Re: 300 AAC BLACKOUT
You might use the search function, there's a big thread about this already. Other than standardizing the cartridge getting it to meet SAMMI specs I don't see the advantage over the .300 Whisper. Plus, you can form brass from .223 cases. Not sure if that will work with the new .300AAC...
I'm very curious about this cartridge too. I just placed a order with McGowen for a 16" .300 Whisper bbl last week. From my understanding you can push a 240gr SMK at around 1025fps and it only slows to around 925fps out at 300yds(really retains speed in other words).
I hear guys are getting sub-moa groups out to 300yds. IF my setup does this I will be happy.

Nope, McGowen makes them. They told me it might take a little longer because they have to borrow the reamer. Fine with me, they charged me pistol barrel prices since it was only 16". Worked out to be around $250 for a threaded, chambered, SS, Savage barrel.

DAMN! Even better. Can't wait until my stamp gets here and my bbl gets done.
Anyone have a link on how to form .300 whisper brass? On that note, can .300AAC brass be formed from .223 like the whisper?

This is a subsonic cartridge designed to be used in conjunction with a suppressor. Is that the case with the 6.8?

Re: 300 AAC BLACKOUT
The 300 Whisper(R) can do everything the 300 AAC BLACKOUT can do, but is proprietary and so could not have been submitted to SAAMI. Without being a SAAMI standard, you are guaranteed to not have any major companies make guns and ammo for it. Second - there is a lot of load data floating out there for the 300 Whisper which is set up for bullets, powder, and OALs which are not reliable in an AR15 - 300 AAC BLACKOUT is a fresh start in that regard, Finally, 300 AAC BLACKOUT will have affordable factory ammo.
I don't see 300 AAC BLACKOUT as just a subsonic / suppressed round so much as a 30 cal solution for the AR15 which works with standard magazines and bolts. So you could hunt with it and a 16 to 20 inch barrel and it would still be great for home defense and LE - like the 6.8 - but with lower cost ammo and less muzzle blast.

Re: 300 AAC BLACKOUT
my 762SD will work just fine on one, correct? the 762SD-N doesn't seem to be that different.

I was wondering this too. However, the AAC Blackout uppers w/ 9" barrels would seem to invalidate your warranty on a standard 762SD suppressor as they recommend nothing under 10.5" IIRC.
Maybe Robert will chime in.

Re: 300 AAC BLACKOUT
anyone know how much accuracy or effective range you would give up shooting the 9" versus the 16"?

Could you expand on that a little? I'm in the process of building a whisper bolt gun at the moment and have heard about people having issues with ARs. I really like the looks of that 9" AR upper and I already have a SBR, so you got me thinking about this new caliber. What exactly has AAC done to improve the reliability/function in the AR platform?
Are there reamers available yet? McGowen has my order for a .300 whisper barrel now, I might see if I could get it in .300 AAC.

Re: 300 AAC BLACKOUT
Theres nothing new here...other than the attempt to take credit for what JD Jones did with the Whisper. Good marketing and PR work will work wonders...

Yes, PTG has reamers for 300 AAC BLACKOUT. In fact, they archived and stopped selling all of the older wildcat reamers.

Re: 300 AAC BLACKOUT
Was told the 762SD-N has an extra baffle, and it suppresses the 300 blk round better. Also heard the 762SD suppresses the 7.62X51 better than the 300 AAC BLK

None...
The most efficient barrel length for this cartridge is 9"
The 16" is there to satisfy the non NFA market.

Re: 300 AAC BLACKOUT
I don't see the 16 inch as only making sense if you cannot have an SBR.
16 inch has significantly better range and power and possibly better accuracy with some loads. For supersonic ammo, which I see as most of the market, the longer barrel makes a difference.
We are even working on 20 inch hunting barrels.

</div></div>I keep forgetting that it also is being used for supersonic loadings.
My opinion has always been that the 300/221 Fireball, 300 Whisper(R), and now the 300 BLK
were primarily designed as suppressed solutions that also have supersonic capabilities.
It surprises me to read that you see the supersonic loadings being "Most of the market".
(Especially since AAC released their SBR 300 BLK products first.)
I just think AAC and automatically think quiet I guess...
Then again, I could just be short sighted since my 300 BLK project is a suppressed SBR.
Obviously you have the potential for the 300 BLK to be a solution with AK like ballistics,
it just never appealed to me as such.
Some would argue that an AK would be a better solution in all aspects to that problem,
other than accuracy and familiarity with the platform.
(Cost, availability, durability, field proven, etc.)

Re: 300 AAC BLACKOUT
i can't freaking decide if i want the 9" or the 16". i'm gonna be doing a little of everything with it, hunting, plinking, range fun, etc. it will have a 762SD on it.
i guess the 16" makes the most sense for all of that? but that 9" sure does look sweet....

Re: 300 AAC BLACKOUT
This is a 30 caliber solution for the AR which works with a standard bolt and normal full capacity magazines. The fact that it happens to be good for subsonic is just a bonus - but one that most people will not use.
We are making much more supersonic ammo than subsonic. 7.62x39 just does not work in ARs. With 300 AAC BLACKOUT, people can hunt with their AR - in places where 223 is not legal for hunting.
Here are the installation instructions for the Rem 700 barrels that are in stock now. Think excellent youth hunting rifle for the lightweight barrel.

Re: 300 AAC BLACKOUT
Alright I want to order a 9" upper tomorrow for my SBR. Who has them for the best price?
Is anyone making dies for them yet or just using .300 Whisper?
From what I've been reading the 220gr SMK bullet is whats being listed as the subsonic load. Why not the 240gr SMK? Is it too long for mag?
What all do I need to be able to form the brass out of .223 cases?
If anyone had more information in general that would be AWESOME.

Right now Forster is the only company producing dies.
Factory ammo will be nearly impossible to come by until 2011.
As far as making brass goes:

I plan on putting once fired 5.56 brass on stripper clips and then cut them just below the shoulder on a ban saw.
Then anneal, full length size, and then finally trim.
All the 9" uppers were sold out last I heard, but I also heard that some people backed out: http://www.silencertalk.com/forum/viewtopic.php?t=62927
The price for the uppers seems to be constant @ $1,080

I resized Remington 300 AAC BLACKOUT cases with each of the following dies, and then put a metric pin gauge in each, to see the largest pin that would fit. The goal being to see which dies resized the cases to the optimal inside diameter for ideal bullet pull without over-working the brass.
Forster had the benefit of having both the factory drawings and factory fired and unfired 300 AAC BLACKOUT brass - and so they knew the neck-wall thickness.

Thank you very much for the information above Dr. Phil and rsilvers. I searched high and low to find those Forster dies/product number on the net but no luck. I left them a message and will get them coming ASAP. I'd love to have some rounds R2G when this thing arrives.
I bought one of Allen Arms last 9" uppers today and should have it next week.
