What You Need to Know About the [not so] New 224 Valkyrie

All about the .224 Valkyrie

Note: this article about the .224 Valkryie cartridge originally ran in May of 2018. With the continued release of specialized .224 loads, it seemed appropriate to republish it. 

There’s always a new cartridge out there. Some grow legs while others remain relegated to small communities of Wildcat enthusiasts. Meet the…

.224 Valkyrie

Earlier this year, the folks at Federal Ammunition announced the 224 Valkyrie. Its purpose in life is effective and accurate long-range shooting. What makes it different is that it fits into the same “gun form factor” as the pervasive .223 Remington. Let’s explain that.

224 vs 223

When I say form factor, I’m referring to the practical limitation – magazine dimensions. The well in AR-type lower receivers is only so big, so a cartridge that’s longer simply won’t fit and your rifle becomes a single-shot breech loader. The 224 Valkyrie, like the .223 Remington, uses a .224 diameter bullet but the brass case is different. The Valkyrie is based on the .30 Remington / 6.8 SPC cartridge. In fact, you can think of the Valkyrie as a necked-down 6.8 SPC. So, even though the bullet is the same diameter, you’ll need a 224 Valkyrie barrel due to the different chamber dimensions. You’ll also need a 6.8 SPC bolt although the upper receiver is the same.

Like the 6.8 SPC, the Valkyrie will expect a tweaked magazine made for the round since the geometry is different. So, the practical takeaway is to use 6.8 SPC magazines for your Valkyrie rifles even though the lower receiver and the corresponding magazine well are the same as any other .223 Remington rifle. You might get a .223 mag to work, but you also might find erratic feeding. Spend the extra few bucks and get the right ones.

Here’s why the Valkyrie is particularly interesting. While there are other great long-range cartridges available in larger AR-10 platforms, the 224 brings that type of range to the smaller AR-15 family. Standard loads range from 60 to 90-grain bullets, so the projectiles are heavier than most .223 Remington bullets, and since caliber is the same, the Valkyrie bullets are long and slippery. That means that they will carry velocity better over distance. That also helps with minimizing wind drift. So, the Valkyrie drops less and is less affected by wind.

Marketing materials claim that the .224 Valkyrie can stay supersonic to 1,300 yards. That’s true, at about 5,000 feet above sea level. Where I am, barely above sea level, it stays supersonic past 1,000 yards with ease. With no accuracy-killing super to subsonic transition until well past 1,000 yards, you have a predictable performance to four-digit yardage territory.

To put real numbers on that (considering average atmospheric conditions where I’m located) a 90-grain Valkyrie will drop 381.08 inches over 1,000 yards while a 55-grain .223 bullet will fall 452.99 inches. The difference in drift with a 10 mph crosswind between those two is 59.92 versus 101.5 inches respectively.


The Valkyrie is an interesting cartridge and I’m thinking it’s gonna catch on.

.224 Valkyrie ammunition

Hornady Black 75 gr. BTHP in .224 Valkyrie. Shooting Illustrated says it produces a muzzle velocity of 3,000 fps with about 1,500 foot-pounds of energy.

224 Valkyrie ammo

.224 Valkyrie is known for shooting flat to begin with: it’s possible the new 80.5 gr. Gold Medal Berger Hybrid and 78 gr Barnes Triple Shock X will improve upon that and stretch the cartridge’s legs even further.


Hornady ELD Match 88 gr .224 Valkyrie ammo

Hornady’s match grade 224 Valkyrie ammo is an 88 grain ELD Match bullet with a polymer tip: initial reports indicate the round performs better than other polymer tip ammunition (which often melts at high velocities).

    Honda had a new Valkyrie motorcycle for North American market back in the 1990s where it barely made it out of that decade before sales waned.

    There’s just too many unnecessary firearm calibers out there now. The Valkyrie may last about as long as the 300 blackout which, at least, was premised off an established 300 Whisper.

    Pretty cool though.

    • John L

      Why use 300 when we have cheep 762 x 39!

      • AR-PRO

        Its a hellova lot easier to suppress than 7.62×39!

        • John L

          Subsonic yes, there is more factory ammo available. The 39 case has more capacity. If I were really interested in subsonic I would use 45 acp 230 grain inherently subsonic and way cheaper to buy and shoot.

        • Wm

          not really, especially when you load your own.

  • Charles Edward Driggers

    Another caliber for people to buy a new gun that will eventually sit in there safe because they really have no use for it. Then they will try to sell it and nobody will buy it because all the hype has gone and no one wants it.. When will these companies learn.

    • John L

      You only need an upper? I have an unused receiver so barrel and bolt and I’m good to go, no 6.5 creed necessary!

      • Charles Edward Driggers

        So you will have an upper for sale.

        • John L

          LOL, sorry no sir. I have a receiver to put the barrel in and a left over lightweight handguard.

      sounds like charles has a safe full of bad decisions and assumes the rest of us do too. I do not. and while many like charles might buy this caliber knowing nothing about it, it is their own fault for not doing their homework 1st. but if you want long range distance from an AR15, this is an impressive round. easily ping’s steel at a mile away and not from a AR10 .308 cal. platform. people like charles fail to consider that we don’t all live in the city and limited to 100 yd. ranges. My closest gun range has a 600 yd. max.

      • Charles Edward Driggers

        Really? Are you in any place in the gun industry? Do not make assumptions about me or anyone else you do not know about. I have seen more calibers come and go than many and since the early 90’s this idea of making new cartridges every year has gotten out of hand. So you think I live in the city? How would you know? Like all the other variants for the AR 15 platform; there will be a push to buy ,then it will go flat. Bad decisions………..get real.

      • Wm

        sounds to me like Charles is being honest…You? I didn’t think so.

    • onfireinky

      Why would I get rid of it??? And why do you assume that the companies need to learn something??? Evidently YOU need to learn something. I only own four AR15 (should that be MSR?) calibers but have no plan to part with any of them.

  • Walter Williams

    Well, if I was to get a Valkyrie I would have to wait for a good brand of mag as ASC has always been a predictable disappointment.

  • Wm

    i have been shooting for over 57 years, and I served, have A CCW (48 yrs) and have been a professional trainer for 40 yrs…point is. I have seem my share of firearms and calibers come and go. While the long range shooting craze is the latest, it will also eventually die down. Any sport that utilizes technology over pure skill eventually goes the way of the dodo because the costs get out of hand. Say what you want..I have seen it happen. My grandfather was a PH and hunted all 4 Continents. He has taken virtually every game animal known to man, some that are now protected, and did it with two rifles. Both pre 64 model 70’s, one in 30-06, the other in .300 H&H…only in certain African countries was he required to use a .375 H&H due to their laws. Point is, the original long range orig. match, Wimbledon 1000yds, was won with a 300 H&H…no gizmos or ballistics tables on the phone etc..just needed too know how to shoot. I have read the comments from the wannabes who say they have never made a buying mistake, I say Bull sheet..you are just not man enough to admit it. I own three AR’s, and 2 AK’s…they are mostly useless unless you like burning up ammo for no good reason. If i did not have them it woul not bother me at all. If the govt becomes a tyrannical entity, my AR/AK wont make a difference, and neither will yours. I have many other rifles that I use for various shooting disciplines etc, including a custom Rem platform built by Badger, that shoots better than i will ever be capable of doing! It is in .308….works perfectly. If you really think that all the new calibers and firearms for them are necessary, then you probably think that no one will ever take away AR/AKs etc….and you would be wrong on both counts. The political climate will eventually make it untenable for AR/AKs etc and that is just a fact, like it or not., given time they done. In all my years of hunting my favorite rifles were a featherwight pre64 Win model 70 in .270 win. A Browning model 78 single shot in .270 win and a Ruger Mannlicher No1 in .257 rigby or 7×57 mauser….never had the need for more. I actually “hunted’ ,which required skill, knowledge and patience as well as marksmanship. We walked in, took hours, no vehicles, atvs etc.We took our deer, and walked out, dragging it with us!! I grew up in Penna., which did not allow semi auto for hunting…never saw anyone have a problem, and they harvest close to half a million deer annually in Penna. I hunted Wyoming with the .270 making shots to 400yrds or more at antelope because it was virtually impossible to stalk closer. I did not need any “wonder” cartridges to make clean kills on the game. Sp, you believe what you want, and keep telling yourself you need this firearm or that caliber, if it makes you feel good. But, please, do not try and tell me that any of it is necessary. It is just what you want to do, and that does not make it necessary, it just makes it what you want to do. period. The firearm manufacturers and ammo companies survive on that kind of flawed logic!!

    Why in heck would anyone want a rifle cartridge with bullet drop that drops almost 32 feet in 1000 yards? Read the article again. Here’s what the man said:

    “To put real numbers on that (considering average atmospheric conditions
    where I’m located) a 90-grain Valkyrie will drop 381.08 inches over
    1,000 yards while a 55-grain .223 bullet will fall 452.99 inches. The
    difference in drift with a 10 mph crosswind between those two is 59.92
    versus 101.5 inches respectively.”

    To WM, this bs won’t let me reply.
    My point is that some people like to shoot for FUN, remember FUN, everything is not a life altering decision. Why is it that people are so worried about what others spend their hard earned money on. It’s a hobby, everyone should have one. I’m tired of people judging what others do. If someone wants a .224 Valkyrie, by all means have fun, you may not be able to tomorrow.
