.224 Valkyrie AR-15 Introduced by Savage

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.

.224 VALKYRIE Barrels Released by JP Enterprises

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.

FIRST Military 6.5 Grendel Rifle? – 6.5mm Zastava M17 AK DMR in Testing by Serbian Army

Earlier this month, the Serbian Army debuted a new 6.5 Grendel weapon system, developed by Zastava. The rifle, called M17, is a heavily modified variant of the M70 AK family that has been developed by the company for decades. It incorporates a number of significant new features and improvements detailed below. The new rifle comes as part of an infantry upgrade for the Serbian Army which includes new 7.62x54R rifles, optics, helmets, and load-bearing equipment. This development marks the first adoption of the 6.5 Grendel round as standard by a national military force. The new rifle is advertised to be half a kilogram lighter than the previous rifle, although it’s not clear whether that is supposed to be the 7.62x39mm M70 or the 5.56x45mm M21. Reportedly, the rifles and the new caliber have not yet been adopted, but are still in testing.

The Home Team Advantage: Ammunition, Compatibility, and Why Change Is Bad

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?

.224 Valkyrie Will Get a 100gr Bullet – Federal Premium Releases Official Data and Loads

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.

The AR-15's Creedmoor? .224 Valkyrie vs. .22 Nosler and 6.5 Grendel (Modern Intermediate Calibers 025)

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

Are We Gearing Up to Lose the Next War? Overmatch, Part 2: Bullets & Backbreakers

In the rush to augment the infantry’s firepower with new advanced small arms technologies, we may be on the precipice of crippling their ability to fight wars. The push to equip the infantryman with more powerful rifles and machine guns risks reducing his mobility to critical levels, and “locking out” his capacity to carry powerful supporting arms. Although more potent basic infantry weapons are undeniably desirable, current attitudes towards their purpose – exemplified by the concept of “overmatch” – may compound problems that already have reached crisis levels.

New Redding Reloading Dies for 6.5 Grendel

What we writers have seen as an extended trend towards the “new” 6.5 calibers has indeed been a long-time coming just based on the sheer logic of the near ideal mix of weight, velocity, ballistic coefficient, barrel longevity, etc. While every caliber has its place, the 6.5 diameter round has had immense potential as an all-around cartridge – the holy grail of shooters.

Modern Personal Defense Weapon Calibers 009: The .22 Winchester Magnum Rimfire

So far in the Modern PDW Calibers series we’ve talked about small caliber, high velocity PDW rounds like the 5.7mm FN and 4.6mm HK, and we’ve tackled larger, punchier calibers like the 10mm Norma Auto and the 7.5mm FK. However, we still have not tackled the very extreme low end of the spectrum, that is rounds that are so small and impotent that many question their usefulness as antipersonnel rounds at all. However, small size brings with it some benefits in recoil and round weight, so it’s worth taking a closer look at this kind of round.

New .308 Based Cartridge – The 375 RAPTOR

Arne Brennan, arguably the real “brains” behind the 6.5 Grendel cartridge, has announced the release of his latest caliber, the 375 RAPTOR. Building on the knowledge gained from the 45 RAPTOR (an improvement over .458 SOCOM), the 375 RAPTOR is, in-short, is a shortened and necked-up .308 Winchester for the larger diameter “slicker” 375 diameter bullets.

Is Serbia the First Nation to Adopt the 6.5mm Grendel?

The 6.5 Grendel is in many military small arms enthusiasts’ eyes the ideal military caliber, in theory combining the best characteristics of both 7.62mm and 5.56mm rounds. However, in the thirteen years since the round’s introduction, it has found little if any traction with actual military users – until now. It seems that the Serbian government has quietly adopted the “slow and steady” six five earlier this summer. From Novosti Online:

BACK TO THE FUTURE? Textron Displays Newest Polymer-Cased Telescoped Firing Rifle

It looks like it could be back to the future for the US Army, if Textron’s new carbine design is any indication of what’s to come. The company unveiled its latest prototype of a cased, telescoped ammunition-firing rifle at Modern Day Marine 2016 in Quantico, VA, on Tuesday. The rifle, which weighs 8.7 pounds unloaded and feeds from a 20-round magazine, is reported to fire a 123gr 6.5mm bullet at 3,000 ft/s, producing 3,350 J and rivaling the existing 7.62 NATO in energy.

Modern Intermediate Calibers 021: The US Army Marksmanship Unit's .264 USA

We’ve discussed a lot of different rounds in this series so far, but today we’re going to discuss a round that actually has a shot of being adopted (at least in some form) by the United States military as a next-generation small arms ammunition configuration. That round is the .264 USA, developed over the past few years by the Army Marksmanship Unit (AMU).

Modern Intermediate Calibers 007: The .25-45 Sharps

On the heels of the 7.62x40mm WT, we are now going to take a look at another former wildcat based on the 5.56mm case, the .25-45 Sharps, a round I’ve discussed before. This .25 caliber round existed for years as the .25-223, a niche quarterbore caliber used mostly for predator hunting and similar rounds like John Wooters’ .25-222 Copperhead and Wayne Blackwell’s .25×47 have existed since the 1960s. However, the .25-45 Sharps is the first time the .25 caliber bore and the .222 Remington case family (in this case, .223 Remington) have been united in a factory offering, and one of the first .25 caliber rounds to be marketed to law enforcement and the tactical world, in addition to hunters. That makes it a candidate for this series, so let’s take a look at some ballistics:

Modern Intermediate Calibers 004: The 6.5 Grendel

One of the most ballistically interesting intermediate calibers ever developed is the 6.5 Grendel, developed by Arne Brennan with the assistance of Bill Alexander, and promoted heavily by the latter’s company, Alexander Arms. The 6.5 Grendel is interesting because it combines a wide case head based off the 7.62x39mm parent case with a short case length and ample room for long, slender bullets with low drag coefficients. As a result, the 6.5 Grendel is, very unusually for an intermediate caliber, well-designed for retaining energy at long distances.
