300 Blackout Round

[Tweety Bird]

I started another thread about a neighbor's AR chambered in 300 Blackout. Poor kid is having nothing but trouble with it.

Does anyone know anything about this round? I sure don't. In fact, I hadn't even heard of it until Riley bought this AR last spring and asked me for some help trying to get it running right.

Just trying to learn a bit about this, why it was developed, what are its advantages and disadvantages, etc.

This serve you better in the Factory Ammo and Reloading Section?

Makes no difference to me either way ...... just asking.

I know there are two popular types of ammo. Fast and sub-sonic.

The idea is to shoot a 30cal bullet in a basically stock AR platform. The only difference in the rifle is the barrel. :D

Need a more detailed description of the problems. "Nothing but trouble" is not even a starting place. I've "assembled" AR's in several calibers w/o issues but by no means consider myself an expert. Give me some specifics and I'll try to diagnose the difficulties.

I am sure someone will come along and help you but if not go to http://www.300blktalk.com
Hope this helps and good luck.

Thanks.

300 Blackout is an under performing 30 cal. dog.
That is all I know which is enough. ps

 

[gramps]

www.thehighroad.com, was where I first heard of it some years back. Of course it was touted as the best thing since bread. It didn't do anything for me. Good luck.

Been shooting this recently invented round since the mid-late 90's. :lol:


Back in the 70s people loaded 30/223 in the contender but the pressures could be an issue if you weren't careful. Somewhere along the line someone did it with the shorter 221 fireball case.

Then in the 1990s JD Jones invented it and called it the 300 whisper.
Then a few years ago AAC invented it and called it the 300 Blackout.


It's a very efficient round, works real well in stuff like the contender and short barreled AR's. Performance in rifles is sub 30-30 level, so it's nothing amazing ballisticly. Lots of people buy them thinking it's something it isn't.


I've owned a "300-221", two "300/221"s , two "300 fireball"s and two "300 whispers" (and all of them the same damned thing) but no 300 blackouts. That's AAC's claim, they "standardized it". Uh huh. :roll:

Yeah... and I invented the .22 blackout. A 300 blackout necked to .22 ;)

CAS you forgot the .30 Super slow. Jim Rock's answer based off the .32 H&R another mid 90's invention. I have some very interesting bullets from that excursion. Something I see mentioned and then"hidden" when the Blackout guys get talking. I spoke with JD about this. He was all kinds of talkative until I mentioned this.

The 300BLACKOUT is a phony ersatz copy of the original 300WHISPER cartridge developed by J.D.Jones twenty two years ago. Since the R-P thieves were too lazy and/or stupid to develope their own 30CAL subsonic round they stole J.D.'s but missed all the importent little nuances that made it all come together and work like a charm. I've shot the original 300W and the first AR 300W and neither weapon missed anything out to 200 meters and were so quiet we had to warn each other not to walk in front of the shooting stand.

Could you link to this 'other thread' I would like to see where it goes. :D

edit to add. Here is the other thread. http://www.rugerforum.com/phpBB3/viewtopic.php?f=1&t=214934

My son was going to build an AR in .300 BLK and I said why not get a Mini 30?
The only advantage I see is you can use standad AR mags...and if you also have an AR in .223/5.56 this may cause an "oops moment". And .300 BLK is spendy. .30-.30 and 7.62x.39 is readily available and less spendy.

 

[Mike Armstrong]

I understand why somebody (even a soldier) might want this round in an AR.

But for the rest of us I think the .30-30 is a lot better choice if you want to play around at the low end of the .308 bores. More flexible (up or down in power), cases are easy to find (sometimes "literally" so they don't become litter!), and it works great in single shots like the Contender Carbine.

With a good barrel and the modern bullets now available, it can be a very effective and accurate round, from paper punching to piggies. You can even find nonlead bullets for it! For a handloader it is now a very versatile round.

I think Riley bought this rifle because he thought he was getting a good deal on a custom-built gun. He's young and still learning. He says he got a good deal on it and it has a lot of "tacti-cool" features that might appeal to a 19-year old, like a free-floating foregrip, flip up sights, a heavy, fluted stainless barrel, etc. In my opinion, the only thing he missed on was the chambering. He's also learning a lesson on ammo costs.

He's a real nice kid, though, and comes from a very fine family, so I'm going to help him as much as I'm able. It's just that I know absolutely nothing about the 300 Blackout (not that more knowledge of it is going to help me here; I'm just curious more than anything).

If he can ever afford it, I'll probably just recommend that he put a new barrel on it and use .223/5.56 ammo. I think the parts support would be better and the changeover would be easy since he could (probably) use the same BCG and he could keep using those "evil, high capacity clips" that he currently has.

 

[clbshooter]

If your young friend has access to a computer he needs to research this on his own. I think it will help him understand the do's and dont's of this round. If he decides to go to 5.56 he can probably trade the .300 barrel for a new 5.56 barrel as they cost a lot more.

good luck

Wasn't the .300 Blackout/Wisperer developed for suppressed rifles? If not using it for that, it seems a lot of other rounds could do the same cheaper and easier.

 

[DGW1949]

It seems that your young friend has been expossed to some rather important lessons that over time will become priceless. Hopefully, he has learned from them. In the mean time, ya'll might give some thought to getting the gun to run right and then sell the thing, or trade it for something which is a bit more conventional, a bit more usefull, and cheaper to shoot.
In spite of the hype, I've yet to see a 300 Blackout which turned out to be all that and a bag of chips....if ya get my drift.

In the mean time, I'd be taking a hard look at the gas port relative to it having the correct orfice size and alignment. I'm no AR expert but my guess is that something there aint right.

Hope this helps.
