    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?

    That's what I was about to ask, it looks very similar to the .300 whisper loading.

    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.

    Easy; it brings AAC money instead of SSK. ;)

    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.

    Man, hardly have any posts and I think I'm a thread killer. Every time!

    Yeah, just looks like an underpowered 7.62x39 to me.

    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.

    Looks like AAC/Rem. is taking a peice of the Pi.

    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.

    What can be said that hasn't already been said?
  20. 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.
