SPC seems to have more ammo available.

6.8 SPC but since this is Arfcom get both.

As a owner of a 6.5 grendel I am biased. I think the get both applies here though. However.......


If you are going for a long range AR15 with excellent accuracy then the Grendel is a good option.6.8 SPC is a good alternative and cheaper but is not as accurate and does not shoot as far. Both are good in the short to mid range but in long range the Grendel is better. Of course a .308 caliber AR would also make a good choise but the beauty of the 6.5 and the 6.8 is they both fit onto normal AR15 lowers. .308 needs a special lower. (Yes I know there is one company that make a lower with interchangable magwells) If your looking for a good rifle on a ar15 platform that would be good for TEOTWAWKI then I would say stay with the 5.56 because ammo is much more available. Hell, get all 3.

The grendel seems to get slightly higher velocities and muzzle energy than the SPC.

I was going to buy a 6.8 upper for my Bushmaster AR, but after a little reading and researching I have decided to choose the 6.5 Grendel instead.  

After my research, I've decided that there is nothing the 6.8 does that the 6.5 can't do' plus the 6.5 has better long range numbers.

While I think that the 6.8 is still a formidable cartridge, for my type of shooting I think the 6.5 will work better.

What would the intended purpose of said rifle be?

Link Posted: 5/26/2008 6:34:07 PM EDT
6.5 Grendel seems to do a reasonably good job of matching the knockdown power of 6.8 at short-to-medium distances, while absolutely beating the pants off 6.8 at relatively long distances. It is the better all-around cartridge, IMO.

I chose the Grendel, but I own one, and I'm admittedly very biased.  

I don't know much about the 6.8, so I can't speak for it.  But I do know that if you're a reloader, the bullet selections of the 6.5 are awesome.  That little Lapau 100gr Scenar has a B.C. of .444 and muzzle velocities should be around 2700fps.  Put that in a ballistics calculator and watch what it will do.  You're shooting a bullet that's almost twice the weight of standard 55gr .223 ammo and it is still cooking at 600 yards well above supersonic at 1624 fps.  All this from a standard AR-15 platform.

6.5 grendel cartridge is better (slight advantage only).

6.8spc = wayyyyyyyy more stuff available from a variety of manufacturers.


6.5g screwed themselves in that regard.

Plus there are bullets available for it from 90gr-144gr, AFAIK.
SMK's, FMJ's, SGK's, etc.
There are a lot of other 6.5mm cartridges out there, this one can use a lot of already-existing bullet designs.
Yes, the 6.8 is a .270, but good luck stuffing the same bullet as a .270Win in there.

Both have their niches, but if I absolutely had to make a bright-line choice, 6.5 Grendel. Especially if I'm set up to reload it.

That said, Get All 3! (6.5, 6.8, 5.56)

We don't have a whole lot of 6.5 Grendel manufacturers, but the ones we have a very good (and I'm not suggesting that those companies making SPC are sub-par.  Far from it, I know Barrett, Cardinal Armory, RRA, et al, make good stuff.  The Grendel has Sabre Defense, Les Baer, JP enterprises, Alexander Arms, Lothar Walther, and Saturn.  The biggest gripe I have with the Grendel is that it's difficult to get brass right now.

A good urban combat round. I don't live in the country where long shots would be more common.

Go Grendel, once you've gone Grendel, you'll never have a need for the SPC, while the opposite isn't true.



Link Posted: 5/26/2008 7:53:27 PM EDT
Grendel hands down.  Ballistics, bullet selection, etc.  It'll do whatever the others can and then some.

Two different rounds, but I dont see where you get two different niches....Yes, the Grendel can shoot at longer range's, but that doesnt mean it cant be used for a CQB role.

If your looking for something to hunt with then they both will do the job...if your looking to shoot at long range's then the Grendel is your huckleberry  I really dont see/know of a reason why I would recommend the SPC over the Grendel.

If I was looking for a short barreled carbine and something for hunting deer, 6.8 all the way.  If I wanted a mid-long range SPR, 6.5.  I think the 6.8 is better for CQB and for 100 yard deer hunting range.  But that is just me.  If you lived in an area more open then your circumstances change.

6.8 does have better terminal ballistics for people. For deer, the 0.3mm difference in diameter for a soft point isn't going to make a difference.

Funny thing about the Grendel, though - It doesn't lose much speed between 10.5" and 16" of barrel. Bill reports a max speed of 2600fps for the 100 grain Scenar in the 16, and 2500 in the 10.5. I should have gotten the 10.5 but hindsight is always clearest.

CQB and terminal effects are completely dependant on bullet choice guys. Use the right bullet and that .3mm will have no discernible effect.

Link Posted: 5/27/2008 6:47:51 AM EDT
I think my original sentence was sufficient. 6.5 doesn't have the type of fragmenting bullets the 6.8 has.
Link Posted: 5/27/2008 7:08:10 AM EDT
I already have a 6.5x55  and a 6.5x57, so I am a bit biased.  But the fact is there are more bullets available to the reloader in .264" than .277".  I would choose the 6.5 Grendel over the 6.8 SPC.

Link Posted: 5/28/2008 5:51:39 AM EDT
Grendel! For punching paper out to 1000 yards, and 6.8 for hunting under 400 yards. And the 400 yards is purely my choice because most of us should not try anything over 200.

Each cartridge has its merits and each has its “bands of brothers”.  And neither side understands that they need the other.  If the 6.8 did not have the 6.5 to fight with in the early days, there would have been nothing to say. The reverse is also true.  Bill A. needed Paul L.W. as a foil to keep up the interest. Its marketing..pure and simple.

The Grendel was a PPC mod and the PPC is pure competition!  The 6.8 was developed for another reason!  Again, both have unique uses and in some areas overlap.

The total number of people at the development level, for both cartridges, was four!  Bill & Arne, Cris & Steve.

Anybody want to try it today?  I did not think so!

Ok, so we need each other.  Back to the bloodletting!

How, exactly?

*****************************­****************************************
<­BR>6.5 beats 6.8 all the way around.  

The main reason 6.8 has received the high volume of favorable official military attention it has is because of people like Barrett who are all "mobbed up" with their Pentagon political connections.  It's not nearly as easy for Alexander to play the graft and corruption games with the crooks in the Pentagon that the supporters of the 6.8 can, since they're the spoiled, petted darlings who've been supplying the military's .50 BMG sniper rifles for years.

Besides, I hate the .270 caliber anyway, Jack O'Connor's moldy corpse be damned.  All the brouhaha surrounding the .270 Winchester over the years is 90% hype, just like all the brouhaha about the 6.8 SPC.
