300 AAC Blackout

[Irishtexan]

Greeting new member here.

I was looking for info on the 300 whisper on the net and came across the 300 AAC Blackout, viewing the drawing i noticed it is very similar to the 300 whisper, did someone change the size to bypass the copyright patent laws or is this simply a 300 whisper?
Im looking for a 300 whisper barrel and would like to hear from other users of the 300 whisper, especially people who have suppressed them, where you purchased your barrel and suppressor.

Here is a link to the 300 AAC drawing for comparison.

Thanks for any and all info, very nice forum, glad to be aboard, Allen.

Welcome alan, the 300blk is the "siammi spec"/ standard of the 300 wisper. Mine is a rem 700 with a aac barrel.
I have big plans but havnt got to shoot it as of yet.

 

[Cigarcop]

Yes they are all the same, many names for the same thing........personally I don't think you'll find a ton of info here but go to Snipershide and you'll be reading until your eyes get tired.

Right on Ollie, I forgot about that one!

Ollie mentioned AAC but I thought I would post the link for them. I built a customer a suppressed .308 using one of their barrels and one of their suppressors. My customer and I were extremely pleased with their products. I was able to shoot this gun after the load development was complete and it shoots between 4"-6" groups at 300 yards. I thought that was pretty good considering it's a 220gr bullet traveling about 1,000 FPS.

Alan,
I had one (300-221Fireball aka 300 Whisper aka 300BLK) built for me 3 years back by a very good local 'smith on a Rem XR-100 action, Lilja heavy barrel in a 1:8 and Jewel trigger over a laminate stock.
I shoot only subsonic handloaded ammo through a suppressor and am supremely satisfied.
Have taken deer out to 120 yards and paper punching out to 200--with a 240 Sierra I can hold 2 to 2 1/2 inches at 200.(No wind - a stiff breeze moves things a good bit even at 200 yards)
At 100 yards 1" is pretty standard. Again on a quiet day.
There are numerous projectiles you can use effectively if you reload, and I assume such since you are on this site.
With the suppressor, this round is VERY quiet and about all you hear is the firing pin hit, a small whoomp when the round impacts (that's at 100 yds-at 200 I can't hear anything but then again my ears are shot anyway)
I have recently began using Lehigh machined brass bullets for hunting and have found them to be extremely effective on deer as they open up nicely at subsonic velocities-deer drops and the others just stand there-good for thinning the population around here as they are way over populated and present a problem.
Anyway, if you go this route you should be happy.

Gary

It was not changed to avoid copyright but rather was 300-221 / 300 Fireball with final specs selected and approved by SAAMI. About 75 companies picked it up in the last 14 months:

20 shot group from a 300 BLK AR at 100 yards with iron sights. Not shot by me. Shot prone, not from a rest.

Aimpoint Micro with no magnification at 100 yards. 5 shots, 9 inch barrel:

Again i thank you very much for all the info you have shared.
Was wondering if anyone is shooting pigs with theres suppressed and how good of a job it is doing with the heavy slow mooving bullets.

my friend shot his new 300 blackout yesterday shooting 110 vmax hornady ammo and had 4 out ot 10 to blow primers another one had a very flat primer and the rest looked ok. lot no is 3131110. he is contacting the gun's manufacturer. what could be the problem. the only time i blow primers is when i overload. is there a problem with this ammo? thanks for any help as he has a LOT of this ammo.

 

[broncman]

Any time you blow a primer, you better check the firing pin. Could be damaged or gas cut causing more issues. Was it factory loaded ammo?

I have a Noveske barrled 300 Blackout that is very accurate with 110 vmax and the 125 SMK. Quite a few half inch hundred yard groups. Never shot subsonic though.
For me, the novelty wore off quick. Especially when 30 cal bullets got scarce.

It was not changed to avoid copyright but rather was 300-221 / 300 Fireball with final specs selected and approved by SAAMI. About 75 companies picked it up in the last 14 months:

The 300 Whisper was developed by J.D. Jones of SSK Industries. The design and name were copyrighted by SSK.

Everything that had "300 Whisper" on it, had to pay $$$ royalties to SSK. You bought a set of 300 Whisper dies made by RCBS, SSK got a piece of it - and that made 300 Whisper dies, reamers, and everything else - very expensive.

So the 221-300 was developed to side skirt the copyright issues - you could buy reamers and dies in 221-300 to make a 300 Whisper.

The legal issues were cloudy, but in time, the 300 Whisper died, and the 221-300 dominated the market.

AAC (owned by Remington) wanted a subsonic 30 cal, and since the 300 Whisper was tightly controlled (meaning royalties), and the 221-300 dimensions were all over the place because it was never standardized, AAC decided to come up with the 300 Blackout - the dimensions were changed ever so slightly, to avoid a court fight, and to allow the 300 BLK to work in Whisper and 221-300 chambers.

The dimensions of the three are so close, that Redding decided to make only one die size for the whole bunch - and just put different numbers on the dies depending on what you order.

".. with final specs selected and approved by SAAMI".

SAAMI does NOT select select specifications. Companies pick their dimensions, and submit them to SAAMI -SAAMI may approve the dimensions, or deny them with cause.

Then the manufacturer can make necessary changes, or go ahead without SAAMI approval. The 17 Fireball went on the market and SAAMI approval did not come until almost two years AFTER the cartridge was on the dealer's shelves.

The Nosler 280 Improved was first rejected with cause (there was a size conflict with another wildcat from the Remington Custom Shop)... Nosler redesigned the case, and it was approved.

THAT... is how SAAMI works.

The 300 blackout and 300 whisper are similar but are NOT the same. The blackout is based upon the 5.56 mm cartridge cut off at the neck and sized to 30 cal, while the 300 whisper is based on the .221 fireball case.

The whisper can be safely fired in the blackout but not the reverse, according to all the articles I have read.

It seems better to get a rifle chambered for the 300 blackout b.c you can fire both cartridges in it safely but the vice versa for the 300 whisper.

Technically the 300 blackout is a 7.62 x 35mm with ballistics similar to the 7.62 x 39.

Supersonic loads (i.e. 110 grain v-max have muzzle velocity of 2350 fps. The subsonic loads with 208-220 grain bullets can be used with a suppressor for a load with minimal report and minimal recoil.

I have CMMG AR in 300 blackout and it is easy shooting. Bought AAC 762 suppressor; awaiting Federal paperwork approval.

 

[kingsporthal]

That was my 300 blackout that blew the primers.

Was factory Hornady ammo with 110 gr v-max ammo, lot #3131110.

New rifle from CMMG. Broken down, cleaned and lubed the morning of first firing. Firing pin looked fine with pre-shooting takedown. I have not broken it down since shooting, but we did take bolt group out at range, and firing pin looked fine.

Thanks for suggestions.

You are suing different names for the same thing - the parent case for the 300 BLK is either the 221, or the 223, because the parent case for the 221 is any of the 222 family.

http://en.wikipedia.org/wiki/300_AAC_Blackout_(7.62%C3%9735mm)

The 300-221, the 300 Whisper, and the 300 BLK are so close, that there is more difference between any two 30-06 rifles taken off the shelf in a gun store, than between these cartridges.
