6.5 Grendel or 6.5 Creedmoor upper?

LarryO1970 · 03-31-2008, 07:22 AM

I am in a bit of a dilemma... should I get an upper receiver chambered for the 6.5 Grendel, or 6.5 Creedmoor?

While I like the stability of the 6.5 Grendel... is it maxed out?

The 6.5 Creedmoor seems to have more to offer...

Which has the brighter future and why? Thoughts?

I would think the grendel has a brighter future. It's apparently more "commercialized" from what I've read.

My understanding is that the Grendel is already maxed out while the Creedmoor has more to offer...

I would wait and just go with a 6.8mm myself. I have 2 friends doing the same and I might just follow suit. The one big thing that's prevented me from seriously considering an AR-15/M-4 style is that the 5.56 is too small for my taste and the 6.5 costs too much to buy the rifle and then the ammo costs too much as well. I figure that the 6.8mm will cost the same as 5.56mm after its out a few months.

i dont think the 6.8 will be as cheap as the 5.56 until a military adopts it. thats why the 5.56 is so cheap, at least to my knowledge

It's not about cost... it is more about the performance and the availability to do more with the cartridge.

I am looking for long range accuracy and stability with the choice to do more with the case, charge and the projectile itself.

It is my understanding that the Grendel is maxed out while the Creedmoor offers room to play with variables. The only choice with the Grendel is with a 109 gr. projectile to get better performance while the Creedmoor has a whole lot more to work with.

That's comparing two different things entirely.

While the 6.8 does have accuracy potential, not nearly what the 6.5's do (in my opinion...), especially at long ranges (in excess of 400 yds).

I haven't done much research on the creedmoor, but I did quite a bit on the grendel when I was choosing my caliber. I ended up going with the 243wssm. The 6mm bullet choice is excellent if you reload. The 6.5 is also, but I liked the wssm line a lot. I've been very happy with mine. Check out gun page 2 for an idea of the wssm uppers. This guy (Mike) really knows his stuff.

Here's mine

Larry,

There really isnt a huge difference in these 2. They are both going to perform about the same with a slight edge to the creedmoor. If I was choosing between the 2 I would probably lean toward the creedmoor as it is probably going to wind up with the most major mfg offerings.

I have looked at the ballistics on both the 6.5g and the 6.8spc. I sure didn't see that, out to 600yds they are very close, past that the 6.5g BC takes over. The 6.8 SPC was designed to give greater firepower for CQB (Close Quarters Battle) than the standard 5.56mm round, but it's long range benefits are undeniable.
I think the 6.8 is going to see much more development from the bullet manufacturers than the Grendel. Then again, I liked Beta over VHS.

They really arent all that close. they start to separate at about 300 yds and after 600 the difference becomes alot. Its even more pronounced if you put the 6.5 creedmoore in.

Now there isnt anything wrong with using a 6.8 and at closer ranges it will kill a deer just as dead as any 6.5. When you start talking about long ranges though there is a huge difference. The 6.5 retains enough velocity to extend the kill range well past what a 6.8 can muster and thats kind of what Larry is talking about here.

it was my thought that the 6.5 creedmore is a ar10 "308 length" round

It is ... one would need the .308 AR lower.

LarryO1970 · 04-10-2008, 04:08 PM

I believe I've made my decision... going with the Creedmoor... many more options available with an AR-10 lower...

Much more $$$$$ too

BattleRifleG3 · 04-16-2008, 05:43 PM

Seems the Creedmoor is more of a competitor to the 260 Rem than the 6.5 Grendel. From what I've seen the Creedmoor has a shorter case to allow for the longer, most accurate bullets.

I think you kicked it ... the Grendel is a shorter case to fit in 5.56mm mags whereas the Creedmoor is the longer case requiring a mag well to fit 7.62 (.308) rounds.

Deersniper · 04-17-2008, 09:50 AM

6.5 Grendel would be my choice. The upper will fit any milspec rifle.

Yamabushi · 04-18-2008, 02:28 PM

6.5 Creedmoor in a FN SCAR-H or other modern 7.62 AR design is my dream. But a 6.5 Grendel in a FN SCAR-L, Magpul Masada, G36, 416, or other modern 5.56 AR would be great too. I'm not fond of AR10 or AR15 so I guess I will have to wait.

6.8 SPC is very disappointing at long range so is a no-go. I would prefer 7.62. 5.56 should die.
