Gett'n kinda bored of the 223. I don't really have a purpose in mind for it....just something different that can be shot cheaply and in quantity. I also suspect that with the right bullet, it could be a decent small/medium game hunting round.

What do you think??

Well I just read about this caliber and thought it over good and well they made a brand new 30carbine. Why some of these new calibers come out I don't know same ballistics as a 30 carbine and a 300 whisper. Why someone just hasn't made a AR platform to shoot 30 carbine I don't know it AR's have enough bolt throw to where you could use longer spister shaped bullets instead of the 100-110grainers that are normally used. It seems that nothing they come out with besides the the 45 cal and bigger stuff ccually develope more energy then the 5.56 just throws a bigger bullet if I was going to go with a ifferent caliber in a AR there would only be one choice for me and thats the 6.5 grendel i seems to be the only one that accually shows superior energys combined with a good trajectory. Just my two cents.

Go with the 6.8 spc. Just make sure you get the spk II chamber and a 1:11 twist. Look at AR Performance, Bison Arms, Stag and Delta Company Arms. All sell great uppers for the AR and are great quality. If you want a 300 blackout it really shines in subsonic loads.

the 6.8 spc is a killing machine. I kill deer and hogs with it and have a bunch of my friends with them now and it downs the game!

got to agree. Unless your looking for a silenced gun the 6.8 or 762x39 are better choises for deer hunting.

I have experience with the .300 whisper 220 gr. and 240 gr. subsonic are real quite,
the 125 supersonic does 2300 fps from 16" barrel. If you want more fps the wilson
7.62x40wt is longer and still works in AR platform. An AR, to shoot both you really need
to have a gas regulator to switch to be able function the gun with both. Wildcat stuff
starts to get real expensive and they say you should not make .300 whisper from .223
brass because of thicker walls; the Wilson cartridge you can.

Thanks guys....like I said....I'm just bored and want something different. I have no intention of suppressed anything and, knowing me, I'll probably always use it in supersonic. Just thought it looked like an interesting cartridge. 6.8 also fits the bill.

What I have read is the 30aacBO is more like a 30-30 , but I have not shot one. The 30 AR from remington would be a nice gun .
The 6.5 Gre... seems like a better long range shooter over the 6.8 SPC. I looked into the 6.5 before getting a 6.8 but settled on the 6.8 . I like it but cheap to shoot isn't one of its best features .

Only if you compare a 6 inch 300 BLK barrel to an 18 inch M1 Carbine barrel.

It is very, very far from an M1 carbine if they both have the same 18 inch barrels.

M1 carbine is 1990 fps from an 18 inch barrel with a 110 grain.

300 BLK is 2450 fps from an 18 inch barrel.

The M1 carbine would be 383 ft-lbs at 200 yards. The 300 BLK would have that energy at 525 yards.[/size][/font]

Why not more major brands like LWRC, Barrett, or Ruger? There is nothing wrong with 1:10 twist.

7.62x39mm does not work well in an AR15. Also, Remington 125 grain Match ammo in 300 BLK has 16.7% more energy at 300 meters than even the hot Lapua 7.62x39mm. And 6.8 costs a lot more for brass and ammo and requires special magazines and bolts.

That is all true of 300 Whisper(R). It is also the things that were fixed by 300 BLK. 300 BLK is not a wildcat - SAAMI standardized it.

300 BLK brass can be made from 223 brass, as the neck is a few thou larger in diameter than the previous wildcat version.

Also, 300 BLK brass is real cheap now:

http://www.midwayusa.com/product/2923270375/advanced-armament-co-aac-brass-300-aac-blackout-762x35mm-primed

Also, adjustable gas being a requirement is not true with 300 BLK. Subsonic and supersonic shoot in the same gun with no adjustments needed and both will cycle within Colt M4 factory specs.

true just like folks says th 300 blk is right there with the 7.62x39 even though it falls quite short of there as well. As far as 300 blk to 30 carbine it's accually more of 2350fps to 2100fps 250fps in light bullets don't mean diddly. So Yes It's just a new 30 carbine. Like I said before why they are making all these new cartridges that really don't fill any gaps is beyond me.

It is like a new 30 Carbine, except at 190 yards it has the velocity that an M1 30 Carbine does at the muzzle, and it works in an AR with 30 round capacity.

the problem with most 762x39s are magazine related not gun related. By cproducts mags install wolf extra power ak47 springs in them and most will run great. My bushmaster eats any handload or factory ammo including wolf just as reliably as any of my .223 ars. the great thing about it is i can buy wolf ammo go out and blast away and for once in my life not have to worry about picking up brass and even if i buy reloadable ammo its a heck of alot cheaper then the others. Balisticaly you can count hairs but all three of them are about equal on deer out to 200 yards. No deer is going to know the diffence in which hit it and any of the three have enough power for 200 yard deer shooting.

When the 7.62 x 39 was first offered in the AR platform there were feed issues....I'll agree with you there. The feed problems that initially existed, only lasted for a period of several months.

That is not the case today, and the 7.62 x 39 operates just fine in the AR-15.

Dezynco · « **Reply #16 on:** December 23, 2011, 01:17:19 AM »

I just had to pipe in....
I've killed two very niced sized deer with my 300 Whisper. However, I wouldn't consider a 30 Carbine to be an adequate deer hunting cartridge. The design of the 300 Whisper is very efficient, making the most performance from a very small case that is possible. The slight shoulder allows for a very efficient powder burn, thus allowing the bullets to develop as much velocity from the very small case. That can't be said for the old 30 Carbine, which is essentially a straight-walled case. I'm not knocking the 30 Carbine, it's one of my favorite cartridges in my Contender barrel, lot's of fun to shoot.
The 300 Whisper (or 300 Blackout) with 125 - 150 grain bullets give performance that is just this side of the trusty old 30-30 Winchester. I'm confident with my little carbine out to 200 yards. It's certainly not a long range cartridge, but that's where the 6.8 SPC, the 6.5 Grendel, and the 300 Olympic SSM come in. Also the 300 Whisper (Blackout) are very cheap to shoot because the brass is cheap (yes you can use 223's to make the brass) and they require such a small amount of powder to get the job done.
It's always hilarious to watch as the manufacturers come out with these "new" cartridges. Everyone goes nuts over them and for a while you can't get your hands on a gun or any ammo for them. The 300 Whisper (and all it's variants) have been around for years, and us old dudes already know it's usefullness and it's limitations.

You can go to the 300 Blackout Forum and get answers for all questions.
My Blackout is very accurate, one inch groups at 100 yards with two different 125 grain bullets, cheap and easy to reload, has functioned with all bullets to 220 grain subs, mild recoil and would make a perfect home defense carbine.
My suppressor is on order and should be in next week, then a 5 month wait for feds to send tax stamp. Only then will I get full use of the weapon. With special bullets available the subsonics will make great 100 yard deer cartridges for hunting in urbanized areas.
Does this cartridge do anything that another cartridge cant do, answer is no. It will change calibre in an 15 platform with a simple barrel change or just get a dedicated 16 inch upper or get a 11 inch short barrel upper, suppress and enjoy.

Essentially, yes they are the same. The cartridge shares all the same dimensions, but I think the chamber throat is slightly longer in the Blackout? I see now that most of the "Big Names" are chambering their rifles to use either ammo. I'm pretty sure you can use Whisper ammo in the Blackout, but not the other way around for some of the older barrels. I'm not really sure about that, but I've read in more than one place that it does not any difference, and some guys are using Blackout ammo in their Whispers with no issues.
