I have a perfectly good complete lower needing a mate so I am looking for a complete upper in one of three calibers 6.5 or 6.8 SPC or the 300 AAC Blackout to go with it.  I am liking the 300 Blackout because all it will require is a different barrel to work in the AR Platform unlike the 6.5 or 6.8.  The 6.5 has better performance on paper but ammo is hard to come by as I do not reload.  The 300 and 6.8 ammo is readily available.  The 300 has the advantage of a 30 caliber round which is nice.  I will use this rifle mostly for hunting medium size game such as deer and hog....

I had thought of the 2 Soviet calibers the 7.62 x 39 and the 5.45 x 39, I understand both of these cartridges have feed problems in the AR Platform and finding  uppers for these two is really hard and pricey.  So what to do, I already have 5 AR Rifles, 4 in 5.56 and one in 22 LR.

Which should I choose and should I go with a 14.5 inch barrel, 16 inch, or 20 inch as this will be a hunting rifle I am thinking the longer barrel.  I am sure some of the ARF folks here have used or have these calibers and I am looking for feedback good or bad.  

Also can anyone point me in the right direction for complete uppers in the three calibers I am thinking of so I can go to the page and research some more myself...

Thanks

Since it will be a non-SBR'd hunting rifle I see no reson to go .300 over 6.8. If you dont plan to suppress it theres even more reason to go with a 6.8. I have a 16" 6.8 upper from ARPerformance and I think its hard to beat as a hunting rifle in my area (South Texas).

Agree with the above, the 6.8 is a fantastic hunting cartridge.  



I also have a 16 inch .300 BO that the wife hunts with.  According to her the 6.8 has more recoil than she cares for, I haven't ever noticed it to be more than 5.56 but some people are more sensitive than others.

Yes..above. Have both .300. &. 6.8,
Unless your goal is quiet Suppressed close shooting then go 6.8. 6.8 uses a different bolt and you will need 6.8spc mags. If just hunting, 3-4 mags will get you through for a long time. .300 requires no changes other than correct barrel.
For now 6.8 is much more available than either 6.5 or .300..... At least in factory loads.
Link Posted: 7/31/2014 5:30:11 AM EDT
I'll vote for the 6.5 Grendel.  Ammo is becoming more availabel, Wolfe makes it now.  I have a 20 inch Shilin barrel on mine.  Excellent accuracy (sub-MOA), light recoil, excellent ballistics, and long range.  What's not to like?

I would say 6.8. Plenty of GOOD factory loaded hunting ammo. 16" is perfect.. Plenty of velocity and still light and compact. Head over to the the 68 forums... Lots of info there.

I love my 6.8 for hunting. It's a great medium game rifle out to 300 yds. Light, accurate, and it feels and shoots very similar to my 5.56 AR's I train with.
Link Posted: 7/31/2014 5:36:47 AM EDT
I've taken mule deer and hogs with 6.8. Great caliber. YHM 16 inch barrel has treated me well
Link Posted: 7/31/2014 5:39:12 AM EDT
6.8 was a fad.  I vote 300 blk as you can get ammo for it, 223/5.56 brass can be reloaded to 300, and just because you are not using it for the intended purpose now does not mean you will not later or that it will not accomplish your goal.  

I think you need a poll and I vote 300
Link Posted: 7/31/2014 5:44:19 AM EDT
I would add look at where you will be hunting and match the choice to that.  For the blackout you really don't want to be taking shots beyond 150 to 200 yds.  If you are in FL I know there aren't too many great plains type areas, so the BO would work well in most situations for you.  Like others have said though where it shines is in short barreled usages.  I keep a 300BO pistol in my truck as what i consider the perfect truck gun.  I have a 10.5" barrel on it and the OAL is just over 2ft.  It's very light, handles very well, and the recoil on teh BO is shockingly soft, maybe even lighter than the 5.56.  My afg up front probably helps that a lot, but in any case with just a rubber crutch foot serving as the "stock" there is no discomfort at all.  As you also mentioned it's far easier to deal with from a logistics standpoint as it only requires a different barrel; you can drop any of your 5.56 BCGs in and go.  The bullet designs specifically for the blackout now are also highly effective on small to medium game.  The 30/30 has taken more deer in North America than most other calibers combined.  As the BO is ballistically similar to the 30/30 results should be similar as well.

Now, conversely, the 6.8 has a much greater range, but requires special parts to work.  You can use any other carrier you already have, but you'd have to change the bolt to do so (not a big deal but it's still a deal).  Have to get specific magazines as well.  I've considered building my next upper in it because I already have lots of .270 projos around for my .270 WSM, and as I typically shoot lighter bullets in it they would do double duty in a 6.8 for me.  It's just become one of those "when I get around to it" things.

In either case I don't think you can go wrong.  Like I tell everyone considering buying or building an AR, the AR is a tool.  Make the tool match the job.

This.  
Get a caliber that doesn't meet your needs now because your needs might change unexpectedly.
Or, get the 6.8 and get fantastic hunting performance but regret not having a caliber with a cool name like "black out".

I have two .300s, one 16" and one SBR.  working on a 6.8 now as a new hunting rifle.  Why not do one now and go ahead and plan to build the next one?
Link Posted: 7/31/2014 9:19:54 AM EDT
6.8 a fad?? I don't think so. Everyone around here stocks ammo for it. Local shops, Walmart, bass pro, gander, cabelas. I see a lot more good hunting loads for 6.8 than I do 300 BO.

Saying that the 6.8 is a fad is an ignorant statement. None of them sell like 5.56's... So ae they all fads? No. The 6.8 and 300 are both here to stay, but will never be as mainstream as a 5.56 or the 308.
Link Posted: 7/31/2014 10:41:16 AM EDT
Depending on your definition of medium range, all three cartridges offer similar performance.  Hunting ammo for the three is comparably priced.  I'm a Blackout fan because I like the efficiency of the cartridge, but realistically any of these cartridges will work for you.  Pick whichever one tickles your fancy.

Looks like the 6.8 is moving out ahead, and after doing some more research on the round I can begin to see why...

Best Price I have found on a complete upper is here at Bison Armory $495.00 complete

http://bisonarmory.com/18-spr/

Is this a good price and a good company to deal with
Link Posted: 7/31/2014 1:05:14 PM EDT
Never dealt with Bison Armory but the specs on the barrel are fine.  Really only an AR Performance or Noveske barrel might be better.

I think the 6.8 will be perfect for the OP's needs.

Since you were thinking of the Russian cartridges, why not have the best of both worlds?

Wolf is now producing factory 6.5 Grendel STEEL-CASE ammo. See here.

So you can now have a modern, multi-role cartridge that is designed for your AR and is cheap to run.

ETA: BTW, I'd go with a 16" bbl. 14.5 you need a stamp, unless you pin a flash hider, and 20" is probly more than you need.

Good guy and good company but that upper is not complete. Read the fine print. Add a carrier, muzzle device and whatever else is missing. $640 is the least you can get that complete.

The Grendel is the one size fits all of the AR world IMO.  Great performance for all barrel lengths and long reach with the right barrel.  For deer hunting, varmint hunting, and long range paper punching I do not believe it has a equal.  If your want a variant that does it all very well go Grendel.

I would go 6.8. Take a look at some of the groups on 68FORUMS or Predator Masters on the rifles built with Black Hole barrels by Ritch's Precision Guns. Match grade polygonal rifled barrels turned to your specifications in a short time without getting a second mortgage on the house.

I have: several 6.8, several 300aac, 5.56, .308, and rebuilding a few 7.62x39 ARs. Each has its merit.

90% of the time when I actually go hunting, I just grab a 6.8. I's great for the type of mid range hog & deer that I do.

Having said that, 300bo has its charms. It;s great for shooting suppressed, and you get really good performance from it out of a very short barrel.

Since you don't reload, you can also add 7,62x39 to the list. Not as good suppressed, as 300bo. Not as flat shooting as 6.8. But it's cheap as hell to shoot, and I'm seeing some fairly effective other the counter rounds at good prices (eh. Hornady SST costs $35 for 50 steel-cased rounds).


6.8 would be my first choice, unless you really want to do both SBR and can. Then, IMOHO, it's a toss up between 300 & 6.8.
Link Posted: 8/11/2014 11:41:21 AM EDT
For Hog hunting in the flats of FL I would say a 6.8 would be enough cartridge. The 6.5's miniscule long range advantage over factory loaded 6.8 is not going to matter in 99.9999% of shots taken. When I load a mag for Hog hunting it says "6.8" on it.

$13.50 for 6.8 S&B ammo.

GLshooter is right,  head on over to the 68forums & begin your journey towward enlightenmentf what the real potential & popularity of the cartridge is.

6.8 a Fad?... only by non-hunting wanna-be mall ninjas that buy something without a given purpose & then post about what they don't understand.

Link Posted: 8/11/2014 12:23:29 PM EDT
I never saw much use for a 6.8.  IIRC 6.5 had better power and ballistics.  300 makes a better sbr and suppressed gun.  That said - 308 beats the 6.5 in everything but weight.



I got both - 300 and 308.  FWIW the 6.8 is a 270.  I also have a 270 bolt gun.  It is not my first choice on hogs (it was, but not anymore).  Light 270 bullets gave me penetration issues (one shot failed to penetrate the shoulder, one bounced off the skull).  Abet the 6.8 is a lot slower than the 270 so maybe the light 6.8 bullets will hold together better and not fragment like my 270's did.

Define "Medium Range" hunting.

Grendel has more energy and less wind drift than the 6.8 SPC, even when you compare a 14.5" Grendel to an 18" SPC II.

There are at least 35 factory loads for the Grendel, including ones from Hornady, AA, Precision Firearms, PPU, and now cheap steel case.

Within 125yds, the animal won't know the difference if you shoot them with a 120gr 6.8 SST, or a 123gr 6.5mm SST, but within 125yds is definitely not medium range hunting.

If you want a better chance of connecting across a farm field, the 6.5mm is easier to hit with in the wind, and retains energy much better than the 6.8 SPC II. The Grendel is like having 6.5x54 Mannlicher-Schönauer in an AR15.  Guys and gals have used it to hunt medium-heavy and large game successfully, at distances up to 400yds with boring repeatability.

You don't need a long barrel for the Grendel either, as has been parroted over and over again.  It does really well from short pipes, which surprised me because all I heard before getting one was that you need 24" to realize any potential from it.  That was coming from people who only look at muzzle velocity, but hadn't wrapped their heads around BC yet.

The performance difference between my 22" .260 Rem AR10 and my 16" Grendel with the same bullet is 200yds, both of which are supersonic out to over 1300yds anyway (Grendel 1318yds, .260 Rem over 1500yds with the 123gr A-MAX.)

Funny, Gunbot.net lists ONE Grendel round in stock at $1.25/round and about two pages worth of 6.8 rounds in stock, starting at $0.64/round.  Just sayin' - those 35 different bullets don't matter if it ain't in stock.

Just because Gunbot doesn't have hits doesn't mean out of stock.

Precision Firearms

New Loads for 2014:

100gr Barnes TTSX

6.5 Grendel 130 Berger 130 VLD-Hunting  (.552 G1 BC)

Those are just the new loads from PF, with the usual loads they have still available ready for sale, ranging from 100gr Nosler BT's to 130gr Nosler AB's, 107gr SMK's, 108gr Scenars, 123gr SMK's, 123gr Scenars, etc.

Alexander Arms has many different loads they sell, ranging from PPU 120gr MPT for ~$15 a box, to premium bullets from Barnes and Swift for hunting, as well as the target loads.

Alexander Arms 6.5 Grendel Ammunition

Hornady can't make enough 123gr A-MAX and 123gr SST's.  I order them for under $18 a box before the shooting season begins, by the case.

SWFA 6.5 Grendel 123gr A-MAX

Wolf steel case is going to make a big deal for the marketplace in terms of accessibility and affordability.
