Home Forums Hunting & Shooting Ask The Gunwriters 300 AAC BLACKOUT.....6.8SPC all over again?

The traveling salesman for AAC makes his bi-annual drive by BS.

Time and time again you make outrageous claims that never pan out then disappear for a few months, only to appear again when a .300 AAC thread appears and you throw out more outrageous claims and claim the check's in the mail... rinse, repeat.

Too funny and TRUE!

aww c'mon, tell us what you guys really think.

I've always thought the round was interesting, even long before I thought about owning an AR. The commercialization of the round, making it readily supported by guns, ammo, and components, is appreciated.

Never underestimate the bureaucracy of the Army Procurement System... it rushes forward at the speed of a glacier...

I think it's a great round. One that I have been seriously considering for some time, whether it be in the flavor of Blackout, Fireball or Whisper.

But it is a niche round and I think a salesman for AAC would be better served promoting honest virtues of the round, instead of going from shooting site to shooting site constantly trying to denigrate the competition, with wild claims.

I am also considering the 300 BO instead of a used-new lever 30-30. RSilvers is one of the creators of the round I believe so he is really more than a salesman. The 6.8 is a fine round but I just don't want to have a separate collection of magazines that look similar to my other magazines. The other question that I have had was will a round fire if you drop the hammer on a blackout round accidentally chambered in a 5.56 gun. For sure the hammer will drop, don't know if the pin will reach the primer.

I would hesitate to call someone a 'creator' of a round that was already in existence. That would be like calling whomever came up with the 6.8 Spec II chamber the creator of the round. Silvers may have massaged the specs slightly and been a driving force to push it thru SAAMI but that's about it. Let's give credit where it's due to JD Jones for creating the round.

In addition, it is my contention that if you come to a website to push a product, you should be open and upfront about who you are and what your relationship is to the product/company whenever you post. That way, everyone knows your agenda and there can be no doubt that your position is tainted by your employment status. No one can then mistake your information as independent, personal experience when you post.

Sadly, I do not know if the .300 BO will chamber and fire in a 5.56 chamber. I know the 5.56 can be loaded in the 6.8 chamber and in certain cases I have seen, the extractor will hold the round tight enough that it can be fired. Usually only happens once though......

Within the parameters of the AR design, the .300 BO/Whisper is a fine round.

you should hone your reading skills as I said "one of the creators of the round"...further the BO was not in existence, I presume you are talking about the whisper, very similar but not identical.

He said "a creator" which has the same exact meaning as "one of the creators", so his reading skills appear fine.

It's pretty obvious they Whisper/Fireball was copied and tweaked just barely enough. It would be highly disingenuous to pretend AAC had never seen the .300 Fireball/Whisper before and created this from blank canvas.

Its a matter of interpretation, the round was not in existence, the whisper was in existence. Your arguing as you usually do just to be arguing. I don't deny that Rsilvers was influenced by the whisper, but that has nothing to do with the round being in existence. It was not "in existence" its a new creation, but very similar to the whisper.

Says the guy that was arguing the meaning of "a".

What claim was outrageous and did not pan out?

The credit JD is due is for building interest in the 300-221 concept of shooting subsonic. JD did not create the 300-221 - he trademarked his version of it as the Whisper(R). People have been shortening 5.56mm cases and opening them to 30 cal since at least 1969. Also, most of the dimensions were exactly copied from a Remington design - the 221 Fireball.

The interest is due mostly to SAAMI standardization and making several types of ammo available.

300 BLK was picking final dimensions for a standardized 300-221 Fireball and submitting them to SAAMI.

Are there SAAMI specs for the .300 Whisper and clones?

How is your round different?

DF

No, there are no SAAMI specs for those. 300 BLK is the only SAAMI standard.

I am not sure how it is different, as I don't know what those other rounds use for dimensions - as they are not a standard, so each drawing I have run across is different. I can say what we did...

We took a 221 Fireball and opened it to 30 cal. We set the headspace datum to not be on a radius. We picked the radii to something reasonable. We picked a neck diameter which would be compatible with brass formed from 223 or 5.56mm without neck turning. We picked a throat diameter 0.0005 smaller than 308. We picked a throat length that would allow a 220 Sierra to be loaded to AR mag length and have 0.010 jump.

Plenty of misstatements and examples of questionable claims in this thread, the last time we hashed this out.
