Just saw this on AAC's Facebook page. Seems like the caliber we've all been waiting for. Hard hitting, quiet, and seats 30 in a standard GI magazine. Comes in 123gr, 155gr, and 220gr flavors. This thing is going to be the HEAT like Bobby Deniro! Seriously, here are some links:

What do you think? I'm downing a pitcher of this AAC/Remington Kool-aid right now! First thing Monday morning, I'm calling Mers at AAC to see about getting an upper and some ammo.

If you live in a state that allows SBR and/or suppressors, and you have the funds to buy them (tax stamps and all), it looks very promising.

Otherwise, it's a novelty.
 
I don't think a 16in upper in .300blk would be any more of a novelty than a 6.5 Grendel or 6.8spc. In fact, with the backing of Remington/AAC, this may become more of a common round than either of them.
 
So basically this is just a 7.62x39mm tweaked for an AR? Am I missing something groundbreaking here?

ETA: The ability to switch between subsonic loads and supersonic loads and maintain good performance in both seems promising, but what about the platforms? Will an autoloader cycle the subsonic and supersonic loads without adjustment?

Yeah, I may have been hasty. But without the benefit of an SBR or a suppressor, the cost per found better not be too high, maybe 75 cents/round as a cutoff for general purpose ammo (FMJ or PSP). Any sense of the cost? Even 6.8 SPC costs a bit much for me to adopt it.
 
Looks a lot like a 300 whisper. What does it do that the whisper doesn’t?
 
I'm wondering why the round wasn't given a couple tenth's more neck and case capacity. It certainly could stand to have a bit more performance available to extend it's range beyond 200yds.
We already have the 300 Whisper with similar design and ballistics.

It is essentially a 300 Whisper. It is exciting to see a major manufacturer backing it. If they can produce the ammo at a reasonable cost, it may really bring the caliber into the mainstream.
 
It's ballisticly equivalent to what? 7.62 39?

If it's meant to be a replacement cartidge for the military it better be able to be shoot a decent distance. I saw that it touted it's short range capabilities, but nothing about reaching out. We are an Army based on marksmanship.

One of the gripes I had in Afghanistan is that our unit all had M4's. My last tour I had a SDMR modified M16A4, slightly different ammunition but I was able to reach out much further than the M4. Unlike in Iraq, we were fighting mostly in mountains, hills, and fields. Quite a few times we had to adopt Marine tactics of two rifle suppression while the rest of the squad rushed- just to get within a reasonable range. Wouldn't have been an issue if we could have reached out a bit further and picked them off.

Meh -- I don't think it gives sliced bread a run for its money, and militarily it's certainly not going to go any further than the ballistically superior 6.8 Rem SPC got.
 
Man, hardly have any posts and I think I'm a thread killer. Every time!

Not hardly! You echo what's been happening for nearly 50 years. There's only so much you can do to improve the 5.56 ammo and platform.
Sometimes you just need a bigger gun.

If I was SSK, I'd still tap them on the shoulder about my part of the proceeds. They are totally robbing any claim to design and development.....it is so close to the .300 Whisper, it might even chamber in weapons made for same. I see a lawsuit! Ballistics MIGHT be a little hotter, but then again, they might even be overrated.

That is probably the solution. However, I will say. You hear a lot of people Beltch about the 5.56 at, lets say, knock out power. i didn't have a problem. If you hit someone in the off hand with a 30-06 they still have fire capability.

I spent most of my time in Afghanistan, with only a two month lay over in Iraq. I was SsGT in the 82nd and we didn't see jack in Iraq. Some patrols and no assault missions, so I don't have much experience in that field.

However, when my company first landed in Afghanistan with M4's, it was already pretty obvious it wasn't a good idea. The Marines kept the M16A4 for good reason, it's a rifleman's weapon, the M4 is meant for small time work. I hated the M4 on my first tour. And was glad I had the SDMR M16A4 on the subsequent two. It wasn't the M14, but I reached out a good 800 meters, while most of my squad was bricked at 300.

By the time I was Ssgt I had to give up the SDMR to a Corporal, and I carried the M4 again. We need a rifle in Afghanistan, not a g-d sub-machine gun. The 5.56 suffered some range difficulties, but not compared to the 7.62 they were using. The issue was our rifles. And M4 is a house clearing weapon, not a battle weapon. I bet it was fantastic, if not a bit late, in Iraq, but had no place in the theatre I served. As my experience the 5.56 had great elimination, just pop them twice. But that should be followed no matter what round.

As Ssgt I had to take charge of the battalion as lead officer, and then another three months getting the actual CO used to operations. I professed to my soldiers to become proficient in semi-auto because full auto was completely wasteful. Especially as desolate as we were. We couldn't even get batteries for our NV. And as far as I know he continued such. We have accuracy and training on our side, where as they do not. Our deficiency was range without an intermediate rifleman. We took care of that with the SDMR, but even then we faced a times where we had to push with undue possible loss.

I am R&D Director at AAC, and the project lead on this.

Everything 300 AAC BLACKOUT does, 300 Fireball, 300-221, and 300 Whisper were capable of doing. But there was no SAAMI standard - and there were too many loading manuals with data inappropriate for the AR. We created a standard, released it for anyone to use royalty free, and introduced it to SAAMI. We have a metric ton of affordable ammo coming - lower than 6.8 SPC prices.

So truth be told, it honestly has not military application... I've seen the add saying it could be "the next big thing," but being a recently discharged soldier I see nothing that holds merit. 50 yrd clearing is not going to mean anything. What I want to see is what the ammunition can do at 300yrds at least.

Do you really have to post the same thing in every forum? "...be the HEAT like Bobby Deniro" ??? I don't know what to say. :eek:
