Our friend Dennis Santiago was doing some dry firing practice recently, using a SCATT sensing device. This electro-optical unit shows a trace of barrel/muzzle movement on a computer screen, allowing a shooter to improve his hold and aiming. With practice, you get steadier, and learn to break the shot more perfectly. Top position shooters worldwide use this system. Dennis tells us: “This is my dry fire practice set up. I’m working on my approaches to the target today. You need the SCATT’s traces to see the feedback of what’s going on.” Here is one trace from Santiago’s morning training session:
Dennis trains indoors at his house: “The set-up is in a room with the target about 15 feet away mounted on a scope stand at eye height and aligned. This morning, it’s focus and trigger control. My offhand form is gonna get there bit by bit. There are many details to turn into instincts.”
SCATT MX-02 Training System
The SCATT MX-02 is an electronic shooter training system that is capable of operating outdoors with live, centerfire ammunition, at distances from 25 yards to 600 yards. Tony Chow tested this product for AccurateShooter.com. As fitted to his AR-15 Service Rifle, Tony concludes this is a very useful tool that can help High Power competitors refine their technique and shoot higher scores. FULL REVIEW HERE.
How the SCATT MX-02 Works
The SCATT sensor mounted on the end of the barrel has a digital camera that recognizes the black bullseye in the target, even in broad daylight outdoors. Using the bullseye as a reference, the SCATT software tracks the movement of the muzzle relative to the center of the target. The unit can plot these movements as a continuous trace, which appears on a monitor as a squiggly, colored line. By sensing the exact moment of shot release, the SCATT can also interpolate relative shot placement (for a single shot or series of shots) — but this is not the same as an electronic target which actually records the exact shot impact location on the target.
Pro shooter Kirsten Joy Weiss demonstrates the SCATT MX-02 electronic training system:
The system traces and records valuable information such as hold pattern, shot hold duration, follow-through, recoil pattern, and much more. The latest SCATT MX-02 systems can be used both indoors and outdoors up to 300 meters (and possibly more). READ FULL SCATT MX-02 TEST HERE.
SCATT traces reveal muzzle movements during the aiming process.
Sako has a new S20 line of “hybrid” rifles. These feature an internal aluminum chassis, adjustable trigger, and integral Picatinny rail on top. Users can change fore-ends and rear sections to suit different disciplines. Use the rifle for a PRS match one weekend and hunt with it the next. Sako states: “The user will be able to switch between the stocks and fore-ends quickly and easily and can change the rifle from a tactical to a hunting rifle or vice versa in a matter of minutes with no need to re-zero optics after assembly. The stocks can be taken down easily by loosening up two screws between the rear stock and fore-end.” Both 20″ and 24″ barrel versions will be offered, with a wide variety of chamberings: .243 Win, 6.5 Creedmoor, 6.5 PRC, .270 Win, 7mm Rem Mag, .308 Win, .30-06 Sprg, .300 Win Mag.
Unboxing Video of New S20 with Thumbhole Hunter Stock
This S20 “first look” video was created by the UK Fieldsports channel. The reviewer was impressed with the S20’s interchangeable stock system: “The modularity allows the rifle to be configured to the shooter’s preferences with different rear stocks and fore-ends. At launch, Sako introduced both the tactical precision stock and the ergonomic hunting stock, the latter being an improved version of a traditional thumbhole stock more like a pistol grip. Switching between rear stocks is fast and easy, virtually changing the rifle from a target rifle to a hunting rifle, or vice versa, with the correct grip, in a matter of minutes.”
The S20’s aluminum chassis is covered by a strong but comfortable outer shell material that Sako calls H.I.R. – High Impact Resistant. The same H.I.R. material is used on car dashboards. The outer shell is currently offered in two styles — a thumbhole hunter (photo below) and a more tactical style with straight toe and conventional grip.
The Picatinny rail is machined directly on the receiver. The S20 action features a 3-lug bolt with 60° bolt throw. Sako says the “high locking-lug surface area increases both safety and performance.” The full length of the action mates with a matching V-bed in the aluminum chassis.
Full Adjustability — Even Trigger Position
Adjustable ergonomics are a big part of the S20 design. The multi-adjustable trigger (available in both single-stage and two-stage variants) can be moved backwards or forwards to better fit different hand sizes. An adjustable cheek piece and LOP spacers help provide a proper fit.
M-Lok System Allows Easy Mounting of Accessories
The new Sako S20 can accept a wide range of accessories, attached via aluminum M-LOK placements. Sako-made accessories include Rear Mono-Pod, Barricade Stop, and Thumbrest. And yes Sako threads the muzzles 5/8×24 for use with brakes and suppressors. This video shows how accessories mount:
The Sako S20 features a full aluminum chassis under a comfortable composite exterior. Watch this video to see how the S20’s barreled action fits in the chassis.
Velocity vs. barrel length — How much speed will I sacrifice with a shorter barrel? Hunters and competition shooters often ask that. Today we DO have solid answers to that question for many cartridge types thanks to Rifleshooter.com.
Bill, Rifleshooter.com’s Editor, explained his test procedure:
“I gathered four different types of factory Federal 224 Valkyrie ammunition, the 90gr Sierra MatchKing (SMK), 90gr Fusion soft point (SP) (referred to a Fusion MSR), 75gr Total Metal Jacket (TMJ) and 60gr Nosler Ballistic Tip Varmint (NBT). After a brief barrel break in and zero, I fired 5 rounds of each cartridge at each barrel length (except the 75 TMJ, I fired 4 rounds at each barrel length due to limited resources). I recorded the average muzzle velocity and standard deviation for each ammunition and barrel length combination and cut the barrel back 1 inch and repeated the process. I recorded barrel lengths from 28″ to 16.5″ (I try to save these barrels as finished 16″ tubes so they don’t go to waste).”
The Heavy Bullet 90gr Ammo Lost about 21 FPS per Inch
How did the test turn out? You’ll find all the results summarized in helpful tables with inch-by-inch velocity and SD numbers. For the two, 90gr ammo samples, results were similar. The 90gr SMK ammo started at 2782 fps (28″), finishing at 2541 fps (16.5″). That’s a loss of 241 fps, or 20.96 fps average per inch of length. The ammo loaded with 90gr Fusion SPs started at 2797 fps (28″) and ended at 2561 fps (16.5″), a drop of 236 fps. That’s 20.5 fps loss per inch. NOTE: Ambient temperature during the test was 45° F. You could expect the overall velocities to be a bit higher during hotter summer months.
With a the smaller bullets, the effect was even more dramatic. As you’d expect they started out faster. The ammo with 60gr Nosler Ballistic Tips (NBT), a good choice for varminters, started at 3395 fps (28″), and declined to 3065 fps (16.5), a total velocity drop of 330 fps. Average velocity loss was 28.7 fps per inch of barrel length. Rifleshooter.com also tested Federal 75gr TMJ ammo.
About the .224 Valkyrie Cartridge
The new .224 Valkyrie was introduced late last year as a Hot Rod cartridge that will work in AR15s. Designed to rival the .22 Nosler while still running well in ARs, the new .224 Valkyrie offers excellent long-range performance when loaded with modern, high-BC bullets. We expect some bolt-action PRS shooters might adopt the .224 Valkyrie. Why? Reduced recoil. With the 90gr SMK, the .224 Valkyrie offers ballistics similar to the 6.5 Creedmoor but with significantly less felt recoil. Check out this chart from Federal showing comparative recoil levels:
.224 Valkyrie vs. .22-250 Remington
The Social Regressive explains: “There are two key reasons why the .224 Valkyrie is unique and desirable. First, it is specifically designed to fit the limitations of the AR-15 platform. It does so even when loaded with gigantic bullets, like the 90-grain SMK that Federal announced. The .22-250 Rem is too long and too fat to work in the AR-15 platform; it needs an AR-10 bolt and magazine.”
The new .224 Valkyrie is basically a 6.8 SPC case necked down to .22-caliber. You can use your existing AR15 lower, but you will need a dedicated .224-Valkyrie upper, or at the minimum a new barrel, modified bolt with proper bolt face, and 6.8-compliant mags.
Whidden Gunworks has the long-awaited Barnard SMS action. This impressive new 3-lug Rem-footprint action is NOT just another Remington 700 clone, though it fits Rem-inletted stocks and chassis systems. The Barnard SMS is a high-quality, custom-grade action. With the 3-lug design, bolt handle lift is shorter and quicker than its top competitors. And the excellent trigger timing of the SMS provides a smooth, glass-like operation.
New Zealand-crafted Barnard actions, such as the venerable Model P, have been highly coveted in the competitive long range community based on their high quality, ease of maintenance, and superb performance. Here in the USA, customers have asked for the same Barnard quality in a format that allows the use of Rem 700-configured stocks, triggers, magazines, and other accessories. This new SMS action can be used for long-range competition, PRS, benchrest, silhouette, hunting — any application where Rem 700-type actions are popular.
This new SMS action works with the Rem 700-family accessories which are readily available on the market. No adapters or conversion blocks are necessary for this action. The Barnard SMS is a true drop-in fit with Rem 700-inletted stocks and chassis systems. Likewise magazines and triggers for the Remington 700 footprint fit and work 100% with the new Barnard SMS.
Whidden Gunworks states: “Sportsmen all over the world will agree to the unequaled and superb quality of Barnard actions. The internal parts are simple and robust. Disassembly and maintenance can be easily done in the field if needed quickly, returning your firearm back into service. Quality material and proper heat-treating methods ensure strength and longevity for a lifetime of use. The new Barnard SMS is a great new offering.

In a recent Forum thread, one member asked for recommendations for a factory rifle with a good action and trigger, under $600.00. Many respondents recommended a Tikka T3 (or newer T3X), and we concur. These won’t run with a $2500 custom, but for a hunting or varminting rig, they offer good bang for the buck with a very nice action. The last Tikka T3 we tried, a .308 Win with 24″ barrel, easily shot sub-MOA groups with factory ammo.
The original Tikka T3 and newer T3x actions are rigid, robust, and well-crafted. They cycle smoothly and have a short 75° bolt lift. The bolt features a Sako-style extractor, with angled-leading-edge bolt lugs for smooth lock-up. These T3/T3x rifles offer smooth-running actions, easy sub-MOA accuracy with good ammo, crisp triggers, and ultra-reliable detachable box magazines. The Tupperware stocks aren’t super-rigid, but they are comfortable and easy to handle.
If you are looking for a hunting rifle, the Tikka T3/T3x is a smart choice, offering good performance for the price (which starts at $569.00 for the T3X Lite version). The current T3x series is offered in a wide selection of chamberings, from .204 Ruger up to the large magnums.
We were impressed with the new Tikka T3x UPR rifle we saw at SHOT Show 2020 We liked the stock very much, and thought this was a very versatile gun that could be used for target shooting off bipod, hunting, even PRS, given its detachable magazine. The stock is very ergonomic and feels good. Tikka states the UPR’s stock “features an extra layer of carbon fiber mixed with fiberglass for increased rigidity and accuracy.”

Tikka T3 Upgrades — Barrels, Stocks, and Chassis Systems
Once you acquire a Tikka T3 there are many interesting upgrades available. First, you can improve accuracy and consistency with a pre-fit barrel from Criterion. There are also many chassis systems that fit Tikkas. In fact you can even get an Eliseo Chassis so you can shoot Palma matches F-TR competitions, or tactical/practical matches.
Criterion Pre-Fit Barrels for Tikka T3/T3x
We have always liked Tikka actions, and now there is a great re-barreling option for Tikka T3/T3x owners. Criterion Barrels Inc. (CBI), makers of “pre-fit” barrels for Savage, Remington, and Rem-clone actions, also crafts Tikka pre-fits. These pre-chambered barrels for Tikka T3 actions will be headspaced with a barrel nut, just like a Savage.

Tikka T3/T3x pre-fit barrels are sold through Solid Accuracy, a respected Texas-based outfit that sells high-end scopes, stocks, barrels and other rifle components. Price is $461-$485 with various contours and lengths available. Order HERE.
Competition Machine Chassis for Tikka T3
At SHOT Show, we saw some tactical shooters admiring the smooth Tikka T3 action and crisp trigger. They liked the action but they told us they wished they could get the T3 action in a configuration similar to the Ruger Precision Rifle. Well folks, there is a way to build a Tikka T3-based tactical/practical rig.
Gary Eliseo of Competition Machine offers a tubegun chassis for Tikka T3 actions in both Target and Tactical versions. The T3 kit is set up for AICS short action magazines. This is a “no gunsmithing” installation — no modifications to the action are required and the chassis kit works with the factory T3 trigger and safety. Along with the new Target and Tactical versions, a lower-cost Light-Weight Hunter T3 Chassis is also offered which accepts most AR-type buttstock assemblies.
Full Tactical Upgrade for Tikka T3
Tikkas are boring, nondescript hunting rifles right? Wrong. Check out this Tikka T3 tactical with “attitude”. For the British Shooting Show a while back, the folks at Osprey Rifles placed a Tikka T3 action into a modern modular chassis: “A standard factory Tikka T3 was fully Cerakoted and dropped into a Third Eye Tactical chassis stock which also had the Cerakote treatment.”
Click Photos to see full-screen version.
This T3 Chassis can be ordered through Osprey Rifles in the UK. The latest chassis stock system from Third Eye Tactical is currently available for both the Rem 700 short action and the Tikka T3.

Sometimes simpler is better when it comes to targets for fun shooting and load testing. While we normally use test targets from our Downloadable Target Page, it’s sometimes easier to just use brightly-colored “Hi-Viz” adhesive target dots.
Hi-Viz Stick-On Dots in Assorted Colors and Diameters
You can order 1″ target dots in bulk from Labeloutfitters.com. Many colors are available including fluorescent (hi-viz) Red, Green, Orange, and Yellow. These are bright and easy to see even in fading afternoon light. A pack of twenty (20) sheets (1260 dots total) costs just $5.97 (that works out to $4.74 per thousand). For the 1″-diameter stick-on dots you get 63 dots per sheet. Larger, 1.5″-diameter fluorescent dots are also available in 20-sheet packs for $5.97, with 24 large dots per sheet (480 dots total). If you want even bigger, 2″-diameter dots, sheets with 20 Hi-Viz dots per sheet are on sale for $5.97 per 20-pack (400 dots total).
Our friend Danny Reever really likes the bright dots from Label-Outfitters: “Ordered some of the 1″ dots from LabelOutfitters.com and received them in two days Priority Mail! Bought the fluorescent red,green, and yellow and they are really nice — especially for the price.”
If you prefer smaller, 3/4″-diameter circles, Amazon.com sells Avery packs with 1008 adhesive dots for just $4 to $7 per pack. Colors include Neon Red/Orange (item 5467), Neon Yellow (item 5470), Neon Green (item 5468), and Bright Blue (item 5461). We recommend the Neon Red/Orange for most uses, or the Neon Yellow dots for use on a black background. There is even a dispenser-box option with 1000 3/4″ dots on a roll in a box. Amazon.com also offers 3/4″ and 1″-diameter target pasters in 1000-dot rolls for $7-$10 per roll.
Half-Inch Fluorescent Dots for 100-200 Yards
For close-range work, you may prefer 1/2″-diameter dots. Forum member Steve found a source for very small 1/2″ dots: Uline.com. The 1/2″ dots are available in a wide variety of colors including fluorescent Red, Pink, Yellow, and Green. Price is $12 for a roll of 1000 dots (item S-2063). Steve notes: “A 1/2″ circle at 300 yards is not quite entirely covered by Nightforce crosshairs at 42-power (I’d say 70% coverage). I.e., it seems easier to line up repeatedly than with the bigger (3/4″) circles, which I used to use. Note that, for me, neon green and neon orange work best on brown cardboard targets. Neon orange works well on white paper.”
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 site 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 strongly 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.
Smith & Wesson Model 617 Video Reviews
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.
Hickok 45 Demos “Wonderful revolver”, a 4″ Model 617. See also Hickok 45 m617 Part 2:
Popular YouTube Host 22 Plinkster Tests Model 617 with 6″ Barrel:
22 Plinkster loves the Model 617, “one of [his] favorite revolvers in the whole entire world — a great choice”. He reports it “shoots straight [and] functions pretty much flawlessly” with nearly any .22 LR ammo. In this video, 22 Plinkster tests a wide variety of rimfire ammo types including CCI .22 LR Std Velocity, .22 Shorts, .22 LR Shotshells, .22 Stingers, .22 Super Colibri, and .22 LR tracers.

Other Rimfire Revolvers — from Ruger and S&W
If you’re considering a rimfire revolver but would like to see other options, read our Buyers Guide to Rimfire Revolvers. Along with the S&W Model 617, this covers the Ruger GP100 10-shot (5″ bbl), Ruger LCRx 8-shot (3″ bbl), Classic S&W Model 17 6-shot (blued 6″ bbl), and S&W Model 63 (3″ bbl).
TOP FIVE Reasons to Own a Rimfire Revolver:
1. Rimfire .22 LR Ammunition is once again plentiful and affordable. The revolver can shoot all kinds of rimfire ammo — even 22 Shorts.
2. A good, full-size .22 LR revolver will be MORE ACCURATE than the vast majority of semi-auto rimfire handguns. It will shoot all types of .22 rimfire ammo with no cycling issues. With no magazines to jam, a good wheelgun will also be more reliable than most self-loading rimfires.
3. A rimfire revolver can shoot tens of thousands of rounds, with just routine maintenance. The gun can last a lifetime and then be passed on to your kids.
4. On a S&W revolver, it is very easy to tune the pull weight. You can have a safe double-action pull with a very light, crisp single-action release.
5. It is easy to change grips and sights to suit your preference. You can also easily mount a scope on the top-strap.
We first ran this story a few seasons back. Since then we’ve received many questions about this gun, so we thought we’d give readers another chance to learn about this truly innovative, switch-barrel “convertible” rifle. This gun works for both short-range (100/200) and long-range (500-1000 yd) benchrest matches.
You interested in a truly innovative bench gun that can shoot both short-range and long-range matches? Check out Seb Lambang’s original “do-it-all” rifle. This switch-barrel rifle combined two very different chamberings: 6 PPC and .284 Winchester. With that caliber combo, Seb’s covered from 100 yards (LV/HV mode) all the way out to 1000 (LR Light Gun mode). But the dual chambering is not the rifle’s only trick feature. Exploiting the long-range benchrest rules on stock designs, Seb has fitted a 3″-wide, flat rear metal keel to the buttstock. That counter-balances his 30″-long 7mm barrel, improves tracking, and adds stability. Seb built the stock and smithing was done by Australian gunsmith David Kerr.
Detachable Hammerhead Wing Section Plus Fat-Bottom Keel
To further reduce torque and improve tracking, the stock features an 8″-wide, detachable fore-end fixture. This “hammerhead” fore-end section has extended “wings” on both sides, making the rifle super-stable. The hammerhead unit can be removed, leaving the stock 3″ wide for use in registered benchrest matches where 3″ is the maximum width. The photos below show Seb’s gun in .284 Win Long-Range (LR) Light Gun mode, complete with front wings and rear keel.
Yes This Rig Shoots … In Both Configurations, Long-Range and Short
Seb has already used his switch-caliber, switch-barrel rig successfully in competition. Seb tells us: “The gun shot and tracked real well either in 6 PPC LV/HV mode or in .284 Win LG mode. I love it! Back in 2015, with this gun I placed Top 10 for the Two-Gun at the Harry Madden Championship in Brisbane, Australia just a few days ago and took the silver medal for the 500m Flyshoot with the .284 Win on the next day. So who says a switch-barrel rifle can’t (or doesn’t) work?” And get this, Seb finished the stock just four days before the Brisbane match. He glued-in the action the evening before the match and shot it the next day in competition. Pretty impressive we’d say….

Seb Lambang — Indonesian Innovator
Sebastian (“Seb”) Lambang is the designer/builder of the innovative SEB Coaxial rests, some of the best joystick rests on the market. The SEB Mini is a remarkable design — very compact but solid enough to win F-Class matches. And the SEB Neo Rest has become the go-to choice for short-range and long-range benchrest. The NEO folds flat for transport, yet offers extended vertical and horizontal travel and a rest top that can adjust from roughly 2″ wide to over 6″ in width. This Editor uses a SEB Neo for both bench and F-Class shooting and it is my favorite joystick rest. Here’s a video review of the SEB Mini, filmed at the Ben Avery Range in Phoenix:
Seb is actually in the USA right now, competing at the Berger Southwest Nationals (SWN). No he’s not shooting his radical Hammerhead at Ben Avery this year — he’s got a more conventional F-TR rig. He is shooting with the Int’l Pickup F-TR team coached by Dean Wheeler. In the 2/6/2020 Team Palma match, Seb finished with high score for his team, 438-9X.
ADDENDUM — Seb Succeeds at SWN in Sharpshooter Division:
Seb just posted this report from the Berger SW Nationals in Phoenix: “Proud to get first place in Sharpshooter Class in the Long Range Day 1 Aggregate. Super tough F-CLASS match against lots of the best shooters in the USA and some other countries. Thanks a bunch to my gunsmith Alex Wheeler who did a really great job, [providing a] super-smooth timed action. Thanks also to Tom Mousel who did a great job with the super-accurate ammo! Thanks to Will McCloskey for the best laminate wood rifle stock on the market. The rifle shoots GREAT. I really enjoy this match!”. Here is Seb on the firing line at Ben Avery. The rifle rests on the SEB Joy-Pod joystick bipod he created.
[NOTE: The NRA has multiple divisions: High Master, Master, Expert, Sharpshooter, and Marksman. The most elite level is High Master.]
