Question:

Is 300 AAC BLACKOUT a standardized version the 300-221 Remington Fireball Wildcat?

Answer:

300 Remington Fireball wildcats are typically capable of doing everything that 300 AAC BLACKOUT does, but there was no SAAMI standard and that prevented major companies from making products for it. JD Jones's pioneering work, which he Trademarked as 300 Whisper®, has helped bring attention to the concept of a 300-221 Remington Fireball based solution as an excellent 30-cal cartridge for both supersonic and subsonic performance when used in the AR platform as well as in bolt guns. 300 AAC BLACKOUT is a standardized version of the 300-221 Remington Fireball Wildcat, and has been submitted to SAAMI.

Question:

Can existing loads for 300 Whisper®, 300-221, or 300 Remington Fireball be shot in 300 AAC BLACKOUT guns?

Answer:

We did not purposely make it incompatible with 300 Remington Fireball, but because there was no standard for the 300-221 or 300 Remington Fireball, and because the 300 Whisper® is proprietary and unpublished, that is not something we can decide or guarantee. The maker of the ammo must ensure that their ammo meets all of the specs for 300 AAC BLACKOUT in order to use it. Even if it is safe to shoot, it may be too long to work well in AR15 magazines due to the magazine 'rib', may have a powder inappropriate for AR-based 300 AAC BLACKOUT firearms, or may have a bullet design which only feeds in single shot firearms. We recommend ammunition specifically designed for 300 AAC BLACKOUT.

Question:

Can existing rifles in 300 Whisper®, 300-221, or 300 Remington Fireball shoot 300 AAC BLACKOUT ammunition?

Answer:

We did not purposely make it incompatible but the maker of the firearm or barrel needs to verify and guarantee that their chamber meets the specs for the 300 AAC BLACKOUT chamber.

Can you use 223 brass to load for the 300 BLACKOUT and not have to trim the OD of the neck?

[300Blk]

Most likely yes. But of course measure the neck.

Are there plans to make a Breakout Mount for the 300 AAC upper?

Can you use the 30 caliber 18 tooth brake without barrel profile work?

Can you use the 30 caliber 18 tooth brake without barrel profile work?

It will work with any of our 7.62 mounts threaded 5/8-24. (except SCAR-H MITER)

Is the 300 Blackout the reason for the non-mount flash hiders in 7.62? (why only 1/2" x 28?)

I wonder if that is an error.

I wonder if that is an error.

I'm thinking it might be.

I wish they would make a .30 cal non-mount Blackout in 5/8" x 24.....
