Headspace is allowed about a 0.006 range, while the throat in 300 AAC BLACKOUT is about 0.050 longer than in 300 Whisper(R) (about the same difference in the 6.8 SPC-II vs the 6.8 SPC throat).

300 Whisper(R) is proprietary but JDJ still has a fixed set of drawings for it. The 300 AAC BLACKOUT has a longer throat than 300 Whisper, just as 5.56mm does compared to 223.

All of the chambers you just mentioned meet 45 Colt SAAMI specs as an allowable variation. The 300 Whisper(R) does not meet SAAMI specs for the 300 AAC BLACKOUT because the chamber is outside of the range allowed by the SAAMI drawing. Likewise, 223 does not meet the dimensional specs for 5.56mm.

That would depend on if they are within the specs for 22lr.

Thank you rsilvers for being professional about this.

Proven Track Record
Pioneering work by JD Jones with the 300 Whisper®, and others with 300 Fireball and 300-221, have proven the concept.
Perhaps the press should mention it more.

I stand corrected, rsilvers. Thank you for the citation. I had not seen the pdf of the media kit.

I would assume mostly/only the media has seen the kit as its a "media kit".:wink:

Personally you can fire 300 whisper/wtf ever in the 300 BO , and so since I do not buy factory ammo I am fine with this since I will still buy hoser's brass, and get my actions barreled by spook, and dont buy AAC or Remington as I dont care for them for personal reasons.

Furthermore, in all my 300/wtf ever rifles the chambers are within spec of the 300 BO so I guess thats a good thing. After thinking of this for a while I have come to the conclusion that whatever rem/aac says about pioneering this cartrige basically doesnot matter because everyone knows that they only backed this cartridge because, 1) they are remington and have deep pockets 2) to make money 3) to try to get mil/le to buy into it 4) most the leg work was already done by people who try to make a living doing this.

I amnot trying to put remington/aac/cerberus capital management, l.p. down just simply stating the facts as I see them. I just hope the small operation smiths still produce rifles in 300/wtf ever

They are, look:

I said SMALL shops, and was referring more to the fact of the gun world simmilar to this, Joe buys a by remington called the aac in 308 because it's pre threaded for a suppressor instead of having one done custom because he bought it for $650.00 from a local retailer. In THIS world, why would someone spend 200-300 extra for a custom rifle in 300/wtf ever when he can buy one for $650 from a local dealer. See my point is that it will eventually cut out the local smiths who build these rifles for people who want them and will cost them "the smiths" in the long run.

If you dont belive me that your precious little blackout will sell for $650ish eventually then here is remington/aac in 308 that just sold for $600 and I expect the BO will be in the same price range unless rem keeps the volume low to raise the price.

McGowen is more than a few people?

But yes, the days of having to pay $1200 for a bolt action 300 Fireball are soon over. There will be Remington Model-7s and maybe CZ rifles for much less. People who want custom rifles can of course still commission them, but it won't be the only option.

I like the idea of an off the shelf bolt gun in 300BLK as long as its the same price as the other basic rifles on the shelf like any 308,243, '06 and 270...:nanabang:

Mike keep in mind the sub industry out there making all the " blue light special's " shoot better than they did when they left the factory.

I'm not sure why... but the phrase " you get what you pay for" ... comes to mind.

Yep, and until Remington starts putting PacNor and Shilen barrels on their rifles, they'll sell for the $600 range (or more), and won't be as consistent as when going the custom match-grade barreled route. I now own two PacNor barrels, and while I haven't shot one of them yet (waiting for my State to get it's act together), the one I have shot barely makes groups over 1/2" with 10 shot groups with ANY load I've put through it so far...

BTW, I'll make a shameless plug here for Spook, as his workmanship is OUTSTANDING!
