The golden age of polymer cased ammunition has probably already begun. Certainly, Norwegian-Finnish ammunition manufacturer Nammo seems to believe that, as they recently took a significant stake in American company MAC, LLC, makers of polymer-cased composite ammunition, some of which has already been type-classified by the United States Navy. MAC, LLC will continue as an independent company.  Nammo announced the acquisition via a press release, which is embedded below:

Inceptor Ammunition has introduced new cartridge offerings loaded with their ARX and SRR projectiles. Particularly, they now offer the defensive/frangible ARX bullets loaded into 10mm Auto and .450 Bushmaster rounds. The SRR bullets are now available for the .223 Remington and 7.62x39mm.

In March of 1963, a man named Lee Harvey Oswald purchased an M38 Carcano rifle and some quantity of ammunition from Klein’s Sporting Goods in Chicago. Oswald would later use this rifle and ammunition (or so the official narrative goes) to assassinate the then- President of the United States John F. Kennedy on November 22nd, 1963, in Dallas, Texas.

The United States Marine Corps has finally officially announced its adoption of the 5.56mm M855A1 EPR round, developed in the late 2000s by the US Army, marking an important step towards ammunition commonality between the two services. Until now, the USMC has officially only used the legacy M855 round, and to a more limited extent the SOCOM-developed Mk. 318 SOST round, refusing to adopt the US Army’s new M855A1. The Marine Corps Times reports that the Corps’ Combat Development Command has begun procuring the round for stockpiles, with its official adoption coming in 2018:

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?

Previously, we compared the Russian 9x39mm subsonic sniper round to its Western counterparts, including the .300 AAC Blackout and the .45 ACP. As it stands now, the 9x39mm is a subsonic round only – no supersonic loads exist for it currently. But… What if they did?

Idaho company Trom Technologies (formerly PNW Arms) is advertising a new .300 Blackout round that it claims extends that cartridge’s effective range to 900 meters, more than twice the generally accepted 400 meter value for that round. They claim the new round maintains a 100% chance of hitting an IDPA silhouette at that distance, and that it retains over 400 Joules of energy making it, they say, “effective on biological organisms of all kinds”. The company released a somewhat esoteric PDF that not only extolled the virtues of their new ammunition (which also comes in subsonic and .308 Winchester flavors), but details their corporate strategy of selling consumers “the subscription experience”. What this has to do with ammunition is not made clear in the file.

Today’s Modern Intermediate Calibers will handle something a little different. While virtually all rounds we have looked at so far were designed primarily for supersonic use, today we will be taking a gander at the Russian 9x39mm round – a dedicated suppressed caliber designed exclusively for the subsonic flight regime, with no supersonic option (yet) available. This begets a question, then: Is the 9x39mm truly an intermediate caliber? To answer this, we should consider a few facts about the 9×39: First, it was designed for carbines and rifles with cartridge overall lengths comparable to common intermediate calibers, like 5.56mm or 7.62×39. Second, it was designed to give substantially better performance than is possible with pistol rounds, including armor piercing effect above that which is normally possible with handgun rounds. Third, it is used more like an intermediate caliber than a pistol caliber, being issued with a whole host of sniper rifles, assault rifles, and other weapons comparable to any other intermediate caliber. Therefore, I would argue that it is an intermediate, albeit possibly the strangest one in common use.

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.

Sierra Bullets is a long time manufacturer of projectiles for the firearms industry. Some of its designs are legendary, and many shooters prefer its designs to any of the other options on the market.

Let’s start off with a question: What is the best round for the AR-15?

Advanced Shooting Products is a bullet manufacturer located in South Africa. They make both handgun and rifle bullets. Arguably the most interesting of their products are their defensive handgun bullets.

We are at a crossroads in small arms development. Demands for improved weapon effectiveness have reached their apex. At the same time, the soldier’s burden has grown into a crisis so pressing even the Army Chief of Staff has acknowledged it in testimony to Congress. Soon the next ammunition configuration will be decided, as new technologies open the door for a rethinking of the infantry’s most basic weapons.
