Wilson Combat has come up with a new cartridge, dubbed the 7.62×40 WT (Wilson Tactical). Basically it is a .223 Remington necked up to .308 caliber, i.e. a .30-.223 Rem Wildcat. The cartridge is designed to give .30-cal capability to a standard AR15, using the normal bolt assembly and standard AR15 magazines. An AR15 can be converted to shoot the 7.62×40 WT with just a barrel swap. Note: Don’t confuse this new cartridge with the 7.62×39, the Eastern Bloc military cartridge that has been around for decades. The 7.62×40 WT is not derived from the 7.62×39 in any way. The 7.62×39 has a larger rim size, more body taper, and requires a different magazine and bolt. There have been 7.62×39 adaptations for ARs, but most didn’t function well (usually because of magazine issues). Wilson Combat claims the 7.62×40 WT offers the hitting power of the 7.62×39, but with a cartridge design that feeds and functions 100% in an AR15.
The 7.62×40 WT was designed around an optimal overall cartridge length of 2.250” which is a perfect fit for standard AR mags without shoving the bullet too far down in the case. Wilson says that its 7.62×40 WT barrels are optimally throated for the 2.250″ COAL. Therefore, Wilson claims, the “7.62×40 WT does not suffer from the same inconsistent accuracy issues in the AR platform often seen with the 300 Whisper and 300 BLACKOUT.”
Here are comparative Velocity and Energy numbers for the 7.62×40 WT vs. other cartridges with which it will compete.
7.62×40 WT (16″ Barrel)
110 gr: 2450 FPS Muzzle Velocity and 1466 Foot Pounds of Energy
125 gr: 2400 FPS Muzzle Velocity and 1599 Foot Pounds of Energy
150 gr: 2200 FPS Muzzle Velocity and 1612 Foot Pounds of Energy
5.56 NATO (.223 Rem) (16″ Barrel)
55 gr: 3150 FPS Muzzle Velocity and 1212 Foot Pounds of Energy
62 gr: 3000 FPS Muzzle Velocity and 1239 Foot Pounds of Energy
77 gr: 2750 FPS Muzzle Velocity and 1293 Foot Pounds of Energy
7.62×39 (16″ Barrel)
123 gr: 2320 FPS Muzzle Velocity and 1470 Foot Pounds of Energy
6.8 SPC (16″ Barrel)
110 gr: 2550 FPS Muzzle Velocity and 1594 Foot Pounds of Energy
At first it looks like the 7.62×40 WT has more energy than a 7.62×39 and outruns a 6.8 SPC handily. But Wilson omitted some key data for the 7.62×39. Taking load info straight from the Hodgdon Reloading Center, a 7.62×39 can be loaded to 2408 fps with a 125gr bullet, or to 2192 fps with a 150gr bullet at relatively moderate pressures (under 41,000 CUP, or roughly 44,250 psi). A 7.62×39 launching 150-grainers at 2192 fps generates 1601 foot-pounds, virtually the same as Wilson’s 150gr load. So, the 7.62×40 WT has no real advantage (over the 7.62×39).
Is This Cartridge Needed at All?
The “T” in 7.62×40 WT stands for “Tactical”, but we don’t think many police or military units will adopt this round. The 5.56x45mm is too well-established in the AR15/M16 platform and the 7.62×39 is the smart .30-Cal choice for an AK. So what, then, is the real “niche” for the 7.62×40 WT?
We think this round may prove popular with hunters who want to shoot a much heavier bullet out of a standard AR. A 150gr projectile is nearly twice as heavy as the biggest projectile you can shoot from a .223 Rem AR. The bigger bullet should work better on some kinds of game. Wilson Combat says: “Designed for tactical/defense applications as well as hunting for medium-sized game such as deer and feral hogs. For hunting the 7.62×40 WT vastly out performs the 5.56 and is on par with the 6.8 SPC at ranges out to 175-200 yards. The VERY mild recoil of the 7.62×40 WT also makes it ideal for female and younger shooters as well as anyone that’s recoil sensitive.”
Wilson says the 7.62×40 has proven itself as a good hunting cartridge: “A LOT of Texas feral hogs, whitetail deer and predators lost their lives testing the terminal performance of this cartridge! The 7.62×40 WT has proven to be a VERY efficient killer on medium sized game with the 110gr Barnes TTSX, 125gr Nosler Ballistic Hunter and the 125gr Sierra Pro Hunter. Any of these three bullets perform admirably on deer and hogs under 150 lbs. or so, but we recommend the 110gr Barnes TTSX for large hogs. The 110gr Sierra HP is a great bullet in the 7.62×40 WT for varmints and predators, and has proven to be one of the most accurate bullets.”
For home defense, it could be argued that the 7.62×40 WT is better than the .223 Rem because the larger, slower .30-Cal projectile has less penetration (through walls), but that would have to be demonstrated with real-world testing. Moreover, there are frangible .224-cal bullets that minimize the risk of over-penetration indoors.
Some benchresters might even tinker with the 7.62×40 WT in a bolt gun for score competition, but we doubt it would prove competitive with the 30 BR which can push a 120gr bullet at around 3000 fps. Wilson’s cartridge does give a paper-puncher the ability to shoot a .30-caliber bullet from a rifle with a .223 bolt face, and that might be attractive to club shooters in informal score matches.
Wilson Combat will be selling 7.62×40 WT loaded ammunition (with 110gr or 125gr bullets), but it is also supporting the reloading market. Wilson offers 7.62×40 WT brass, Hornady 7.62×40 WT dies, and you’ll find extensive load data on the Wilson Combat website. For those who want to put together a 7.62×40 WT AR, Wilson offers pre-chambered 7.62×40 WT barrels, as well as complete 7.62×40 WT uppers. Barrels start at $249.95, while the 7.62×40 WT uppers retail for $1024.95.
A dedicated iPad version of Ballistic (‘Ballistic’ App), a full-featured ballistics calculator for the iPhone, is available for the growing numbers of iPad users. As with the iPhone version, ‘Ballistic’ App for the iPad is “powered by JBM Ballistics” so it offers very precise solutions — typically, at 600 yards, JBM will get you within two or three clicks, provided you have good bullet BC data and reliable MV from your chronograph.
The ‘Ballistic’ App for the iPhone and iPad features a library of over 3,100 projectiles; the library includes the latest 2010 commercial data and G7 military coefficients from Aberdeen Proving Grounds. Along with calculating bullet trajectories, this software has many extra features. There are several different target cards so you can input shot placement and scoring is calculated automatically. There is also a range log (for recording shooting sessions), a mildot and MOA range estimator, and a convenient load database for storing your reloading recipes.
Special features in the iPad edition of ‘Ballistic’ App include: fully integrated split-screen ballistics, favorites, and range log; full-screen, hi-resolution charts; ballistics calculations update automatically as you edit; larger target sizes in range log; and screens can rotate. The iPad Ballistic App (release 2.3.7) costs $19.99. The standard version for iPhone and iTouch units, costs $9.99. To learn more about this software, visit ballistic.zdziarski.com.
The Drop Port is a great feature for benchrest shooters. You can run a bolt without an ejector, yet your cartridge will extract smoothly and reliably each time you pull the bolt back. Stiller’s Precision Firearms pioneered the Drop Port design, and Jerry Stiller offers this as a popular option with his Cobra, Viper, Python, D-Back, and Diamondback actions. The Drop Port is amazing in its simplicity (watch video below). As you pull the bolt rearwards, the fired case slides downward into a funnel. As it tilts nose-down, the case rotates free of the six-o’clock extractor, falls nose first down the funnel, and finally exits through a hole in the bottom of the stock. Gravity does all the work.
S&S Panda Drop Port Conversion
Until recently, if you wanted a Drop Port, your only option was to purchase a Stiller action or engineer a conversion yourself. Now the owners of Kelbly Panda actions can enjoy drop-port functionality via a conversion performed by S&S Precision Rifles in Texas. The folks at S&S will mill a slot in the bottom of your action, and then install a drop funnel in your stock. The conversion work is done so well you’d think the Pandas were originally made as Drop Ports by Kelbly. Drop Port conversions will be available for popular small match cartridges including 22 PPC, 6 PPC, 6mmBR, 6BRX, 6 Dasher, 6.5 Grendel, and 30 BR (plus other wildcats in the BR family).
Conversion Will Be Costly — New Actions Are Best Candidates
This conversion will not be cheap. Because Drop Ports require a six o’clock extractor, you’ll probably need a replacement bolt for your Panda. S&S is in discussion with Pacific Tool & Gauge to provide these bolts. You can probably resell your existing bolt, but the upfront conversion cost could approach $400 with new bolt and labor. S&S hopes to announce firm pricing in 4-6 weeks. Don “Stick” Starks, S&S’s lead gunsmith, also cautions that this conversion is most cost-effective with Panda actions that have not yet been installed, or which are set up with pillars (as opposed to glue-ins). Stick explained: “If your Panda is already glued in, then we have to remove the action, mill the port, install the funnel, and then re-bed the whole thing. That’s going to substantially increase your cost. It’s more logical to do this on a Panda that has not yet be put in a rifle.”
In the video above, you can watch S&S Precision convert a Stolle Panda action to a Drop Port, and then see how the converted Panda functions. The rifle is a 30BR owned by FORUM member Truckincars, who also created the video.
Ray Bowman of Precision Rifle & Tool LLC (PR&T) has a new stock design, the Low Boy Benchrest, that combines the successful features of PR&T’s F-Class stock with a rear end better suited to shooting from the bench. As you may know, PR&T’s F-Class stock, in the hands of Charles Ballard and others, has been hugely successful in F-Class competition. The new Low Boy Benchrest stock borrows the same low-profile front end, but it is different from the tang rearward.
While the Low Boy F-Class stock is designed so you wrap your thumb around (like holding a pistol), the Low Boy BR stock is designed so you can slip your hand along the side, with thumb rested lightly behind the tang, in a central position. Unlike the F-Class stock, which is designed for full grip “hard-holding”, this stock is designed for shooting with a “light hold” style (or even free recoil). These stocks are very straight dimensionally, so they track well.
We think this stock will work very well for 600-yard and 1000-yard Light Gun Benchrest competition. This Editor likes the stock enough that I am considering using a Low Boy Benchrest stock for a future Light Gun project with a Stiller Viper Drop-Port. The Low Boy BR stocks are affordable — starting at $330.00 for an un-inletted version with a 3″-wide fore-end. Inletting adds just $25.00 to the total. PR&T can also pillar-bed your action in the stock for an additional $225.00.
Handsome Bat-Action BRX in Low Boy BR Stock
The blue-stocked rifle in the photos belongs to FORUM member Bo W. (aka “Sighter”). It is a 6BRX with a BAT MB, multi-flat action. The finish and painting work on the PR&T Low Boy BR stock was done by Tuck. Sighter rates the stock highly, but he thinks the standard configuration sits a bit high in the back: “I like the stock and it tracks fine, but I feel the F-Class style height causes it to ride a bit higher in the bags than needed. I talked about this with Ray Bowman [PR&T owner] and have since ordered two more Low Boy BR stocks. With the last two, Ray cut about 3/4″ off the bottom of the stock butt and kept about a .67″ flat so a double-stitch bag will work. It is now more similar to a Tracker.” Shown below is a Low Boy BR stock with the reduced height option.
X-Treme Shooting Products now has its new Titanium Short Actions and Long Actions in production. Made from Grade 5 Ti-6Al-4V Titanium, these are the only custom Titanium actions currently manufactured in the USA. The long and short X-Treme Ti actions are available with +20 MOA Taper Titanium Picatinny Scope rails and Titanium Recoil Lugs. The .338 Actions will be coming soon, and will be offered with +20, +25, and +30 MOA Taper rails and integral recoil lugs.
We thought you’d enjoy some views of the short and long Ti actions, fitted in tactical rifles. Shown below is and X-Treme Titanium Short Action in the regular Accuracy International AICS 2.0 chassis stock. This rifle features a Krieger fluted barrel (chambered in .260 Rem), withe an X-Treme 2-stage trigger, and Nightforce 5.5-22×56 NXS scope.
The slide show below features the X-Treme Titanium Long Action in the new Accuracy International AX chassis stock. This impressive beast also has a Krieger barrel, but chambered for the 6.5×284 cartridge. The gun also has an X-Treme 2 stage trigger, and a Nightforce 5.5-22×56 NXS scope.

Mossberg has announced its new MVP (Mossberg Varmint Predator) line of dedicated varmint and predator bolt-action rifles, based on the Mossberg 4×4™ centerfire rifle. The big news is that Mossberg’s MVP rifles have a unique, patent-pending bolt design which allows them to reliably feed from AR15 magazines. Yes, we’ve been waiting for that functionality for a long time. Congrats to Mossberg for finally building a small bolt-gun that takes AR mags.
.
The first MVP Series Varminters were recently unveiled at the 2011 NRA Convention in Pittsburgh, PA. Two MVP versions will be offered initially. The first is a standard rifle with 10-round mag and factory-installed, Weaver-style bases. The second is a combo package which includes the rifle, 4-16x50mm scope (mounted), bipod, and 10-round magazine. Both guns have 24″ fluted, medium-contour barrels, with 1:9″ twist rates. MVP rifles will ship from the factory with sling swivel studs and factory-installed Weaver-style scope bases. Without scope, the MVP varminter weighs roughly 7.25 pounds. Mossberg claims its MVP rifles can deliver “MOA accuracy right from the box!”. We’ll see…
MVP Rifles Feature Adjustable Triggers
MVP rifles are fitted with Mossberg’s LBA “Lightning” Adjustable Trigger System, which adjusts from 2 to 7 lbs. pull weight. The LBA trigger, like the Savage Accutrigger, features a central blade that blocks sear movement unless fully depressed.
Nice Laminated Stock with Wide Fore-End
One of the best features of the MVP rifles is the stock, which comes with factory-fitted pillars. Mossberg fitted the MVPs with a nice, laminated stock that should work well either on sandbags or when shot from bipod. To ride the bags better, the fore-end is wider than typical hunting stocks, with a flat bottom. Stippling on the fore-end and pistol grip provide for positive hand placement. We think this stock is a pretty good design for the rifle’s intended uses.

OK, you .260 Rem shooters, break out your credit cards. The Lapua .260 Remington cartridge brass has finally arrived. Kevin Thomas of Lapua tells us: “Sorry for the wait guys, but it’s here. Grafs.com has its shipment and will begin shipping orders [May 4, 2011]. Kaltron Pettibone received theirs a few days ago and should be filling existing orders as I write. Let us know what you think of this stuff. Looks pretty good so far, but the proof’s in the pudding.” Grafs.com has the .260 Rem brass in stock at $96.99 per 100-ct box (Shipping included with $4.95 handling fee). Eabco.com has the .260 Rem brass in stock for $92.50 per 100-ct box.
The 6mmBRX (6BRX) is an outstanding cartridge that has set world records and harvested many trophies. Just last week Peter White used his 6BRX to win the NBRSA 600-yard Nationals convincingly. Peter loves his 6BRX, but he has one gripe — he must use two different dies to size his cases because a standard 6mmBR die won’t reach down far enough. White uses a .308 Win or .243 Win die to size the bottom of his 6BRX case then finishes up with his 6mmBR FL bushing die.
Redding 6BRX Dies Available Soon
Now 6BRX shooters have a single-step solution — Redding 6BRX dies. Robert Whitley has commissioned a special run of Redding 6BRX dies. Robert will offer a Redding Type ‘S’ full-length sizing die that will size the whole case, with bushing control over the neck. What’s more, Redding 6BRX micrometer-top Comp Seaters will also be available. Robert, who runs 6mmAR.com, expects these special-order Redding 6BRX dies to arrive within a few weeks. This is a very limited run of 6BRX dies, and Redding is not currently selling them through other sources. So if you want a Redding 6BRX Type ‘S’ FL sizer or Comp Seater die, you’d better contact Robert soon. Order through:
6BRX Cartridge Basics
The 6BRX is a modified version of the 6mmBR Norma case. The 6BRX has the shoulder blown forward about 0.100″, but it retains the same 30° shoulder angle of the parent case, and the same sidewall angle. You can use “normal” 6mmBR dies for the 6BRX — that’s one of its appealing factors — but the 6mmBR full-length sizer will miss part of the bottom of the case down near the web.
To compensate for this, many 6BRX shooters full-length size their brass first with a .308 Win or .243 Win FL Die, and then switch to a 6BR die. That system works, but it creates unnecessary steps. With a dedicated 6BRX sizing die, you can size the whole case in one pass, so you don’t need to use two dies. The $89.95 Redding Type ‘S’ Full-length bushing die sold by Whitley is one-die sizing solution that works. Whitley will also offer a package of the 6BRX Type ‘S’ FL sizing die plus a Redding Comp Seater for $199.95. That gives you a complete set of dies for your 6BRX wildcat.
The PMA Neck Turning Tool, review by Danny Reever PMA Tool was founded by Matt Harris and Pat Reagin, two former employees of Fred Sinclair. They both worked their way through college working for and designing tools for Sinclair Int’l. They now have branched out on their own and are offering some unique tools for the reloader.
I, like many other shooters out there, would sooner take a beating than change the settings of my neck turner. Many shooters even go out and buy a separate neck turner for every caliber — just so they don’t have to adjust the settings. Most of you know what it’s like, you ruin half dozen cases (or more) getting your neck turner just right, and if you change it the chances of getting it back to where it was are practically nil. Let me be the first to tell you those days are over! Like many of you, I first saw the PMA Neck Turning Tool in an advertisement on this website’s home page. It’s hard to miss, blue anodized finish with the large PMA logo on the body.
PMA Tool Moves the Mandrel, Not the Cutter Tip From PMA’s website I learned that this turner does NOT use a coarse or fine drive screw to move the cutter towards or away from the mandrel. Nor does the PMA tool move the mandrel on an eccentric (another method of cutting depth control). The PMA tool does something very different. PMA’s Model A Neck Turning Tool simply adjusts by moving the mandrel toward or away from the stationary cutter with an 80 TPI drive screw with 60 indicating marks. Each mark moves the mandrel .0002″ (two ten-thousandths). I found, if you stop between the marks, .0001″ isn’t out of the question. It’s such a smart arrangement, I wondered “why didn’t anyone think of that before?”
Use PMA, 21st Century, or Sinclair Int’l Mandrels
My interest now piqued, I contacted Pat Reagin for one of the PMA tools. Pat suggested that I also use PMA’s stainless expander and turning mandrels since they have put a lot of effort to get them exactly right. I might mention that the 3/8 shank stainless or carbide mandrels from 21st Century or Sinclair Int’l will work also. PMA does have carbide turning mandrels in the works — a nice upgrade for those of you who turn lots of cases at one sitting. I personally didn’t encounter any unnecessary heat build-up with the stainless mandrels only turning 10-20 cases at a time. Considering that carbide mandrels run about $40.00 compared to $7.95 for stainless, it’s nice to save a couple of bucks when you can.
Cut-Depth Settings Can Be Dialed “Dead-On” (Even after Caliber Changes)
Upon receiving the PMA tool I immediately went to my reloading room to set it up for turning some culled .308 Lapua brass — to clean it up 75% for a no-turn chamber. I followed the directions included with the turner and it was a snap to set up. After turning a few of the .308s I made note of my setting and changed both mandrels to 6MM to turn some Lapua 6BR brass for my .269″-neck chamber. Again the change went smooth as silk and I was turning the 6BRs in no time for my preferred loaded neck diameter of .26730″. I then decided to take the leap of faith and change back to turning the .308s after making note of the 6BR setting. That worked, so I then again switched back again to the 6BR setting — again with success. I have gone back and forth (between calibers) numerous times in the last couple of weeks. Each time I easily returned to my caliber-specific settings and I did not ruin a single case in the process. Without sounding like I’m gushing here I must say this is the nicest neck turner that I have ever used. The adjustments are so easy and repeatable “Even a cave man can do it”!
If, like me, you absolutely hate setting up neck turners, for fear of losing your settings, you owe it to yourself to give the PMA Model A neck turner a try. I think you’ll be impressed. The PMA Neck Turning Tool costs $95.95, complete with one carbide cutter with your choice of 30° or 40° shoulder angle.
