What was old, is new again… RCBS has just introduced an all-new balance beam scale, the RCBS M1000 Scale. RCBS claims this magnetic-dampened scale will weigh up to 1,000 Grains with +/- 0.1-grain accuracy (one-tenth of a grain is about three kernels of Varget). The new M1000 mechanical scale features a magnetic damping system for fast readings, and maintenance-free movement. A newly-designed “tip-proof” pan should ease powder loading. Notably, the M1000 scale was designed to work in both right-handed and left-handed configurations. Curtis Smith, RCBS Product Director, explains: “For those who choose mechanical scales, accuracy and reliability are top priorities. The new M1000 scale provides exactly that for both left- and right-handed users.” The scale is quite affordable — it is available now at Amazon.com for $129.59. (MSRP is $159.45.) For more information, visit www.RCBS.com.
Triple Poise Operation with 1000-Grain Capacity
The scale has some interesting features, including three poises (weight index adjusters). The main poise goes to 1000 grains, while the medium poise runs up to 20 grains. The most precise small poise spans one grain in tenth of a grain increments. The rated capacity of the RCBS M1000 scale is 1000 grains.
Multiple Reference Pointers for Target Weights
The M1000 also features multiple pointers which can be used to set target weight ranges. This speeds up operations. According to the M1000 Users Manual: “[There are] three separate pointers for easy reading of over and under loads. The center Pointer is what is used when balancing the scale and establishes a ZERO Balance. The top and bottom Pointers represent approximately 1.5 grain above and below target load. The top and bottom pointers allow the user to quickly weigh loads knowing that if the beam pointer is oscillating between the top and bottom pointers the load is within +/- 1.5 grains. Having top and bottom pointers also eliminates the need to move the small poise to check powder charge variations.”

Flat-bottomed stocks are great for benchrest shooting, but their geometry is not ideal for mounting conventional Harris bipods, which were originally designed for stocks with a curved underbelly. Long-time Forum member Mark S. wanted to know if there is a way to make a stud-mounted bipod more secure on a flat-bottomed stock: “I have started shooting some steel matches that require shooting from bipods. My best gun for the job is a 6BRX in a MBR benchrest stock. I have installed a stud, but the bipod is still wanting to turn sometimes. What do you use?”
Here’s a solution for Mark and others using Harris bipods on flat-bottomed stocks with studs. Get the Harris-made #9 (HB9) adapter. Costing just $21.26 (at Midsouth), the HB9 adapter provides an extended contact surface with pads, so the bipod will fit securely on your flat fore-end.The HB9 adapter also has a center cut-out for the swivel stud so the bipod adapter aligns properly on the underside of your stock:
Recently the CMP adopted new rules that allow the use of magnified optics, up to 4.5X power, in Service Rifle competition. The Nightforce NXS 1-4x24mm Compact Riflescope, while not designed specifically for Service Rifle competition, complies fully with the new Service Rifle optics rules and works very well. In fact, our correspondent Johnny Fisher used this scope to take third place in the recent California State Service Rifle Championship. Here’s a run down of the scope’s features and performance. Johnny says this is a “great scope” and “results are extremely promising” so far.
Gear Review: Nightforce NXS 1-4x24mm as Considered for Service Rifles by Johnny Fisher
2016 has brought with it a long anticipated rule change that allows for the use of optics in Service Rifle competition. The rule allows scopes (fixed or variable) up to 4.5 power with an objective lens no greater than 34mm. Given the strict limits on max magnification and objective size for Service Rifle optics, there are somewhat limited options on the market at this time. Service Rifle competitors are now challenged with selecting an optic that fits the rules while offering high-end performance. Thus far, it seems the biggest concerns that Service Rifle shooters have when considering an optic are: quality, repeatability, parallax, reticle choices, and durability.
Click Image for Full-screen Version.
The vast majority of Service Rifle Rule-compliant scopes currently on the market have a fixed parallax. That means there is no separate focus knob to adjust parallax to target distance. Accordingly, there has been much concern about the potential for parallax error over the three different distances in Across-The-Course competition. It is possible that the repeatably-indexed head position maintained while shooting a Service Rifle, along with a little extra emphasis on sight alignment to ensure that the shooter’s eye is directly behind the scope, can greatly mitigate the potential effects of parallax error.
The Nightforce NXS 1-4x24mm comes with the parallax factory-set at 75 yards. Combined with the right amount of eye-relief and low-enough rings to ensure an easy-to-maintain and clear/full sight picture, it seems like the fixed parallax is not really the problem some folks think it may be. Below are two, 10-round test strings shot at 300 yards (each with a magazine change). Note that I didn’t drop a point, even with the non-adjustable parallax.
The Fixed Parallax is not a “deal-breaker”. Witness 20 shots at 300 yards — all 10s or Xs.
For the NXS 1-4x24mm scope, Nightforce offers two reticle types: the International Hunting Reticle (IHR) and the FC-3G (with 5.56 NATO or .308 NATO BDC hold-over features). My scope has the IHR Reticle, which provides a very clear, unobstructed and simple sight picture. The IHR reticle for the NXS 1-4x24mm boasts an illuminated center cross-hair. Unfortunately, the red-color illumination is really only intended for low-light situations and is not bright enough to offer any aid to National Match shooters competing in broad daylight at stationary targets.
For Service Rifle shooters accustomed to keeping track of their sight settings as “clicks from bottom”, the optional Zero-Stop might be welcome. After loosening the turret and establishing the desired Zero-stop location, tightening the set screw blocks rotation below this point. NOTE: Once set, the Zero-Stop turret only allows for one full revolution of elevation adjustment. However, the Nightforce NXS 1-4x24mm offers 20 minutes of elevation adjustment per revolution. That should be more than enough elevation adjustment for come-ups to 600 yards (even with a 100-yard zero established near bottom).
PRICE and DURABILITY
The Nightforce NXS 1-4x24mm carries a price tag of just over $1500.00. The scope just feels solid –nothing plastic — especially when compared to some of the other consumer- or recreational-grade options on the market. All touchable tolerances feel extremely tight. There was quite an amount of attention given to every little detail, as you would expect from an optic at this price point. It is hoped that the scope’s mil-spec robustness will assure continued excellent performance — even after seasons of the kind of abuse that High Power shooters put on their equipment. More will be revealed as I use the scope at future competitions, but initial results are very good. This is a quality optic. I have high hopes that it will prove a good investment.
The 6.5 Guys, a dedicated duo of Pacific NW rifle shooters, have created an interesting series of shooting-related videos on their 6.5 Guys YouTube Channel. In a pair of YouTube videos, The 6.5 Guys set up and demonstrate the Bench-Source cartridge brass annealing machine. The videos offer valuable tips on setting up the machine, attaching and adjusting the torches, and fine tuning the flame and dwell time to achieve best results.
To complement their videos, the 6.5 Guys (aka Ed and Steve) have published an Annealing Tech Talk article on 65guys.com. If you own an annealing machine, or are getting started with cartridge annealing, you should read that article. It covers basic annealing principles, and gives useful tips on temp control, dwell time, and frequency of annealing. After the video, we feature highlights from this article.
We use 750° Tempilaq applied inside the case neck to indicate that the proper temperature has been achieved. If you turn off the lights, you will notice that the brass just barely starts to turn color. As you go beyond the 750° mark we observed that the case mouth will start to flare orange — you can see this with the lights on. From our research, we understand that this is the result of zinc burning off. We adjust the time on our machine between the point that the Tempilaq turns liquid and the flame starts to turn orange. In other words, if the flame is starting to turn orange reduce the time. We let the cases air cool — we don’t quench them in water.
The case starts to flare orange here, during a set-up test. Dwell time was then reduced slightly.
We aim the flame at the neck-shoulder junction. Some folks like to aim it at the neck and others the shoulder. When you see how the two flames meet and spread out vertically, it probably doesn’t make that much of a difference.
Here you can see the flame points aimed at the neck-shoulder junction.
Cases will turn color after annealing, but the degree of color change is not a reliable indicator. We have noticed that the appearance of cases will vary depending on brass manufacturer, brass lot, light source, and how long ago the case was annealed.
How Often Should You Anneal?
Some shooters anneal every time while others choose a specific interval. We noticed work hardening around five firings that resulted in inconsistency in shoulder setback and neck tension, so we choose to anneal every three firings. Your mileage will vary depending on how hot your loads are and how aggressively you resize.

Pac-Nor Production Manager Casey Dichter says the Sunnen hone produces a consistency in bore diameter that is much superior to hand-lapping. The Sunnen machine has all but eliminated the standard pre-rifling lap. “You can really tell the difference between a bore that was honed before rifling and one that was [only] lapped”, notes Dichter.
Gun Barrel Honing System Hits Target for Pac-Nor Barreling
Manufacturing precision rifle barrels has always been something of an art that involves hand lapping of the bore surface twice, before and after the rifling profile is cut or swaged in by a rifling button. In fact, a bright, hand-lapped bore is considered one of the hallmarks of a precision rifle barrel, despite the inherent variations from manual work done by people who get bored and tired from the monotonous chore. Pac-Nor Barreling, Inc. set its sights on this issue more than a year ago and hit the X-ring with the newly developed Sunnen HTE honing machine. The machine has all but eliminated Pac-Nor’s pre-rifling lap, which is the more difficult and time-consuming of the two laps. Pac-Nor is also producing as many custom barrels as ever, but with a slightly smaller staff. “Our objectives with the hone were to build a better product with less labor, and the honing machine has exceeded my expectations,” said Pac-Nor Production Manager Casey Dichter. “The hone produces a consistency in bore diameter that is head and shoulders above lapping, within two to three millionths of an inch end-to-end when it’s really dialed in,” he said. “This, in turn, improves the consistency of the rifling process by minimizing variation in the depth of the grooves. We still finish lap after rifling, but it’s easier because we just polish off the fine crosshatch finish that may be left after honing and rifling.”
The Sunnen hone secures the barrel blank in a 3-jaw chuck, with honing oil pumped into one end while the tool works from the opposite end. Sunnen’s specialized Long Bore Tool uses metal-bond diamond or CBN superabrasives to quickly remove reamer marks, waviness, tight spots and other imperfections left by upstream processes.
Honing is an ideal replacement for hand lapping barrel blanks before rifling. It quickly removes reamer scratches and surface waviness without labor-intensive hand lapping. A typical 600-grit abrasive can produce a 6-10 microinch Ra (0.15 to 0.25 µm) finish in a reamed barrel blank. By producing a consistent bore diameter (±0.0001″ or less), parallelism, roundness and surface finish end to end, honing yields more consistent performance from rifling buttons and cutters, resulting in a constant groove depth. The ideal bore geometry reduces distortion of the bullet shape.
Pac-Nor’s barrel-making process starts with cutting and facing premium bar stock, followed by gun drilling, done by four Pratt & Whitney twin-spindle machines and an Eldorado CNC twin spindle. After reaming, the barrels are gauged for size. Depending on the condition of the reamer, 0.0004″ to 0.0007″ of material is left in the bore. This must be manually lapped out or honed out to final size for rifling. “Everyone who works here has done hand-lapping,” said Dichter. “It’s an unpleasant job, particularly if the reamer is starting to get dull. Lapping may take 10 to 45 minutes, depending on the caliber of the barrel. We tried to shorten this, but when chatter marks get ‘ironed’ into the surface by the rifling button, the finish lap is even longer and more difficult, so there is no advantage. With lapping, too, there is potential for variation, simply because it’s a manual process. Lapping can also be a production limiter and in our region we have a very small labor force to draw on when we want to grow.”
Pac-Nor cuts and faces premium bar stock, then gun drills on one of five twin-spindle machines, followed by reaming of the blanks. This rack of barrel blanks awaits completion.
The company had explored honing in the nineties, but re-visited the idea when Sunnen introduced its HTE honing machine in 2014. The HTE is a horizontal machine that can hone small-bore rifle barrels, with a diameter range of 0.150″ to 0.790” (4-20 mm), and lengths up to 60″ (1,524 mm). Designed specifically for long small bores, the machine features an extremely sensitive drive and tool feed system that provide maximum protection against tool overload/breakage. Tool specific force limits and run settings are stored in the touch-screen PC control, allowing the system to sense tight sections in the bore and correct them automatically.
Sunnen also developed a new Long-Bore Tool (LBT) designed to take on industry’s most difficult honing challenges in small bores of .17 caliber rifle barrels. The tool quickly remove reamer marks, waviness, tight spots and other imperfections left by upstream processes. The LBT utilizes metal-bond diamond or CBN super-abrasives for high productivity, long life and fast cycle times. Precision-machined of through-hardened tool steel, the LBT can produce bore accuracies of 0.000027″ (0.0006 mm) for diameter, roundness, and taper – from first part to last.
“We are currently honing about 80 percent of what we make and will do more as we acquire the tools in different calibers,” said Dichter. “Although there is a trade-off in cycle time and abrasive cost for additional honing, we are still able to run our reamers two to three times longer than when we lapped alone. With a hand lap, the time and effort increase when the reamer is getting dull.”
After honing, each barrel is inspected again before rifling with a pull-button. Pac-Nor makes its own Accu-Twist carbide rifling buttons and can provide different rifling styles, including polygonal, per the customer’s choice. A button is attached to a rod and the rod is pulled through the barrel. The company’s hydraulic rifling machine utilizes a CNC-machined twist bar with a helix angle that matches the twist rate requested by the customer. The final twist rate is confirmed afterward using a Barrel-Scan electro-optical twist measurement system.
The barrel is then stress-relieved in a tempering furnace, followed by contouring of the outer shape and final, finish lapping of the bore. “During the finish lap, you can really tell the difference between a bore that was honed before rifling and one that was lapped,” said Dichter. “You can easily sense any remaining tight or loose spots in the bore. The diameter uniformity and roundness of the honed bore are superb. The lap also feels different in a honed bore.”
In competitive shooting where winning scores may be separated by thousandths of an inch, a few millionths of an inch improvement in the uniformity of a Pac-Nor barrel may make a big difference for a skilled shooter. For more information, visit www.sunnen.com or contact:

In recent years, the use of electronic trainer systems has revolutionized training in all disciplines of position shooting. By capturing (and illustrating) key performance variables like the steadiness of a shooter’s hold, accuracy of aiming, and the timeliness of trigger release, these devices can offer tremendous insights into the strengths and weakness of a shooter’s position and technique, making high-level marksmanship training less voodoo and more of a science.
Until now, electronic trainers all suffered from one critical limitation: the inability to be used outdoors in live fire training. Now, however, SCATT has introduced the next-generation MX-02 electronic trainer, a product that can finally support outdoor live firing in broad daylight, as well as dry firing indoors. In addition, the MX-02 is the first electronic trainer to support centerfire rifles. It goes without saying that, when we at AccurateShooter.com were offered an MX-02 test unit to review, we jumped at the opportunity.
How the SCATT MX-02 Works
The SCATT sensor mounted on the end of the barrel has a digital camera that “sees” 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. Data points from the trace are also available in a tabular spreadsheet format. This allows the shooter to “crunch the numbers”, revealing strengths and weaknesses in his gun-handling and aiming technique.
In our testing, we confirmed that, like SCATT’s earlier indoor-only WS-01, the MX-02 offers excellent support for indoor dry-fire training, which will continue to be the primary means through which position shooters sharpen their fundamental skills. Since the new SCATT uses the same familiar Windows software for data capture and analysis as its predecessors, shooters and coaches upgrading to MX-02 will have no learning curve to overcome, and newcomers to the SCATT platform can tap into the wealth of institutional knowledge accumulated over the years by the shooting community on how to interpret shot data.
It’s in the support for outdoor live firing, however, that SCATT MX-02 distinguishes itself from its predecessors and the competition. Shot trace data captured by MX-02 during live firing turned out to be every bit as valuable (and revealing) as we had hoped. The ability to correlate SCATT tracing with real shots on target gave us a better understanding of the shooting process, and helped the reviewer, already a high-level smallbore prone shooter, uncover a significant problem in his shooting. SCATT MX-02’s outdoor capability is therefore an invaluable feature, particularly for experienced shooters aspiring to world-class performance.
In summary, SCATT MX-02 is an outstanding product that delivers on its promises. We heartily recommend it, both for first-time users of electronic training aids, and also for those shooters who may wish to upgrade their current electronic training system. The MSRP for SCATT MX-02 is $1,799, $500 more than its predecessor, the SCATT WS-01, which is still available. In my view, the $500 premium for the MX-02 is justified by the MX-02’s enhanced capabilities, making it a better long-term investment.
Our complete, 3600-word MX-02 review of the SCATT MX-02 can be accessed through the link below. This full review contains many more photos plus detailed field test results. For the time being, the review only covers our experience with the product in smallbore shooting. An upcoming addendum to the review will include test results from centerfire shooting. Those attending SHOT Show in Las Vegas next week can examine SCATT MX-02 in person. SCATT will have the MX-02 on display at Booth 111.
You probably know by now that David Tubb has introduced a new two-stage trigger for Remington 700 rifles, the Model T7T. Priced at $385.00, the new T7T Trigger is a true two-stage design: first and second stages are independently adjustable for both weight and feel. Overall (combined stage) trigger pull weight can be adjusted from just under 1 pound to slightly over 3.5 pounds.
If you are interested in the 7ZT, watch these two videos. The first shows how to adjust pull-weights for both stages. The second video shows how to modify your stock to provide clearance for the T7T.
This video shows how to adjust the new Tubb T7T two-stage trigger for Remington 700s:
The new T7T is a quality product. We’ve received good feedback from “early adopters” who tell us the two-stage function works well. While installation of the T7T may require minor modifications to your action, most gun owners with basic mechanical skills can install the T7T by themselves. The T7T is made using stainless steel and aluminum for maximum corrosion resistance. Note, installation of the T7T trigger (either Right-Hand or Left-Hand) also requires a companion T7T bolt release, offered by DavidTubb.com for $10.00.

Forum member Rick from Louisiana (aka RMulhern) has rigged up a fantastic target for long-range shooting. Rick, a long-time competitive Palma shooter, had a large 72″x72″ steel target fabricated with two separate center rings that are equivalent to the official paper Palma/Creedmoor target. He says he’s “shot a lot of Palma on that target, as well as lots of Black Powder Cartridge (BPCR) rounds”. The big steel target works great when Rick shoots his Sharps 45/110 BPCR at 800 to 1000 yards. The large steel background (painted white) helps Rick see and hear his hits. If you understand the high-arching trajectory of 500+ grain projectiles shot from a 45/110, you know it can take a few rounds to get Point of Impact dialed in.
Rick reports: “These are two of my favorite rifles to shoot: a M1874 Shiloh Sharps in caliber 45/110 (2 7/8) made in Big Timber, Montana by Kirk Bryan and family. The other is a 6.5×47 Lapua on a blue-printed M700 action with 1:8.5″-twist Krieger barrel and F5 McMillan Tactical stock. Many of the shooters that take up BPCR have a tendency to get away from their smokeless powder rifles in favor of the blackpowder game. Frankly I have the best of both worlds as I enjoy shooting both (smokeless and BPCR), although I must admit that I probably spend the majority of my time on the range with the Sharps rifles these days.” (Rick’s pretty good with his Sharps by the way — he recently shot a 95, 96, and 100 (clean) for 3×10 shots at 800 yards.)
Gongzilla: $1000 Worth of Steel with Three Plate Layers
Rick tells us: “Here’s the deal — everything is steel! The large plate is 72″x72″ and the black bull is 44″ diameter. The 20″-diameter central white bull is made from 1/2″-thick AR400 bull-dozer plating. That’s the same size as the regulation Palma/Creedmoor paper target. The white square and black bull are 3/8″-thick mild steel. Plates are off-set 2″ from each other. I welded a 2″ length of square tubing to the back of both plates and the bolt slides through and is attached to the large plate. I used 2 3/8″ upset tubing (oil field pipe) for the holder framing.” Rick says he invested about $1000.00 in metal for the target, but that was 15 years ago. Today the steel would be much more expensive.
Rick says the AR400 armor plate in the center bull is very strong: “You can shoot a .338 Lapua Magnum at 200 yards and it won’t damage the center bull”. The mild steel works well for the cast bullets Rick uses with his Sharps 45/110. Also, Rick says the mild steel is rugged enough for 6.5mm and .308 hollowpoint match bullets, if you’re at least 500 yards away. However, Rick told us, “If I would make [the target] again, I would make the black bull AR400 as well. [That way] you would never have to worry about big dents or beating the plate up at any distance. The AR400 is very tough steel. You can shoot a Sierra or Lapua HP bullet and they will just splatter.”
Rick told us: “I built this target with off-set clanger plates. The white clanger is AR400. Bullets just splatter!” Does he worry about hitting the bolt head? Not at all. Rick says: “When I hit the bolt head, I break my arm patting myself on the back!”.

Varminter.com recently released a First Hunt Report on the new Savage A17 rifle. Savage’s new semi-auto .17 HMR has caused quite a stir. Accurate and affordable, the Savage A17 is also the first .17 HMR to feature a delayed blow-back action. We think the A17 may be the most important new rimfire rifle of 2015, so we were pleased to see that Eric Mayer, Editor of Varminter.com, put the new semi-auto Savage through its paces.
Mayer wanted to see how the new Savage would perform, accuracy-wise, and he also wanted to see how the A17 fared in the field. Mayer achieved one-MOA accuracy with the Savage A17 using the latest CCI-brand ammo, and he demonstrated the A17 is wickedly effective on ground squirrels. Below we’ve provided highlights from Varminter.com’s Savage A17 First Hunt Report.
Most shooters know Carl Bernosky as a 10-time National High Power Rifle champion. But you may not realize that Carl is also a very talented stock-maker and rifle-builder. Carl crafts a wide variety of wood and wood laminate stocks for competition as well as hunting. He also crafts many stocks for Alex Sitman of Master Class Stocks.
Master Class Low-Profile F-Open Stock
Here is a new Master Class Low-Profile F-Open Stock crafted by Carl Bernosky. It is made from a Cherry/Maple wood laminate. This design features a railed fore-end along with a flat, parallel toe for improved tracking and stability on the bags. The front section of the fore-arm has a low profile. This allows the barrel bore axis to ride lower. That helps reduce hop and helps the gun recoil straight back. For more information on this low-profile F-Open stock design, visit Carl Bernosky’s Facebook Page and MasterClassStocks.com.
Note that the stock maintains full depth under the action and quite a few inches forward of the action. This smart design feature is very important. We have seen other low-profile stock designs that can flex or “hinge” forward of the action because there’s not enough wood material there. In fact, the only part of the stock that needs a cut-down profile is the front 10″ or so, where the stock actually rides the front bag.
This particular stock features a “pop-off” magnetic cheekpiece, as well as a buttplate that adjusts for Length of Pull (LOP) via spacers. The action is by Pierce Engineering. This and other Master Class Stock designs can be customized with other features on request.

Wouldn’t it be great if you could quickly and easily adjust shoulder bump during the full-length sizing process, without struggling to move die lock-rings by trial and error (or fiddle with shims). Well you can. The PMA Micro Die Adjuster is a brilliant little device that replaces the lock ring on your FL sizing die. It allows you to move the die up and down in precise, tiny increments. The tool has .001″ index marks, but you can easily set your die between the marks to achieve .0005″ (half-thousandth) adjustments.
To see how the PMA Micro-Die Adjuster works, watch this video by our friend Boyd Allen:
Many of our Forum members now use the PMA Micro Die Adjuster, and they give this specialty tool high praise. Here are actual reviews by Forum members and other verified tool buyers. Read more comments in this AccurateShooter Forum Thread.
PMA Micro Die Adjuster User Reviews
“No more ‘close enough’ for headspace[.] With this tool set-up it’s easy to put headspace exactly where you want it, then repeat it exactly for subsequent batches for the same cartridge.” — JohnF
“I have four of these Micro Adjuster rings and all I can say is that it works and it is repeatable. I bump my brass .0005″-.001″ and this die lock ring will do it without issue.” — TrapperT
“I size brass for four different 6.5×47 rifles (chambered with three different reamers) using a single die, set in the PMA Adjuster. I have to say… I should have bought one sooner. Adjusting it is very quick and repeatable to well under .001.” — /VH
“Great product. Shims used to drive me crazy, put a .002 in and get .0035 of change. With this if you want .0015 set it and that’s what you get.” — John B
“I’ve been using PMA’s lock ring for some time now and find it to be very easy to adjust to within .0005″ on a single piece of brass. Very quick to do as well. One thing I have found is that if you still need that half-thou adjustment I will run the brass once more at the same setting before I make that .0005″ adjustment and 50 percent of the time that does the trick. The marked increments are in .001″ scale so if you go half way in between there’s your half-thousandth.
PMA Micro-Adjuster vs. Shims: With respect to using shims, that requires you to completely remove the die. That gets old rather quickly after having used the PMA adjustable lock ring.” — Patch 700
“I like mine — adjustments are easy and it will adjust very fine. I used to use .001″ shims. Now can adjust my bump as fine as I want.” — Joe139
“The PMA adjuster works just like they say it does and is very simple to use and adjust. I use JLC inserts as well … as nice as they are you’re still hobbled by a click. However with the PMA you can go between what would be clicks. And you can use them … with any die.” — Dusty Stevens
Product Description from PMA Tool
The PMA Tool Micro Die Adjuster (MDA) replaces your existing lock ring and can be used with nearly any 7/8-14 full length sizing die. We successfully used this tool with sizing dies from Redding, RCBS, Hornady, Lee, Harrells Precision and those made from Newlon Precision die blanks. It allows you to easily make adjustments to your “shoulder bump” as fine as .0005″. The engraved marks on the MDA are equal to approximately .001 inches (true adjustment .000992″) of adjustment to the shoulder bump. Splitting the engraved marks is therefore approximately equal to .0005″. The design of the MDA does not allow it to work with the Forster Co-Ax press. Some custom dies for very short cartridges may require the use of an extended shellholder. Micro Die Adjuster shown in use installed on Custom Newlon/Scott 6mm PPC Die and Harrells Precision Compact Press.

We really like rimfire revolvers here at AccurateShooter.com. A good .22 LR wheelgun will be fun, accurate, reliable, and inexpensive to shoot. Rimfire revolvers also offer much less recoil and noise than a centerfire pistol. Your Editor has owned a Smith & Wesson Model 617 for over 15 years. That old S&W has probably fired more rounds than all the other handguns I own, combined — yet it still runs flawlessly and still delivers excellent accuracy.
Ruger recently came out with a new, stainless .22 LR wheelgun to compete with the S&W Model 617. This new rimfire wheelgun is based on Ruger’s trusted GP100 platform. The new Ruger® GP100® chambered in .22 LR looks to be a good firearm — strong, versatile, and intelligently engineered. In the video above, 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.
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. A number of changes have been made to the GP100 to handle .22. One of which is 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 for comfortable shooting. This is a really comfortable gun to shoot”.

Jay Christopherson is AccurateShooter.com’s systems administrator — he keeps the servers up and running. Jay is also a very talented rifle shooter who holds a carry permit. Recently, Jay acquired a Walther PPS M2, a compact, defensive carry pistol. Here Jay reviews that pistol, which is now his “go-to” handgun when he chooses to carry a firearm pursuant to his CCW permit.
The Walther PPS M2, Single-stack 9mm is a Comfortable, Reliable Everyday Carry Pistol.
Looking for a new carry pistol in a single-stack, 9mm configuration, I tested out the slim (1″-wide) Walther PPS M2, with three different magazine capacities. For someone who has carried a 5″-barreled, .45 ACP model 1911 for the last few years, the switch to a single-stack 9mm was a big change — but a welcome one in terms of weight and comfort. I like my big 1911, but the PPS M2 gives me the feeling that if it’s needed, it’ll be a safe, effective, and reliable option. I still love my 1911, but when it comes to carry, the 1911 will stay in the safe while I “pack” the smaller, lighter PPS.

Like many of AccurateShooter.com’s readers, I have a permit to carry a concealed firearm and I use the privilege regularly. I’m no great shakes with a pistol, having focused most of my efforts on long-range rifle shooting, but I do spend enough time at the pistol range to ensure that I am familiar with my weapon and comfortable shooting it out to ranges where I might encounter a situation requiring its use.
Part of being responsible is selecting a carry weapon that you can be comfortable with, both using and carrying. Now, I’ll admit that I’ve focused a lot on the former, but not as much on the latter. I’m an unabashed fan of John M. Browning’s crowning (in my opinion) achievement, the Colt .45 ACP M1911. My current 1911, with a 5” barrel, is not the easiest pistol in the world to carry comfortably. While I love shooting it, carrying it is another situation altogether. I’ve tried many different configurations, but found myself carrying it less and less.
And so, I decided that I needed to enter the world of the 9mm single stack for a carry weapon. There are a lot of reasons why I chose to go that direction, but it’s a highly subjective and personal subject (some of the arguments out there are pretty heated), so I won’t bore you with mine. Suffice it to say, there’s plenty of available information for you to make an informed decision. To help with testing, Walther Arms was kind enough to provide a new Walther PPS M2, in 9mm, for evaluation.
Three Magazine Options
Along with the PPS M2, Walther provided three magazines — the 5-round standard mag plus 6-round and 7-round extended magazines. I tried all three magazines, both for carry/fit, and at the range to see if they would affect my ability to shoot the pistol. For reference my hands are roughly 9.25″ wide — according to the Internet, the average hand size for a male is 7.44″, so I guess I’ve got larger than average hands. The shortest magazine was a bit too short for me to grip comfortably — my pinky finger had zero engagement and my two-hand grip suffered for it. The middle magazine let my pinky engage the grip partially, but was still not ideal. The longest magazine fit perfectly. My guess is that if your hand is in the average range, the middle magazine will work for you. For women, I think the smallest grip will work nicely. My wife has an average hand span for females and thought that the smallest grip felt pretty natural for her.
The trigger is fair — the takeup is smooth, the trigger breaks relatively cleanly and predictably, but a rough spot on the Glock-style trigger safety lever wore against my finger, leaving it feeling a bit raw. It’s fairly minor and something that can easily be resolved. And even with my larger fingers, I still had no problem with trigger guard clearance. Disassembly is fairly easy, though the take-down lever takes some effort to work. [Editor — on the PPS M2 I tried at SHOT Show, the small slide-stop lever was hard to manipulate.]
After having carried my 1911 around quite a bit, I found the Walther PPS M2 to be much lighter and easier to carry (I use a Clinger holster). I rarely notice it, even when getting into and out of a car. With the PPS M2 it’s easy to carry without “printing”, at least with the appendix carry method I prefer.
General Function and Accuracy Testing
I took the pistol down to the range to test it out and get a feel for it. I bought a variety of 115 grain FMJ ammunition to test including PMC and Blazer brass-cased 9mm. I ran about 400 rounds through the little Walther. None of the ammo experienced any sort of issue and the pistol never failed to perform flawlessly. With 400 rounds through the PPS M2 cleanly, I am confident to carry the PPS M2 when I feel the need to carry.
I set up targets at 15 feet and 30 feet — remembering that I’m looking for a personal defense/carry pistol and that I don’t practice for competition! At both ranges, shooting all three magazines, I had no problems putting together groups that are more than accurate enough for “center mass”.
During a second testing session, I shot the pistol for accuracy with my forearms rested on sandbags. The results were impressive. Above is a seven-shot (7-shot) group at 10 yards (30 feet) with the CCI Blazer Brass ammo. At right is a group shot at 5 yards (15 feet), forearms rested, with the PMC ammo. The one shot that went up outside the group was probably me, the shooter. Remember this is a very small, light-weight pistol that does have some muzzle flip. I’ve seen other tests done with the Walther PPS M2, at longer ranges in the hands of skilled shooters and producing much cleaner groups.
Summary — Walther PPS M2 is a Keeper
Overall, I really like the 9mm single stack Walther PPS M2. It’s a very handy, manageable pistol. After testing the gun for AccurateShooter.com I decided to purchase the pistol and keep it. That’s the ultimate vote of confidence. This gun shoots comfortably, accurately and reliably, and most of all, the PPS M2 is comfortable to carry. When I choose to carry, should I ever need a firearm, I have every confidence in the Walther PPS M2.

The Lyman Borecam is an electro-optical borescope with a digital display. You can record “stills” on a SD card. This is one of the hottest products on the market right now — so hot that it has been sold out for weeks. But Grafs.com just got a shipment of Borecams (item LY04055), and the price is more than competitive. Right now Grafs has the Borecam in stock for $259.99 with free shipping (after a single $7.95 handling fee). That price is $40.00 less than some other online vendors are charging.
This is a good product. Guys who purchased the Lyman Borecam are very happy. If you don’t have one yet, now may be the time to “pull the trigger”. After this article goes live, we expect Grafs.com to sell out quickly. Graf’s inventory may be gone by end-of-day today.
Our British friend Vince Bottomley did an extensive review, giving the Lyman Borecam high praise. Vince says serious shooters should definitely acquire one of these tools: “In my opinion, this product is one of the very best to come along in recent years and I predict that the demand for these [Lyman Borecams] will be very heavy. I would advise you to place an order as quickly as possible if you want one.” Vince adds: “If I were to replace my [Hawkeye optical borescope] today with another Hawkeye, it would cost me well over £700 [$1015 USD]. Stick on a video adapter and we are looking at four figures. That’s what makes the new Lyman digital borescope so attractive — at around [$260.00 USD] including a monitor — it’s an absolute steal!”
The system really works. Many of our Forum members have the system and they say it functions very well and is “very easy to set up and use”. Here’s what an Optics Planet Borecam buyer wrote: “I have used Hawkeye borescopes and know their quality. The Lyman worked as advertised and is a great tool for checking for leading, cleanliness of bore, and bore wear. The compact size, ability to take pictures, and store them are a big plus.”

PMA Tool offers lightweight yet sturdy cleaning cradles that are handy, affordable, and easy to transport. PMA’s single-gun cradle, priced at $69.95, is ideal for benchrest rigs. It measures about 17″ in length and weighs about one pound. PMA now also offers a two-gun cradle for $112.95. Both single and double cradles secure your rifle(s) in a muzzle-down position that allows easy cleaning and prevents solvents from running back into the action. The front “saddle” and all contact surfaces are covered by thick silicone rubber padding which grips the rifle securely yet protects the stock and components from scratches.
These cradles are currently available either with a 3″-wide front saddle for Benchrest and F-Open style stocks, or a 2.5″-wide front saddle for rifles with narrower narrower, flat fore-ends such as those found on Hunter Class and modern varmint stocks.
Double Rifle Cradle is a Smart, Versatile Design
PMA’s double rifle cleaning cradle was was designed from the ground up to work perfectly for two rifles side-by-side. Using the same tie bar and protective saddles found on the single cradel, PMA widened the base and created new uprights to support the saddles, making the cradle as narrow and light as possible, while retaining all the protective and non-slip features from our single unit. This unit is available in double 3″ front saddles, double 2.5″ front saddles or combination 3″ / 2.5″ front saddle configurations to accommodate multiple classes of rifles for centerfire and rimfire benchrest competition.

How well can factory .308 Win ammo perform? Amazingly well it seems. Our friends at Criterion Barrels recently tested some .308 ammo from Creedmoor Sports. This was loaded with Lapua’s 175gr Scenar HPBT bullet. The results speak for themselves. Any time factory ammo can shoot inside quarter-MOA, that’s impressive. This ammo was used in a “Rem/Age” project rifle. That term refers to a Remington action rifle that has been re-barreled with a pre-fit Criterion barrel. The new barrel is secured with a Savage-style barrel nut. Hence the term “Rem/Age” or “Rem-Age”.
Criterion posted: “I think we may have a new favorite factory match load for the nitrided Rem/Age build.” Another reader added: “[Creedmoor’s] 175 Scenar .308 ammunition is top notch.” FYI, this group was shot on our load development target, which you can download for free from our Targets Page.
Why do Criterion barrels shoot so well? One reason is that Criterion’s barrel steel is carefully stress-relieved. In the photo below, Criterion Rack 1A (aka the “Coffin”) has been loaded with barrel blanks — made ready for the stress-relieving process.

Our British friend Vince Bottomley has field-tested the brand new Vortex 15-60x52mm “Golden Eagle” riflescope. We first viewed this scope at SHOT Show and were impressed. Now Vince, in a Target Shooter Magazine review, has confirmed that that the scope works great in the real world. It has good glass, excellent tracking, and the image stays sharp even at full magnification. Vince says this 15-60X Vortex will give other high-magnification scopes a run for their money. In fact the Vortex Golden Eagle may be the new Performance-for-Price leader in the category. Price in the USA will be $1500.00.
Vince writes: “The Vortex deserves to line up alongside the competition – namely the March 10-60, the Nightforce 15-55 and the Leupold 7-42. The price is remarkable at [$1500.00 in the USA, under £1500 in the UK]. If you are contemplating the purchase of a scope in this magnification range, the Vortex must be on your shopping list.” This new Vortex features ED glass, and weighs 29 ounces, just one ounce more than the 15-55X Nightforce Comp. Two reticles are available — a Fine Cross-Hair (FCH), and the Vortex ECR-1 reticle with MOA-based windage and elevation hold lines. Turrets have 1/8 MOA clicks.
Precision of Clicks: Does one MOA (i.e. eight 1/8 MOA clicks) on the Golden Eagle’s turret translate to one MOA on the target? Vince fired one shot on target then wound on 20 MOA of elevation and fired another. Vince reports: “The shot-holes should be 20.94″ (20 x 1.047″) inches apart. They actually measured 21.5 inches — an excellent result. I don’t think I’ve ever had a scope better this.”
Elevation Travel: F-TR shooters using the .308 Win will need about 30 MOA to get from a 100-yard zero to 1000 yards. Vince maxed out the Golden Eagle with roughly 22 MOA of “up” elevation. He concluded that “a +20 MOA scope-rail is a ‘must’ if you’re intending to shoot out to 1000 yards. These days, almost everyone uses a 20 MOA scope rail anyway.”
Tracking Test: Vince did a “box test” running the Vortex to the limits of elevation and windage and then back again to verify that the scope returned to the starting zero. Vince observed that the scope tracked great, “with the first and last shots over-lapping. No problem there.”
Glass Sharpness and Clarity: Vince put the the Golden Eagle alongside a 10-60 March, with both scopes mounted on F-TR rifles. Vince was impressed by the optics quality of the Vortex — it held its own vs. the “superb” March: “Firstly, we viewed the target on 40 power, the magnification which seems most popular with F-Class shooters. Both scopes registered bright, crisp images — no difference between the two. I know the March will stay sharp at maximum magnification but will the Golden Eagle? Yes! No loss of crispness in the image at 60X.”
We met with our friend Erik Cortina at the Berger Southwest Nationals this week. Erik (shown above), had a beautiful new F-Open rifle to show us. This features a new, large-diameter Borden action and a Shurley Brothers fancy maple stock. Erik loves great hardware — whether it comes to actions, stocks, or reloading equipment. One of Erik’s favorite reloading tools is his Forster Co-Ax press.
Cortina has produced a series of YouTube videos about reloading hardware and precision hand-loading. Here is Erik’s video review of the Forster Co-Ax® reloading press. The Co-Ax is unique in both design and operation. It features dual guide rods and a central handle. You don’t screw in dies — you slide the die lock ring into a slot. This allows dies to float during operation.
Erik does a good job of demonstrating the Co-Ax’s unique features. At 1:00 he shows how to slide the dies into the press. It’s slick and easy. At the two-minute mark, Erik shows how sliding jaws clasp the case rim (rather than a conventional shell-holder). The jaws close as the ram is raised, then open as it is lowered. This makes it easy to place and remove your cases.
At the 5:20 mark, Erik shows how spent primers run straight down into a capture cup. This smart system helps keep your press and bench area clean of primer debris and residues.
While many Co-Ax users prime their cases by hand, the Co-Ax can prime cases very reliably. The priming station is on top of the press. Erik demonstrates the priming operation starting at 4:20.
Smart Accessories for the Co-Ax from Inline Fabrications
Lapua’s Kevin Thomas also owns a Co-Ax press, which he has hot-rodded with accessories from Inline Fabrications. Kevin tells us: “Check out the add-ons available from Inline Fabrications for the Co-Ax. I recently picked up a riser mount and a set of linkages for mine and love the results. The linkages are curved. When you replace the original straight links with these, the work area opens up substantially and the the press becomes much easier to feed.” CLICK HERE for Co-Ax Accessories.

Sinclair International has a good article on Case Lubrication which shows the various products and application methods available. Part of Sinclair’s Step-By-Step Reloading series, the article shows how to apply Spray Lube, Die Wax, or conventional lube from a Pad. The story also explains how to use dry lube to slick up the inside of your case necks.
High-volume reloaders often turn to spray-on lubricants such as the RCBS Case Slick (#749-001-341) or the Hornady One Shot (#749-001-065) to quickly lubricate large numbers of cases at once. An indispensable piece of gear that helps make spray lubing easy is a lube rack (#749-011-550) — a polymer block that holds cases upright and arranged to maximize their exposure to the spray.
Editor’s Note: Ballistol Aerosol is other good spray product for regular full-length sizing (not heavy case-forming). It goes on clear (no chalky residue), it is ultra-slippery, and it will remove the carbon from your case necks as you apply Ballistol with a patch. This is my primary spray lube — but many folks dislike the distinctive Ballistol smell. Try before you buy.
Sizing Die Wax
Over the years, many benchrest shooters have come to trust Imperial Sizing Die Wax (#749-001-052) for their case lube needs. It offers high lubricity and easily wipes off with a paper towel. In fact, its lubricity makes it a popular choice for case forming, for those wildcat folks who need to form their own unique or obsolete cartridges. Unlike lube pads or spray lubes, sizing wax is applied more naturally. You just put a little on your fingers and transfer it to the cases by handling them. As simple and easy as Imperial Sizing Die Wax is to use, it’s probably best for low-volume applications.
Redding’s Imperial Application Media (#749-001-166) is a dry neck lube used to lube the inside of the neck, whether you’re full-length sizing or neck-sizing only. It consists of ceramic spheres coated with a fine graphite-based powder. You simply dip the neck into the container for a second to pick up the right amount of lube. This lube enables the expander ball to work smoothly throughout the case neck –instead of “grabbing” or “chattering” — to minimize case neck stretching.
Editor’s Note: Dry Lube is also very useful if you ultrasonically clean your cases. After the ultrasound process, the inside of the case neck can be so “squeaky clean” that bullets don’t seat smoothly. A quick application of dry lube will help bullets slide into the neck easier and the neck “grip” on the bullets should be more consistent from round-to-round. Consistent neck tension is key to accuracy and uniform velocities.

Close-up of the Tri Way cutter with clear plastic chip guard removed.
When you hear the name Giraud Tool you probably think of big, heavy, bench-top motor-driven trimmers. Well Giraud also offers a handy case trimmer/chamferer that works with a power drill (or other power source). Giraud’s patent-pending Tri Way Case Trimmer is a self-contained unit powered by your drill or motor. Using a sharp carbide blade it will trim your cases to length, deburr, and cut both inside and outside chamfers — all in one pass. That’s pretty impressive for a $98.00 tool that fits in the palm of your hand.
1. Fully adjustable for cartridge length (and depth of chamfer).
2. Tool includes carbide blade that cuts a 15° inside case mouth chamfer and 45° outside chamfer.
3. Case holder supported by sealed ball bearing raceway.
4. Tool includes removable, transparent plastic chip guard.
5. Tool can work in any orientation (vertical, horizontal, or any angle).
The Giraud Tri Way Trimmer is designed to be powered by a portable hand drill, drill press, or other dedicated rotating power source. The tool indexes off the shoulder of your cases, but the blade adjusts so that cartridge overall length (COAL) can be controlled with precision. Constructed out of 6061-T6 aluminum and 303 stainless steel, the Tri Way tool should last a lifetime. Note: This tool is not universal. The Tri Way is dedicated to a single cartridge and “related” cartridges with similar body dimensions. Thus you need a specific tool for each cartridge family. For example, the .308 Win tool will also trim .243 Win, .260 Rem, and 7mm-08.
Cartridge Sizes Available for Giraud Tri Way Trimmer:
.223 Remington (Also trims .17 Remington, .204 Ruger, .222 Remington, .222 Remington Magnum)
7.62 x 39mm (Russian)
.300 Blackout (Also trims .17 Rem Fireball, .221 Fireball)
