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.

Ever shot a straight-pull (aka toggle-link) action rifle? We like these action types, which were developed for Biathlon competitors who needed to shoot fast, but were not allowed to use semi-auto actions. The biathlon-style toggle action features a lever on the side of the action. Pull the lever back with your index figure to open the bolt, then push forward with your finger to close the bolt*. It’s fast and efficient. With some practice, you can cycle the action in a couple of seconds — nearly as fast as a semi-auto.
The Volquartsen Summit .22 LR rifle is based on a concept originally developed by Primary Weapons Systems. Designed for both competition shooting as well as small game hunting, this unique rifle features a straight-pull, toggle-style action with a Ruger 10/22 profile. That means you can run 10/22 magazines, swap into stocks inletted for the 10/22, and even use after-market 10/22 barrels. The CNC-machined receiver features an integral 20 MOA Picatinny Rail. The Magpul stock adjusts for length of pull. Weight is 5.8 pounds, so this is easy to carry in the field.
The Summit features a lightweight carbon fiber-wrapped barrel, threaded 1/2×28 at the muzzle to be suppressor-ready. One of our favorite features on this little rifle is the trigger — which has a light, crisp 1.75-lb pull weight. Watch the video above to see the Summit .22 LR in action. The tester, 22Plinkster, was impressed with the rifle’s ease of use and accuracy. The Summit delivered a 0.277″ group at 50 yards, shot from the bench.
Good Field Test of Summit Straight-Pull Rifle by Dustin Ellermann
Past Top Shot Champion Dustin Ellerman demonstrates the Summit’s impressive accuracy by hitting small candies at 50 yards (06:13 start/06:55 impact). In rapid-fire drills, Dustin also shows the ease and speed with which the Summit action can be cycled.
Summits Now Offered in .17 HMR and .22 WMR Also
Last Year Volquartsen announced it would be expanding the Summit series to include other rimfire cartridge chamberings. Volquartsen is now offering a Summit .17 HMR and Summit .22 WMR.
These new .17 HMR and .22 WMR offerings will be available in stainless steel and lightweight aluminum configurations, with various barrel and stock options. All configurations will feature a 2.25-pound trigger pull, 0 MOA integral Picatinny rail, and a 9-round magazine capacity. Both 1/2 x 28 threaded barrel and non-threaded barrel options will be available. READ Full Report.
* Biathlon shooters cycle their Fortner toggle actions even faster, using their THUMB to close the bolt. This allows them to get the index finger on to the trigger blade faster. The whole process takes maybe a second — as fast as you can say “snick-snick”. To use the thumb effectively, you need a stock with a more vertical pistol grip. The Magpul stock on the Summit moves your thumb a bit too far back to use comfortably to close the lever without shifting the hand.

Most folks would be very impressed with a centerfire rifle that can shoot a quarter-inch group at 100 yards. But to do that with a rimfire rifle, shooting little .22 LR cartridges, that’s quite an accomplishment. Today’s Sunday GunDay story spotlights a superbly accurate new .22 LR Benchrest gun belonging to Forum member Dave Way. This rimfire tack-driver was crafted by respected gunsmith Alex Wheeler of Wheeler Accuracy. Check out this five-shot group Dave shot once he had figured out his optimal tuner position. That is mighty impressive for a rimfire rifle!
A sub-quarter-MOA group at 100 yards is impressive for a centerfire rifle. But for a rimfire rifle, it is truly stunning. Check it out — this rifle hammers!
I tested three lots of Lapua Super Long Range today. This lot looked really good so I bought a case. It’s a blast shooting this rifle over wind flags. It’s amazing how little wind it takes to move the bullet at 100 yards. I was having to hold off today to finish up groups. That’s when it’s the most fun. — Dave Way
Dave posted in our Shooters’ Forum: “To say I was impressed with the quality of the action and the accuracy of the rifle would be an understatement. I shot five different lots of Lapua Midas, Lapua Long Range, and Lapua Super Long Range ammunition. At 50 yards all the groups were pretty tight. I was shooting in some wind, using flags. One lot seemed to stand out so I put a target at 100 yards and shot three rounds in it as aiming points. I shot three five shot groups with the last 15 rounds of that lot that I had with me. All three groups were under 1/2″ and they were getting tighter as I moved the tuner!”
Above are initial 100-yard, 5-shot groups Dave Way shot with his rifle, while experimenting with different tuner positions. The largest group (on left) was a 0.416″, while the smallest (on right) was 0.296″. The average of the three groups was a stellar 0.369″ (0.352 MOA).
Dave Way treasures this rifle and praised Alex Wheeler’s skills as a gunsmith: “I have never received a rifle from Alex that didn’t shoot incredibly well and this one is no exception. I’m just getting into the .22 world so I don’t know if this is good, great, or excellent accuracy but it seems pretty accurate to me.”
Lot Testing and Tuner Experimentation Pays Off
Here are some initial groups Dave Way shot during initial ammo testing. They are all under half-inch at 100 yards. That’s pretty impressive — but read on. When Dave optimized his tuner position and found a great lot of Lapua Super Long Range .22 LR ammo — his groups got even smaller. Dave notes: “They could have been better but I was just getting used to the trigger and everything.”
Here are a series of three-shot, 50-yard groups. You can see this rifle is quite consistent. This is with five different lots of Lapua .22 LR ammunition.

Three 50-Yard Groups, All Under 0.180″ — That’s Consistency!
With the right ammo, this rig is wicked accurate. Here are three groups shot at 50 yards one after another. Dave shot these three 5-shot groups consecutively while optimizing his tuner: “Working with tuner the last two trips to the range. [It was] very consistent and pretty tight at tuner setting 162. Here are three consecutive 50-yard groups (5 shots each).” The biggest group (at bottom) measured 0.175″ (0.334 MOA), while the smallest group (middle) was a stellar 0.154″ (0.294 MOA) — that’s mighty impressive!
Alex Wheeler Crafted His Own Superb Rimfire Rifle First
Gunsmith Alex Wheeler of Wheeler Accuracy has, over the years, concentrated on ultra-accurate mid-range and long-range centerfire benchrest rifles, along with some stellar long-range hunting rifles. But Alex has started to venture into rimfire shooting. Prior to building the Dave Way rimfire rifle featured here, Alex built a “sister rifle” for himself with similar components. That gun turned out so well that Dave asked Alex to build another. And, as you can see, Dave’s new Wheeler-built rimfire rifle turned out to be a true tack-driver.
Alex credits Dave’s shooting skills: “I don’t think its possible for anyone to send a rifle to Dave that doesn’t shoot. He just has a knack for it. I’m glad I got into the rimfire stuff. I don’t have any interest in rimfire competition but it’s taught me a lot about bench manners and I get a lot more trigger time. It’s a great tool to learn wind flags with as well. It should make me a better centerfire shooter. That was really why I built mine. I normally sell every gun I build eventually and Dave was going to get mine but I said you should start gathering parts, I think I’m keeping this one!”
Lapua Long Range and Super Long Range .22 LR Ammunition
Dave Way had great results with his Lapua .22 LR ammo. Lapua Long Range and Super Long Range ammunition comes from Finland, and is designed for the growing long-range rimfire disciplines with targets at 100-300 yards. This ammo delivers very low ES and SD numbers. Our friend F-Class John tested this ammo and confirmed it performs very well (SEE Test Video).
Capstone’s Marketing Director, Geoff Esterline, explains: “Each production lot of Lapua’s [LR and Super LR] are test-fired in 50-round groups for dispersion. The results determine whether it makes Super Long Range or Long Range packaging.”

Here’s a fun new discipline that will grow in years ahead — Smallbore F-Class with .22 LR rimfire rifles. Rest-supported prone rimfire matches have been held around the world for quite some time, but only a few years ago was the discipline officially codified in the NRA Smallbore Rulebook. And the first-ever Smallbore F-Class National Championship was held in July 2018 in conjunction with the Smallbore Nationals at Camp Wa-Ke’-De in Bristol, Indiana. The Nationals involved multiple days of prone shooting at 50 meters and 100 yards. For more information read Hap Rocketto’s Shooting Sports USA Smallbore F-Class Report.
Smallbore F-Class competitors may shoot F-TR style with a bipod, or use a front rest. In the above photo from the inaugural NRA National Championship you can see a shooter with SEB Coaxial Rest at top, with a competitor using a low-profile bipod at bottom. Note the extended handle used to adjust bipod elevation. This is not a coaxial joystick, but rather a long handle attached to the mariner wheel.
Smallbore F-Class — The Future Looks Bright
With the high cost of centerfire ammunition, and the limited number of 1000-yard (or even 600-yard) ranges, we can envision that Rimfire F-Class will become a popular event at ranges across the country. Clubs don’t even need benches — just a 100-yard target bay and flat ground for the shooters. You can start with an inexpensive rimfire rig and Harris bipod. Then work up from there. Here is a custom rimfire F-TR style rig that belongs to F-Class ace and past centerfire F-TR National Champion James Crofts.
Rimfire F-Class and Fun Prone Matches with Front Rest or Bipods
Rimfire F-Class offers the fun of centerfire shooting at a much lower cost. Shooting is done prone with either a front rest or a bipod. You can shoot a relatively inexpensive rifle such as a CZ 457 MTR, or a custom build that has the same design features, weight, and ergonomics as a full-size F-TR or F-Open rifle. The choice is yours. We like shooting smallbore F-Class, because you can find decent .22 LR ammo for just $0.20 per round. By contrast, you’ll probably spend at least $1.20 per round for F-Class centerfire ammo (counting bullet, powder, primer, and part of the brass cost).
Top-Tier Vudoo V22-S Target Rifle for Rimfire F-Class
Vudoo Gun Works now offers an impressive .22 LR Single Shot Target Rifle that should prove ideal for rimfire F-Class (Open division). It features the new V22-S single-shot action, McMillan stock, and Flavio Fare BR-VS trigger.
Rimfire F-Class in the Canary Islands
This video comes from the Canary Islands, part of Spain. The voice-over is in Spanish but there are English sub-titles. The host explains: “In this video we summarize the main characteristics of this [shooting sport] that is practiced at 50 meters, 100 meters, and 200 meters with your .22 LR. Learn how to prepare your rimfire carbine and learn how to score your own targets by following our simple explanations. In another video we will delve into shooting techniques, shooting accessories and field accessories.”
Here is another rimfire F-Class video from the Canary Islands. This shows how the sport can be done with a variety of rimfire rifle types, even including a .22 LR AR clone. Some shooters are using a wide-base bipod, others are using normal Harris-type bipods, while others are using a large, benchrest-style front rest.
Rimfire F-Class-Style Local Fun Match in Oregon
In this video, F-Class John shoots an F-Class-style local fun match in Oregon. He is using a .22 LR rimfire rifle that has a full-size stock very similar to his custom F-Open centerfire rifles. This allows him to easily switch from centerfire F-Class to rimfire prone shooting with front rest and rear bag. The local fun match rules are a little different than an official F-Class match, but the shooting skills required are the same. Shooting this kind of local rimfire match allows John to keep his F-Class skills at a high level at a fraction of the cost of shooting centerfire F-Open.
Rimfire F-Class in Russia
NOTE: This video was filmed in Russia. The dialog is in Russian (without English subtitles), but it is still interesting to watch. Shooting F-Class with .22 LR ammo has become popular in Russia and other parts of Europe. You can have fun on a relatively short (200m) range with low-cost ammo.
Smallbore F-Class Course of Fire
The Smallbore F-Class Nationals was completed on paper targets at 50 yards and 100 yards. According to Shooting Sports USA: “The tournament ran during the any sight and metric phases of the 2018 NRA National Smallbore Rifle Championships, featuring a daily course of fire which mirrored the sling shooters, 40 shots at 50 meters on the A-50 target, a Metric Dewar, followed by 40 shots at 100 yards on the A-33 target. Although the international targets were shot throughout, the first two days were titled ‘conventional’ and the last two ‘metric’.”
The specifics of the match such as rifle requirements, rests, and sights may be found in the Provisional Smallbore Rifle F-Class Rules (Section 23), found on page 65 of the current NRA Smallbore Rifle rulebook. Any rules not covered in Section 23 will [reference] the normal rules of Sections 1 through 22.

Do you compete in rimfire benchrest, silhouette, or NRL22 matches? Then you’ll want to check out the Shooting Sports USA .22 LR Ammo Roundup on the SSUSA.org website. That article covers .22 LR ammunition from Lapua, ELEY, SK, RWS, Norma, Wolf, and Aquila. Notably there’s a detailed discussion of Lapua’s new Long Range and Super Long Range ammo. In addition, SSUSA confirms that SK ammo (made in Germany by Nammo, parent of Lapua) and Wolf Match Target ammo (made by ELEY) both offer quite good performance for a moderate price.
The article notes that there is a much wider range of .22 LR ammo types available now than a few years ago. It’s not just a choice between cheap products and high-end match ammo. As SSUSA explains: “It used to be that .22 LR was either quite expensive match grade ammo, or it was cheap plinking or hunting ammo. Today, competitors have choices in grades of .22 LR match ammunition to suit their pocketbook or firearms.” We’ve seen good results with relatively inexpensive Norma Tac-22, and the SSUSA article says that SK performs well above its price level.
Seven Brands of .22 LR MATCH AMMUNITION
Lapua Super Long Range and Long Range .22 LR
Lapua Super Long Range and Long Range ammunition comes from Finland, and is designed for the growing long-range rimfire disciplines with targets at 100-300 yards. Lapua says this ammo delivers very low ES and SD numbers. Our friend F-Class John has tested this ammo and confirmed it performs very well (SEE video above). “Each production lot of Lapua’s new rimfire products are test-fired in 50-round groups for dispersion”, Capstone’s Marketing Director, Geoff Esterline, said. “The results determine whether it makes Super Long Range or Long Range packaging.”
ELEY .22 LR Ammunition
ELEY has long been a top choice for .22 LR competition — both position shooting and benchrest. ELEY now offers 11 different varieties of .22 LR match ammunition, ranging in price from $7 (Benchrest Outlaw) to $20 (ELEY Tenex). If you compete in the rimfire benchrest, you should definitely try some ELEY ammo.
SK .22 LR Ammunition
Numerous .22 LR ammunition types are offered by SK, suitable for a variety of disciplines — from NRL22 to Biathlon. Generally cheaper than ELEY Match ammo, SK offers good “bang for the buck”. F-Class John says it performs great considering the price. The SSUSA article notes that: “German manufacturer SK has eight match-grade .22 LR offerings, including two for pistols, one for semi-automatic rifles, and one for frigid, wintertime conditions.”
RWS .22 LR Ammunition
Sometimes hard to locate at vendors in the USA, RWS is popular among European competition shooters. The top-tier RWS ammo is a choice of many competitive shooters. RWS currently offers nine Premium Line .22 LR varieties and three Professional Line offerings. The SSUSA tester noted that RWS Rifle Match ammo shot great in his Bergara BMR, shooting one-ragged-hole groups at 50 yards and about one MOA at 100 yards. That’s great performance for $10/box ammo.
Norma .22 LR Ammunition
Norma recently introduced XTREME LR-22, a new type of competition rimfire ammo with a radical new bullet. This unique, patented bullet design has a special base with a cone (see diagram). Norma claims that this “rocket tail” design reduces drag by creating less negative pressure at the back end of the bullet. It will be interesting to see how this new bullet design works in rimfire ELR competition.
Wolf .22 LR Ammunition
SSUSA says that Wolf Match Target is a top performer in the under-$10 per box category. This is because, according to SSUSA: “It is manufactured by ELEY in England (and loaded with Vihtavuori powder) and re-branded, if online information is correct.” Wolf Match Target is available from Target Sports USA for $74.99 per thousand ($0.15 per round).
Aguila .22 LR Ammunition
Made in Mexico, Aguila .22 LR rimfire ammo is the bargain item among the seven ammo-makers featured by SSUSA. It is widely available at very affordable prices.
We wouldn’t choose Aguila for a benchrest or three-position match, but it could be more than adequate for a local NRL-22 match or a steel-target competition at relatively short range. Aguila .22 LR ammunition starts at under $3.00 per box. And right now Midsouth offers a 2000-round Case of Aguila for just $114.99. That works out to just $2.87/box or six cents per round.

In 2019 CCI introduced a new type of .22 LR rimfire ammunition. CCI’s innovative Clean-22 Ammo features polymer-coated bullets. This is actually a pretty important development. The bullet coating on CCI’s Clean-22 ammo provides three main benefits:
1. Copper fouling in the barrel is greatly reduced.
2. Lead fouling in the barrel is greatly reduced.
3. Lead build-up in suppressors is reduced by 60-80%.
CCI has produced four versions of Clean-22 rimfire ammunition: Hyper Velocity (#954CC, 31gr, 1550 FPS MV), High Velocity (#944CC, 40gr, 1235 FPS MV), Subsonic (#934CC, 40gr, 1070 FPS MV), and Suppressor (#980CC, 45gr, 1000 FPS). These all feature lead bullets with polymer coatings. The Hyper Velocity ammo has purple-coated bullets, High Velocity ammo has red-coated bullets, Subsonic has blue-coated bullets, and the Suppressor version has black-coasted bullets. There was also a special 400rd Christmas pack of Clean-22 Hi-Vel ammo with Red and GREEN coated bullets, item #946XMAS.
Clean-22 Ammo with Polymer-Coated Bullets
Clean-22 uses an exclusive polymer bullet coating to greatly reduce copper and lead fouling in the barrel without leaving a residue. It also cuts lead buildup in suppressors 60 to 80 percent. Both the Sub-Sonic and High Velocity loads feature a 40-grain round nose lead bullet with geometry that’s been optimized for accuracy. With dependable CCI priming and consistent propellant, Clean-22 provides reliable cycling through semi-automatics and all 22 LR firearms.
SIG Sauer has a new .22 LR rimfire handgun — the P322-COMP pistol. Designed for speed, accuracy, and flat shooting (low muzzle flip), this new rimfire pistol from SIG SAUER is ready for competition right out of the box. It comes with a red dot optic, barrel-mounted compensator, slide-mounted racker, good trigger, and high-capacity (20- and 25-rd) magazines. READ P322 Manual.
We think this would be a good choice for fun action pistol matches. One YouTube viewer noted: “I applaud SIG… basically [the P322-COMP is] the first RFPO (Rimfire Pistol Open) factory option for Steel Challenge. Every other gun on the market you have to buy the optic, thumb rest, and compensator.”
SIG P322-COMP — Components and Features Video
NOTE: This 44-second video from SIG Sauer has detailed illustrations of all components with 3D rotation of the pistol so you can see it from all angles.
SIG Sauer states: “The P322-COMP ships with a factory-installed ROMEO Zero ELITE Red Dot optic for fast target acquisition, is designed with a slide mounted racker and sport takedown lever as value-added fun features. It has a barrel-mounted compensator to reduce muzzle rise making the P322-COMP a fast, fun, and [flat-shooting pistol].
The SIG SAUER P322-COMP is a competition-ready .22 LR rimfire pistol with class-leading 25+1-round and 20+1-round capacity. It has a threaded barrel equipped with a 2-port compensator and comes with a factory-installed ROMEO Zero Elite Red Dot Optic. The polymer grip features an extended magazine catch, adjustable trigger shoe, sport takedown lever, 1913 rail, and integrated magwell. The Single Action Only hammer-fired action on the P322-COMP is completely enclosed in a two-tone competition alloy slide with a high viz fiber-optic front sight, plus front, rear, and top cocking serrations. The ambidextrous, slide-mounted racker ensures easy slide manipulation. The pistol ships with (1) 20-round magazine and (1) 25-round magazine.

While Accurateshooter.com concentrates on high-accuracy rifles, we know that many of our readers enjoy handguns. We are often asked “What is your favorite handgun — Glock? HK? SIG Sauer?” The answer to that question may be surprising. This Editor’s favorite handgun, at least the one that gets shot most often, is a rimfire revolver — that’s right, a wheelgun.
This Editor’s first really accurate handgun was a .22 LR Smith & Wesson Model 617 that could easily stack ten shots in a dime at 10 yards. It remains my favorite and most-used handgun. What can we say about the Model 617? The single-action trigger pull is superb, and the accuracy surpasses most any semi-auto rimfire pistol, except for a few, very expensive target pistols. We like the 6″ version for the longer sight radius, but the 4″-barrel 617 is also very accurate, and it balances better.
S&W Model 617 now has a 10-round cylinder, but early models were six-shooters.
We recommend that new pistol shooters start off with a .22 LR rimfire handgun. The .22 LR cartridge is accurate but has very low recoil, less “bark” than a centerfire, and very little smoke and muzzle flash. New shooters won’t have to fight muzzle flip, and won’t develop a flinch from the sharp recoil and muzzle blast common to larger calibers. With the .22 LR, the trainee can focus on sight alignment, breathing, and trigger pull.

Here are three video reviews of the Smith & Wesson Model 617, both 4″-barrel and 6″-barrel versions. All three videos demonstrate the 617’s great accuracy. The reviewers concede that this handgun is pretty expensive, but all agree that the Model 617 will last a lifetime, and hold its value.

Colt King Cobra Target .22 LR Revolver
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.
This TFB Showtime episode examines the .22 LR rimfire Colt King Cobra Target. The King Cobra Target 22 LR boasts a 10-shot cylinder, and the same adjustable target sights as the .357 Magnum version.
The King Cobra Target 22 LR features USA-forged stainless steel construction. Designed and crafted for outstanding accuracy, new King Cobra Target 22 LR features a one-piece barrel/shroud with fiber optic front sight. The cylinder holds ten (10) rounds. The frame is fitted with an adjustable target rear sight and Hogue overmolded rubber grips.
Ruger GP100 .22 LR 10-Shot Revolver
Ruger offers a big stainless .22 LR wheelgun to compete with the S&W Model 617. This rimfire wheelgun is based on Ruger’s trusted GP100 platform. The Ruger GP100 chambered in .22 LR looks to be a good firearm — strong, versatile, and intelligently engineered. In the video above, the late Jeff Quinn of Gunblast.com tests the Ruger revolver and gives it high marks: “It’s a good hefty gun [42.6 oz.], but not overly large or heavy for a good trail gun. It’s just a really nice, well-made revolver from Sturm Ruger.” The gun Jeff tested had a 3.7-lb SA trigger pull and a 9.8-lb DA pull.
The .22 LR GP100 features a windage and elevation adjustable rear sight with a white outline, a light-gathering fiber optic front sight and the original full-size GP100 rubber grips with hardwood inserts. With all stainless-steel construction, the rimfire GP100 is easy to maintain. Just keep the cylinder chambers and barrel clean and this gun should run forever.
This Review of the .22 LR GP100 by Hickok45 has over 6.8 Million Views:
The 10-shot Ruger GP100 in .22 LR is a durable, well-engineered wheelgun. Ruger’s engineers optimized the GP100’s innards to deliver a smooth double-action pull: “The new GP100 has an improved fire-control system that uses a lighter mainspring than previous Ruger double-action .22 LR revolvers … we’ve done a lot of development on the firing pin location and geometries so that we’re able to put a lighter trigger pull in this gun than you would find in other .22 LR [handguns]. We’ve got a half-underlug barrel, and it’s a smaller diameter so the gun balances real well. We’ve added a narrow-spur hammer and a smooth trigger.”
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.

At the NRA Annual Meetings last year (2022), Colt’s 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 King Cobra Target 22 LR features USA-forged stainless steel construction. Designed and crafted for outstanding accuracy, new King Cobra Target 22 LR features a one-piece barrel/shroud with fiber optic front sight. The cylinder holds ten (10) rounds. The frame is fitted with an adjustable target rear sight and Hogue overmolded rubber grips.
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.
Last May, Justin Baldini, Colt’s VP of Product Strategy stated: “We are very excited to debut this new Baby Snake to our customers[.] Shooting .22 LR is such an important part of shooting sports. It’s where we come to learn as a beginner; and where we return as seasoned shooters to cost-effectively enjoy more time at the range. We’re confident that new and old Colt fans will love what we’ve done with the new King Cobra 22 LR.”
All-American built, the King Cobra Target 22 LR was designed and made to be shot — a lot! It should deliver exceptional accuracy and good reliability. Expect to see these revolvers at formal and informal rimfire competitions at gun clubs around the nation.

Commentary: We applaud Colt for introducing this new .22 LR wheelgun. Rimfire revolvers are great. This Editor owns a Smith & Wesson Model 617 ten-shot rimfire revolver that has easily fired more rounds than all his other handguns combined. A .22 LR revolver is great for training and fun for plinking. Like the Model 617, this new Colt .22 LR wheelgun offers minimal recoil, great reliability, a nice sight radius, and affordable shooting. In addition, if you shoot single-action slow-fire, the trigger pull is light and crisp — better than the vast majority of semi-auto pistols. We think this new “Baby Snake” will be a great addition to any shooter’s collection.

The Civilian Marksmanship Program (CMP) has approved new divisions for adults and juniors that will be implemented at the 2024 CMP Bianchi Cup and added to the CMP’s Action Pistol Program. The major development is the approval of a new Rimfire Division. That’s a very big deal that makes the Cup competition much more affordable. We applaud this move by the CMP.
Along with the new Rimfire Division, the CMP will add new “Provisional Divisions” for Production and Production Optics. CLICK HERE to learn more about the new Bianchi Cup Rimfire and Provisional Divisions.
The 2024 CMP Bianchi Cup is set for May 21-24, 2024 at the Green Valley Rifle & Pistol Club in Hallsville, Missouri. This prestigious 40-year-old action pistol match includes four featured events: Practical, Barricade, Falling Plate, and Moving Target. Hundreds of competitors from around the world compete in the event each year.
New Competition Classes: Rimfire, Provisional Production and Production Optics
In 2024, Bianchi Cup participation should increase significantly as the CMP is introducing new competition classes. Awards will be presented for all three new divisions: Rimfire, Production, Production Optics. The biggest change is the inclusion of a Rimfire Division. This division will encompass the same basic rules for each of the current setups — Open, Production/Production Optics, Metallic and Revolver.
The Rimfire Division is designed to encourage participation from juniors not shooting centerfire pistols as well as adults who want to warm up for the Bianchi Cup in a less expensive manner.
Provisional Divisions for Production and Production Optics will also be added to action pistol (with current Production and Production Optics divisions remaining unchanged). The rules for the new Provisional Divisions will be derived form USPSA rules.
Competitors will be divided into their divisions — Metallic, Production, Open, Production Optic, Provisional Production, Provisional Production Optic, or .22 Rimfire — per current CMP Action Pistol Rules.
Handguns for Bianchi Cup’s New Rimfire Division
If you’re looking for a reasonably-priced semi-auto .22 LR pistol for the new Rimfire Division, we recommend the Browning Buck Mark series. Buck Marks are accurate and very reliable. This rimfire pistol is available in a variety of models starting at under $370.00. A good Buck Mark will serve you for a lifetime.
For Rimfire Revolver competition we recommend the 10-shot Smith & Wesson 617 and the relatively new 10-shot Colt King Cobra Target .22 LR, both with available 6-inch barrel lengths. CLICK HERE for a good, side-by-side video review of these two rimfire revolvers by popular YouTube host Hickok45.

With inflation, the increased cost of .223 Rem centerfire ammo has driven more folks to shooting .22 LR rimfire ammo, both for fun and practice. Thankfully, handy conversion kits will let you shoot .22 LR ammo from your existing .223/5.56 AR-15 platform rifle. This allows low-cost training with no change in rifle balance, ergonomics, and/or optics.
The CMMG Bravo .22 LR Conversion Kit provides a replacement bolt/bolt carrier along with three 25-round magazines with special .22 LR-fitted followers and ammo slots. This allows you to shoot rimfire ammo from any AR-15 chambered for the .223 Rem (5.56×45). The CMMG Bravo has an integrated extension that fits into your current chamber. The rimfire bullet passes through this extension and then enters the barrel. This conversion kit is now on sale at Brownells for $179.99 with three 25-rd mags.
The CMMG Bravo conversion Kit comes with blowback-operated .22 LR bolt carrier, rubber protector for bolt carrier tip, and three 25-round polymer magazines. To use, simply replace the rifle’s .223 Rem bolt and carrier with the Bravo .22 LR conversion unit and load up the included magazine(s) with rimfire ammo.
To use the CMMG Kit, simply remove the centerfire bolt/bolt carrier, and replace it with the CMMG silver colored bolt shown above. CMMG states: “For best performance use a round-style hammer as notched hammers can cause function issues.” Testers have stated that high-velocity .22 LR ammo works best, and CMMG notes that “36gr plated-nose bullets have proven to be the best choice for function.” The copper-plated bullets help reduce fouling.
Ultimate Reloader Tests CMMG .22 LR Conversion Kit
Our friend Gavin Gear of UltimateReloader.com recently tested the CMMG .22 LR AR Conversion Kit. He observed that installation was very straight-forward and the CMMG magazines worked well. He and fellow tester Travis Fox shot the unit both slow-fire and rapid-fire successfully.
Gavin and Travis found the CMMG Kit easy to install and fun to use. With an AR that can shoot both .223 Rem and .22 LR, it’s like having “two guns in one”. Travis was impressed with the ease of use: “It is so simple to change over to the CMMG .22 LR AR kit! It took me about 68 seconds the very first time I tried. Each time after that it took me about 40 seconds — it’s that simple. It takes longer to fully load one of the mags than it does to switch over from .223/5.56 to .22 LR and back.”
The AR shot very well with the higher-velocity ammo types. 100% functioning was achieved with both 40gr Federal Game Shok ammo and American Eagle High Velocity 38gr Copper-plated HP ammo. NOTE: CMMG does recommend high-velocity Copper-plated rimfire ammunition.
Maintenance Tip — After converting back to your centerfire .223 Rem (5.56), Travis says “make sure to clean the gas tube and components as .22 LR tends to run dirty”. READ Full Test on UltimateReloader.com.
CMMG Bravo Conversion Kit Gets Thumbs Up from Gavin and Travis
“Does this conversion kit get the Ultimate Reloader stamp of approval? Absolutely! In these times of ammunition/component scarcity this gives options to shooters. Finding bulk .22 LR can sometimes be easier than 223/5.56. This kit gives that option at a great price. Any chance to keep skills up and familiarize new shooters to a platform is a good thing. Basically two rifles for a lot less than another rifle.”
How to Install CMMG Bravo .22 LR Conversion Kit
The Brownells video below shows the installation process step-by-step:
In this instructional video, a Brownells gunsmith demonstrates (step by step) how to install, disassemble, clean, lubricate, and reassemble the CMMG AR-15 .22 LR Conversion Kits. Clear the rifle and make safe before you start the conversion. Separate the upper and lower, remove the standard bolt carrier group. You then install the conversion bolt and connect the upper and lower as normal.
Details of CMMG .22 LR Conversion Kit
“For years I’ve had a CMMG conversion kit. It’s a drop-in system that’s … very reliable and it’s accurate. The [CMMG conversion] has lower recoil [and is] great for training. Even though ammo prices have gone through the roof, .22 LR is still cheaper to shoot than anything else.” — SootchGear

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.
CCI has produced four versions of Clean-22 rimfire ammunition:
