Thats why I dont like AAC :)

That has happened sometimes when the item did not pass final inspection or testing but the salesperson 'knew' all the parts where there. It was a result of being bigger than a few guys making stuff by hand but not big enough to have a good inventory control system. AAC has adopted Remington's inventory control system and all parts and bill-of-materials are tracked and only when something is really done does it go 'in stock.'

It works both ways as we have 300 AAC BLACKOUT Model-700 barrels in the building that people would love to get but because the thread protectors are not screwed on yet, they are not 'in stock' in the computer because they are not assembled. That means that the website won't even take an order for them and the sales people will tell people they are not in stock. They are scheduled to be assembled (by screwing on the thread protector) but it has not yet happened.

Sorry about that.

It's a new Shilen bbl, based upon what I have read here, to avoid potential pressure issues, the throat must be tweaked slightly. by doing so I can shoot the Remington factory loads without issues & still be able to hand load as well.

You dont think after the trigger debacle Remington is stupid enough to load ammo thats going to destroy firearms and disfigure users do you?
Remember Remington is run by lawyers and accountants now and they know whats good for you.

The ammo is designed to not exceed max pressure in 300 AAC BLACKOUT barrels. If you want to shoot full power 300 AAC BLACKOUT ammo in your wildcat chamber, you should ream it or else pressure may go above the 55,000 psi limit.

Probably some ammo companies will make ammo designed to shoot in either 300 Whisper(TM) or 300 AAC BLACKOUT chambers. Such a load is possible, but would be lower velocity - sort of like some of the 6.8 SPC ammo that is lower velocity.

Good point, being Remington brass it may not hold up and a case rupture "may" occur.

We gave a lot of special attention to the brass. It was annealed in the neck and left unpolished for visual verification. The shoulder was kept as large as possible for headspace. The brass was tested for cracking under various conditions. The primer pockets were paid attention to to reduce enlargement for reloading. It was reload-tested for 10 cycles.

...and yet you have concern for breaking the 55,000 psi barrier, something I do with regularity with Lake City formed to 223Ack.
I should expect it to be heavier and dimensionally thicker than say .221 or .17 fireball brass when we see it?

This same brass is used in SAAMI proof ammo at over 70,000 psi but member companies will not load this ammo over normal pressure guidelines. In my own hand-loading, I only load to what I have reason to believe is 55,000 psi.

I don't know how the thickness compares to 221 Fireball brass. I believe it holds 25.1 grains of water to overflow, if that helps.

Sorry about that.

And again, when I PAY for a item that I am told is in stock "especially a NFA item since the wait is so long" I expect said item. So shouldnt aac have done basic math and figured out the lead time on a product? Hey 0+0=0 and $0.00 ;)

Oh and on the remington barrels have you told customers that cases may not eject unless they also install a diffrent extractor? Cause there will be some pissed off customers if you dont, just sayin
