Not without signing a non disclosure:

"I received an email from a principal at AAC just the other day "announcing" this "new" cartridge. In his initial email he went out of his way to tout the platitudes of this "new" round, and really make it look like something new and better than what we had ever seen before. The main crux of his email was this:

He knows that Olympic manufactures 300 Fireball barrels and that we have had great success over the years with them. This "new" cartridge of which this gentlemen represented himself to be the "project lead" in its development, was so close to what we make that he said, "Your chamber is probably already within the spec", but that he recommended we go to HIS reamers, and "recommend you change the name on your barrels to 300 AAC BLACKOUT. People will be asking you for it soon enough." I informed him that they already do ask for it, and that Oly calls it the 300 Fireball, and that we have been manufacturing it for almost 30 years.

After several email exchanges, he wanted me to sign a Non-Disclosure Agreement just to see a print of the cartridge. I was a bit thrown off by this, not wanting to get involved with or support an organization, project or individual that wants to push a new branding as an exclusive or otherwise fantastically new development, when it is little more than a rebranding that others have used and made famous over the last 30 years. Remember: JD Jones and all his wondrous rampages about anyone who made a 330/221 Fireball after he branded the name "300 Whisper"? Anyway, the whole NDA thing caused me to make some calls. After 17 years at one company and nearly 25 in the industry, I am not without contacts and resources of my own. In about 30 minutes I confirmed that the cartridge, although submitted IS NOT SAAMI approved as of yet. this was given to me as the reason for the NDA request. Hmmm... But I also received confirmation from a couple of inside industry sources that the chambering is almost identical to what Oly and others have been using for the 300 Fireball/Whisper® all along.

Specifically, I was told, "the headspace is exactly the same as 221 Fireball, the chamber is exactly the same as the 221 Fireball except the neck is .337 tapering to .335. The max case length is 1.368", chamber is 1.378 to where the case mouth would be. Throat is .309 for about .18 then it's a 1.5 degree into the bore."

Anyway the good news is they are advertising a partnership with Remington. Near as I can tell the partnership really seems more like a seller/client relationship with AAC being the buyer of ammo from Remington. In one of his letters he states that there are 5 Million rounds on order. Looking forward to testing some.

While I anticipate fully that the marketing will continue with the re-branding of the 300 Fireball as the 300 AAC Blackout as the next greatest cartridge to hit the AR, we all know it is not. Something that a theology professor taught me about scripture and doctrine sort of applies here: If it is new, it is not a revelation. If it is a revelation, it is not new". Same principal pretty much applies to the AR after 50 years of tinkering. Yes, there will be some exceptions, most notably the WSSM conversions, but for the most part that adage holds true.

The best news of this, is if it all goes through as projected, is that the ammo will be commercially loaded and available in case lots, that will totally reinvigorate the cartridge, and in the end, in spite of any negatives in the process, I'm all for it.

It will always be a 300 Fireball to me."
