After we ran a story on the New Mexico War Wagon, readers wanted more details about this well-designed mobile shooting bench belonging to Forum member John H. (aka “Skratch”).
John told us: “My brother-in-law and I built this mobile bench a few years ago. The axle, wheels and tire are a tag axle from a small Chevy car, obtained from a salvage yard for about $35-$40 a decade ago. The tubular frame is drill stem, while the bench-top and seats are 3/4′” plywood. Under the plywood we fitted rails so we can slide our target stand under the benchtop for secure travel. The total cost for everything (including storage box) was about $250-$300.”
We set the bench and seat heights so that, with adults, the rifle sets straight level to the shoulder. For the smaller ‘younguns’ we just use a sofa pillow to raise them up. (Yes, adjustable seat heights would be great.) The ammo box holds our rifle rest, sand bags, spotting scope, and miscellaneous gear. Options are a couple of lawn chairs, and a cooler of brew (for after the shooting is done).

Some readers wanted to know how John’s War Wagon is positioned in the field and if it is ever detached from John’s ATV. John answers: “We do unhook the 4-wheeler for target-checking unless we have an extra along which is usually the case. That way we can level the table front to rear. We have an umbrella from a patio table to provide shade on extra warm days.”
Potential Modifications and Upgrades to the War Wagon
When our buddy Mark LaFevers (AccurateShooter.com’s chief fabricator), saw the war wagon, he was impressed. Mark, a professional welder by trade, is now thinking about building a similar rig — with some enhancements. Mark told us: “The thing I like best about the design is the simplicity. It has enough features to get the job done without any frills, bells and whistles. There is always the danger as one adds items that seem like they would be desirable, that the unit becomes too complex and loses its fun aspect. Still, I would try adding a few things.
I like how the builder has added stabilizers at the seat locations. For areas with steep or uneven terrain , I would consider adding a trailer tongue jack to be able to level front to rear, or disconnect from the ATV to go check targets. I would also consider not hard-fastening the bench-top to the frame, but rather mounting it with screw-jacks to be able to level it independently from the frame, both crosswise and lengthwise. Being able to level the benchtop may not be necessary in flat prairie country, but it would be helpful on hilly or uneven terrain.
I would also make the seat height-adjustable. That would accommodate different shooter body sizes and shapes. Height could be adjusted with a threaded seat column, which you can buy cheaply online. You could even mount a slider to allow front-to-rear seat movement. This would allow you to move back for longer rifles and forward for smaller rifles or Encore-style pistols.
Of course, there are other possible “creature comfort” options. If you really wanted to “pimp your ride”, you could include an umbrella stand, gimbaled beer holder, the mandatory water-misters, and a mobile sound system….
Here’s good news for folks looking for another domestic source of cartridge brass. Federal Premium, the folks who make Federal Gold Medal match ammo, is now offering new, virgin, unprimed cartridge brass for a variety of rifle and pistol cartridge types. The new Federal Premium brass will be sold by Sinclair International, Grafs.com and other popular retailers. Sinclair has Federal brass in stock now for the most popular rifle cartridges, including .223 Rem, .243 Win, .270 Win, .308 Win, .30-06 Springfield, .300 WSM and seven more cartridge types (13 rifle brass types total — see chart below).
Federal’s new brass for reloaders starts at $25.99 for fifty (50) cases of .308 Win Brass. The equivalent of $51.98 per hundred cases, that’s pretty affordable. However, note that some types of Federal brass are much more expensive. For example, Federal’s .300 WSM brass costs $43.99 for fifty (50) cases at Sinclair. Click Here for Federal Premium Brass at Sinclair.
Sinclair Int’l notes: “Federal ammunition has long been prized for its reliability, consistency, and quality. But the only way to get Federal brass for reloads was to save your spent shells or scrounge them off the range – until now. Pristine, unfired, properly head-stamped Federal brass for popular rifle cartridges is now available from the manufacturer, and we’re pleased to offer it.”

In our Shooters’ Forum thread about Portable Shooting Benches, Forum member John H. of New Mexico (aka “Skratch”) showed off a nicely-crafted mobile shooting bench that he can haul with his ATV. This trailer-mounted, movable bench is built on a central tubular spine that also serves as the tongue for the trailer, which attaches to a standard hitch. The bench offers two (2) shooting positions so it works for both left-handed and right-handed shooters.
Up front, for storage, a surplus .50-Cal ammo can is secured to the trailer frame. The V-shaped middle section of the wood benchtop looks to be reinforced with a metal stiffener frame on the underside. The front section of the bench is supported by twin tubular uprights attached to the box-section axle housing. The two wooden bench-style seats (on left and right) ride on a cross-tube. At the ends of that cross-tube are adjustable legs for additional support.
Great Rig for New Mexico Varmint Hunting
There are plenty of great varmint hunting areas in Skratch’s home state of New Mexico — you’ll find some huge prairie dog fields there. But to get the best results on a varmint-hunting field session, you need a solid shooting station that can be easily hauled to new locations as needed. It looks like John (aka “Scratch”) has come up with an outstanding “War Wagon” for his New Mexico varmint safaris.
As we reported a few weeks ago, Bryan Litz has written a new book, Accuracy and Precision for Long Range Shooting. We know many readers have pre-ordered Bryan’s latest book. Here’s the good news. Bryan reports that most pre-orders for the new book shipped yesterday, and the rest will go out today.
We asked Bryan to explain the differences between his original Applied Ballistics for Long Range Shooting resource book and the new Accuracy and Precision book. Here is Bryan’s explanation…
The first book, Applied Ballistics for Long-Range Shooting, covers the elements of long range shooting and explains how all the various mechanisms of external ballistics affect trajectories. It’s also the book that contains detailed drawings, BC and stability data for hundreds of bullets.
The new book, Accuracy and Precision for Long Range Shooting explains the impact of external ballistic effects in terms of “hit percentage”. For example, if you choose to ignore Coriolis Effect in your ballistic solution, how much will your hit percentage be reduced on a 10″ target at 1000 yards? How about a 5″ target at 500 yards? How much would your hit percentage be improved on a 15″ target at 1200 yards if you reduce wind uncertainty from +/-3 mph to +/-2 mph?
There are also numerous performance comparisons between different classes of cartridges. For example: how much higher is hit percentage for a .338 Lapua Magnum than a .308 Winchester for common environments and targets?
The new book identifies accuracy and precision effects and defines their effects separately. Did you ever wonder why it’s so easy to shoot a 10 inch GROUP at 1000 yards, but how difficult it is to HIT A 10″ TARGET at 1000 yards on the first shot? Shooting a 10 inch group is precision, but centering the group is a challenge of accuracy.
It’s quite common for long range shooters to focus 90% of their effort on the precision aspect, and only 10% on accuracy. To actually hit targets, you need a balance of accuracy and precision, with accuracy becoming increasingly more important as range is extended. — Bryan Litz
Sebastian (Seb) Lambang of SEB Coaxial, a brilliant designer and fabricator, has created an ingenious joystick bipod. The first coaxial bipod we’ve ever seen, Seb’s new bipod is a superb example of creative design and smart engineering. This unit gives F-TR and other bipod shooters precise, one-handed control of both windage and elevation. Seb’s innovative joystick bipod is yet one more example of the innovative, advanced engineering we’ve come to expect from his company. We think this guy could be building Formula 1 cars if he set his mind to it. We are fortunate that Seb loves shooting, so he applies his talent to designing and building great new products for the shooting sports.
Seb tells us: “I just finished a prototype joystick bipod, i.e. a bipod with joystick (coaxial) elevation and windage control. This patent-pending bipod is my newest project/invention. As far as I know, there is no one that makes this type of bipod… so it’s probably the only one in the world.” We already know some shooters who want to order Seb’s joystick bipod, but Seb cautions: “It’s not for sale yet. It’s still in prototype step. There is always a rough draft before the masterpiece.”
Seb will test and refine the design in the next couple of months before production starts. But Seb is quite satisfied with the design so far: “The rigidity, ease and comfort of use, and compactness, are already OK in my opinion.” Folks in Europe will be able to see the design very soon. The first real-world test of Seb’s new joystick bipod will be at the European F-Class Championship, slated for November 2-3 in the UK. Seb notes: “I won’t be shooting F-TR in the match, but I will ask some fellow F-TR shooters at the Bisley range to test it, and provide feedback.” Seb invites Daily Bulletin readers to look at the photos and provide comments or suggestions on design enhancements.
Technical Description At the lowest setting with the adjustable legs, the SEB bipod is approximately 6″ tall. At the highest setting, the unit is about 9″ tall. To smooth upward movement of the rifle, Seb designed the coaxial head with “built-in uplift”. The joystick itself is about 10″ long, with a collet-type head. When folded, the new SEB Bipod is relatively compact, about 9″ long x 5″ wide x 2″ thick. Most parts are made from aircraft grade 7000 series aluminum. The current weight of the prototype is 26 ounces (740 grams). Seb is working on reducing weight for the production models.
Joystick Function and Adjustment Range
As with SEB Coaxial front rests, the joystick function is user-selectable. The joystick handle can operate either ‘up for up’ or ‘up for down’, simply by reversing the unit and the joystick. The bipod’s effective windage and elevation range* is approximately 38 MOA horizontal (windage) and 16 MOA vertical (elevation). Seb explains: “That’s not as much as my other rests, but for F-Class use it should be adequate. The finer the adjustment, the better on the target and the smoother the joystick operation. It’s like using a scope with 1/8 MOA adjustment rather than 1/4 MOA.”
*True vertical travel is about 32 MOA but in the field the rifle stock will limit how far you can lift the joysticK. Note also that the adjustment range varies with your set-up geometry. The shorter the distance between the rear bag and the bipod, the greater the travel in MOA. This means that if you extend the distance between rear bag and bipod, you will lose some MOA travel.
Story based on report by Kyle Jillson in NRAblog
Earlier this month, junior air rifle shooters from Georgia faced off against counterparts in Germany during an “internet match” that allowed both teams to keep track of their opponents scores in real-time. The two teams were 4,000 miles apart, but they competed simultaneously, with scores from both countries posted instantly (in both venues) via internet connections.
Each shooter was ranked and paired against the corresponding member of the opposing team – like golf’s Ryder Cup. Instead of a team aggregate determining the outcome, countries earned points for beating their opponents.
The US team was set up at the Ole Mill Range in Griffin, Georgia, while their German opponents were shooting from from Untergrombach, Baden-Wuerttemberg, in southern Germany. American and German teams, separated by 4,000 miles and a six hour time difference, came together on a fall day to shoot a fun match between one another – simultaneously. Instead of waiting for results from one another and shooting on different days, it was great to see the two groups work out schedules that allowed competition as if they were all at the same range.
Instead of a normal 60-shot standing match, the two ranges agreed to tweak the rules to the head-to-head format for a little international fun. All shooters still shot in the same relay with scores reported as they came in and “wins” were counted after each pair had finished.
How did the US team fare? I’m sure they’ve seen better days. Outshot in all but one match, the United States lost to Germany 3-1. Despite the defeat, this match was a great example of the shooting sport’s international strength. This “internet match” opened all kinds of doors for future matches between not only different countries, but different states within the USA. The ease of communication through computers can really help the shooting sports expand with a web of competitions the world over.
Serious reloaders know that PMA Tool makes some of the best specialty reloading tools you can buy. To help folks get the most out of their 21st century products, the company has created a new informational website. PMA’s Pat Reagin explains: “We have created a side-site, linked off of our main website, that is just for information. We will adding new product tips regularly. On this page we will post in-depth information about our tools, videos, customer-submitted information and photos, as well as a calendar of shooting events.” You can access PMA’s “At the Bench” info site at: atthebench.pmatool.com.
One highlight of the new PMA info site is a section dedicated to PMA’s new Micro-Adjust Case Trimmer. Pat tells us: “We’ve had quite of bit of interest in the new case trimmer, but a lot of guys want to see it in action. So we’ve created a couple of videos featuring the new trimmer. The first intro video, linked below, shows how to adjust and use the trimmer in various modes. We also produced a longer, 14-minute Instructional Video with more detail on trimmer adjustment and set-up.”

The PMA Micro-Adjust Case trimmer indexes off the shoulder but it also provides precise control over neck length. You aren’t limited to a built-in, neck-length setting like some other shoulder-indexed trimmers. The PMA Micro-Adjust Trimming tool currently sells for $119.95 including one cartridge insert. The inserts, which can be purchased for $13.95 separately, can often work for a multiple cartridge types within the same family. For example, you can use the same insert for both .243 Win and .260 Rem. There is another insert that works with both 7mm-08 and .308 Win.
PMA Micro-Adjust Case Trimmer Features:
Indexes off shoulder for easy, consistent trim length.
Cases captured in no-scratch, Delrin™ inserts.
Fully rotating head with bearing for smooth operation and clean, square cuts.
Sharp carbide cutter for quick, smooth cuts with minimal burr.
Spring loaded head allows complete control of rate of feed.
How to use the PMA Micro-Adjust Case Trimmer
The trimmer indexes case off the case shoulder through the use of interchangeable Delrin™ inserts which capture the shoulder and neck of the case. This insert is contained in a spring-loaded tool head that rides on a linear bearing. The Micro-Adjust Trimmer can be used in three ways.
First, you can secure the case in a PMA caseholder chucked in a power drill, drill press, or lathe. You hold the trimming tool with your hand and feed in the spinning case. (This method is handy because if you leave the case in the holder, after you have trimmed to length, you can switch tools and chamfer the case-mouth using the same power source).
In the second method, the trimmer’s adjustment knob is removed (after locking the setting) and the cutting shaft is chucked in a drill, drill press. or lathe. Using this method, the case itself is held by hand and fed into the cutter. Lastly, the trimmer can be used manually, holding the case in one hand and the trimmer in the other. That’s the slowest method, but it works if you do not have power tools handy.

Rifle accuracy and precision have come a long way in the past 15 years. The most recent tool to significantly improve precision is the barrel tuning system. The Rifle Accuracy System (RAS) developed by Precision Rifle Systems, LLC of Myakka City, Florida, brings a fresh approach to tuning. The RAS incorporates a precision muzzle brake with the tuner.
This system provides significant precision improvements and was the subject of a June 2012 Precision Shooting (PS) magazine article, titled “Improved Rifle Accuracy” and will also be featured in an article in the November 2012 issue of PS titled “Tuning with Confidence”.
READ MORE about RAS Tuner Tests on .260 AI, .223 Rem, and 22LR rimfire rifles.
Copies of both articles and detailed instructions on RAS installation and tuning can be downloaded from www.bostromgunsmithing.com. Eric Bostrom is the distributor for the RAS.
Accuracy is the ability of a firearm to hit what it is aimed at within the limits of the precision of that firearm. Precision is the ability of a firearm to place successive shots in or near the first shot. A firearm that delivers one minute of angle (1 MOA) precision should, at 100 yards, place the bullet within roughly one inch of where it is aimed (actually 1.047″), or a sight adjustment should correct the problem. All the improvements in optics, manufacturing and components have allowed precision expectations to go from 1 MOA to 1/2 MOA or even sub-quarter-MOA.
What is the next frontier for the precision rifle? While all the other advancements were being made, advancements in the understanding and methods of managing the barrel vibrations were also being made. Once the rifle has been built and the loads developed, it is the management of the barrel vibrations that has the final influence on the bullet as it is leaving the barrel and the final influence on precision. The RAS has demonstrated with many different rifles and calibers that significant improvements can be made with a properly tuned barrel tuner system. What does this mean? Typically, there is a noteworthy improvement. In fact group size improvements between 30% and 60% have been observed with a properly-tuned barrel tuner system. This has been demonstrated on both custom rifles and loads and factory rifles.
Jerry Schmidt, an avid shooter and hunter from Montana, has created a tool designed to help install single-dovetail or double-dovetail rings on hunting rifles. Jerry’s invention, the Scope-Tru Alignment Bar (patent pending), is unique. Unlike most other alignment systems, this is a single, long precision machined rod with a pointed forward end. You work on one ring at a time, first setting the front ring in the dovetail and then setting the rear ring. The process is shown by Jerry in the video below.
Jerry explains: “The Scope-Tru Alignment Bar is a tool designed to install both standard ring/mount systems, and dual dovetail ring/mount systems. The tool provides significant leverage to turn the dovetail rings into their bases. By observing the pointer on the end of the bar, it is easy to align the ring with the center of the barrel, thereby assuring that the ring is installed at 90 degrees to the axis of the bore. Because the bar is a one-piece tool, it is possible to get the rings into nearly perfect alignment with each other, and near perfect alignment with the bore axis.”
The photos above show how the tool is used to install and align a set of standard hunting rings (with rear windage adjustment). You start with the front ring, rotating it 90 degrees in the dovetail, and then align with the center of the barrel. Next, slide the tool rearwards and loosely set the rear ring in place. With both rings adjusted correctly, the alignment tool will be perfectly centered and both rings with be subsequently squared at 90° to the bore axis. Schmidt says he can install conventional rings with this tool, tighten them to spec on a rifle scope, and there will be virtually no marks on the scope tube. (Of course this would require that the rings are extremely well made with no burrs or highspots on the trailing and leading edges.)
The Scope-Tru Alignment Bar is CNC-machined from TGP bar stock, and will be offered in both 1 inch, and 30mm diameters. The durable bar is designed for regular, long-term use by the professional gunsmith, the home gunsmith or “gun crank”, and retail or wholesale sporting goods store staff. The 1″-diameter, all-steel Scope-Tru is can be purchased for $135.00 plus shipping and handling. The version for 30mm rings AND a new combo 1″/30mm Scope-Tru tool are both in final development, and could be available in the near future.

SIG P22X series handguns are justifiably respected for their accuracy, reliability, and build quality.* SIG Sauer has combined the features of its P228 9mm and P229 40sw pistols in a new high-capacity 9mm originally designed for Navy Aviators. SIG’s new M11-A1 is essentially a stainless slide P228 mated to a P229 anodized alloy frame. The wider P229 frame bumps capacity to 15-rounds of 9mm parabellum. The SIG M11 is issued to U.S. Naval Aviation and key units in other branches of the Armed Services. The new M11-A1 variant for civilians has been upgraded with a stainless steel slide, short-reset trigger, and 15-round flush-fit magazines. The M11-A1 features the same phosphate-coated internals, night sights, and MIL-STD UID label of the standard-issue M11. The M11-A1 should be available in gun stores this month. MSRP is $1125.00 while “street price” should settle under $900.00.
*This is not just hype. This Editor owns a German-made P226. It is very accurate and extraordinarily reliable. I’ve also owned some polymer-framed pistols over the years. They are gone now, and not missed. I will never part with my P226. I could tell you the round-count over the years without a single misfeed, FTE or stove-pipe, but you wouldn’t believe it. More reliable than a Glock? My personal P226 has proven to be just that….
