Check 300aacblackout.com It says it is built for the AR platform to allow a 30 cal bullet without reducing magazine capacity.

[Spanky]

It's a gutless 30 caliber round.

my understanding is that it is designed
specifically to use with a silencer using
heavy for caliber bullets to get accuracy
with a subsonic round in an ar


a common 30/30 will do just as good or
better and cheaper but louder.


an unnecessary expense unless you want
to shoot with a can (more expense)

Actually yes it does tell you what the .300ACC is. It is the .300 Whisper with a new name to get around SSK's rights to that name.

If you get interested in wildcats and take a look to see what is out there now it doesn`t take long to see that the same round may be know by more than 1 name. People seem to keep reinventing the wheel and calling it something different.   There is something to be said about the way they did it in the black powder days. They just used the caliber and the amount of powder the case would hold and sometimes the bullet weight. Had a friend that showed me an old Colt revolving rifle that was marked 44-40-265. That was a 44 cal. with 40 gr. of powder with a 265 gr. bullet. You could tell exactly what it was if you had never heard of it before.

The 300 Black out is a 223 case with the neck cut down to accept a 30 cal bullet, nothing more nothing less.

just a new thing to get your money.  they never quit. just like our government.

I have one and  enjoy shooting it. Basically you can shoot .30 cal rounds in a AR by just changing the barrel.
The brass is the same as .556 just necked up for 30 cal and cut down, So the same bolt, mags etc work.

I did pick up a barrel for $225 for my Encore also last month to play with some low power rounds.

I thought it was a 221 case necked up to 30 cal.

The difference is that the government can take your money and will send you to jail if you don't send it to them; while the manufacturers can only troll with shiny lures to catch spenders.

The .300 BLK can be made by shortened .223 or necking up .221. Six of one and a half dozen of another. It is a high efficiency round that is now typical of the popular short fat rounds. CVA is going to run the right bait by me in mid March with a 16.25" .300 BLK Scout rifle that should hit Academy Sports about that time frame. Yep, gonna hit that like a big mouth bass on a yellow wiggler. 

The only problem will be whether there will be ammo and reloading components available to shoot it.

It should be noted that the whisper was handled as it was to keep people from messing with it as it did not have a spec. from the ammo testers . The Black out was a tested and spec. round so those wishing to produce it really could not change it. I read that in an article that intervied the inventors of both. It was very interesting and both guys were doing as they did to protect the rounds more than anything , riches was not the goal it seemed. But like all articles , what is truth and what is not ?

I love mine.  I have it in AR format, Contender carbine and pistol.  I have been reloading it for 13 years.  I have killed over 30 VA whitetails with it with zero crips and runoffs.  Got my suppressor stamp in July.  Bought the Noveske AR the next day.  Shot 5 deer this fall with subsonic reloads.  All bang drops or ran less than 30 yds before crashing.  In Paraguay where I farm I have shot countless javelina and Brockett deer.  I love the round.  Its about all I hunt with anymore.

anemic... thats what it is! bah ha ha ha!

Id hate to get hit by one if anemic. The case strength will allow 125 grain loads to have excellent killing power, especially in a closed breach.

[SHOOTALL]

magnumitusis , Some just can't get over it.  At the end of it's effective range even the 300 WM is down to 300 BO veliosity 

[martineta]

It's similar in velocity and energy to the good old 30-30 win that can be used in an AR15 using the same magazine and bolt that a 5.56 uses.  How many deer have been killed with the 30-30 in the last century if they thought the round was anemic?  If I am looking for hard hitting at 1000 meters, I have my two barretts in 338 lapua and 50 BMG.  I shoot the .223's and 300 blackout a lot more.  Both are cheap to reload and do the job well for what they were designed for.

Given a choice between a 223 or a 300 Blackout I'd go for the 30 cal.
 
Fortunately there are other choices that are available = I went with a 6.8SPC that out performs both of these rounds.

I also have the 6.8 spc. out preform ? lets see 223 ammo cost less , 223 ammo is more aval. 300 BO uses less powder and there are hevier bullets aval. for it. So if you wish to shoot sub sonic the 300 BO will out preform the 6.8. If you like to shoot alot the 223 wins. One needs to decide what they want their rifle to do then choose a round that will do the most things they want. One could say a 3006 out preforms a 22 LR but it would depend on what needed doing . Both the whisper and BO were made to do a spefic task which they do well. besides you can shoot the whisper in the BO i believe.
 Jeeps first had 4 bangers and went about anywhere. Then came V-8's and they would spin their wheels alot power is not always the best application.

You certainly can shoot the Whisper in the Blackout since they're the same round.

Similar but not exact according to some . The chamber can be a bit different but I don't have the info aval.

Id go a little farther than say they're similar. Neck diameter on the Blackout is about 003 smaller then the Whisper. The other dimensions are roughly 010 apart. I believe that's a couple human hairs.

I have a buddy with one interesting round.
