True Velocity and Sierra Bullets have partnered to introduce composite cased commercial ammunition that should be available in 2020. The cartridges will be composed of True Velocity’s steel-base polymer cases loaded with Sierra bullets. This ammunition will be initially available in .308 Winchester with more caliber options such as 6.5mm Creedmoor to be added in the future.

The first round up of the Big Freakin’ Cartridge Test is IMI’s take on the Black Hill’s classic heavy precision load, Mk. 262. Branded as “77gr Razor Core”, IMI’s version sports annealed 5.56mm NATO cases, neck and primer sealant, and of course 77gr Open Tip Match projectiles. Continuing on from the first installment, we are now looking at the velocity test results for the 16.1″ and 20″ barrels. The test procedure was as follows:

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.

The first round up for the Big Freakin’ Cartridge Test is IMI’s take on the Black Hill’s classic heavy precision load, Mk. 262. Branded as “77gr Razor Core”, IMI’s version sports annealed 5.56mm NATO cases, neck and primer sealant, and of course 77gr Open Tip Match projectiles. Based on reputation alone, I expected the best accuracy and relatively high muzzle velocities from this ammunition. The test procedure was as follows:

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.

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?

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.

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

Black Hills Ammunition released an improved version of their famous 77 grain long range precision 5.56mm round. The new version features a green color polymer ballistic tip Sierra boat-tail projectile calls the Tipped MatchKing (TMK). It’s the first ballistic tip bullet by Sierra bullet. Besides of the original Mk262 77 gr military load, Black Hills has been a long time user of the Sierra bullets in their ammo in various calibers.
