Next up for  the Big Freakin’ Cartridge Test is Federal’s T556TNB1 load, which is the civilian market name for the Mk.318 SOST projectile developed by US SOCOM as a “barrier blind” round for the M4 Carbine and Mk. 18 CQB upper receiver. This ammunition uses a reverse drawn jacket to improve accuracy, and couples a fragmenting front end with a solid gilding metal base that improves penetration through tough barriers. I love this ammunition, and use it religiously for home defense. The test procedure was as follows:

Next up for  the Big Freakin’ Cartridge Test is Korean manufacturer PMC’s clone of M855, called X-TAC M855 LAP. This ammunition features very uniform-looking external dimensions, attractively finished brass cases and projectile jackets, and a reasonable price. I formerly used M855 as a stockpiling round, although I have since switched to other rounds like Federal’s T556TNB1.

UTS Defense, known for their commercial pump action 12 gauge shotguns in the United States has featured a promotional image on the Turkish website ( not the U.S. one though) that shows a 5.56x45mm AR15 derivative titled the UT512 and a 9x19mm version titled UT9S. The promotion had the simple title of “Coming Soon” at the top, probably in time for SHOT 2018. It would appear that both of these designs have the intent of Military or LE application due to neither of them being legal in Turkey for civilian use, and both would at least be classified as SBRs if imported in the United States. Apart from a few different features, both weapons share the same handguard design, charging handles, BUIS sights, pistol grips, and similar but different telescoping stocks and flash hiders. Both appear to have ambidextrous magazine releases, in addition to what most likely are ambidextrous safety selectors. The handguard is very Midwest Industries-esque with the two bolts at the rear, gas tube vents, 

Taking drones down with so-called “soft measures” has so far been the fruit of most efforts to counter enemy UAVs. From using Picatinny rail mounted devices to interfere with signals to the enemy UAV, to using 40x53mm ammunition fired out of an automatic grenade launcher. An Israeli company called General Robotics has proposed a solution using conventional 7.62x51mm NATO M240s or 5.56x45mm NATO MGs in a Remote Weapon System setup. Essentially there isn’t anything new about what General Robotics is doing, really just applying existing technology to counter a new threat. The existing technology is their PITBULL remote weapons system turret that has been on the Military/LE market for at least a year. Below is a Youtube promotional video of the system.

Next up for  the Big Freakin’ Cartridge Test is Korean manufacturer PMC’s clone of M193 Ball, called XP193. This ammunition features very uniform-looking external dimensions, attractively finished brass cases and projectile jackets, and a reasonable price. Interestingly, XP193 appears to use a lower drag 55gr bullet, possibly based on the Sierra 55gr, instead of the somewhat draggier Remington-style projectiles used by Federal, IMI, and others for their M193 clones. I like to use XP193 when I need full-power ammunition without spending too much.  Continuing on from the last installment, we are now looking at the velocity test results for the 20″ barrel (more on the 16″ later).

The .224 Valkyrie may be the most interesting AR-15 round to come out in years, but the question many have been asking in my comments section is: Cool, but where are the rifles? Approaching the 2018 SHOT Show in Las Vegas Nevada, we are already starting to get answers, and one of them is the Savage MSR-15 Valkyrie. As the name suggests, this marks Savages first offering in the .224 Valkyrie round, and one of the first factory guns of this caliber.

Those eagerly awaiting the market for the new .224 Valkyrie round have something to celebrate. Gunmaker JP Enterprises recently announced that they are now offering three different barrels for the new cartridge, in 20″ light, 20″ medium, and 22″ medium contours. All three barrels use the somewhat unusual “extra long” gas system, which is two inches longer than the standard “rifle length” gas system normally used with 20″ barrels. The longer gas system coupled with large diameter port settings reportedly increase dwell time while reducing the port pressure. More details on the barrels are available via a review from Recoil.

Texas company True Velocity, LLC, has released the first images of their advanced lightweight polymer composite cased ammunition design via Instagram. Training company BAT Defense sent out an image of what appear to be 12.7×108, .50 BMG, and 5.56mm rounds made by True Velocity, saying that the ammunition was originally developed to reduce the weight of ammunition carried by light helicopters (such as Littlebirds).

If we can make a round that is significantly better than the existing 5.56mm or 7.62mm ammunition, shouldn’t the military just bite the bullet and switch, to the benefit of the servicemen and women in harm’s way? What’s stopping the powers that be from making the incremental improvements that everyone knows are possible?

Ammunition maker Federal Premium recently released its full bundle of press info on their new .224 Valkyrie round, coming on the heels of teasers released at Big 3 East. The .224 Valkyrie is a high performance .22 caliber round for the AR-15, which uses heavy, low drag bullets to dramatically improve the long range performance of the platform versus the .223 Remington and other rounds. This is the same principle that has been used in rounds like the .260 Remington and 6.5 Grendel for years, now finally applied to a factory .22 caliber round.

Portugal are about to embark on a major new small arms procurement programme. Jane’s reports that Request for Proposals for new infantry weapons will be issued soon.

At the 2017 Association of the United States Army annual meeting, gunmaker FB Radom was present at the Polish pavilion, displaying their MSBS modular assault rifle, recently named “Grot” (arrowhead) by the Polish government. The new rifle has been selected by the Polish government to replace their legacy AK fleet, many of which are the upgraded 5.56mm “Beryl” variant. The first order for the new rifles was signed in mid-September, and will result in the delivery of 53,000 rifles to the Polish government, which is expected to be completed by the end of November.

Rounding out our coverage of Machinegunapalooza 2017 – by which I mean the numerous machine guns of the 2017 Association of the United States Army annual meeting – we have the IWI Negev (5.56mm) and Negev NG-7 light machine guns. These Israeli belt feds are, among production weapons, some of the best-designed machine guns in existence today, incorporating the operating concept of the PKM into a weapon with light overall weight, exceptionally robust construction, and modern features. Also, unlike the PKM, the Negev is select-fire, with a semiautomatic fire setting in addition to fully automatic.
