.224 Valkyrie vs. 6.5 Grendel: The Ultimate Battle of 1,000 Yard AR-15s

U.S.A.-(Ammoland.com)- Your AR-15 is a ton of fun at close range. Punching holes in cardboard, demolishing milk jugs, pure semi-automatic joy as fast as you can take aim and pull the trigger. But you get no respect from the precision bolt-action rifle shooter at the range who says, “you can’t hunt with that thing anyway,” or “you can’t hit a barn door at 700 yards.” He throws you a smug look before settling in behind the wood stock of his prized bolt-action. When he fires, there’s a pause of silence, then “tink” as you hear the steel ring from THAT gong. The one you never even try to hit with your AR-15, the one that’s 1,000 yards away.

But, what if your AR-15 was capable of a one-shot takedown of game animals all the way up to the biggest mule deer in North America? What if your AR-15 could shoot in semi-automatic with sub-MOA accuracy to 1,000 yards and beyond? In 2018, you can! That precision bolt-action shooter is going to be annoyed when you’re ringing that 1,000-yard gong with your AR-15 three times faster than he can. But how?

6.5 Grendel – a Hunting Cartridge that Surprises Everyone

In 2004 Alexander Arms released the 6.5 Grendel, developed by putting a 6.5mm bullet into a necked down 7.62×39 casing. The 6.5 Grendel was designed for hunters to use on deer-sized animals out to 300-400 yards, beyond the effective range of any .223 Remington hunting ammo. The effectiveness at hunting was quickly overshadowed by Grendel’s surprising accuracy. Excellent sub-MOA (less than 1” spread at 100 yards) groups are easily obtainable. With the right barrel length and bullet combination, 6.5 Grendel is capable of supersonic flight past 1,200 yards.

.224 Valkyrie Takes Flight

.224 Valkyrie is the hot new caliber everyone is talking about. Federal Premium Ammunition released the Valkyrie in 2017, derived from a 6.8 SPC casing necked down to accept .224 caliber bullets. Valkyrie utilizes a smaller, lighter bullet than 6.5 Grendel, and it’s shape takes advantage of everything learned about bullet design in the 14 years since Grendel was released. Federal developed a new round that is twice as aerodynamically efficient as the 5.56 NATO round. The .224 Valkyrie boasts supersonic flight beyond 1,300 yards with less wind drift and drop than comparable rounds at the 1,000-yard milestone.

Let the Battle Begin!

The Primary Arms Battle E-mail Series takes you through side-by-side comparisons to help you choose which round is best for you. As we compare the two we have chosen several categories that will assist you on your buying decision.

Head to Head Ballistics

Bullets lose all chance of accuracy when they slow from supersonic to subsonic speed. The 6.5 Grendel and the .224 Valkyrie were designed to extend the range of the AR-15 beyond 1,000 yards. They each take a very different approach. The Grendel uses a heavier, longer, and fatter bullet measuring .264” in diameter that maintains supersonic flight past 1,200 yards. The Valkyrie uses a .224” diameter bullet that is longer and heavier than the .223 and stays supersonic past 1,300 yards.

Reading ballistics data isn’t for everyone, so we will keep it short and simple (ample data exists on each round and can be easily searched). Our discussion on the ballistics of the two rounds starts with their Ballistic Coefficient (BC). In layman’s terms, BC is a number that measures a bullet’s aerodynamics; for comparison purposes bigger numbers are better. Beyond BC, wind drift, bullet drop and terminal energy are all important factors in determining which is the better round.

Federal Premium Ammunition produced a study comparing different calibers of their Gold Medal ammunition.

* based on independent calculations

Long range ballistics are the Valkyrie’s song. With similar BC and outperforming 6.5 Grendel on wind drift and bullet drop, .224 Valkyrie takes a slight edge here. It’s easy to see, however, that both calibers leave even the best .223 Remington match grade bullets lagging. While the .224 Valkyrie appears to be more accurate based upon the ballistics chart, the success is countered by the heavier 6.5 Grendel’s delivery of nearly 40% more ft-lbs of energy at that distance. Which caliber is best for you will be determined by your use and ultimate requirements.

Winner: .224 Valkyrie

THE DEER HUNTER

If you want to hunt larger animals such as deer or mountain goats, 6.5 Grendel is for you. Make no mistake, 6.5 Grendel packs a wallop. At 300 yards it has more than double the kinetic energy of a .30-30 cartridge, and almost 4x the energy of a 75 grain .223 Remington hunting load. Because the bullet weighs so much more, Grendel doesn’t rely on velocity for its terminal effect on animals, so you don’t lose much effectiveness by choosing a 16” or 18” barrel. Grendel makes for a lightweight, handy hunting rifle that can be carried all day long and fired standing or from a hasty supported position. Valkyrie runs into a problem Grendel doesn’t have: many states have laws banning hunting medium to large game with .22 caliber cartridges of any kind, with no exceptions.

Winner: 6.5 Grendel

VARMINT VAPORIZERS

Almost all .224 Valkyrie barrels are 22-24” long to maximize velocity. Due to its smaller bore shooting a lighter bullet, .224 Valkyrie rifles exhibit much less recoil than 6.5 Grendel—up to half as much, depending on the loading. It’s no wonder that prairie dog hunters are anxious to try Valkyrie. 6.5 Grendel responds to the challenge by demonstrating its flexibility, with dedicated varmint loads available. Federal’s example features a 90 grain boat-tail hollow point bullet screaming out of the barrel at 3000 fps muzzle velocity. 6.5 Grendel is right at home when hunting hogs or coyotes.

Winner: Draw

THE 1000 YARD GONG

What if you aren’t hunting and you just want to ring that gong at 1,000 yards? Both calibers will get you there. Many shooters regularly take 6.5 Grendel to 1,000 successfully. However, .224 Valkyrie exhibits generally less bullet drop and wind drift than 6.5 Grendel, recoils less, and doesn’t cost more to set up or to shoot. It may not have much kinetic energy to spare at 1,000 yards, but Valkyrie flies better than any other cartridge developed for the AR-15.

Winner: .224 Valkyrie

Parts Availability, Conversions and Complications

With a 14-year head start on the market, there are more offerings of Grendel parts across a wider range of prices and configurations; .224 Valkyrie has a lot of catching up to do. At a minimum, both the Grendel and Valkyrie require a different bolt, barrel, and magazine when compared to a standard 5.56 NATO AR-15. Most enthusiasts choose to buy or assemble a dedicated complete upper in one caliber for easy interchangeability with their favorite AR-15 lower.

Safety Note: Choosing 6.5 Grendel comes with an added complication. There are “Type I” and “Type II” bolt/barrel specifications out there, and you CAN NOT mix and match parts for each of them without risk of damage and/or injury. Type II is by far the most popular configuration, but pay attention to what you are buying! A Type I bolt won’t chamber rounds in a Type II barrel at all. Even worse, a Type II bolt mated to a Type I barrel will create excessive headspace and result in a rifle that is dangerous to fire.

The magazine styles differ slightly, but both include shallow reinforcing ribs and modified followers. Grendel shooters benefit from years of magazine design refinement—6.5 Grendel mags are reliable, durable, and affordable. Valkyrie uses 6.8 SPC magazines which vary widely in price and quality.

Winner: 6.5 Grendel

FEEDING THE BEAST

Surprisingly, when it comes to match grade ammunition, the brand new .224 Valkyrie is not measurably more expensive than 6.5 Grendel. Match grade ammo prices for either caliber are pretty comparable to .308 Winchester. The bottom line is that quality match-grade ammo is more expensive than mil-spec or surplus 5.56 NATO, no matter which path you take. Expect to pay somewhere between $1.15 and $1.25 per shot for the good stuff. Range grade and plinking ammunition exists for both calibers at about $0.50 per shot.

Winner: Draw

TWO PATHS TO PERFECTION

A larger, heavier bullet, or a smaller, faster bullet? Those who prefer a proven system, want to hunt medium to large game, or demand a short, handy rifle will find a trusty friend in 6.5 Grendel. Shooters who like to shoot at long range targets, enjoy varmint hunting with a low recoiling rifle, and plan to shoot exclusively from supported positions should give .224 Valkyrie serious consideration. Let your own priorities be your guide—we’ll see you out on the range.

    1. One thing that is a huge factor – the Grendel has an overbore much lower than the .224 valkyrie. Barrel life will be 2-3x longer than the valkyrie

    2. With all these wildcats & mods on existing brass –

      Why does the Barnes 308-1.5 get so little attention ?

      Seems like the most natural cartridge in the world – 308 shortened 1/2 inch to fit in an AR15.

      More case capacity than 6.5 Grendel, 224 Valk, or anything EXCEPT 300 WSSM.

      And it uses 308 Brass !

      Who DOESN”T want a little more powder, and still fit in an AR15 platform ?

      Barnes 308-1.5 was set up for 30 cal. Could just as easily be necked down to 6.5 or 224 – with more case capacity than 6.5 Grendel or 224 Valkyrie.

      Given the prevalence of 308 brass, why is the Barnes 308-1.5 so under-appreciated ?

    3. For hog & deer hunting purposes— would be more interested in a “heads up” comparison of 6.5 Grendel Type II vs 6.8 SPC II. Any info on this ???

    4. these articles always make me laugh the 244 Valkyrie is loaded in a 22 inch barrel and uses a 90 grain .563 bc bullet which is one of the highest if not the highest bc bullets for the .224 cal bullet. And is said to beat the 6.5 Grendel but yet the Grendel is handicapped by using a 130 grain .569 bc bullet at 18 in barrel speeds, who writes this stuff. Lets run apples to apples how about a 24 inch barrel, 130 grain Nosler RDF at .615. still going 1447fps at 1000 yards real world measurement out of my gun. 244 Valkyrie is using a 90 grain .563 bc bullet at 2700 fps (as per their advertisement) means the Valkyrie is going 1376fps at 1000 yards (shooterscalculator). I know that my 6.5 does not drop below 1000fps out to 1300 yards so I am not sure where the guy in the article gets his numbers. and before you ask the real world numbers for my gun are measured by taking a sheet of AR500 cutting a 4 inch hole in it and placing it in front of my chronograph at whatever range I want to measure then shooting at the target, taking the measurements of the rounds that travel through the hole and over the chronograph. sighted in at 200 yards my Grendel drops 314 inches at 1000 yards (real world) the 244 Valkyrie will drop 326 inches (shooters calculator), the Grendel has a 72 inch drift in a 10 mph wind where the 244 Valkyrie will have a 80.6 inch drift in 10 mph cross wind. I think the 244 Valkyrie is a great round but Hodgdon reloading manual says 25 grains of cfe233 will get 2650 fps from the Valkyrie (close enough to the 2700 advertised by federal) from a 90 grain bullet in a 24 in barrel, I use 30.5 grains of cfe223, cci 41 primer, 2.34 OAL, 130 grain RDF to reach 2675 fps +/- 25 fps depending on outside air temperature. and can keep up .4 moa all day long. oh and as for the less recoil of the 244 Valkyrie over the Grendel, just put a good muzzle brake on the thing and watch your hits through the scope at 1000 yards, federal’s advertisement makes it sound like the Grendel is a punishing round to shoot… really… my daughter at 11 years old would shoot 200 to 300 rounds in one range day at 1000 yards with no loss of accuracy due to recoil…. as she likes to say “it is so easy to hit them (clay pigeons) that is almost gets boring…

      1. I also love the grendel for life. One of my favorites in a safe full of custom rifles. Im having one built on an older 700 adl still with the orgional walnut stock. This is without doubt my favorite for a new shooter, small woman. I also have a tikka creedmoor varmint, and custom gun werks 6.5 prc. I do believe if my house was on fire and i only had time to save one gun it would be the grendel.

    5. No one mentioning the 130 grain Grendel against the 90 Valk?? Hmm, that stinks, figures don’t lie but liars sure can figure. Let’s get some apples to watermelons comparison or would the drift and drop comparison not look so in favor of the Valk if both were putting 90’s downrange with equal length and twist barrels. Me thinks we would see more comparison in end ballistics,although I don’t have the data at hand to corroborate my hypothesis. Anybody out there have some data to help? Btw, the heaviest I’ve shot is 123 gn Hornady from my Alexander Arms 24″ Overwatch. SWEET!

    6. If you run out of grendel brass you can make them out of the 39 brass. With a good set of dies like Hornady you can even swedge the steelcased 39.s down to 6.5
      Bn shooting 7.62X39 afew yrs and going to get a grendel barrel for my AR soon i hope

      1. Try shot forming the 39 brass. A number of local reloaders have had good success getting good cheap Grendel Brad off the range.

    7. so… 224 scores two wins for the same stats (wind drift and drop)? let me explore the stats a little further here..

      drop and drift are measured in the same units and can be described as a right angle triangle, the long side of which represents the deviation to point-of-aim. now lets see how that bears out with FEDERALS OWN NUMBERS (conflict of interest is obvious, but let’s give them the benefit of the doubt)

      224 deviates 402.39 inches. Grendel deviates 518.73 inches.

      This is a big difference, and valk really shines! it’s a bit more than 25% more accurate, and that’s really significant!
      but lets be real here, you can compensate for drift and drop. YOU CAN’T MAKE YOUR BULLET HIT HARDER WITH HOLDOVER.

      So be that what it is, what valk will always have over grendel is that you can reach further and expect to get on target sooner. There no taking that away from valk. IT OWNS IT. So WHY WHY WHY does this article suffer the same mortal sin as all the other BOUGHT and PAIDFOR gush pieces written in the roll out of .224 valk by again overselling the product??? this cartridge can stand on it’s own merit! it doesn’t need to be as oversold as it is. And when you give it two wins for the same deviation stats, you over sell it JUST LIKE FEDERAL ASKED.

      So this brings us to a new point.. The numbers.. We gave federal the benefit of the doubt before with the numbers, but do they deserve that benefit when time and again on articles like these and on youtube videos we see .224 being oversold. again and again and again to the point where it becomes so painfully obvious that federal is involved with the messaging that it stinks of dishonesty.

      the proof is in the pudding. Valk is more accurate. 25% more accurate? I don’t know..I’m willing to believe truth can come from the mouths of liars.. But don’t be surprised if the truth doesn’t stack up to the hype as time rolls on..

      Or perhaps the truth is already catching up to the cartridge…

      1. I’ve been shooting the Grendel for 8+ years . Been shooting the Valkyrie for a few months now. Mostly at 1000 yards.
        A lot of the Grendel velocities posted seem to be exaggerated compared to my experience.
        My last 200 + rounds at 1000 have averaged sub 3/4 moa with the Valkyrie. Grendel never showed as much potential. ( never shot it past 850 but it never did better than 1-1.5 moa-ish) I know this is just my experience with 2 guns but it’s what I have to work with and I’m going Valkyrie!

    8. 14 years of bullet design since the Grendel was developed? Seriously? The Ballistic Coefficient and Sectional Density of long skinny bullets has been known since long before WWII. I have been hunting with a 6.5×55 SE Gustav Mauser for well over 30 years. The 6.5 Grendel was developed as a much more effective caliber than the 5.56/.233. Incidentally the .223/5.56×45 has never been a suitable caliber for hunting deer. That of course will bring a plethora of responses defending their ARs. I do have a Howa 1500 Mini Action 6.5 Grendel set up similarly to Jeff Cooper’s Scout Rifle but most often when I go out on opening day of deer season I take my old Marlin 336. 30-30. So far since living here. I have been in the woods 5 seasons. I brought home whitetails. All one shot kills all died within 20 yards. Anyway, the 224 Valkyrie does not mean the death of the 6.5 Grendel. It just means that AR lovers now have a more suitable round for those that love their ARs. Personally if I were to have a 223/5.56 rifle it would be a Ruger Mini-14. I do not like the AR platform. Never have, never will. I will admit that the gas piston uppers offer a more reliable system than direct infringement. Still I do not like ARs. Some of it has to do with the lousy politics of the Pentagon and arms manufacturers. I’ve been shooting since the early 1950’s and hunting whitetails since 1960. Hunting with tiny 22 caliber rifles is not humane. I don’t care what response is offered either.

      1. I took one of my .223 out for deer season many years ago. Took a solid shot on a nice buck. First and only deer I ever lost in 40 years of hunting, and that includes with bow. I know the shot was solid, but the deer ducked into thick knee crawler pines and there was so little blood that we lost the trail in about 20 yards. Before and since I always took out either the 336 .35 or the favorite since 1989, my trusty never adjusted Rem 700 BDL .270.

        I am looking however for something to put under mt ATN Night Sight for Coyotes and other critters that size and smaller out to 350 yards.

    9. Is there much of a difference between 6.5 Grendel and 6.5 Creedmore? Have always been a 308 guy so this is new territory.

        1. You’re kidding right?…! .223/5.56mm has 9x the energy of .22LR at muzzle . 22LR drops aprioximately 5 inches at 100yds where .223 is about an inch high. .223/5.56 also still has 9x the energy of .22 rim fire at 100yds as well. Unless you’ve never fired .223/5.56mm or you’re on drugs, it should be clearly evident that the only similarity between .22LR and .223/5.56mm is a .224 diameter bullet.

          1. Eric, Re-read Xaddo’s response to John here… Xaddo was referring to how much more difference there is between 22LR & 223 rem, as compared to 6.5 Grendel & 6.5 Creedmoor in John’s question.
            AKA Grendel vs Creedmore is not as much different than 22LR vs 223rem.

      1. Yup. The Creedmoor is a shell fired out of a 308 length magazine while the Grendel is out of a 223 AR sized magazine. The 6.5 CREEDMORE is a very accurate round and can be built using an AR 10 lower and the Grendel can be made br rebarreling your AR 15 and replacing the bcg with one for the Grendel case

    10. Have been a fan of the 6.5’s for ten years (DPMS 260LR), and wanted a Grendel since it came out. Unfortunately, kids college educations, transportation, etc,etc have put a crimp on firearm expansion. However, a couple of weeks ago, Primary Arms ran a special on a 20″ fluted barrel and bolt, so I picked it up. At the price I will be able to get into the Grendel Club for around a couple of bills. Have a busy summer, but plan on getting set up this fall to see if it can do at 1000yds what the 260 can (with 2/3 the weight and less recoil-hey, getting older, lazy and softer)
      PS: Thanks for the deal, Primary.

    11. I couldn’t decide which of these calibers I wanted. So I did what any good gun guy does… I just built both! I haven’t shot either one yet because I can’t get to the range for a couple weeks, but I have the 6.5 Grendel running through a 20″ Ballistic Advantage fluted barrel. I will be sending the .224 Valkyrie through a 24″ barrel I picked up at Brownells. I wanted a BA barrel for the Valkyrie as well but didn’t want to wait until they came out with something longer than 18″ and Brownells was the only one I could actually find that wasn’t sold out… though I think it was shortly after I bought mine. Might be back in stock now.

      Excited to try both of them. Grendel is going to be my hunting gun. Valkyrie will likely do a bit of hunting too, maybe some deer and coyote since a 90 grain bullet is plenty… but the Valkyrie will most often be with me at the distance range.

    12. 6.5 Grendel type 1 for my AR. I can use the same bolt as my 7.62×39 Windham Weaponry AR. Just swap uppers and rock on!

    13. My upcoming build is going to be the Valkyrie with a 20″ barrel. Been doing my research. AWESOME caliber and ballistics.

    14. 6.5 G suits me best. I like the fact that I can run both AR and bolt gun with same mags (Ruger American Predator). The Grendel just had a bad start and the issues with Type I and Type II make it less popular for the average shooter.

      Grendel still rings the same gong as the Valkyrie with a little more thought, but also with much more authority. For all around work in AR platform especially, Grendel is very hard to pass up, but then I look to do more than paper punching and steel.

    15. I bought a box of rounds for deer season , got home opened the box ,not 1or 2 or 3 but all 20 rounds had case damage. Went back to show and was told all ammo sales or finial. Wish i took pictures now. Been 3 yrs sence that eat shit day havnet been back sence….

    16. For range plinking on your ‘non-1000Y steel challenge’ days you can shoot your Grendel cheaply with Wolf 100gr FMJ at 0.24/rd (SPG-500ct, 119.69 w/free shipping code). 🙂

      I’m looking forward to trying out a good Valk setup. Ballistic Advantage has barrels in their Premium series (my preferred build barrel), but only at 18″ currently. I have assembled Grendel uppers in 16″ and 20″, but I’d really like a longer barrel for a Valk setup.

      1. Mic.I did my Grendel build last summer.This is a great weapon for both.I shoot 600 yd steel with no problem and took my buck at 280yds one shot dropped in his track’s
        Can’t say enough about the 6.5

        1. I use both my 16″ Grendel and a 7.62×39 upper for Peccary hunting in AZ. The x39 has been used for many years, with a transition to the Grendel a few years ago. Don’t often get long shots where we are hunting due to ground cover and terrain, however on the few occasions that a good longer-range shot has presented itself, drilling a spiky pig in a kill-zone is nicely done with the Grendel. (and will definitely penetrate their really thick skulls)
