The King Cobra Target 22 LR is a great wheelgun from Colt Mfg. Co. (“Colt”). It is accurate, has a great trigger, and holds its value well. 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 five barrel options: 2″, 3″, 4.25″, 6″, and 8″ barrel lengths, all with 1:16″ RH rifling twist. The MSRP for all models is currently $1119.00, but you should be able to find one under $900.00. For example the 4.25″ and 6″ King Cobra Target are each under $885.00 at Guns.com. In addition, Colt is currently offering a $100 Rebate on Colt Revolvers, including the King Cobra Target 22 LR models.
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: “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 should deliver exceptional accuracy and good reliability. Watch the video to see this rimfire revolver in action.
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 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 CMP has opened Registration for the 2026 National Matches at Camp Perry, Ohio. Since the turn of the 20th century*, Camp Perry has hosted major marksmanship events. While the rifle competitions get the most coverage, the Camp Perry National Matches also include bullseye pistol competitions. Traditional Bullseye pistol shooting can bring nearly a thousand competitors to Camp Perry each summer, as part of the CMP National Championships. For these Camp Perry pistol matches, held July 12-18, 2026, targets are set at 25 and 50 yards. The shooting position is standing and firing one-handed in slow fire, timed fire, and rapid-fire.
Since their inception over a century ago, the National Matches have become a major shooting sports festival with over 4,500 annual participants. Held at the Camp Perry Nat’l Guard Training Base, the National Matches now include both indoor and outdoor events. Adult and junior athletes are welcome.
Camp Perry Bullseye Pistol Competition
Camp Perry is synonymous with the oldest and most prestigious annual trophy matches in our nation’s history. And in a venue renowned for service rifle matches, the sport of precision pistol is no less important, no less challenging, and no less respected. The National Trophy Pistol Matches is all about traditional handgunning — the stance, the intense concentration, and of course, the one-handed grip. It’s all unmistakable as the game of Bullseye Pistol. Every year there are no fewer than 24 separate match trophies for the top Bullseye Pistol shooters, both military and civilian. And the very best will claim National Match Trophies and receive the President’s 100 Tab.

Tumblers and walnut/corncob media are old school. These days many shooters prefer processing brass rapidly with an ultrasonic cleaning machine. When used with the proper solution, a good ultrasonic cleaning machine can quickly remove remove dust, carbon, oil, and powder residue from your cartridge brass. The ultrasonic process will clean the inside of the cases, and even the primer pockets. Tumbling works well too, but for really dirty brass, ultrasonic cleaning may be a wise choice.
Our friend Gavin Gear has evaluated an RCBS Ultrasonic cleaning machine using RCBS Ultrasonic Case Cleaning Solution (RCBS #87058). To provide a real challenge, Gavin used some very dull and greasy milsurp brass: “I bought a huge lot of military once-fired 7.52x51mm brass (fired in a machine gun) that I’ve been slowly prepping for my DPMS LR-308B AR-10 style rifle. Some of this brass was fully prepped (sized/de-primed, trimmed, case mouths chamfered, primer pockets reamed) but it was gunked up with lube and looking dingy.”
UltimateReloader.com Case Cleaning Video (7.5 minutes):
Gavin describes the cleaning exercise step-by-step on UltimateReloader.com. Read Gavin’s Cartridge Cleaning Article to learn how he mixed the solution, activated the heater, and cycled the machine for 30 minutes. As you can see in the video above, the results were impressive. If you have never cleaned brass with ultrasound before, you should definitely watch Gavin’s 7.5-minute video — it provides many useful tips and shows the cleaning operation in progress from start to finish.
Ultra Dry Necks After Ultrasonic Cleaning — Some Suggestions
The Ultrasonic cleaning process gets cartridge brass so “squeaky clean” that increased force may be required to seat your bullets, or they may “grab” as they go in the necks. To reduce bullet-seating effort, you may benefit from adding a little dry case lube inside the case-neck before loading (use a nylon brush). Another trick is adding a teaspoon of Ballistol lube to the cleaning solution. That provides a trace lubricant inside the necks, but does not interfere with powder ignition in any way.
The latest Gen2 RCBS ultrasonic cleaning machine has a large 6.3-quart capacity. That’s nearly 100% larger than the first generation machine in Gavin’s video. The Gen2 machine, $434.52 on Amazon, features a second ceramic heater and transducer to better clean brass cases and firearm parts. The LED is easily programmable, and the timer can be set for up to 30 minutes of cleaning. The original 3.2 quart-capacity RCBS ultrasonic machine, as shown in Gavin’s video, is still available for $213.99 at Midsouth Shooters.

Want to show off some groups you’ve shot? Or keep a handy pack of mini-targets in your range kit? Then check out this unique product from stockmaker Bell & Carlson. Shoot’n Aces cards feature a 1-inch black square aiming box with a 1/2-inch inner square. These cards are normal poker-playing-card size, 3.5″ high x 2.5″ wide (89 × 64 mm). Shoot’n Aces cards come 56 to a pack. Carry a few extras in your wallet or a pack in your vehicle glove compartment and you’ll always have a precision target to shoot at the range. Cards can be stapled or taped to target stands.
Sniper Central says these cards work well as targets: “The bold square is easy to pick up with the inner white portion making a nice aiming point. The material of the cards is the same as normal playing cards and the bullets make a very nice hole when passing through.” The sharp edges of the bullet holes makes it easy to measure group sizes with precision.
Each pack of Shoot’n Aces contains 56 premium-quality target cards. If you want some, order Bell & Carlson item SA-2006. This is a set of four (4) card-packs with 56 cards per pack (224 cards total) priced at $20.00 (i.e. $5.00 per pack).

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 rifles featured in that popular 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.
Rimfire F-Class Rig with Curly Maple Stock
This handsome, ultra-accurate Smallbore F-Class rig belongs to member RMist of Team Pro-Shot Products. It has a Holeshot (Stiller) 2500X, stunning Cerus Curly Maple wood stock, Nightforce scope. Up front is the joystick co-axial SEB Joy-Pod.
How does this impressive rimfire F-Classer shoot? Amazingly well. That target at right shows TEN (10) rounds fired at 100 yards. Most centerfire rifles would have trouble beating that level of accuracy.
Rimfire Tactical Rig with CZ Action and McRees Precision Chassis
Here’s a modern chassis rig built with a CZ 455 action. Forum member A-Rob upgraded the CZ 455 with a SCAR 2-stage trigger. This rifle features a Keystone Accuracy-fitted glue-in barrel, Athlon 10-40x scope and McRees Precision chassis. As you can see from the target, it shoots great. Note: CZ has replaced its 455s with the new CZ 457 series with available metal chassis precision model. CLICK HERE to see full target sheet with six 5-shot groups at 50 yards, averaging 0.270″.
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.
Do you own an RCBS electronic powder dispenser? If you do, take the time to watch this ChargeMaster Tuning video from 8541 Tactical. This nine-minute video demonstrates how to re-program your ChargeMaster to “tune” the dispensing process. The video shows the exact programming procedures to follow, step-by-step. Some folks want a faster powder flow — others tune their machines for a more reliable drop (with fewer over-runs). One cheap and popular modification is to insert a 1″-long section of a McDonald’s plastic straw in the ChargeMaster’s silver dispensing tube. This works surprisingly well to smooth kernel drop and prevent “clumping” that can cause an over-charge. The McDonald’s straw MOD is demonstrated in this video, starting at the 6:22 mark.
Large-Diameter Dispensing Tube Mod
Many folks have had success with the McDonald’s straw modification demonstrated in the above video. However, some folks would like to get even better flow performance (with virtually no clumping). Forum Member Frank B. has come up with a new option using a brass hose fitting with a large outside diameter. The hose fitting (with tape wrapped around the barbed nose section) is placed inside the RCBS dispensing tube (have some kind of wrap — you don’t want metal-on-metal). Here’s how the unit looks installed:
Frank tells us: “I have found a cure for the over-throw problem. It is a simple 1/4″ barbed hose nipple. I wrapped a couple layers of tape around the barbed end for a snug fit. With this in place, I have thrown 100+ charges of Varget without a single overthrow. The ID of the barbed end needs to be approximately 3/16″ to feed a steady flow. This works because of the larger ID at the drop.”
Frank adds: “You can see in the photo that the powder is not stacking up. You can watch it drop one grain at a time. Hope this will take the aggravation out of your case charging.” For best performance with this brass fitting MOD, we recommend de-burring and smoothing out the front edge of the brass fitting over which the kernels drop.
Brass fitting mod suggested by Boyd Allen. We welcome reader submissions.
