    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.

    I'm not really a rifle person, but the first thought that came to mind when I saw this thread is: .300 Whisper.

    I'd like to see a side-by-side comparison photo of J.D.J's .300 Whisper and this new .300 BLK.

    Sounds like a pretty cool round. It'll be interesting to see how it performs.

    Some comments from Bill Wilson:

    Got our first Wilson Combat 300 AAC BLACKOUTs together last Friday thanks to some good imput from rsilvers.

    Spent most of Sat and Sun on the range doing load development and accuracy testing. Shot over 700rds thru 4 uppers. Settled on the Barnes 130gr TTSX over 18gr H110, 2.160" OAL as my hunting load which gives me 2050fps MV out of my 11.3" SBR. So far I've taken 1 hog and 4 deer all with excellent down range terminal performance.


    Bobcat at 40yds, amazing based on the exit wound we had good bullet expansion.


    172# sow taken at 85yds, both with 130gr TTSX at 2050fps MV, one shot DRT with massive spine/lung damage on hog.

    It's like shooting a pop gun, minimal report and no recoil...................



    We shot several bullets into the hog in the am and recovered some bullets to see what kind of expansion we're getting.

    Bullets recovered after passing thru the shoulder area (12" thick) of a 172# hog shot from 75yds. We did not recover the TTSX bullet that killed her last night, it penetrated 19" and exited.

    Barnes 130gr TTSX penetrated the hog and approx 8" of water behind it, expansion is .502" at the widest point, 100% weight retention. We shot 3 more from 125yds and penetration was a little more, 1 went thru both the of the first two 5" thick water jugs and into the third, but expansion dropped down slightly to .479", .488" and .490". Load was 18gr H110, 2.160" OAL, MV was 2050fps.

    Nosler 125gr Ballistic Hunter penetrated the hog and approx 2" of water, core and jacket were seperated and both combined weighed 108gr, was suprised at the amount of penetration with this fragile bullet. Load was 18gr H110, 2.160" OAL, MV was 2075fps.

    Based on what I've seen so far I think the 300 AAC will be adequate for deer and hogs with the 130gr TTSX out to 150yds, which is about as far as I normally shoot anyway. The Nosler Ballistic Hunter should work fine for smaller hogs and deer, but I wouldn't want to stick one in a 200+# tough old boar. The Ballistic Hunter would be one heck of a home defense round................


    Pretty good silver boar taken at last possible shooting light tonight from 92yds with 300AAC/130gr TTSX, one shot DRT full penetration. Total kills so far since Sat. 1 bobcat, 8 deer and 3 hogs all clean 1 shot kills. Amazing how well this little cartridge kills with minimal report and no recoil....................

    Great. Another obscure as well as obtuse AR Wildcat round that will sell like chains in a prison. :whistling: Don't these companies realize that 99.99% of shooters who buy AR's don't even handload? :upeyes:

    This is not a Wildcat. It was submitted to SAAMI. Remington is making millions of rounds of ammo and retail on ammo is $12.99 a box MSRP - cheaper than 6.8 SPC.

    While I have to say that I am a proud American, we try to reinvent the wheel too many times. Instead of 5.56 Nato we should have adopted 7.62 X 39. Has the thump needed for jacked up terriorists and is a proven performer. Put a modern bullet in that round and it will do everything this new round will do.

    By the way, what was exactly wrong with 7.62 X 51?

    OK, I'll shut up now. :whistling:

    Is it safe to say that every 30 caliber microniche is now filled? Are we done?

    it might be a whisper. i've got a friend who was going to have a whisper made by a local gunsmith. he called J.D to get some techical data and was told that only he could make .300 whisper, that he had the copyrights to the name. so if he wanted the other guy to make his gun they would have to call it something else.

    For all intents and purposes it is essentially the 300 Whisper. The point is now you can buy a commercially made upper and buy ammo that is obtainable from a major manufacturer. It is no longer a wildcat. It is the same thing as the major ammunition companies producing the .338-06 or 35 Whelen. Sales should increase with readily available commercial ammo. Personally, I would like a politically incorrect 30-30. I live in CA and have a couple of grandfathered ARs. This round would be a lot more ethical for deer hunting. And for all those antis that say only hunting guns should be allowed, well now it is a deer gun and i can rub it in their faces. All I need is some ammo with Barnes all copper bullets and even the CA Condor lovers will have to eat a $!&% burger. :tongueout:

    The 300 Whisper name is a trademark.

    The 300 AAC BLACKOUT has a longer throat and so can be loaded to a higher velocity - sort of like how 6.8 SPC-II compared to 6.8 SPC, or 5.56mm compared to 223.
