New Caliber - 300 AAC Blackout

[constructor]

Silvers,
Who is making firearms for this round and who is making ammo and when will the ammo hit the shelves?
I can move about as fast as anyone when it comes to producing wildcat ARs.
I could have rifles in 4-5 weeks.

 

[HorseSoldier]

As Ssgt I had to take charge of the battalion as lead officer, and then another three months getting the actual CO used to operations. I professed to my soldiers to become proficient in semi-auto because full auto was completely wasteful. Especially as desolate as we were. We couldn't even get batteries for our NV.

Is that bonus level for Call of Duty 2?

 

[LeonCarr]

Yet another somebody re-inventing the wheel. J.D. Jones/SSK did this what, 15 years ago?

Just my .02,
LeonCarr

"... In my state, it's legal to own one, but you go to jail for using one. So, for me, this round has no use."

Huh? What does that mean? Elaborate please.

 

[taliv]

GA, in washington state, it is legal to own suppressors but not to shoot them. stupid. search for posts by member Ranb and click the links in his signature if you live in WA and are willing to call representatives.

(though from your name, I'm guessing you're in georgia)

 

[Mags]

This round looks better than the 6.8 from shorter barrels. If ammo is available for 15 bucks or less per 20 this round looks promising. I have been contemplating a 5.56 SBR for suppressed use and a 6.8 in an 18 inch upper for sometime but a 9 inch 300 blackout sounds like it will do both pretty well.

Just as I wrote it. I can legally buy a Tax Stamp to purchase/own a silencer, but if I USE it within the borders of WA State, it IS a jailable offense (no exclusion for law enforcement either). The only option is to transport it to neighboring Oregon or Idaho to use it.

Constructor,

If you want to make uppers, call Pacific Tool and Gauge and buy a reamer and gauge set.

We expect another 100,000 rounds of ammo in November but most if not all is reserved for the military and companies that want to develop rifles. Hopefully soon after that we will have mass quantities of ammo for commercial sales. This is still early adopter time and a good time for rifle makers to get stuff developed for the Shot Show.

The amount of ammo coming is adequate (almost certainly more than 6.8 ammo sales by all companies combined).

 

[unwise11]

this is stupid, i wish someone somewhere would explain all these people are doing is creating more dead calibers. maybe someone should try something groundbreaking. like .408 cheytac, or .338 lapua.
oh wait, someone already made those, ok stop making more new ones and make more 308 for me.

Silvers,
I think Dave at PTG called me not 15 minutes after it was released.
I'll kick it around but, want to see the ammo available first.
Be interesting to see what the big SWAT forces do with this.

 

[highlander 5]

J.D. Jones might have made the cartridge and chambering first,but have you priced his uppers? Yikes! Years ago I called about have a Ruger M77 MK II rebarreled to 300 Whiisper and was quoted a price of $1200 !!! I don't begrudge someone makeing a profit but that's a bit much for a simple rebarrel job. I would like to find out what the pric of an upper would be with a flat top and 20" barrel.

 

[db_tanker]

one question I haven't seen asked yet...


will this round chamber and fire safely in one already cut for a 300-221 Fireball or Whisper?

What about those who have a Contender single shot and just use your ammo to fireform into their chamber? Are the dimensions close enough to make it safe or did you size the brass to be non-compatible?

 

[Tirod]

The amount of ammo coming is adequate (almost certainly more than 6.8 ammo sales by all companies combined).

No doubt it's noticed I live in Missouri, so, I'll wait to see that. If it can be done, great. Economies of scale being what they are, I know there will be an uphill battle to produce it.

I'm not naive enough to expect $15 a box, and it's not reality in an age of creeping inflation and commodity demand on brass, etc.


Les Baer announced they were going to produce a large quantity of .264 LBC brass. I don't track that caliber, how's that coming along? As there is only so much production capacity to make ammo in the US, much less worldwide, it will be interesting to see what the source is.

 

[rsilvers]

We did not purposely make it incompatible with 300 Fireball, but we can't guarantee compatibility due to that being a wildcat.

I have a RUAG 300 Whisper (R) ammo drawing and their ammo is a fit for our chamber.

There is also the issue of gas port pressure and OAL. I posted loading data for ammo that is known reliable in feed and cycle. I highly recommend not using pre existing 300 Fireball load data for subsonic use as they mostly use OAL too long and powder too fast for military levels of reliability.

 

[Bartholomew Roberts]

My last tour I had a SDMR modified M16A4, slightly different ammunition but I was able to reach out much further than the M4.

Much further? Care to quantify that with some actual numbers and data?

I kind of doubt the inital offering of ammo will surpass that of available 6.8 choices.

Since it came up, and there is a knowledgable AAC/Rem rep present, with the large focus on production of AAC/Rem's new caliber, I would love to see Remington also look at their 6.8 Rem SPC offerings and press out some more too. They (you) can have a great influence on the success of both cartridges.

 

[rsilvers]

I meant in terms of quantity of rounds manufactured, not variety of rounds.

 

[HorseSoldier]

I'm interested to hear some more on this too from a BTDT sort of guy like Raindownmyblues . . .

 

[rsilvers]

The only way I could make that happen is to have AAC place an order for a new type of 6.8 ammo and then Rem would make it to our specs and we could distribute it. And that may happen but it would be more of a next year thing if we do it at all. But if we did do it, it would be full speed.

Thank you for answering my question and I apologize for the thread drift.

 

[S. Hill]

The main advantage (as I see it) is with the heaviest bullets, suppressed, at sub-sonic velocities, at distances over 100 yds. You have a very specialized round for a very specialized application. The heavy VLD bullets maintain their energy WAAAAAY beyond what you might think.

If you are looking for a deer cartridge with super-sonic velocities, the 6.5 or 6.8 will probably have better performance than the light bullets in the .300.

Mr. Silver, I am also wondering about using the new Rem. ammo in the .300-221 chamber. (not so worried about the other way around) Is there a case capacity difference between the two?

 

[Kernel]

The .30 Rem AR looks to have about 20% more case capacity. The .300 ACC will always be a weak sister.

 

[rsilvers]

The 30 AR is low magazine capacity.

I recently ran this data for another thread (on hunting with subsonic cartridges).

Here is the drop data for a 240gr SMK launched at 1100 fps (50 yard zero)

_Bullet_           _BC_ _MV_         0      50     100     150     200     250     300     350     400 | YARDS
240SMK            0.71* 1100 >   -0.00    0.00    4.55   10.98   18.01   25.38   33.00   40.83   48.84 | drop (moa)

240SMK            0.71* 1100 >   -2.70   -0.00   -4.76  -17.25  -37.73  -66.45 -103.67 -149.64 -204.60 | drop (inches)

240SMK            0.71* 1100 >    0.13   -0.02   -0.17   -0.33   -0.49   -0.66   -0.83   -1.01   -1.19 | drop per yard (inches)

240SMK            0.71* 1100 >    1100    1080    1061    1043    1027    1012     997     984     971 | velocity (fps)

Note that at 300 yards, it has as much drop, and drop rate, that a normal .308 does at 1000 yards. While it does "retain" velocity fairly well, ranging is critical. If you are off by 10 yards at 350 yards, you will miss by 10 inches.
