum member “Mills” from Texas.

What kind of accuracy do you think is possible from a rimfire benchrest rifle? If we said 0.44 MOA you might not be surprised, thinking this was at 50 yards. But how about 0.44 MOA accuracy at TWO HUNDRED yards. Now that’s impressive. Consider this — at 200 yards, a 10 mph crosswind will push that little 40gr bullet 15.3 inches. Here’s the story, which comes from the Land Down-Under, Australia.
A few seasons back, Australian John Lavaring shot a group at 200 yards that would make most centerfire shooters proud. The five-shot group, with all shots in the center 10-Ring, measured just 0.93 inches. That works out to 0.44 MOA at 200 — mighty impressive for a .22 LR. Recorded at a Rimfire Fly Shoot benchrest event in Canberra, Australia, this 200-yard target set two new Australian SSAA National records! John was using ELEY Tenex ammunition.
Congratulations to John Lavaring for a spectacular demonstration of how well a rimfire rig can shoot — even at 200 yards. We rarely shoot our .22 LR rifles past 50 meters. Maybe it’s time to start a Rimfire ELR series, with targets at 200 or even 300 yards. What do you think of the Rimfire ELR idea? Leave comments below.
Anschutz 54 Benchrest Rig
The rifle was a Anschutz model 54 Match in a custom benchrest stock. John’s record-setting rig features a barrel block, which you can see forward of the action. Scope is a Bausch & Lomb BR model. We don’t have the round count on Lavaring’s barrel, but good rimfire benchrest rifles can often get 10,000 rounds (or more) of accurate life.
Rimfire Ballistics at 200 Yards
Some folks may be wondering about .22 LR ballistics at 200 yards. Well, with a 25-yard zero, the 200-yard drop for John’s 40gr Tenex ammo is 54 inches, assuming 0.145 G1 BC and 1085 fps muzzle velocity per ELEY website. And at 200 yards, a 10 mph crosswind will push that little bullet 15.3 inches! We’re told the winds were pretty tricky when Lavary shot his record group. This makes his achievement all the more impressive — we have to admire John’s wind-reading ability.
This ELEY ammo has proven to be exceptionally accurate. Here is a short video showing TEN rounds of Tenex shot from a machine rest with target at 50 meters.

Take a good look at this black-stocked, rimfire benchrest rifle. This just might be the most sophisticated (and accurate) Ruger 10/22 on the planet. This 10/22 was originally acquired as a used “donor gun” for just $98.00. Then its owner Les (aka “Scasa” in our Forum) completely upgraded the rifle from stem to stern. He added a rear lug to the receiver, threaded the receiver, installed a new barrel, and upgraded the trigger. Then he crafted the handsome benchrest stock from wood. He even designed and crafted the barrel tuner AND built the sophisticated shooting rest himself.
Overall, Les imagines he has over 1000 hours of design, fabrication, and fitting in this project. But the hard work paid off — this one-of-a-kind Ruger 10/22 shoots tiny groups. Is this the most accurate 10/22 on the planet? Possibly. But without question, it is the most sophisticated, do-it-yourself Ruger 10/22 project gun ever created.
$98 Ruger 10/22 Transformed into Tack-Driving Bench Gun
Report from Les E. (aka “Scasa” in our Forum)
I long thought I’d someday put an upgraded Ruger 10/22 together but the big hold-up was the receiver. I really wanted a threaded barrel/receiver and a rear lug for two-point mounting. They do make a rear lug that attaches to the rear of some aftermarket receivers but it’s just a little tab that attaches to the back, not what I would call really solid. So one day while hanging out at the local gun store I saw a Ruger 10/22 on the used gun rack for just $98.00. I latched onto it and I had my donor gun. This was an early gun that had the two guide rails for the bolt, walnut stock, and metal (not plastic) furniture.
Finished 10/22 rifle with rifle stock, tuner, and aluminum shooting rest all built by Les.
I then began a complete transformation of the rifle. Little did I know that, by the end of the project, I would put in about 1000 hours of labor. There were several things I wanted to make quite different than Ruger’s original design. First was to add the rear lug. Then get rid of the trigger pins. I also threaded the barrel hole in the receiver to get rid of the wedge. I also wanted to fix the bolt release. Of course that all required a new stock too.
In this video, Les explains the major upgrades he did to the Ruger 10/22:
Interested in this rifle build? Talk about it in our Shooter’s Forum. Rifle owner/builder Les can answer your questions about this Ruger 10/22 in this Forum Thread.
The Ruger 10/22 receiver was threaded to accept a more traditional barrel installation. Below is a conventional 10/22 drop-in barrel. Note that normal barrel is NOT threaded at receiver end, but slides in and then is held in place with a “wedge” locking block.
I made a rear lug that attaches to the back of the Ruger receiver with four, 6-32 screws and glued with JB Weld and filed to match the receiver contour.
Shown above is the completed gun before stock painting. The stock is made from nine pieces of Poplar 1x2s, with lots of sanding and black satin paint. Above is a photo of the stock before painting. As you can see, the laminations were stacked vertically. The rifle sits on a one-piece shooting rest I also built.
Editor: Les designed and crafted this sophisticated shooting rest himself. That’s right — this is a DIY rest! Les told us: “I built the rest from scrap aluminum. The design came from looking at rimfire rests online. Probably the Pappas Rest was the greatest influence. That Pappas rest cost about $1100.00 at the time for a polished one. I have less than a hundred dollars in mine now, but I’ve got a couple WEEKS of work in it. I’ve made two of them, one for my rifles and one for my benchrest pistol. It’s a lot of work to sand and polish, but in the end you have a solid shooting platform. Keep it waxed to preserve the shine.”
Watch Les shoot his fully-transformed and upgraded Ruger 10/22 with rest he built:
Editor: In the above video Les shoots his fully-upgraded Ruger 10/22 from a sophisticated one-piece rest he built himself. You can see how well the rest handles his upgraded Ruger 10/22. Below are the two 5-shot groups shot at 25 yards with this rig in the video. Very impressive! The ammo used was Wolf Match Extra.
More Upgrades — Trigger Pins, Bolt Release and More…
The trigger pins were replaced with 10-32 socket head screws which required threaded bushings to be put in the left side of the receiver and access holes in the right side of the stock. Now the trigger group and bolt can be removed without taking the action out of the stock. This also pulls the receiver sides together reducing bolt clearance. The trigger is shimmed with a piece of shim stock so it can’t be too tight.
There are several “How-Tos” which cover conversion of the manual bolt release to an auto bolt release, but it still requires a little fiddling with the darn thing. So instead of having it pivot on a slot, I welded up the slot and now it’s just a hole. I also welded on some more length and put a little knurled knob on it. With those modifications, it now works perfect.
The trigger housing is factory Ruger acquired at a gun show 25 years ago with Volquartsen hammer and sear. The barrel is a Green Mountain blank turned, threaded, and with a Bentz chamber. I made the barrel tuner. The rifle is fitted with a BSA 36-power scope I bought for $125.00 from the AccurateShooter Forum classifieds. There may be another $250.00 or so in parts and accessories I bought.
Editor’s Commentary — This project started with an old, used $98.00 Ruger 10/22 rifle. Now the transformation is complete. It took Les countless hours, and lots of effort, but he is deservedly proud of the end result. The excellence of the upgraded 10/22 is matched by the sophisticated, unitized aluminum shooting rest Les built. Very impressive design and execution.
So How Does it Shoot? Very Nicely Indeed!
Les reports: “Above is a target with some 3-shot groups while playing with the tuner. Those groups were shot at 25 yards. I figure at that distance I’m testing what the gun will do, not how well I can read the wind, not well and its been really windy. If I can get one clean hole 5 shots I’m pretty happy.”
Les electro-etched the caliber on the barrel. Les told us: “The machine was easy to make and works really well. It’s just a pain getting stencils.”

This article was originally written by noted rimfire gunsmith Bill Myers. Sadly, Bill passed away in May 2010, but his legacy lives on. He pioneered many advancements in rimfire gunsmithing and Myers-built guns still win matches in benchrest competition.
Crafting competitive rimfire benchrest rifles is considered an art as much as a science. The smith must understand subtle, yet critical aspects of vibration control, barrel tuning, and rifle balance. In the United States, only a handful of gunsmiths consistently turn out rimfire BR rifles that consistently run at the front of the pack at major matches. Bill Myers was one of those master craftsmen. In this article Bill discussed the process of building a winning rimfire BR rig. He reveals some interesting secrets, including his procedures for testing bedding performance and his barrel indexing system. Bill’s methods obviously work, as the Suhl-actioned rifle featured here won a truckload of trophies in its very first match.
Building a Match-Winning Rimfire Benchrest Rig
by Bill Myers
In my opinion, a winning rimfire benchrest rifle is probably twice as difficult to build as a competitive centerfire rifle. The relatively slow .22 LR bullets stay in the barrel much longer than centerfire bullets. This means that vibration control is critical. Likewise bedding is critical. Bore finish and lapping are very important. The amount of bore taper or “choke” can have a huge effect on accuracy. Ignition is also very important and above all, rimfire BR rifles need a very stable stock that tracks perfectly. A rimfire that shoots great is a complete marriage of all components and of the shooter’s need to be aware of everything possible.
Click Photo to Zoom
The rifle featured in this article was built from scratch with attention to all the details that go into accuracy. The goal was to build a gun that could win from the get-go. This would be a “Spec Gun”, meaning a rifle that was personally tested and tuned by me for optimum performance before it went out to the customer.
The Suhl trigger is as good as it gets so no change was needed. It easily adjusts down to about 2 ounces.
Baer Stock in Bubinga Wood
There are many choices when you start to build a complete rifle. It has to shoot well and it has to catch ones eye, or it’s just another rifle on the line. I prefer wood stocks on rimfires for two reasons: they are very stable if the right wood is used and they have a certain traditional appeal to many shooters. I chose Bubinga wood for this particular gun because it is very stable and heavy, it has a very dense grain and a very pronounced figure with a natural red color. The Bubinga is a very forgiving wood to work with.
Gerry and Bruce Baer in Pennsylvania do all my stock blanks. I do all my own inletting and bedding. The blank weighed 4.5 pounds when it came off of Bruce Baer’s duplicator. This Bubinga wood is so hard that it did not need pillars, but I put them in anyway. I bed all my stocks with Loctite Steel Bed liquid and add filler to desired thickness. The final bedding is done with an aircraft tooling epoxy that does not deteriorate over time. The stock has an ebony butt plate and six (6) coats of automotive clear, polished to a “high buff” finish.
Suhl 150-1 Action Accurized and BN-Nickel Plated
I used a new, unfired Suhl 150-1 action. As explained in the sidebar below, the Suhl 150 actions were originally crafted in East Germany for position rifles. They have a very fast lock-time and come with an outstanding trigger. However, they need some work when adapted to a modern BR gun. The action needed to be accurized and threaded. I have a special tool that I use to accurize actions. It uses two sets of spiders for dialing-in the bolt raceway. After the bolt raceway is running true, one can thread and true up all bearing surfaces so that everything is in perfect alignment with the action raceway bore.
BN-Nitride Plating on Action
I decided to plate the action and all bolt parts with Boron Nitride nickel plating. I bough the BN Electroless Nickel Kit from Caswell Plating and did the job myself. I started by bead-blasting the action so that it would end up with a “satin” finish. The plating material is then applied in a tank. The Boron Nitride goes directly into the plating solution, but you need to use a pump to keep the solution agitated so the BN distributes evenly.
Once the action is completely ready (the metal must be perfectly prepped, with no contaminants), the process goes easily and can be completed in about half an hour. The end result is a very slick, low-friction finish, that is .0002″ (two ten-thousandths) thick and hard as glass. The Boron Nitride makes everything very smooth. After the plating job, the action was noticeably slicker than before.
The cone breech (photo below) permits the barrel to be INDEXED (rotated around bore axis) to any position on the clockface. You then test various rotation settings to find the best accuracy. The system does work. Some barrels shoot best in a particular rotational setting. E.g. with index mark at 3 O’clock vs. 12 O’clock.
Fitting and Chambering the Barrel
As for a barrel, I had two good choices: one Shilen 1:16″-twist, 4-groove ratchet and one Benchmark 1:16″-twist, 3-groove. Both barrels were very accurate and at the end, I decided to leave the Shilen on the rifle because I wanted to put the Benchmark on another Suhl I’ve set aside for myself. I chambered the barrel for Eley flat nose EPS. We’ve found the gun also shoots the new Lapua X-ACT ammo very well.
The barrel finished at 25″ long and features a tuner by the Harrell brothers of Salem, Virginia. I use a flat 90° crown–it’s the most accurate and its gives a good seal against the tuner. I also use a 45°, 12-flute cutter that leaves no burr when cutting the crown. This chamfer protects the crown when cleaning the barrel. There is no sharp edge for the brush or jag to hit on the return stroke. The barrel was headspaced at .043″ and I use a tapered reamer ground by Dave Kiff of Pacific Tool & Gauge in Oregon. The chamber leade area is lightly polished to remove reamer burrs. The breech end of the barrel is machined with a 1/2″ ball end mill to produce what I call a “Myers cone breech.” Technically, it has a sloping radius as you can see, rather than a straight-sided cone. Finishing the breech in this fashion facilitates indexing the barrel, as the barrel can be rotated to any position (on the clockface), without requiring new extractor cuts.
Barrel Indexing — Finding the “Sweet Spot”
When indexing a barrel, one rotates it to different clockface positions relative to the action. Imagine marking a barrel at TDC or 12 o’clock, and then rotating it so the mark is at 3 O’clock, 6 )’clock, 9 O’clock and so on. At each position one shoots groups to determine at which index setting best accuracy is achieved.*
I know that barrel indexing is controversial. I don’t want to get into a lengthy debate other than to say that I believe that careful and thorough testing can reveal a “preferred” index position for a good barrel. With the barrel set in that particular position relative to the action I believe the barrel can yield optimal performance.
I perform the indexing tests indoors at 50 yards. I use a rail-gun with floating action. The barrel is held in place with a clamping fixture similar to an Anschutz 2000-series action. Basically, two vertically-stacked metal blocks clamp around the barrel. I can index the barrel this way simply by unclamping the barrel blocks, rotating the barrel and then re-clamping the system. I have a special system so the action can stay in the same position, even as the barrel is rotated.
It takes time and effort to get solid indexing results. Normally I shoot at least 400 rounds of ammo in 3-4 indexing sessions. Shooting a handful of groups is not enough. You may think you’ve identified the best index position, but you need to shoot many more rounds to verify that. Also, in a very good barrel, the effects of indexing may be subtle, so it will take many groups to confirm the optimal position. In my experience, really good “hummer” barrels do not benefit as much from indexing as an “average” barrel.
Accuracy Testing with Both Barrels
I tested the rifle indoors at 50 yards at the Piney Hill Benchrest Club range. There was no finish on the stock, but it shot well in my one-piece rest with the Benchmark 16-twist, 3-groove barrel and no added weight on the tuner. I shot 30 rounds of Eley Match EPS Black Box (1064 fps) and had 25 Xs and five 10s on the IR 50/50 style target. Not too shabby for a new barrel with no special break-in.
When the Shilen barrel arrived, I installed it on the rifle. By this time the stock had been clear-coated and finished, and the action had been polished and plated. I shot the Shilen barrel outside since it was too hot in the building. The first target was a 250-19X with a new lot of Eley Match EPS Black Box (1054 fps). The gun shot well. My friend Tony Blosser asked to shoot the gun, and he drilled a 250-20X in a steady wind using the same Eley ammo. See target at right.
Advanced Procedures — Vibration Control and Tuner Position
Barrel Tuning Using 2-Way Electronic Indicators
Before competing with this rifle, I put it in a firing fixture I use to tune the barrel. I employ a pair of very expensive Swiss 2-way electronic min/max hold indicators. These measure both up movement and down movement of the barrel as the gun is fired. I can measure the actual vertical travel of the barrel at any position from the front of the receiver to the tuner. I can also tell how long the barrel vibrates, time-wise. Using this fixture I found that the Shilen barrel was very consistent in readings and seemed to work well with no additional weight on the tuner. No barrel ever stops vibrating completely — but this was close, showing less than .002″ of total movement.
Bedding and Vibration Control
I have found that measuring the actual movement of the barrel during firing tells me a lot about the quality of the bedding. I have learned that if I see very big movements (e.g. .010″ up and .005″ down), then there may be a problem with the bedding. I saw this kind of big swing on a rifle with bedding that had not cured properly.
Another pattern I watch for is uneven vertical movement. For example, if the barrel vibrates .008″ up but only .002″ down, that tells me the bedding has issues. As noted above, I look for minimal vibration travel (after the tuner is fitted and optimized), and I also want that travel to be relatively equal both up and down. Good rimfire gunsmiths agree that proper bedding has an important influence on vibration control and tuning. By measuring actual barrel movement during firing, we can, to an extent, quantify how well the bedding is working. At a minimum, we can see if there’s a serious bedding problem.
Trial by Fire — Shooting the Gun in Competition
After semi-gluing in the action, the rifle was shooting great. So, I decided to take it to the Maryland State Unlimited Championship to see if it was truly competitive — whether it could “run with the big dogs”. As it turns out, the Bubinga Suhl was more than just competitive. The rifle won three of the six cards and won the meters championship. In the photo below you can see all the trophies the gun won in its very first match. One of the other competitors in Maryland, dazzled (and perhaps a bit daunted) by the Bubinga Suhl’s stellar performance, told me: “Sell that gun Bill. Whatever you do, just get that darn rifle out of here.” Confident that this was a rifle capable of winning major matches, I packed up the rifle and shipped it to Dan Killough in Texas. Killough has shot some impressive scores with the gun.
Suhl Target Rifles — East Germany’s Legacy
Suhl 150 rifles were manufactured in former East Germany (GDR) by the Haenel firearms factory in the town of Suhl. This region has a long history in arms production. In 1751, Sauer & Sohn founded the first German arms factory in Suhl. Following WWII, Suhl 150s were produced for Communist Bloc marksmen, including East German Olympic shooters. Prior to German unification, the East German national shooting arena was located at Suhl and hosted many top-level competitions including the 1986 ISSF World Championships.

As a product of East Germany, the “mission” of the Suhl 150 was to rival the accuracy of the Anschütz, Walther and other premium match rifles built in the West. East German shooting teams wanted to finish on top of the podium, so they needed a rifle with superb inherent accuracy. The Suhl 150s have an outstanding trigger that can be adjusted down to about two ounces. The Suhl 150 action, like the Anschütz 54, boasts an extremely fast lock-time — an important factor in a position rifle. And Suhl barrels were legendary for accuracy.
Suhl 150 Benchrest Conversions
Many of the first used Suhl 150s that made it to America were converted to Benchrest rifles because the action/trigger/barrel combination was unbeatable for the price. Some of the barrels on these “surplus” Suhls were phenomenal — as good as any custom barrels available today. It was not unknown for a Suhl 150 barreled action, transplanted into a benchrest-style stock, to win BR matches with the original barrel. Today, however, most of the Suhl benchrest conversions end up with modern, American-made barrels. While some older Suhl barrels can “shoot with the best of ‘em”, new barrel designs optimized for use with tuners have an edge, at least in benchrest circles. That’s why builders such as Bill Myers swapped out the Suhl barrel with something like a Benchmark reverse-taper two-groove.
Today Suhl 150 rifles are very hard to find in North America. In 2006, a used Suhl 150, even without sights, might fetch $1200.00 or more. Then, in 2007 through early 2008, hundreds of Suhl match rifles were imported. This drove prices down, and those “in the know” snapped up complete Suhl 150s at prices ranging from $450 to $850 (see 2007 advert at right), depending on condition.
Many of these rifles were left “as built” and used successfully in prone competition. Others were converted into benchrest and silhouette rifles, “parted out” for the actions and triggers. If you were able to grab one of those imports at a good price–consider yourself lucky.
* Bill Myers actually created his own clamping rimfire action to facilitate barrel indexing. CLICK HERE for Myers Rimfire Action. To index the barrel, Myers simply loosened three clamping-bolts and rotated 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. With a threaded action, you might have to use shims to test different rotational positions, or otherwise re-set the shoulder with each change.

What kind of accuracy do you think is possible from a rimfire benchrest rifle? If we said 0.44 MOA you might not be surprised, thinking this was at 50 yards. But how about 0.44 MOA accuracy at TWO HUNDRED yards. Now that’s impressive. Consider this — at 200 yards, a 10 mph crosswind will push that little 40gr bullet 15.3 inches. Here’s the story, which comes from the Land Down-Under, Australia.
A couple seasons back, Australian John Lavaring shot a group at 200 yards that would make most centerfire shooters proud. The five-shot group, with all shots in the center 10-ring, measured just 0.93 inches. That works out to 0.44 MOA at 200 — mighty impressive for a .22 LR. Recorded at a Rimfire Fly Shoot benchrest event in Canberra, Australia, this 200-yard target set two new Australian SSAA National records! John was using ELEY Tenex ammunition.
Congratulations to John Lavaring for a spectacular demonstration of how well a rimfire rig can shoot — even at 200 yards. We rarely shoot our .22 LR rifles past 50 meters. Maybe it’s time to start a Rimfire ELR series, with targets at 200 or even 300 yards. What do you think of the Rimfire ELR idea? Leave comments below.
Anschutz 54 Benchrest Rig
The rifle was a Anschutz model 54 Match in a custom benchrest stock. John’s record-setting rig features a barrel block, which you can see forward of the action. Scope is a Bausch & Lomb BR model. We don’t have the round count on Lavaring’s barrel, but good rimfire benchrest rifles can often get 10,000 rounds (or more) of accurate life.
Rimfire Ballistics at 200 Yards
Some folks may be wondering about .22 LR ballistics at 200 yards. Well, with a 25-yard zero, the 200-yard drop for John’s 40gr Tenex ammo is 54 inches, assuming 0.145 G1 BC and 1085 fps muzzle velocity per ELEY website. And at 200 yards, a 10 mph crosswind will push that little bullet 15.3 inches! We’re told the winds were pretty tricky when Lavary shot his record group. This makes his achievement all the more impressive — we have to admire John’s wind-reading ability.
This ELEY ammo has proven to be exceptionally accurate. Here is a short video showing TEN rounds of Tenex shot from a machine rest with target at 50 meters.

Here is gunsmith Richard King, with his updated Martini Mark III smallbore rifle.
This is the kind of family-friendly, “feel-good” story we like. A few years back, Texan Richard King created a rimfire benchrest rifle using a classic Martini Mark III smallbore action. He fitted the gun with a new flat, wide forearm and a new buttstock, allowing the gun to sit steady on the bags and track smoothly. The narrow action was also fitted with a cantilevered top rail to hold a high-magnification scope.
Here is Vicki King, with Martini Mark III and her trophy.
But here’s the best part. Back in 2014, Richard provided this updated classic to his wife Vicki, who proceeded to win a rimfire benchrest match (Vintage class) with the old Martini. Richard reports: “Here is my lovely wife with her High Overall Vintage trophy. That is a Martini Mark III that I re-stocked in walnut for 50-yard, .22-caliber benchrest matches. It’s great to have her shooting with me again.”
Bravo Richard — kudos to you AND to your lovely bride. It’s great to see a couple shooting together. It’s also great to see a classic rifle brought back to the winner’s circle with some inspired stock-work, new optics mount, and other smart upgrades. Old rifles never die… at least if they find their way to a great smith like Richard King.

We have used NO-LEAD Cleaner in rimfire benchrest rifles similar to this modified Suhl 150-1. It helped restore accuracy with minimal brushing.
Made by the same folks that created Wipe-Out™, and Carb-Out™, the NO-LEAD Brushless Lead Remover™ really works. Honest. If you are an active rimfire shooter, or if you shoot cast lead-alloy bullets in centerfire rifles and pistols, you should try this product. We now use NO-LEAD in our rimfire benchrest rifles, and in some centerfire guns that receive a steady diet of soft-alloy cast bullets (90%+ lead). (With rimfire guns, you don’t need to use NO-LEAD very often — maybe every 300-400 rounds unless you have a real fouler of a barrel.)
If you’ve got stubborn lead fouling in a rimfire barrel, or on a pistol’s muzzle brake/compensator, you should definitely give this stuff a try. We don’t know how but it does soften lead deposits. The manufacturer says you don’t need brushes, but we found that a bit of brushing (after NO-LEAD application) can help remove more serious lead build-up.
Frankly we were surprised to find a lead remover that really works. We tried a half-dozen other lead “cleaners” that promised to dissolve lead and most of them, we discovered, are nearly useless. There’s a reason for that, as the lead alloys used in bullets don’t react to typical petrochemical-based solvents. It took the Wipe-Out chemists over five years to perfect a new water-based solution that really does dissolve lead.
NO-LEAD Cleaning Procedure — Read Carefully NO-LEAD Lead Remover is a clear, red gel that is easy to apply. Just swab it in your bore (or on muzzle brakes) with wet patches or bore mop and let it sit for a few minutes. (The manufacturer says you can leave the NO-LEAD for up to 20 minutes, but that long of a dwell time does not seem necessary with our rimfire barrels.) When it contacts lead it will start to foam and you’ll see that the NO-LEAD solvent turns a pastel pink when it dissolves lead. The pink comes from the formation of lead oxide. After the recommended dwell time, simply patch out the dissolved lead deposits (you can also use a nylon brush for stubborn lead build-up).
NOTE: After cleaning, it is very important that you get all the NO-LEAD out of your barrel, and neutralize it. We recommend following the application of NO-Lead with Wipe-out or Patch-Out to neutralize the NO-LEAD, clear the bore, and remove residual carbon and copper fouling. If you don’t have Wipe-Out or Patch-out, flush the barrel thoroughly with Rubbing Alcohol or even a solution of Dawn dish detergent — then re-oil the bore.
Be Sure to Neutralize NO-LEAD After Use
Remember that N0-LEAD is a strong, slightly acidic chemical that needs to be neutralized after use. If you leave it on a nice, blued barrel for too long, it can harm the bluing. NO-LEAD will remove all the surface oils from the barrel bore. For this reason it is recommended that you neutralize NO-LEAD with Wipe-Out, or Patch-Out, which both contain effective corrosion inhibitors. If you don’t have those products, once you’ve flushed the NO-LEAD with something like rubbing alcohol, then follow with a gun oil. Caution: A petroleum-based gun oil will NOT, by itself, neutralize NO-LEAD. You need to neutralize first, then apply the corrosion inhibitor (or do it all in one step with Wipe-Out or Patch-Out).
Where to Buy NO-LEAD Lead Remover
NO-LEAD Lead Remover costs $15.99 for an 8 oz. squeeze bottle with a flip-top spout. This product is sold directly by Sharp Shoot R Precision Products, www.Sharpshootr.com, or you can purchase NO-LEAD through many other online vendors. For more information, send an email via the Sharp Shoot-R Contact Form or or contact Sharp Shoot-R at (785) 883-4444. You can ask for Terry Paul, Sharp Shoot-R’s owner and the master chemist who developed the NO-LEAD formula.
It’s good to see an ammo-maker step up to help the shooting sports. ELEY Ltd. has recently made significant investments in .22LR rimfire benchrest and competition segments within the USA. ELEY has partnered with the American Rimfire Association (ARA) and Professional Shooting League (PSL) to help promote and expand rimfire benchrest shooting, one of the fastest growing .22 LR rimfire competition disciplines worldwide. The ARA and PSL competitions are leading rimfire benchrest organizations within the United States. ELEY’s financial and logistical support will help the ARA and PSL grow the ranks of rimfire benchrest shooters.
Here’s a record-setting rimfire benchrest rifle owned by our friend Joe Friedrich who competes in ARA matches, primarily using ELEY .22 LR Tenex ammo.
ARA was started in April 1998 by a group of .22 LR shooters who wanted an organization for competitive .22 LR benchrest competition. In 2010, ARA started to transition to what it has become today, with the unique goal of continuing the vision of the ARA founders by providing an honest competitive organization that is true to .22LR shooting.
PSL was founded as a benchrest organization for the true precision shooting professional. With the growth of rimfire benchrest, there was a need to have a professional organization to which shooters would be compensated for their hard work, training and competition success.

Among .22 LR rimfire disciplines, benchrest shooting represents the “pinnacle of precision” — the very highest level of accuracy is needed to succeed. As such, ELEY has identified the need to help expand this growing sport. “This support by ELEY will help us bring .22 LR benchrest to the forefront of shooting competitions,” says Dan Killough, Director of ARA & PSL. “The expansion of [rimfire] benchrest … gives shooters a platform to enjoy and participate in rimfire competition that previously may not have been available to them,” stated Mike Corkish, ELEY Director of North America Sales.

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.
Forum member JAS-AS purchased a .22 Magnum CZ which he revived as a training rig with a new stock. He posted: “I use a CZ457 in .22 Magnum mainly as a trainer — bipod and rear bag kind of stuff. It has evolved over the last year or so. Next change will be a Lilja barrel. This because it can shoot brilliantly (at times) but not consistently. And accuracy degrades as it gets minimally dirty. Also, it doesn’t like 40gr rounds — the groups open up to 1.5 MOA. It’s at its best with 30 and 35 grain rounds running at up to 2250 fps. I believe that to be a twist-rate issue.”
