I like you am a man of many calibers. But there seems to be a lot of animosity over on the 6.8 forums.
Because they want lower priced 6.8 ammo.
My prediction for 300 BLK - within 6 months you will be able to buy 300 AAC BLACKOUT ammo for $9-$10 a box.
Within 3 months there will be uppers for sale for under $300.
Within two years (three years after introduction), it will be the #2 centerfire rifle cartridge for the AR15. There are already about 65 companies involved.

I’m just giong to ditch my 6.8 dream. The gun is getting turned back to a 5.56 within a couple months. I like everything I see going on with 300BLK but I wont be jumping into it until I see the rsilver’s prediction coming to pass.
I would have been happy to see affordable 6.8 ammo come out, but it’s nice to see actual effort in the industry with the 300BLK; let the 6.8 guys cry :cray:
I don’t mean to drift the thread but I think the 6.8 guys are just as much to blame as any one group for the “failure” of that cartridge. Those guys can’t even agree on which chamber is the best (there appear to be three different drawings) and can’t accept anyone’s evidence that one chamber isn’t necessarily better than another. Same goes for rifling twist and primer pockets.
And I like the 6.8 and have two rifles chambered for it.
I guess I can wait just a little bit longer for an upper chambered in this round. Would love to get an upper for 300 bucks in any caliber other than .223.
Yah don’t need to wait because even if I am incorrect and it does not happen, you can just replace the barrel with a 5.56mm one and be back to 5.56mm. Same bolt, same magazines. There may be some risk, but the cost of changing your mind is low this time.
I was hoping to have a .300 set up before this years deer season, looks like I’ll be using my carbine to hunt next year though. Bills got in the way.
I am really looking forward to shooting and testing a quality .300 upper. I think this may be a really great idea for a patrol rifle caliber as well.
I’m a 6.8 guy and I think it’s fine. The 6.8 children won’t like it.
good to hear this;)
What was the test barrel length ?
16 inches.
When we had to decide on the SAAMI standard barrel length, the normal thing to do would be to pick 24 - as that is the standard rifle test barrel.
But who uses 24 inch barrels anyway - for this or any predominantly AR cartridge?
So we made 16 inches the standard barrel length so that the published specs would be attainable in most actual rifles. Novel concept.
Is there any significant performance increase with a slightly longer barrel like an eighteen or twenty? I’d guess not given the powder charge in the case. But I’m still curious.
Yes, longer barrels give significantly more velocity. We are just lucky that for this cartridge 16 inch happens to be the sweet spot. We can rationalize it all we want, but the sweet spot for 223 is around 24 inches, with 20 being on the short side, and 16 being a big loss of efficiency (and less than 16 being horribly inefficient).
I really hope this comes to pass. It would make it easier on the regular guy to pick up some ammo for classes, matches, or just range time. Which would all be towards making it more popular and needing more uppers, etc.
==========================================
RSilvers,
I apologize for my ignorance but I have a few questions.
- Is the “barrel” all that it takes to shoot the 300?
- Uses the same H Buffer and Buffer Spring?
- Does the 300 use a carbine, middy, or rifle gas system?
That’s it.
Thanks

Do you have numbers for shorter barrels ?
I’m interested in the 12" Noveske barrel. I’m curious what the velocity loss would be.
It has to happen, because this UMC, given the custom bullet, and NATO-hardness annealed-neck properly head-stamped brass will be $10.50 to $11.50 at places like Cheaper Than Dirt within a few months.
So all of the ammo made from reformed brass and less-than-optimal pulled bullets will have to be at the very least $2 a box cheaper for anyone to want to buy it.
The Remington Match ammo that is 2220 fps in a 16 inch barrel is 2050 fps in a 9 inch.
Yes, just a barrel.
Carbine gas for 16 inch and longer barrels.
Pistol gas for under 16 inch barrels.
At least for DI. Piston may differ.
