300 Aac Blackout (300blk)

[TCCrewchief76]

Let's not forget "fog of battle". Nobody's a perfect shot under duress. Ever wonder why it takes so many shots to put down a bad guy? Because not every shot makes it to target. That's just a fact of life. I need to know that my shots are gonna make it on target, and I know that if my weapon stops working, I'm in a shitstorm of trouble until I get it resolved. I think we could really divide the "types" of weapons in this discussion into "offensive" and "defensive" type weapons. I cannot think of a better offensive weapon than a truly quiet one when I want the element of surprise. If I'm engaged, I'm already behind the eight-ball, and I need to have a weapon that isn't gonna leave my ass hanging out to dry. Ideally, accuracy and reliability must go hand-and-hand, and luckily, I can get both.

All I know is that for more than a thousand dollars, is better be accurate and reliable.

I know that there is a copyright issue for different names ( 300 whisper/300/221 7.62 what ever) but can anybody give me the strait answer ? Is 300 blackout compatable with my Redding 300 whisper dies ....I already have a 300 whsiper that I am very pleased with on an AR platform and have a bolt gun in the works My gunsmith is waiting on a reamer from PTW .

Nobody can give you a "straight answer" because no one knows.

What he said.

The Redding is not 300 Whisper(R) but rather Redding's version of 30-221. There is no standard for 30-221 and so there is no way to know without comparing Redding's drawing to a 300 AAC BLACKOUT drawing. Only Redding can make that determination as only they have the specs for their die.

How about if somebody from say AAC published thet diminsions of the 300 blackout so we could all find out if we need more dies or to refinish chambers to make things uniform...everyone seems to be using political correct secret squirrel code instead of just saying " yep thats the same or no its totaly new" to my knowledge Hornady and Redding had been making 300 whisper dies and now Forester I think I read are making Blackout dies...........I am just trying to keep thing simple, I would like both my rifles to be the same ( I dont care what I windup calling the cartridge)

There was a 300 Whisper drawing made for CIP a while back that would have standardized every thing,any idea why that one wasnt adopted?
Rumor was that Mr Jones had failed to re-register the "Whisper" trademark and it was open season.

[rsilvers]

Most trademarks are not registered. In fact the TM symbol you see all the time specifically means a non-registered trademark. SAAMI never would have accepted Whisper as the name unless SSK provided a document saying it was free for everyone to use.

Also the name implies quiet, which means suppressed, and I think the future of this concept is primarily full power ammo. Time will tell when we see the split in ammo sales between subsonic and supersonic.

So why not name it 300 Fireball? Two reasons... One is that it implies bright flash of light and loud. The other is that there were too many wildcat chambers kicking around with that name, and using that name might be considered to imply that the ammo was safe to fire in all of them.

So a completely new name was needed.

[rsilvers]

The headspace of CIP 300 Whisper(TM) overlaps with 300 AAC BLACKOUT. The most they ever differ is by about 0.0004 inches.

There is more freebore in 300 AAC BLACKOUT, which was needed to allow for a 220 or 240 MK to be loaded to full magazine length and not jam the rifling. It also allows for higher velocity with any bullet, as you can sometimes use more powder before you hit the max pressure limits. Further, CIP 300 Whisper has a 3500 BAR (51,763 psi) max pressure and 300 AAC BLACKOUT is 55,000 PSI - though CIP does not measure the exact same way so it is hard to know how that translates.
