Need some help deciding what to build next with my PSA lower.
If anyone can help we with so e feedback on either calibers it would be great.

Check the FAQ's in the varaints section. There are threads for each caliber, and a comparison thread.

Of all the variants, I chose the 6.5 Grendel.

Three years on, I now own 3 Grendel rifles, and I have zero regrets.

6.5 does everything 6.8 does out to 300yd, then it pulls ahead and blows everything else out of the water ( excluding a few wildcats) . The 6.5mm bullets retain energy (velocity) MUCH better than about any other bullets until you get into the .338 caliber and above range.

The 6.8 is supposed to perform better out of short (sbr) barrels, but a 16-18" grendel will get you to 800yd+ no problem. Obviously more barrel=more velocity.

The 6.5 grendel kept me in the ar15 world when i was ready to ditch the platform for the base-762 ARs (ar10, dpms lr etc.).

Right now you can get a variety of match grade ammo for the 6.5, and wolf gold 120 gr Mpt for $13/20rnds, and barnaul steel cased is in the pipeline and is supposed to be out later this year.

What do you plan on using the rifle for exactly?

If you want to do long range shooting/hunting, I would lean towards the 6.5

Both due to velocity possible are limited to apx 300yds for hunting. The 6.8 has a better choice of hunting bullets, the 6.5 has better choices in target bullets.

close to 300yds? c'mon, you need a 20inch barrel with the grendel to get anything while the 6.8 can do it with a 12inch barrel. Under 400yds, the 6.8 outshines the 6.5. After that, who cares, you are gonna grab a .308!

Grendel. Worst case, you run out of brass or if it stops being produced, you can make your own out of x39 brass. and Wolf is making cheap plinking rounds for it.

The 6.5 will do anything the .308 will do at long ranges, in a smaller AR15 size package.

Not really, A Grendel doesn't come close to the velocity or terminal performance with the same weight bullets. If you want to talk about hitting paper then the 6.5 is close but if you use the best 6.5 bullets against the best 308 bullets the 308 wins again.

The difference is about negligible. What can you kill with a 6.8 that you cant with a 6.5 with a similar length barrel? The 6.5 even with as short as a 10.5" barrel stayes supersonic well beyond 600yd. Like i said, 16" will get you to 800+ no problem with a grendel. I shoot my 18 incher to 1000yd often.

Also, the comment about 300yd max hunting range isnt entirely correct. Mark Larue killed an elk at 405yd with a grendel, and ive seen several deer killed between 500-600yd.

Eta: I see a lot of misconception that for whatever reason you NEED a long (20-26") barrel for the grendel. Its just not true. The grendel is most efficient (bbl length vs velocity) at around 18". 16", the legal minimum without sbr paperwork and tax is enough to hunt every north american animal except maybe moose and caribou to at least 300yd... now consider that same rifle can weigh 5-7lbs and be able to accurately engage steel/paper beyond 800-900yd. You really cant lose with the grendel.

To get the most performance and long range out of a G, you won't be using a 16"-18" bbl. More like a 24"+. Does it preform well with a 16"? Yup, sure does. Is the 16" the choice other LR G shooters choose? No...

I see the dead Elk from God Larue mentioned a lot. H shot one at around 380yds with a 6.8. What is your point? Both will kill at those distances but a .223 will also if you want to get technical.

Inside 400-500yds, both are an excellent choice. After that the G will pull away a little due to the better bullet. I have 2 6.8s and plan to add a G/264LBC soon.

I can easily and cleanly kill deer at 400+ yards with a 223 and 75 grn bullets. The 6.8 or the 6.5 will do the same well beyond 400.

346ci,

That goes without saying. Longer barrel = more MV, less wind drift etc... im just saying its not absolutely necessary to have a long barreled grendel, even to shoot long range.

The 405yd elk and 500-600yd deer were brought up because someone else said the 6.5 and 6.8 were "300yd hunting calibers" (paraphrased). My point is that it wasnt an entirely true statement and they can be used considerably further.

My main point is that all variables as close as they can be between the two calibers, the 6.8 has a negligible lead for 300yd (slightly more energy, but realistically it makes no difference to the target) at which point they level out, and beyond that the grendel pulls ahead. So in 6.5 vs 6.8 discussions, i say why cut yourself short? The 6.5 does better all around in my opinion, even from short barrels.

no it's not slight. you take the 6.5 and 6.8 out of 14inch barrels and you tell me to 300yds it's equal.

I agree with most of that other than the 6.8 is the better preformer out of short bbls, at any distance. I like the 6.8 better but to each his own. If I had a longer range, I'd already have a 6.5. For now with 300yds being my longest shot, the 6.8 works fine. If that doesn't scratch my itch, one of the .308s come out to play.

I'm fortunate enough to have some of both plus 300 blackout & 7.62x39 rifles. Also have a farm with my own 800yd range, & where I occasionally guide hunts. My 7.62x39 rifles get used 99% of the time because I can use cheap Commie ammo to plink with, and use Barnes bullets to hunt with. In these small cartridges Ive used lots of stuff & have given up on anything but Barnes - mostly because occasional hunters have problems with shot placement under pressure.

I like the ballistics of the Grendel the best, but hunting ammo is lacking. I have a beautiful rifle w/ 18" lothar walther barrel Tom & Mike from Spikes gave me for hosting some shoots for them, & because they knew I love the cartridge. I shot some running deer in MN with it & was disappointed in the penetration because of my poor shot placement.

Good 6.5g Ammo is expensive, but hopefully the Wolf stuff will cure that problem. I have all the stuff to handload ammo but never make time to do it. With a good Barnes bullet & Russian plinking ammo, this would easily eclipse my use of the 7.62x39. Everyone cites better close range 6.8SPC performance, but it's sort of a moot point at that range. If a 1500 ft lb 6.8 will kill a hog at 100yds, so will a 6.5g with 1450 ft lbs. The men separate from the boys at the longer ranges.

I have a 6.8 Jay, the owner of YHM gave me as a thank you for taking him & his mgmt team hunting. It is very accurate & kills great with the Barnes bullets I can buy off the shelf from SSA. Plinking with it is a very expensive proposition, though. I leave this gun at our farm in MN where I hunt deer once a year. No sense in dragging it back & forth on the plane since I'm not going to plink anyway. I have another 6.8 here. I have another Spikes 6.8 here, but i rarely shoot it.

I have 7.62s in every config imaginable because friends at Adams Arms knew I was a fan & had me help them get a bunch running with their piston systems. I always loved the fact a 7.5" had more energy than a 16" 5.56. You can buy the cheap Russian 124g HP stuff that still fragments, all for $200/k. You can buy them loaded with Barnes from DoubleTap, I think. The latest mags CProducts put out have been great for me.

If Wolf Comes thru w/ steel cased stuff, I'll probably shelve the 7.62x39 stuff because the Grendel does SBR stuff just as well, and long-range better. The Grendel gets a bad rep for it's supposed lack of SBR performance because its long range legs overshadow the fact it's within a few % of 7.62 or 6.8 numbers. At short range, you've got more than enough energy with all 3 anyhow. In the end, I like to shoot my stuff & ammo cost trumps all when performance is pretty close.

You really cant lose with the grendel.


Yes you can kill something at any range but ethical kill? Look at the photos posted here on arfcom of Grendel kills with a 120gr TSX, it is maybe 30% open because that bullet was designed for 260 velocities and the G can't push them that fast, the further out in range the less velocity and the less expansion. The companies that make the bullets publish the expansion velocities so people can make the correct choice for hunting bullets. 300yds is about the maximum range for reliable expansion. The 6.8 has many more hunting bullets made for the velocity range that the 6.8 can push them to. The 100gr Barnes TTSX maybe the best hunting bullet made for the G. The 6.8 is a better choice for hunting, the 6.5 better for target because of the avail bullets made for each.

no it's not slight. you take the 6.5 and 6.8 out of 14inch barrels and you tell me to 300yds it's equal.



123 amax @ 2400fps. At 300 you have 1090 fpe.
110 accubond @ 2590fps. At 300 you have just shy of 1000 fpe...

Unless im missing something? Im not well versed in the various spc chambers etc...

Can you get factory 6.5G ammo that pushes the 123 AMAX to 2400fps out of a 14" barrel––-I know Hornady lists it at 2350 from a 16" barrel? Or are you comparing handloads to factory ammo?

Ive seen a couple reviews that said they were getting 2450-2490fps out of 16" barrels with the factory amaxs. I also remember a 10.5" barrel review that was getting 2250-2300 fps with 123gr smk reloads.

Lets low ball it, say its only 2250 fps from a 14". At 300yd you still have 950 fpe. So its 950 vs 995... IMO pretty negligible either way. And the amax is still going to catch up and surpass the 6.8 nosler.

At the muzzle, its 1638fpe vs 1383 fpe (assuming lowball 2250fps. @2400fps its 1573fpe). I make no arguement against the 6.8 having 100-200fpe more energy at the muzzle. However, by 300yd theyre more or less equal, and inbetween i dont think the 6.8 can kill something the 6.5 can't, ethically even.

It would be great if someone with some experience with short grendel barrels could chime in. All i have is my 18" and i dont follow the 6.5 forums as much as i used to.
lwrkeysfisher  [Member]

Don't disagree, just want to be sure we are working with facts. when referencing Hornady factory loads, I think the difference between the two rounds is very small out to 500yds.

The 6.8 does have a slight advantage for hunting because of the number of hunting bullets/loads available, and because the lighter hunting loads (e.g. 85gr TSX @ 3000fps from 16 bbl) provide excellent terminal ballistics and an MPBR of ~300yds. Also, while the 123AMAX is a great bullet, but I have reservations about its use on game. Hopefully Hornady will close this gap and release an equivalent 120gr SST bullet at some point.

The 6.5 has a pretty significant advantage beyond 500yds (beyond 400yds in gusty winds), though I think this may also become a toss-up when SSA releases their 140gr Berger load (reportedly later this year). The problem with any of these heavy for caliber options though is the BC's are likely evaluated at higher velocities (6.5 Creedmore or .270) and may not really apply to the slower velocities of the 6.5 and 6.8.

For the op, you picked the best two to choose from and don't think you can go wrong with either. I would probably go with a 18-20" Grendel AND a 12.5-16" 6.8.

Lots of good photos here if you're a hunter.

Ballistically, a 16" Grendel and 16" 6.8 SPC are virtually identical within 300yds using similar bullets from the same bullet maker, but the Grendel starts out 150fps slower, while matching the 6.8 at 100yds for energy, then slowly starting to out-gas it from there outwards.

The Grendel offers more versatility in application from a 16" barrel when it comes to a little more distance, but a lightweight carbine isn't exactly the best platform for shooting at distance either, although many shooters achieve impressive results out to 800yds and further under good conditions. In more erratic winds, the Grendel is about like a .308, limited to 600yds for high hit probability with a 1st round.

The Grendel has a wider spread in ammo availability in the price point department, starting with Prvi Partizan 120gr MPT's under the Wolf distribution middle man, up to high-end cartridges from Hornady, Alexander Arms, Precision Firearms, and will drop the lowest rung on the price point ladder with steel case this year.

The 6.8 has a larger selection of box ammo options, but starting at higher price points and going into the high end realm as with the Grendel match and expensive hunting projectiles.

If you are shooting within 275yds, I'm not sure you'll notice any difference in the two.

I wonder what kind of velocity the 140 gr Berger will reach out of a 16" tube. And will it fit in an AR mag?

No one knows. My guess is ~2300fps, more if loaded longer but then you have mag issues. I know some folks on the 6.8 forum have been successful with 130gr bullets, so the 140 seems like the next logical step if following the G philosophy. Not really my thing, but others will like it I'm sure.

My point is that it wasnt an entirely true statement and they can be used considerably further.My main point is that all variables as close as they can be between the two calibers, the 6.8 has a negligible lead for 300yd (slightly more energy, but realistically it makes no difference to the target) at which point they level out, and beyond that the grendel pulls ahead. So in 6.5 vs 6.8 discussions, i say why cut yourself short? The 6.5 does better all around in my opinion, even from short barrels.



You got to remember not everybody has your marskmanship skills... Most people cant shoot the side of a barn out to 400yds... lol... i see people go to the range all the time claiming their 6.8 is the best thing to hit the planet and then i look at their targets and it looks like buckshot hit it... and that is @ 100yds that is a concept i cant comprehand... but to each there own... thank the lord for good 6.5 rifles and good marksmanship...;

NOW i didnt claim, that the 6.8 is not an accurate round... its just my experiance to see that the poor misled spirits that lack marksmanship are for some reason drawn to the 6.8 round... and when i ask why they choose the 6.8 over the grendel they always reply... Well i didnt want a sniper rifle...! its almost like they cant be saved..!!!

I was researching which to build and went with the 6.5 Grendel. It will be a hunting rifle, it doesnt matter to me if there are more available bullets for different calibers, do a search on youtube on long range shooting, barely any 6.8's, but there is a couple pages of 6.5G.

I haven't seen any G snobbery here lately so please don't start. It is NOT the best thing since sliced bread....

A majority of the 6.8 shooters are not target guys, the choose the 6.8 due to its power and ability to use a 16" or shorter rifle. I've seen .308 groups like you mentioned, if a guy can't shoot, he just plain can't shoot. The gun plays a role in that but most of it is shooter. I haven't seen a G at my range yet but I know it is deemed a target round. I'm going to add one to the collection one day when I find some longer ranges. For now my 6.8 and .308 works best for target or hunting.

Here is a 100yd group with a well broken in Noveske, Mod 1 chamber and 1/10 twist(not ideal) in a rest. I have sold it since but even with the chamber and twist using factory loaded 110bthp, it still shoots damn good.


Here is load devolpement using my ARP with the X43 chamber and 1/11.25 twist. Laying over the truck's hood, no support. These are rounds 50 to 75 through the bbl so it's not even broken in yet. Looks like the Accubond @ 27.5gr is going to be a winner. I'd like to get some more velocity though.


Either one of those look like buckshot??? If so, let me know where I can get some of that for my shotgun, I can really impress my shooting buddies if I take a deer out at 100yds using buckshot.

Groups thread from 6.8 Forums, many more great groups on that site. If groups are what get you off.

If it is a target gun and you want to shoot over 300 yards perhaps 6.5G is the way to go. If you want to shoot deer or hogs, most shots will be less than 100 yards. For this, bullet choices and abilities of 6.8 with a shorter less cumbersome rifle make this a better option IMO. If you are buying a gun to hunt with and just plan on shooting 500 yard shots at animals I am wondering what the ethics of that would be with either round’s terminal effects given the abilities of most shooters. JMO

Since we are showing groups this is what I got last time out with SSA 110 grain pro hunter out of my outdated SAAMI chamber Ruger 6.8. Not too bad.

Nice...!!!

i'm glad to see a good rifle in the hands of a capable Shooter...

i meant no disrespect to 6.8 owners... i truelly believe that the 6.8 and 6.5 are practically equal between 100-300 yds even with the same length barrel... although some would claim that the 6.8 has the edge in the shorter barrels within 300 yds... thats not true..!!! but if they want to claim that... so be it... point is... the op will do fine with either or...
i believe that the 6.5 will always be slightly more accurate... and it will always "slightly" out porform the 6.8
the advantages of the 6.8 is the commercial acceptance of the cartridge... the commercial production of factory chamber rifle's in 6.8 and the abilitly of going to most sports stores and finding 6.8 ammo...
and that alone can make the 6.8 a better choice...
but i think thinkgs will ghange up for the 6.5 soon..

OK, fine -16" barrel - factory loads:
http://shopwilsoncombat.com/68-SPC/products/409/
How close to that is 6.5G (with factory load & 16" barrel)?
& those don't even use the Hornady 120 SST with a BC .400

__________
Oh. 346ci, try using AA2200 powder. Allow of folks have been getting great accuracy & velocity results with it.

the short barrel (16-18") 6.5 Grendels work amazingly well. And just because its super accurate, why wouldnt it work for hunting?

From another board:

My brother shot a Mulie with his Grendel/16" AA M4 carbine barrel and a 120 Ballistic tip at 493 yards, killed it clean(Double lung) through and through, we never recovered the bullet.


This is the last Grendel I built, I used a 18" stainless Alexander Arms match barrel. Had it turned down and lightened up, threaded 5/8-24 for a suppressor and shortened to 17". Scary accurate with Factory Hornady 123 A-max match loads.



This is my Grendels best 300 yards groups shot last fall with Hornady match 123gr .

Good luck, as in THIS or is more like THIS. And yes there are hundreds if not thousands more where these came from.


And as for the mule I would have been surprised if the bullet didn't pass completely through, as it has a high sectional density and would not expand/breakup/disrupt at that distance/velocity.
