 6.5grendel vs 6.8spc vs 300BLK best Whitetail AR platform ????

Looking to build a long range whitetail AR platform i have a few routes i can take

6.5grendel seems to have better long range ability and i have always been a huge fan of the .264 bullet. Grew up shooting a .264 win mag and killed alot of deer with it.

6.8spc does decent down range and has the .277 bullet, also a fantastic whitetail bullet.

.300Blackout dont think it shoots as flat as the others but may be a better option for shots taken within 200 yards and the .30 cal bullet is proven


SO long story short what do you guys think... i will admit i am leaning towards the 6.5 the ballastics tables make it look solid.

Your thoughts??????

A few years ago I was in the same conundrum as you.
I opted for the 6.5 Grendel. I now have 3 Grendel ARs,
and I have not one regret.

I am not a ballistic genius and honestly have limited knowledge of all three calibers but from what I understand of tbe three:

300 Blackout is about maxed out at 200 yards with the bullet drop being significant at that range. Biggest advantage it has is the ability to shoot subs which are probably best for 100 yds and in shots.

6.8 is good out to 500 yds, for hunting and making reliable ethical kills on deer, probably less than that, say 300 yds depending on operator.

6.5 is similar (performance wise) to 6.8 out to about 500 yds then begins to out perform 6.8 significantly due to better BC bullets.

I guess biggest thing for you to decide is what's long range for shooting deer to you, can you reliably and ethically make kills at that range, which platform delivers best at that range? 100 yds and under and you want to shoot suppressed, 300 Blackout. Under 400 yds, 6.8 has more choices/less expensive ammo. Over 500 also want to shoot long distance for various reasons, 6.5.

None of the calibers as of yet have ammo available at walmart, so you're either handloading, finding at LGS, or ordering online.

All good points . it dawned on my after writing all this ..."what the hell would be wrong with just getting an AR-10"

Cost of the rifle would be about the same as the others

Ammo is easy to get

And the .308 win is proven to be more effective than all them

CON is of course weight ,a hunting model AR-10 can be heavy but i have been packing heavy rifles around the woods my entire life.

SO i think i have narrowed the field down to either the 6.5G or the AR-10 .308win .....again your thoughts???

Go with the 6.5 - it will satisfy your initial preference listed in your first post.
Will be lighter and more affordable to yourself or for resale later.
Go with a 20 inch barrel...

The nice thing about 6.8 is you can use the lower you already have (assuming you own a AR 15). I bought a CMMG 6.8 upper for this years deer season, and while I took no deer with it I have been very happy with the upper.

I have been in the same boat as you. I even looked at 25-223., but I didn't get a response back and it is probably harder to come up with components than either the 6.5 or the 6.8. I already have an AR10 and it is very accurate given my aging eyes. But also very heavy scoped out I bet it is close to 12 pounds. To damn heavy to carry very far. I will go with 6.8 seems like there is more of everything uppers, brass, bullets, just more support. I am never going to shoot a deer over 300 yards, there is no need to. Good luck with your choice.

Personal preference I suppose. 300 Blackout doesn't really do it for me. 6.8 would be good as well but with the cheap Wolf steel cased 6.5 Grendel ammo coming out that would make practicing with it a fair bit cheaper, even if I reload. I would like to buy a 6.5 upper, just need the money first.

6.5 Grendel. You can do the same or better as a 308 in a lighter smaller package. 6.8 is ok but not as versatile. 300 Blk belongs in supressed SBRs doesnt really make sense in anything else.

I think it is the better cartridge, but that is a matter of opinion. The best reason I can come up with is the fact that Wolf Ammo will soon have steel cased plinking ammo on the market priced very close to their steel cased .223. If MagPul would bring out some 6.5G PMags, I would be a very happy camper!

6.5 is a great round. I shoot a 6.8, and actually out to 500 yards they are so close it's scary. Just to add though, Bill Wilson has made an agreement with Tula, and they will be producing 6.8 steel cased ammo in 2012.

I don't know if you actually realize how heavy a .308 AR 10 type rifle is. My 16" LR308, loaded with a 20 round mag, and a scope, and a sling, and a bipod,was almost 15 lbs. That's not really bad for some, but I have a shoulder injury that made it difficult for me to shoulder it quickly and fire it, and keep it stabilized for follow ups. That's why I switched over.

That is great news! Hopefully it will be at a price point that is competitive with steel cased .223.

That would be a dream come true to me as well. I'll actually shoot my 6.5 more (as in a lot more) when that ammo comes out and is readily available....

Now if I can just get someone to make steel cased .458 SOCOM....

It is a matter of type of terrain hunted/target range & choice 3-400m or y +/-. (e.g Here in Appalachia 300+ yards is hard to come by except some fields/pastures & power/gas lines. So, I don't really need a 6.5G.)


The Tula deal with the 6.8 is going to be great!
PS I think it was Barrett that made the deal with them?

Thanks! Here in Missouri 300+ yards is almost impossible to find for hunting distance. 100-150 yards is more like it, with under 100 being most common. The more I keep reading about the 300 AAC Blackout, the more I like it. For my purposes, it would fill several niches at the same time, shoot suppressed, hunt with, use as an HD weapon....

My own finances (we have a 3rd kid on the way) and the fact that the ammo isnt quite readily available yet is all that's stopping me.

The 6.5 Grendel does not do the same or better as the .308 at anything other than punching holes in paper with the given barrel lengths and subsequent velocities (you're talking about 16" barrels in this thread). The one distinction is that it can be had in the AR15 platform, which will save approximately 1.5 pounds in weight in similarly equipped rifles.

Since 16" barrels seems to be the common running thread in this thread/equation, I then submit that the 6.8 SPC is the superior hunting cartridge out of the ones listed here, with the 6.5 G being superior past 400 yards in punching paper ONLY.

Honestly, the difference in performance between the two even out to 600 yards is so negligible that 99% of the shooters out there will not notice the difference. And the .308 trumps both of these cartridges out to 600 yards in performance on game....

These are FACTS that can not be disputed.

Does anyone have some chronographed MV's for the .308 Win and 6.5 Grendel out of 16" barrels?

Do you have a link where you are getting 2500fps from a 140gr VLD in a 16" barrel ?

The reason I'm asking is that David Fortiers personal load for the 123s is just about 2500fps from a 16" barrel, and most data I've seen for the 140 VLD is 2300fps from an 18" and 20" inch barrel.

Hornady lists the 123gr at 2350fps for the 16" barrel, and 2620fps for the 24" barrel.

Also, regarding the 165gr in the .308, the M118LR, a 168gr SMK from my 16" barrel was 2450fps. My hand load was just south of that.

The .308 in a 16" platform leaves a lot to be desired when you factor in the recoil, the weight, the initial expense of the rifle and accessories. Add to that that there is almost nothing that it shares with the 5.56 platform other than some LPKs, so you have a lot of expensive and proprietary parts when replacement is needed.

The 6.8 and the 6.5G are much better options for most people.

That's why I was asking if someone had actually chronographed either of those from a 16" barrel. Ammo makers have been known to inflate their numbers, and I guessed the numbers I posted would be fairly close. The real point is there is very little difference in impact energy between the two, but the 6.5 bucks wind better, the ammo is significantly lighter, and can be chambered in lighter weapons.

I get just under 2500 fps with the 140gr VLD in my 24" barrel. I have never pushed that load to it's absolute limits, and I imagine I could squeeze out another 20-30 fps with it....maybe

Using Hornady's numbers, the 140VLD loses 270 fps going to the 16" barrel. That would put the 16" at 2230fps or there about.

If your going to shoot the 140VLD out of a 16" barrel to hunt with. You'll need to know the minimum expansion velocity.

Honestly, you need to tailor your loads with a 16" barrel. The max effective range on most big game is going to be near 400 yards with any existing bullet (and that length barrel)....

Maybe not,... If your 2230fps (See 4 posts above) & the minimum expansion is 2000fps. I don't think you'll make it to 400yrds.

Thanks! Here in Missouri 300+ yards is almost impossible to find for hunting distance. 100-150 yards is more like it, with under 100 being most common. The more I keep reading about the 300 AAC Blackout, the more I like it. For my purposes, it would fill several niches at the same time, shoot suppressed, hunt with, use as an HD weapon....

My own finances (we have a 3rd kid on the way) and the fact that the ammo isnt quite readily available yet is all that's stopping me.



Sorry for the delay!
For your situation, I'd wait until the dust settles on the 300BO. You got diapers to buy.
Right now, it's for those who have to have the latest crave or a tacticool suppressor shooters.
I chose the 6.8 for yotes & deer. Possibly, hogs & groundhogs. I like the flat trajectory. Just in case I hunt a field or powerline. The Tula deal is icing on the cake.

Honestly, you need to tailor your loads with a 16" barrel. The max effective range on most big game is going to be near 400 yards with any existing bullet (and that length barrel)....

Maybe not,... If your 2230fps (See 4 posts above) & the minimum expansion is 2000fps. I don't think you'll make it to 400yrds.


I'm saying the 140VLD is not an ideal game round out of the 16" barrel. Go for one of the lighter bullets....

Sounds like we're saying the same thing!
Have a good one!

6.8spc does decent down range and has the .277 bullet, also a fantastic whitetail bullet.

.300Blackout dont think it shoots as flat as the others but may be a better option for shots taken within 200 yards and the .30 cal bullet is proven


SO long story short what do you guys think... i will admit i am leaning towards the 6.5 the ballastics tables make it look solid.

Your thoughts??????
A *REAL* AR-15 "noob" here.

Man, I'm glad so many people have so many options available to them about expanding on an AR-15 platform - I really am!!!! You're all lucky ...

I gave up on "rifles" a long time ago (30-35 years ago - and I'm now 64) when I began to lose almost all sight (uncorrectable) in my right eye and just refused to shoot a "righty" bolt action all crossed-over. And as a contact-lens wearer, having a "righty" semi-auto spitting out brass and residue in front of my face when shooting it as a lefty just killed my interest in looking at a "high powered" rifle.

Luckily - and I won't mention the manufacturer, y'all know who it is - came out with a "lefty" AR-15 a while back ... and I fell in love!!! Weak .223 or not, it was better than shooting nothin'!!!! (I even bought their .22LR conversion kit so I could practice with the same "feel" - including trigger pull - of a real AR-15. It works perfectly ... )

Of course, with some states placing restrictions on this lame little .223 round as far as "hunting" - it simply doesn't kill much more than a coyote cleanly - I was left punching a LOT of holes in paper. (Hence, the .22LR conversion kit ... )

The same company now makes a 6.8 SPC full upper half - and we all know the superior knock-down realities of a 6.8 SPC over a .223 or even a 5.65 NATO - so as much as I'd love to have the slamming power of a 6.5 Grendel, unless the guys in New Britain, CT make one - not sure if a full upper is an option on their standard AR-15 lower - it looks like I'll be limited to taking down what I can with the 6.8 SPC within 200 meters or so. Can't even get them to commit that they're even *thinking* about a 6.5 Grendel in a left-handed version. Pretty sure they've "thought" about it ... but either can't make one or just figger they can't sell enough to justify the cost of manufacturing 'em.

I've seen some pretty impressive numbers from some Hornady boat-tails in 6.8 SPC so I'm pretty anxious to get my new full upper half to pin on my beautiful lower before fall. I'll take some wild boar and a small white-tail or two - and be satisfied!

Happy hunting, everyone!

Stag does sell a left handed upper receiver without a barrel on it...

http://www.stagarms.com/product_info.php?cPath=17&products_id=249

You could get the upper, and buy an after market barrel chambered in 6.5 Grendel and make your own left handed Grendel....

Just a thought.

Or, you could do the same with your own left handed 300 black out...

6.8 for me.

No major reason, that's just what I wanted. I can't wait for cheaper ammo!

Good discussion. I have a few AR15's all in 5.56/223 caliber. There is LOT you can do with an AR in 223, but for hunting deer I feel the 6.8 SPC (or 6.5 Grendel) is a much better choice. As mentioned previously 300 Blackout is a very specialized round although with proper handloads could be good on deer inside 200 yards. Personally my hunting needs are met with other rifles.

I shoot Service Rifle cometition with an AR15 built for the game. This is really good practice and great fun! All in 223 of course.

the AR10 has its place but because of the larger size and higher weight handles like a totally different weapon. I had one in 308, cutomized by GAP, tricked out with all the best stuff, but it never had the "light and quick to action" feel of the AR15, so I sold it at a significant loss. don't miss it one bit.

On the other hand a 6.8 SPC or 6.5 Grendel might be nice to have.... If the mention of reasonably price ammo does happen I suspect it will really sell,

If you mean Com Bloc & Black box Federal/Am Eagle pricing, yes. .223 is cheaper. But, cheaper price 6.8 ammo will be next year (Cheaper than $14.87). Otherwise, it runs about the same. Actually I saw Winchester .223 PDX1 Defender that was over $32.00 a box. More expensive than any 6.8.

But, then it is just an upper & mag change away. You can do both.

you cant go wrong with the 6.8 or 6.5.
If you SBR and can it, the 300blk is great, but only if you SBR/can it.
308 AR is an awesome beast, but is a serious PITA to move around and set up.

My light carbine/pig rig is a 6.8 with a 3-9 scope. Very accurate, lots of power, and will be effective out to 300 (which is really where my shooting ability ends)

Just an FYI.

Silver State Armory is now loading a 6.8 140 Berger Hunting VLD that is super sonic to 1000 yards and still has 500 ft/lbs of energy at 800.

UPDATE:
Oh, its 1800fps. Also, SSA uses a propitiatory blended powder. That's why they can get 2401fps out of a 16".

Me too I guess...I missed the post about this ammo. Awesome...I thought I was doing good with reloading using 120 gr. SST's...If/When I draw an elk tag, I'll have to get a few boxes of these. My 120's will be fine for deer...and prolly elk too if I do my part.

Don't forget another AKA = 300 Remington Fireball.
Yeah, I know. I shoot a TC Contender. I thought about getting a 6x45 SSK at one time. But, never tripped the trigger on ordering one. The Whisper® Series was/is listed & shown. It was a wildcat niche suppressor caliber.
I was talking about after the hype dies down. Like - The 6x223, 6.5x223 & 30 HRT (Not the orig. Herrett) are starting to get a little talk now.
