I do believe that if you fired both of them out of a 16 inch barrel the 6.8 special is going to have a higher muzzle velocity. However the 6.5 Grendel has a higher ballistic coefficient and sectional density so it will retain its velocity further. For inside of about 300 yd I would prefer to have the 6.8, but anything past that and I think the 6.5 Grendel is going to start having a serious advantage

This is true. Factory testing for the 6.5 Grendel is done on the 24" barrel. Factory testing for 6.8 SPC is done on a 16". This is what gives the box number discrepancy.

I have an 18" 6.5 Grendel and my tested velocity with handloaded 123 gr bullets is 2,491 fps. My handloads are loaded rather conservatively fr safety reasons, so I'm sure that they could be loaded hotter. Even so, that still keeps me supersonic to 1,100 yards. Dropping from 18" to 14" gave Alexander Arms a muzzle velocity of 2,400 fps with a 123 gr bullet. At 1,000 yards it's still going 1,189 fps. Just because the 6.5 Grendel makes maximum use of it's available power with a 24" barrel, doesn't mean it's ineffective with a shorter one.

22"-28" barreled rifles used to be the norm. 22" was considered short and started trending in the mid 20th Century for hunting rifles, especially Winchester's Featherweight series in the Model 70. A lot of surplus rifles had 24-28" barrels. Guys like my grandpa would re-barrel them with a sporter profile pipe in some other cartridge, a new stock, re-blue them, do trigger work, install bases and rings, and top them with glass. Brownell's really took off with that market for all the post-war gunsmithing that was popular in the US since we had such large imports of surplus rifles and healthy sales of domestic rifles. One thing that era didn't have was the ability to collapse the stock like on an AR15. If you wanted to, you could configure a 20-24" AR-15 in either of these cartridges and still have a relatively compact rifle. There are a lot of people shooting 12"-16" 6.8s and Grendels with 7"-9" cans on the ends of them. Subtract .625" of thread length and add the pipe plus suppressor and we're back to over 24" with the 16" barrel, but somehow those folks don't have any trouble carrying them on their hunts. I still went with the TBAC Ultra 5 on my 12" Grendel because I really do like a compact, lightweight set-up. I know a lot of people shooting 6.8 prefer 12.5" for the same reason. Others really like 20" for hunting. Choices, choices.. .

@@LRRPFco52 all true and good comment. They're not big here stateside but bullpup setups also give you a lot of barrel options while staying in an overall compact package. I'd love to add a Tavor 7 to the collection. I also would not want to run a can on a 24" AR. As you said that's a big part of the popularity of shorter barrels with many in use for hunting. 6.8 in particular was designed with that specific setup in mind (short barrel with can). I'm a 6.8 fan I'll admit it. I think it's a better hunting and combat round over 6.5 hands down. Both will do the job of course. 6.5 is a flatter flying round and that's why it's taken off in popularity but the real world trajectory performance of 2 identical AR builds with the only difference being 6.5 vs 6.8 are much closer than ppl realize, especially if shorter barrels are in use or if 6.8 is loaded to it's compression potential.

Long range shooting was not a priority, so I ended up choosing the 6.8 SPC. For real work applications, I still think it’s the best Jack-of-all-trades AR-15 platform. Well, I’m starting to get the long range bug and I originally looked at the Valkyrie since it uses the same magazines as the SPC. A friend of mine has a 20” Grendel and I really like it. I’m now leaning towards getting the Grendel over the 224 now. You are correct that it has a wider range of abilities once you incorporate the long distance. I just never thought I’d want to shoot past 400 yards. So why not have both? 😀 They are both equally impressive at what they do. As I’ve stated in another post.

I have both and mainly use for hunting. Most of my shots are less than 300 yards and swinging steel plate do not curb my hunger. I would question the velocity as it is posted to make sure the same barrel length is same. I can attest that shooting both, the 6.8 is easier to reload for and is more reliable. I like the 6.5 Grendel. But my reloads are finicky. Every thing has to be just right or will have functioning issues. Both are great to shoot out of the ar-15 (the barbie doll of Guns!)

High BC is more about retaining energy on target at distance, than it is about "flying flatter"

6.8 SPC, slightly larger bore with less powder, better for barrel life than 6.5 Gren. 6.8 better performance with wider range of powders than 6.5. 6.8 reaches velocity potential with shorter barrel than required for 6.5 to reach its potential. If you want long range precision, get a long range precision rifle and for that there are much much better 6.5mm such as 260 Remington and 6.5x55 Swede...also the 6.5 Creedwhatever (not a fan), but go ahead if you're into compromise.

The 6.8 actually has about 2 grains more case capacity than the 6.5 Grendel and operates at 58,700 psi vs 52,000 psi for the Grendel. The Grendel has a weaker bolt face because it has to be rebated out more to accept the case and as a result operates at lower pressure.

Love them both honestly. I will typically switch uppers or just bring both rifles to say deer camp if that's what the hunt at the time is and choose my caliber based on where I'll be hunting or what kind of hunting I'll be doing. If I'm being the ol brush dog flushing game up I'll take the 6.8, if I'm perched I'll take the grendel. Now honestly I've switched to .350 legend for the real thick brush because I live in the PNW, we get some extremely thick undergrowth. I've actually walked within 3ft of a huge bedded bull elk and had no idea, after I was out of earshot he popped up and walked into my dad.

Three HUGE FACTORS...application, weight of the firearm, and intended target. What application are these rounds used for? Application is important because it impacts what you will carry...in terms of barrel length. If you are sitting at a bench for long range shooting, then you don't mind a 20-24" barrel, as you won't be carrying a gun that weighs as much as the 308 AR-10 vary far...and this is where the 6.5 is designed at typically tested with. If however you are using the gun for hunting or self defense, you will want a lighter weight gun...and to get that weight reduction, you will remove 4-8" of barrel length, or possibly more...and end up with a 12-16" barrel...and when one does that, the 6.8 shines over the 6.5 grendel in terms of delivering energy ON TARGET out to 300 yards...as physics prove a larger bore diameters are more efficient transfer into a projectile in short barrels at any given bullet weight while IN THE BARREL...while thinner barrels capture less energy initial energy at any specific bullet weight (which is why they have longer barrels to make up for that loss), the smaller diameter bullets do tend to main their energy longer after LEAVING the barrel because of better ballistic coefficients. When using the SAME 12-16" barrel length and SAME weight bullet, the 6.8 has a higher muzzle velocity, although there comes a point where they meet...and for these two calibers the the cross over is around 300-400 yards. For these reasons, if one is using the gun for hunting or self defense, we have to consider gun weight distance to intended target. By "on target," we need to consider not just the speed of the bullet, but the actual energy transfer on target. And lets not overlook the fact that both rounds deliver insufficient energy to be an ethical choice for deer sized target beyond 400 yards. In a light weight gun used at ethical hunting ranges for these calibers, the 6.8 delivers more energy on target. If you want to shoot game over 300 yards, get a more powerful caliber round...and with the right platform then not only will you have more power, but you may still have a gun that weighs less than a 20-24" 6.5 Grendel. The 6.8 SPC also has better feeding reliability AND a stronger bolt. For me and my application of hunting and self defense within 300 yards in a light weight gun, the 6.8 SPC is the clear winner.

@garymyers4234

Using factory ammo the 6.8 is apx 100fp faster than the Grendel using the same weight bullet and same length barrel. Out to 175 yards the 6.8 has more energy with 110 and 120gr loads. A 16" 6.8 loaded with factory Hornady 120gr SSTs has enough velocity to expand and energy to take deer and hogs at 400yds. The Grendel horde likes to say the 6.8 is a short range hunting round and the Grendel is long range...BS. Load a 130gr Berger Classic Hunter (BC .497), 130 Speer or Sierra BT in the 6.8 and it will push it to the same velocity as a 123gr 6.5 Grendel. The BCs are very close so the drop and drift will be very close way past ethical hunting distances.

I caught that too, and I’m obviously a big proponent of 6.5 Grendel. That came off as biased against the 6.8 to me just from a technical standpoint, but I don’t think he meant to do that. I think he was just looking at published muzzle velocities without knowing that most box ammo mvs for Grendel are 24” barrels, whereas most 6.8 SPC data is for 16” barrels. What I found with 16” Grendel is that a lot of the velocities overlap, depending on the barrel and ammo combo, just like 6.8 SPC. There used to be some loads from SSA that were purposely loaded well beyond the SAAMI MAP that would shoot fast from tight chambers. Then some barrel makers started playing with more shallow rifling to get more velocity bump without pushing pressure. You can find the best comparisons from the same barrel shooting the same bullet weight. 6.5 Grendel 16” with 120-123gr does 2350-2480 depending on the barrel/load. I’ve had some 123gr Scenar factory ammo that did 2520fps from my 16” AA barrel, but I don’t list that since it isn’t representative of the vast majority of factory ammo. 6.8 SPC 16” barrel with 120gr Hornady SST factory ammo does 2460fps according to Hornady’s website. Other sources for ammo list their loads at 2450fps. Hand-loaders list most loads in the 2380-2520fps range, so you can cherry-pick the fastest from one and the slowest from the other with both of them to play that game, but they are so close that it looks pedantic to get wrapped up about it. The higher BC of the 123gr SST will actually retain energy better even at close range, so even if you start a bit slower, it surpasses the 6.8 120gr SST somewhere within 25-150yds. Both of them out-perform 7.62x39 for retained energy, and the Grendel shooting the exact same bullet weight from a 10.5”-12.5” barrel will smoke a full-length AK or SKS within 50-125yds. Frontal area of the 7.62x39 soft points gives you a good whack on-target though when you listen to them hit, but the actual energy from Grendel and 6.8 is more. The overall package to beat is a Grendel pistol or SBR. It does everything from close quarters HD/truck gun, to hunting medium game, to reaching out much farther than you would think.

I was still seeing Hornady 6.8 SPC American Gunner in the 200rd ammo cans up until midway into Kung flu, then it disappeared. I've occasionally seen 20rd boxes of 6.8 Hornady 110gr V-MAX or 120gr SST at Cabella's, but it's sporadic. I'm now seeing 6.8 PPU at 80 cents/round on ammoseek. Grendel flew off the shelves immediately and steel case went from 23 cents/round, to $2.00/round. I'm now seeing PPU Grendel for $1.45/round. Why is Grendel more than 6.8 from the same manufacturer after getting to US retailers? Demand I would look at your current inventory of brass and bullets to see if it surpasses a 500 piece count with each. Grafs has 120gr SST and 130gr Berger Classic Hunters in stock. If you don't hand load, look at your inventory of 6.8 factory ammo. For Grendel, the biggest practical advantage for shooters is/was steel case at 23cpr, until WuhanFlu. The next biggest practical advantage is that you get 175gr .308 trajectory from an AR-15 with half the recoil, and 85% of the energy on-target. If you're only limited to 500yds, it will depend on what region of the Nation you live in. Deep South or Northeast/dense trees with mostly close ranges, it won't matter much. Mountain West with wide open spaces, lots of wind? Grendel If you want to chase the Grendel with 6.8, and have a tighter twist barrel, that 130gr Berger Classic Hunter will do well if you hand-load. I have a boat load of Grendel brass and bullets, so I'm set until prices hopefully stabilize. Anything 6.5mm bullet component-wise gets sold immediately.

@P. Cameron What barrel length and twist rate are you using?

My best accuracy and hunting load has been the 6.5 129gr SST... I' getting the same 2550 fps +/- but the energy is substantially more than the 123gr. .5 MOA all day long. I can shoot the 107gr Sierra matchking at 100, and get smaller groups, but the wind plays a factor past 300. The 129gr SST doesn't seem to be as affected at 300-500 yards (the longest I've shot mine).

Lol as if the hogs could tell an ounce of difference between the two

I looked at both a few years ago with the goal of using one in a 16-18in upper to hunt deer out to 200-250. I picked the grendel because it edged out the 6.8 in most performance categories, but with the typical shots being well inside of 100, either one would have been fine. As others have said though, after 200 (if I ever needed to do it), the grendel starts to set itself aside and that’s not knocking the 6.8, it just wasn’t designed with that in mind.

What are the barrel lengths for the compared speed/energy? How about out of a 10" barrel?

I'm going for the 6.0 Grendel, er, the 6mmARC

Is the .224 Valkyrie a good combat round in your guys’s opinion, and why? Thanks

I'm a 6.8 spc fan but of course I like most calibers but 120gr 6.8 isnt actually that common at where I live, 90gr 110gr are what I see on shelves (well nothing at this point in time), even when ordering online I see more of the 110gr than 120gr.

Inside of 300 yards, there is not much difference at all. Past 300 yards the higher BC of the Grendel takes over. The 6.8 SPC was designed for a 16" barrel. I like the 6.8SPC for average deer hunting range use. I'm not needing to reach past 300 yards or care to and I like a 16" barrel in an AR platform for hunting use. It is easy to carry and use in that length.

Stats that show 6.5 Grendel as being faster for the same bullet weight, are not comparing the same length barrels. The opposite is true. Out to 300 yards the 6.8 is faster when both have a 16" barrel. The 6.8 has a slightly greater case capacity and a larger diameter surface area for the pressure to push on. With equal pressure, the SPC will have a higher MV. I own both. Have a 6.8 SPC in a 16" barrel and a 6.5 Grendel in a 24" barrel. When it comes to hunting Whitetails, I'll grab the SPC every time. Neither of these are powerful cartridges, so I would never fire over 300 yards with either of these. Probably much less. At that range neither cartridge has a significant advantage. I built the SPC to be a very lightweight hunter whereas the Grendel upper I purchased is very heavy to haul around the woods. Might as well go for an AR10. For long range target shooting or maybe varmint hunting, I would grab the Grendel.

I chose the 6.8 since I live in a heavily wooded area, I almost never see a target farther than 300 yards

Big fan of the Grendel!

I have a 6.5 Grendel and love it. Very accurate and much more power than a .223/5.56 with not much more recoil. Pleased with the JP Rifles match cryo barrel that I'm running this through. Better blood trail to find game when shot in the vitals than the .223/5.56 so more recovered game. I imagine the 6.8 SPC is about the same within 200 yards as mentioned below, but expect the 6.5G would edge it out further out (say 500+ yards). If I ever start reloading then the 6.5 G and my 6.5 Creedmoor use the same projectile which is a bonus. I am enjoying all of these AR-15 calibers coming to market like the 350 Legend, 224 Valkryie, etc. It is nice to have the variety in this lightweight platform. To me the one down side of the 6.5G is that the ammo is not cheap and that may be a consideration for the 6.5G ($24/box) vs 6.8 SPC ($ I'm unsure) debate. The other down side is you have to use 6.5G magazines and they are not that common and I have only found them in steel, but I think someone is starting to make polymer ones too. Really can't go wrong with either of these two cartridges.

I built a 6.8 SPC carbine last summer and burned my two buck tags with it this past season. Deadly with Win. Deer Season. Building a Grendel upper this summer in 20” to see how I like it.

I cannot load the Grendel faster. According to Hodgdon with 120 grain bullets for both, the fastest load for the Grendel is 2498 fps and the 6.8 is 2543 with a shorter barrel. The BC ABSOLUTELY favors the Grendel but no real difference at hunting distances. For example both sighted in at 100 the Grendel is -17.40 inches low at 300 and the 6.8 is -17.58. They are both great 250 and in hunting rounds. The Grendel is the better long range target load IMO.

I wouldn't. Unless all you need it for is long range. 6.8spc is actually a better round practically speaking for MOST PEOPLE. 6.5 grendal does great long range 300yards and out, but anything inside of 300yards, or anything with a barrel lengh less then 16 inches 6.8spc rules the day. And let me ask you are you really taking animals farther out then 300yrds? Self defense wise you are never gonna shoot at someone that far away because how could they be a threat? So unless your a competition bench rest shooter, or you live on a ranch or some thing for most people 6.8spc is a far superior round. Especially if you buy a lwrc six8 rifle to shoot it out of......notice he did not mention barrel lengh here, to get those numbers from grendal you need like a 22" barrel.

Can't go wrong with the Grendel. Cheap ammo available as well as match ammo. Great caliber!!!

Bolt strength. Much more likely to have lug failures with the Grendel and other cartridges that use the 220 Russian parent case. There is substantially more metal supporting the lugs on the 6.8 bolt which uses the 30 Remington as its parent case. My favorite AR gunsmith will not build a Grendel or 6mm ARC because of lug strength concerns. (White Oak Armament.) Have you ever reviewed the 6mm WOA round?

I was using the 6.8 spc in another country and was able to take out snidely whiplash behind a truck door at 300 meters plus it’s a piston not gas impingement

been looking to add one of these to my collection and hunt with would love to know the numbers on the same barrel length gun but what im hearing 6.8 spc is superior inside 400 yards and i dont shoot past 300 and i cant find grendel ammo but can find SPC

In 2015, I shot a small spike buck using a frontal shot at 30 yards, directly into the chest, with a Hornady V-Max in 6.8 SPC. The deer seemed only slightly distressed as it trotted towards me and I took a sidelong shot just behind the shoulder at 5 yards as it passed me. Only then did it drop to the ground and died when I walked up to it. I did find the first bullet in its chest and it was perfectly mushroomed out to 5/8" diameter. The second bullet passed through the rib cage and out the other side. I decided to go back to my .308 WIN after this. Unfortunately, I built 2 AR-15s for this cartridge before I shot this deer.

This video was made a while back but a big benefit of the 6.8 is that you can buy it lol. 6.5 Grendel seems to be out of stock everywhere with exception of $2+/round type sites

The Grendel is NOT "faster" at the muzzle when comparing the same barrel length, the 6.8 has a higher muzzle velocity when the barrel length is the same.

In the US the Swede is a great round IF you reload, otherwise I'd recommend going with the Creed because there's a LOT more ammo availability... If you're in Europe or elsewhere other than the US then there's a lot more ammo selection for the Swede.

Ham'r ain't going to catch on fast, parts are scarce and boutique right now, and it doesn't have nearly 20 years of history behind it. Or cheap ammo. And really, it offers very little if any advantages over a 6.5G or 6.8 SPC, and has a big downside in that it is far worse in shorter barrels than either of the other two. The upcoming 6.8 for the Army hasn't even been settled on...is it going to be a telescoping cartridge, or a steel/brass hybrid cartridge, or even caseless, nobody has decided yet. You can technically buy Sig's version now, for the Cross rifle, but that may not be what is selected.

The HAM'r is essentially a 7.62x40 spec II. It's about 75 fps faster bullet for bullet, but the longer case restricts the heavier bullets that have no problem loading in the x40 at magazine length. The 6.8 also has better BC than .30, comparing same bullet weights. The HAM'r has more energy at the muzzle, but the 6.8 will be moving faster past 100 yards. Past 150 it will have more energy too.

How come you didn’t mention Barrel lengths? The 6.5 is recommended to be used in a 20in or longer barrel in order to get those muzzle velocity advantages. I will take the 6.5 also but with a 20 inch barrel. I think the 6.8 would be better suited to compare against the 300 blackout. Which both are designed for shorter length barrels

Both do about the same thing at 300yds. Not a lot of difference. The Grendel really is a poor choice in a self loading rifle because its not a reliable case feed design while the 6.8 is excellent and was designed from the start with fighting reliability in mind first and formost, that is the reason it has some case taper to it. I always hear people yap about how superior the Grendel is, but its not always about the utmost in velocity or ballistic performance. Its more than just speed and energy and B.C. Case design for the weapon is a major consideration and its why I prefer the tapered and feed and extraction reliable case of the 6.8 in an AR rifle. Its simply a better design and even in 16" and shorter barrels its better than the Grendel. The Grendel thrives in the realm of 20" barrels and in this format is better than a 6.8 in performance. Now in a bolt rifle for certain the 6.5 Grendel is the choice all day, any day. Its perfect for bolt actions. So yeah, each has its own realm or reason for existing. Its more than just ballistics data and drop charts if you really look into it and no matter how you slice it neither the 6.5 Grendel nor 6.8spc are high performance long range or high energy cartridges. They're mid range 300yd performances and they do well in that role.

Geez, shocker! A 6.8 guy bashing the Grendel. But I gotta ask, do you own a Grendel? Most people who have at least one know they do just fine in a semiauto, ie a self loading rifle, like the AR & AK. _"its not a reliable case feed design"_ Funny you say that considering Bill Alexander has built full auto 6.5 Grendels that ran like a typewriter.** If it were as problematic as you imply, then why would the Serbians have adopted it for their M17 rifles? That's not something that happens if it has an unreliable case feed design, yeah? Feeding problems are more related to magazine issues. Many of those magazines marketed for the Grendel are just 6.8 SPC magazines masquerading as Grendel mags. In mags made for the Grendel, it's not an issue. As for case taper? The 6.5 Grendel has a nearly identical case taper to that of the 308. So are you also implying the 308 has problematic feed and extraction issues as well? _"~and shorter barrels its better than the Grendel."_ Many would disagree that the Grendel doesn't do well in short barrels. My 10.5", 12", 13" and 14.5" would concur. My 12" can boringly connect out to 600 yds. Last I checked initially the 120gn 6.8 SST from a 12.5 is what 50 to a 100fps faster than a 123gn Grendel SST from a 12"? I don't think that's enough to quibble over. But for the sake of argument, by 200 yds the Grendel begins to overtake 6.8. But as you said, _"Both do about the same thing at 300yds. "_ I agree any difference really isn't worth mentioning. I think the 6.8 SPC is a fine cartridge. It just doesn't interest me as much as the Grendel does. ** *_About 12 years ago I had the opportunity to handle and fire a 10.5 inch gun Bill Alexander brought to an industry event.

You know how many pounds of 6.5 Grendel brass I have through multiple different rifles, carbines, and pistols of the years without all these feeding issues? I’m not talking about little range sessions either, but hundreds of rounds fired per day over multiple days since 2009. Just did a high volume, 2-day/1-night CQM course where multiple guys brought 12”, 16”, and 18” Grendels, 12” and 16” suppressed. They burned through 2 cases of Grendel at least. No malfs. Every DM course and LR course I’ve run or coached, guys and gals end up with piles of brass around them. Don’t recall malfs. I have 22”, 18”, 18”, 17.6”, 16”, 12”, and 10.5” now. I really like the 18” and 12”. Still haven’t done the 10.5” yet. Grendel thrives in whatever barrel length you put it in. I haven’t shot the 22” in years. It’s a big bull barrel Lilja fluted, beautiful rifle in Seekins billet upper. It’s all funny because I only played around with Grendel initially as something maybe fun for shooting alongside .260 Rem, just to see what it would do. I wanted a 20”, but they sold out, then 18” sold out, so I was left with 16” or 24”, and I went 16”. I’m glad that happened because it allowed me to see what a Grendel would do from a barrel that “it wasn’t optimized for”.

The only that was true in this video was the 6.5 having the better BC. The 6.8 has more case capacity and better velocity with equal length barrels and bullet weights. Both are u see powered for game past 300 yards. The 6.8 feeds better. The 6.8 can run at about 3,000 pounds more pressure. The larger diameter bullet has more surface area for gas to push. There are vastly more high quality hunting bullets loaded commercially for the 6.8. The 6.5 crowd always toughest the long distance ability of the Grendel but it’s under powered for anything but paper at long range. The 6.8 is the superior round it’s just that the 6.5 ballistics get quoted from a 24” tube and the 6.8 gets its from a 16”

Using factory ammo the 6.8 is apx 100fp faster than the Grendel using the same weight bullet and same length barrel. Out to 175 yards the 6.8 has more energy with 110 and 120gr loads. A 16" 6.8 loaded with factory Hornady 120gr SSTs has enough velocity to expand and energy to take deer and hogs at 400yds. The Grendel horde likes to say the 6.8 is a short range hunting round and the Grendel is long range...BS. Load a 130gr Berger Classic Hunter (BC .497), 130 Speer or Sierra BT in the 6.8 and it will push it to the same velocity as a 123gr 6.5 Grendel. The BCs are very close so the drop and drift will be very close way past ethical hunting distances

Three HUGE FACTORS...application, weight of the firearm, and intended target. What application are these rounds used for? Application is important because it impacts what you will carry...in terms of barrel length. If you are sitting at a bench for long range shooting, then you don't mind a 20-24" barrel, as you won't be carrying a gun that weighs as much as the 308 AR-10 vary far...and this is where the 6.5 is designed at typically tested with. If however you are using the gun for hunting or self defense, you will want a lighter weight gun...and to get that weight reduction, you will remove 4-8" of barrel length, or possibly more...and end up with a 12-16" barrel...and when one does that, the 6.8 shines over the 6.5 grendel in terms of delivering energy ON TARGET out to 300 yards...as physics prove a larger bore diameters are more efficient transfer into a projectile in short barrels at any given bullet weight while IN THE BARREL...while thinner barrels capture less energy initial energy at any specific bullet weight (which is why they have longer barrels to make up for that loss), the smaller diameter bullets do tend to main their energy longer after LEAVING the barrel because of better ballistic coefficients. When using the SAME 12-16" barrel length and SAME weight bullet, the 6.8 has a higher muzzle velocity, although there comes a point where they meet...and for these two calibers the the cross over is around 300-400 yards. For these reasons, if one is using the gun for hunting or self defense, we have to consider gun weight distance to intended target. By "on target," we need to consider not just the speed of the bullet, but the actual energy transfer on target. And lets not overlook the fact that both rounds deliver insufficient energy to be an ethical choice for deer sized target beyond 400 yards. In a light weight gun used at ethical hunting ranges for these calibers, the 6.8 delivers more energy on target. If you want to shoot game over 300 yards, get a more powerful caliber round...and with the right platform then not only will you have more power, but you may still have a gun that weighs less than a 20-24" 6.5 Grendel. The 6.8 SPC also has better feeding reliability AND a stronger bolt. For me and my application of hunting and self defense within 300 yards in a light weight gun, the 6.8 SPC is the clear winner.

The math just isn’t there. They’re really close within 100-200yds, depending on what bullet you shoot. Some loads and rifles might have a little more velocity over the other, with overlap between the two cartridges that depends more on the barrel and ammo. Any advantages in speed with the 6.8 are overcome with BC within the first 100-150yds usually, and they’re so close already that it becomes academic at that point, nothing earth-shattering.

Much faster, less drop. Stays supersonic much further out.

Serbian army adopt 6.5 grendel and they made AK system rifle in that caliber with replaceable caliber with only changing barrel and magazines of the rifle with 7,62. Zastava M17, 6.5/7.62 interchangeable caliber.

So which would you recommend over the other for deer?

Can anyone tell me where all the factory 6.5G ammo has gone?

Its been said that 6.8 is better suited in short barrel configurations vs 6.5...IMO 6.5 has too much wasted energy in short barrels (shorter than 12")...the 6.5 excels in longer barrels

Can a 5.56 mag be used for 6.5 Grendel? Are the feed lips different? Is the follower any different? The 6.5 rounds go in the mag, but I have not attempted to try and operate my 6.5 Grendel AR with it.

P.S. i was also wondering if the 6.8 Western can be chambered in an AR15? lol

My 6.8 argument is that I found a home build at a gunshop on sale for like $400 a couple of years ago.

Some times the home builds use the best barrels.

I have two AR platform uppers in 7.62X39, I have never been able to get them to work reliably, I think it is mostly a magazine issue. What is the cheapest conversion? Could I change the barrel to a 6.5 Grendel and still use the same bolt?

No you would need a new bolt and barrel. Almost all Grendel bolt's are known as type 2. There used to be a type 1 that I believe it was a 7.62x39 but I dont think you could ever find a type 1 barrel anywhere.

How's barrel life on these cartridges? I like my 300 Blackout, but the 6.8 was a close competitor. I'm sure my Blackout will last practically forever, but I'm kinda curious about the other alternative AR cartridges. 6mm ARC, 6.8 SPC, and the 6.5 Grendal all seem like good options.

From everything I've read and searched, most calibers in the AR-15 have excellent barrel life. I maybe wrong on this, 5.56 has a chamber pressure of about 55-56k psi. 6.5 Grendel was designed with a 50-52k psi chamber pressure. From what I've personally seen in comments, people get Grendel and Creedmore confused. IMO, Grendel didn't really take off until Creedmore was launched. From what I've read, Grendel predates Creedmore by about 10 years. Be that as it may, Grendel will give as long a service life as 5.56. Which is better? You will have to decide. What do you need your rifle to do? Research costs time and thought.

Do you need a specific lower? Or can you use any lower and just buy a barrel/upper?

You forgot to mention the Grendel velocity came from an 8" longer barrel

Doesnt the muzzle velocity info on 6.5 grendal come from a 24 in barrel where the 6.8 SPC is using a 16 in barrel? Atleast the info printed on the box of ammunition. And wouldnt a longer barrel give the 6.8 more powder burn to help increase its muzzle velocity if comparing barrel lengths that are equal?

If you can find info on. 25 inch 7.62 r vs a 25 inch 5.56 barrel and find out how much it amplified the velocity to based on 16 inch for both being the control then we can solve that question. What I do know is that short shell case designs provide a very low reduction if velocity when the barrel is shortened to nothing. The 308 however loses a huge amount of velocity for every inch of barrel cut.

@Dubya1776

I have both and have been shooting the 6.8 for 7 years. Have taken deer with both and reload both. No real world difference in my opinion for hunting. And yes the published ballistics are BS because the Grendel is base lined with a 24” barrel and the 6.8 is base lined with a 16”. I have a 21” Stag barrel on my 6.8 and get over 2700 at the muzzle using 120gr bullets and 2850FPS using S&B 110gr factory loads . My 18” Grendel gets about 2525FPS with 123gr factory loads. I also have a 20” Grendel. My 20” Grendel gets about 2600 with 123s. The two are very close. Much closer than the video makes it seem. Under 250 yards with equal barrel lengths I would say the SPC is going slightly faster and has slightly more energy. Past 250 yards the Grendel wins and by 500 yards the margin is wide and just keeps growing. For hunting inside 250 yards they are pretty much equal. Hunting past 250 you need more power than either will provide. If I was shooting targets at 500-600 yards I would choose the Grendel and for 1000 yards I would step up to a Creed.

Does either one have a wider range of bullet weights available? I like rounds that can perform in multiple rolls (varmint to medium game, etc.). That's one reason I like quarter bores. BTW Caleb, I found a receiver from a Brazilian M1922. It's an FN made Mauser in intermediate size. That's what I plan on using for my 257 Bob build. What do you think of that choice? Will it give me the 3 inch COL?

6.8 can load from 75-130 grn depending on twist rate. I own both and have used on hogs and deer. Since I havce both a 6.5 cree and a 270, I love having some reloading redundancy in a SHTF scenario. Plus the 6.8 bolt is the same as the 224 Valkyrie, so I have some interchangeability there for spare parts...

224 val and 6.8 share the same mag. Ive put 6.8 in regular 556 mags and mine cycled just fine out of a pmag. Im guessing the 6.5 has to be completely different and the mag capacity wouldn't be great. I only load my 6.8 in 5 and 10 rd capacity mags to keep from mixing them up and I built it primarily for deer hunting... if I need more than 5 rds for a deer I probably shouldn't own a firearm 😂

7.62x39 in CMMG MK47 Mutant fills the gap between the 5.56x45mm and the 7.62x51mm and does a damn on hogs. All deadly when used for what they are intended for at appropriate ranges. When shooting through stuff the bigger and heavier the better.

7.62x39 fan myself! 20" SKS, 10" Draco and waiting on a brace for my 10“ AR build to be completed. I have an extra AR lower and because of my fondness and ammo stash, I just can't decide on another cartridge, I may just build a rifle in 7.62x39! With the shortage in reloading components I've learned that it's easy to pull bullets from steel cased ammo to change charges and bullet weights and make subs, which ends the need for 300blk! And I have 5K Berdan primers and a hydraulic de-primer, so reloading steel is an option as well.

Was the 6.8 an SPC 1 or 2 or an AR Performance there is a difference . I am 72 and walking with a 24" barrel when I could be walking with a 16" and get the same performance out to 400 yards I will walk with the 16". The 120 SST s will kill anything on the ranch and it is very accurate out of my 6.8. Long range is with my Creedmors.

Seems to me that the deciding factor is future round availability. 6.8 will be mass produced if the military goes with it in their Next Gen weapons

@DriveCarToBar

The military isn't going with the 6.8 SPC. They're going with a larger caliber. Armor penetration and machine guns dictate more oomph than an intermediate rifle caliber, so it's likely going to be 6.8x51 (.277 SIG Fury) as accepted by SAAMI. 80k psi!!!

Also 6.5 breaks bolts like no one’s business, bad for full auto. I like Grendel. I want one for a caribou rifle. I just don’t see military utility to it as a service rifle.

6.5 Grendel is clearly the superior round. Flatter shooting, more energy...no brainer

So can use on AR15 platform... need new barrel and bcg? And can use on 5.56 Magazine.
