Is the 300 AAC Blackout a meme?
It took about 60 years for ARfags to discover 7.62x39.
everything is made into a meme, weapons and ammo are just that, weapons and ammo. Autists on here make shit into memes. So as an answer, no. 300BLK has it's place in modern firearms, people like it and people don't. Whatever
>>29548343
Yes, until it's adopted by a major military power and establishes itself as a caliber with permanent staying power. It's just as likely to become another 6.8, .458, .50beo or any other meme bullet and fall out of fashion just as quickly as it appeared.
>>29548343
If you have to ask, the answer is yes.
>>29548393
are you a meme
>>29548359
It does 7.62x39mm better while fitting in an AR.
Making 7.62x39mm ARs has usually been a headache, and you basically need an AR-10 sized receiver and bolt because of the wide case, otherwise the dimensions on the bolt-head gets too thin. It will also require a special lower with new magwell.
.300BLK can give you all of it's functionality and more, all you need is a new barrel, everything else works on .223 parts.
>>29548386
It might not see widespread official adoption, but it's garnered enough civilian market attention that it's gonna stay, it's got good applications.
>>29548393
>>29548418
confirmed for meme poster
>>29548343
if by a meme you mean is it popular? Then yes. If you mean is it all hype and bullshit? Then maybe... It is good at what it was designed for. Supressed SBR with a heavier bullet that can use more standard 5.56 parts.
>>29548343
300 Black out comes sub-sonic so it works with supressors and achieve good ballistics with a shorter barrel than 5.56 so it's actually pretty cool, all you need is a barrel and bolt and you're all 300 blacked out. Uses 5.56 mags and everything.
>>29548603
Grabbed by a goblin
>>29548343
memeout is pretty fucking great, no regrets at all
>>29548386
Where have you been for the past 4 years? It's here to stay and just becasue of your autistic definition of needing to be adopted by a military powers shows that you are a fucking noguz little shit who gets all his info from Call of Duty.
Why is /k/ flooded by idiots that call everything they don't own or like a meme?
Fuck off to /b/ already.
>>29548343
Nope, it fills a few niches (suppressed firing, hunting with an AR) very well while requiring minimal special parts.
>>29548642
>300 Black out comes sub-sonic
No, it CAN BE LOADED as sub-sonic without compromising reliable cycling, which is more than what you can say about 7.62x39mm
Lots of standard loadings are sold as regular super-sonics.
>>29549243
Isn't it amazing? I think it'll make a great regular carbine round, while .223 is great from longer barrels, .300 makes up for it's deficiencies from short ones, while being easy to suppress.
>>29549982
You can use a .223 AR to hunt too, people have used .223 to takr deer for decades.
Of course, it's not quite ideal to suppress.
>>29550013
>You can use a .223 AR to hunt too, people have used .223 to takr deer for decades.
A lot of states have laws requiring 6mm or bigger rounds for hunting, so .300 Blackout gets around that problem.
>>29550063
So does .277WLV, which has more muzzle energy than .300BLK.
>>29550013
>hunting with 5.56
Not in Virginia. .30 or bigger IIRC.
>>29550063
>>29550092
Oh yeah, I forgot about that.
Shit, wasn't it Delaware that only allowed shotguns?
>>29548343
No OP, it's a cartridge.
It's a terrific example of mindless consumerism in the gun world though.
>terminal ballistics

Valid, but most people don't seem to end up suppressing it.
>>29550178
>At 4x the price of x39
See >>29548580, you get that with a lot of conveniences.
Also the cost is gonna drop as it gains traction

We'll see how the Hearing Protection Act fares.
>worse barrier penetration than M855
Give it a steel tip or mild steel core and you're in business.
>>29549982
>hunting with an AR
Doesn't bother me at all if it's all someones got and wants to go hunting, but buying a .300blk upper for hunting triggers my autism heavily. That's just fucking stupid.
>>29548580
> .300BLK can give you all of it's functionality and more, all you need is a new barrel, everything else works on .223 parts.
lmao
300Blk fags actually believe this
If you are going to suppress it, it is very optimal for suppressing 30 caliber bullets. That's pretty much it.
>>29550083
Yeah, but that's a super obscure round with limited/no factory made options. With .300 Blackout, you can buy a .300 Blackout barrel and stick it in a regular unbarreled upper or just buy a prebarreled upper for less than $300 dollars.
>>29550178
>Valid, but most people don't seem to end up suppressing it.
Yeah, believe it or not, most people don't want to go through the hell of NFA bureaucracy.
>>29550217

>>29549982

>>29550213

You literally only need a barrel, the bolt-carrier, bolt, and gas-tube is 100% the same.
>>29550216
Yeah, it's basically 7.62x39mm but way more efficient.
I'll make a .300BLK AK to spite you some day.
>>29550288
Some rounds are easier to handload than others.
.300BLK is easy-modo, for instance
>>29550337
>I'll make a .300BLK AK to spite you some day.
IIRC, some Bulgarian company actually did do that.
>>29548343
Neat concept but jews gonna jew with that high as fuck cost per round inb4 hurr reload
Balistics wise it's a 7.62x39 so might as well use a cheaper, more abundant in a vastly superior weapon design anyways
And lastly which is always .300cuckout hardliners favorite is muh sbr subsonic suppression. Oh you mean something that applies to only 10% of gun owners who have to sign their 4th amendment rights away and create unnecessary paper work just to let people use or transport all for a .30 cal subsonic round that has the same muzzle velocity and trajectory as a .45acp? lol na I'm good m8
It's a round that's only good for sbr suppressed rifles so if you want to give uncle sam $400 to sling lead ballistically identical to dot fuddyphive or a 70 year wwII cartridge go for it
>>29550470
>all this meme in one post
>>29550470
>Jews gonna jew
Its new and getting cheaper. Shits expensive when it's not just surplus.
>ballistics wise
it's more efficient and has access to better projectiles.
As a bonus it uses standard parts, so no special bolt carrier,no God awful mags, no worrying about baffle strikes. .300blk isn't about shooting a bunch of cheap ass steel case.
>>29548642
Don't even need the bolt, it uses the same bolt as 5.56, just need a different barrel.
>>29550470
>same muzzle velocity and trajectory as a .45acp?
come on at least meme with some subtlety.
>>29550162

>>29550213
300 blk ar15 is great for hunting hogs.
>>29550162
Delaware allows shotguns up to 10gauge. You can use centerfire on groundhogs, foxes, and coyotes. Deer is just shotguns, blackpowder, bows, and hunting revolvers
>>29550213
should i give this 300blk and go hunting with it?
>>29550470
You should stop posting.
>>29552120
AK47 does it cheaper, and mo betta too.
>>29548343
The only reason 300BLK exists, is because NATO cant go using 7.62x39 as an official ammunition, and 5.56 sucks dick for suppressed.
>>29553212
>is because NATO cant go using 7.62x39 as an official ammunition
NATO countries have used that cartridge and the 7.62x54r, the issue with x39 is that it's dogshit to suppress and doesn't fit in a .223 rifle, see: >>29548580
If I'm picking between a clunky fucker of an AKMSU in x39 and an M4A1 or Mk.18 with a .300BLK barrel, I'm gonna pick the AR because it's objectively better as a rifle, it can do all of the same things when in .300BLK and more.
>>29552393
>300blk
that's a pistol ar puznuts.
>>29548343
It's a meme so far as AR fags forget about the existence of 7.62x39.
>>29553212
>AK47 does it cheaper, and mo betta too
not scince 2010ish, you stupid faggot. Look at prices for a decent AK you'll be spending close to 500 for a fucking WASR
>>29553447
try to shove x39 into a fucking STANAG you god damn nogunz faggot.
>>29553447
Have you ever tried to make an AR-15 in 7.62x39mm? There's some dimensional problems that comes with that territory.
.300BLK fits snugly in a .223 gun without any special work or proprietary parts, it only needs the new barrel. Also it does everything the 7.62x39mm can do and more.
>>29548343
Well considering it has caught on quicker then shit like 6.8 SPC and 6.5 and can be found for like 12 bucks a box it maybe is a meme? I dont know seems like a cool round
>>29553697
HMG made an AR lower for 7.62x39 that accepta AK and PMAGs but is expensive
>>29553871
Yeah but you're looking at a lot of non-standard parts to have an even remotely decent weapon, as stated earlier, you pretty much HAVE to use the AR-10 dimensions as a starting point, trying to fit a 7.62x39mm gun in an AR-15 receiver is an absolute hell of bullshit, reliability will be shit and the bolt WILL break.
The CMMG Mutant (and a few others) works because it's redesigned around the cartridge and magazines, it has the necessary dimensions, instead of a bunch of wonky "solutions"
Consequently, they're quite expensive and share few parts with an AR-15. Perfectly alright rifles, but their expense defeats the savings you make on the cheaper ammo.
With .300BLK you bypass a lot of this shit, sure, the ammo costs more, but if you want to shoot it for cheap, you can genuinely reload and handload adequate quality .300BLK for 15c a round or less, hell, one guy on here shoots it for SEVEN fucking cents per cartridge through sheer determination.
And once the gravy train has rolled for long enough, Tula or Wolf are bound to load some modestly priced steelcase .300BLK
I would be surprised if in 10 years you can't buy this ammo close to as cheap as you can .223

Standard .300cuckout vs 7.62x39 are identical in velocity and energy transfer
Subsonic .300cuckout vs dot fuddyphive ayyceepea are only different by 100 on velocity and energy
So a "modern" caliber that competes with a 70yr old wwII and 100 pistol caliber is just sad. Anyways the slavs looked into subsonic rifle calibers and made the 9mmx39 instead of gimping a 7.62x39 and pretending it's the greatest caliber ever
Go play battlefield 4 or something goddamn
why not just use a subsonic 308?

I don't think it's a fad, if that what 'meme caliber' means.
Two reasons: I actually know multiple people with guns in this caliber, as compared to none with 6.8 SPC or 6.5 Grendel. Also, it did make it into 'popular rifle calibers' on ammoseek, so I assume demand is there.
Time alone will tell if it stays as popular as it is now.
>>29557085
It'll becoming increasingly popular as the retardation around suppressors subsides. You can go from supersonic to suppressible by just changing ammo.without a significant drop in energy
>>29557085
and i know multiple people with 6.8 and .458 yet nobody with .300
anectodal experience is useless
>>29557294
If someone were trying to determine rough estimates of ammo sales by caliber, where would they look?

>>29554311
>That's exactly what 300blk is
>>29557335
You'd think the industry would compile anonymous sales statistics for gun manufacters and dealers. It would certainly put to rest the popularity of certain calibers.
But the fact that .30-06 didn't make the top 10 somewhat pleases me, just to spite all the old men who keep swearing it was the pinnacle of caliber design.

>meme round

No.
>>29558194
Slightly shorter casing.
But yes.
Although if you want to be autistic about it, it's just .300 whisper, which is based on .222 Remington, which is what 5.56x45 is based on.
As the owner of a 8.5" 300blk upper, it's been a novelty gun for me. Until wolf starts cranking out steel case 40cpr subsonic, it'll stay that way. I reload but only for long range stuff.
>>29558194
> pretty much this
I take Lake City 5.56 brass, cut it down, size it, and put 125gr .308 bullets on top. The powder used it a little faster burning than what's used for 5.56.
How long until .308 gets a .450 blackout?
Wouldn't want to leave AR10's out of the party.
>>29558342
I think anon here just came up with modern .45 gov
>>29554311
>>29557294

>>29558342

>>29548386
Maybe not that major, but the RCMP and several other Canadian police forces are buying rifles in 300 BLK.
300 blackout, subsonic, great for a silencer
>>29558342
Now that would be a meme cartridge. Expensive round AND expensive gun.
>>29559201
>Expensive round
only slightly more than 308
>expensive gun
Is 100 dollarydoos instead of 70 for an 80% really that big of a deal?
>>29559282
You under the impression that the vast majority of /k/ users wouldn't need to buy the jig and associated tools to complete the lower? Unless you're going to multi-task the items or route multiple lowers, it's just as expensive to go for the 80%.
And, no, a massive .45 caliber slug big enough to justify the big AR frame isn't going to be as cheap as the readily available .308 bullets and that's not considering what a factory load for this hypothetical cartridge would cost.
>>29558342
Ehhh. You've have to blow out the cartridge walls until there is almost no taper, which complicates headspace, since .308 headspaces from the shoulder.
And I'm pretty sure you'd end up with the same performance as .444 Marlin.
>>29558194
Yes, you can even convert .223 brass on your own.
It uses conventional .308 projectiles so it's very simply and affordable to get your reloading supplies.
>>29558342
Are you gonna travel back in time and fight in the civil war?
There's already the .458 Socom, which is practically a .45-70Gov't for autoloaders, unless you're looking to crank that shit up even more like a .45-90 loaded sick hot, and I'm wondering if you're gonna fight demon-posessed wild hogs.
>>29558494

>>29554266
>. Anyways the slavs looked into subsonic rifle calibers and made the 9mmx39 instead of gimping a 7.62x39 and pretending it's the greatest caliber ever
Soviets used subsonic 7.62 for 25 years and were pretty happy with it until body armor happened. Also it should be noted that body armor 9mmx39 supposed to defeat is known by West as CRISAT and doesn't exist anymore.
>>29560063
>You just invented the .44AMP
Fuck. No wonder the idea was giving me a boner. The only difference is that .44 isn't available in heavy, long bullets. .458 might be pushing the size a bit too far. Oh well. I guess .416 is good too.

>>29559921
>isn't going to be as cheap as the readily available .308 bullets
Didn't look into that did. .450 professional and .450 buttmaster were made for pistol bullets which run about the same on the low end as .308 bullets.
Cases are a different story, but that's not what you said
>>29560956
Nothing is new under the sun in the cartridge world at this point. Of course there was that magic powder some company shilled that was claimed to give the same pressures and velocities as a .223 in a straight wall but I'm guessing there was either stability or pressure issues that killed it.
>>29550013
> hunting deer with subsonic .223
I sure hope nobody does this.
>>29561139
An atlatl would be more capable of a clean kill.
>>29561110
Global enhanced propellant.
Either lobbying, cost or production issues or the stuff you mentioned. If it worked that well then it would be a crazy world. Mail men would have to wear xsapis and kel-tec would be cranking out double stack .25automag pocket guns all day
>>29561139
You could do a lot worse than a 77gr.
Also depends on ones definition of hunting. Chilling in a stand in front of a feeder isn't much better than spotlighting with a .22
>>29561155
I've got nothing against spear chuckers.
>>29548343
I suspect given it's popularity in the commercial market that it will stick around. The wide range of projectiles makes it useful for handloaders and fills a solid niche if you want a intermediate "do all" round. As suppressors grow in popularity the subsonic loads will continue to be popularized.
The biggest kicker in it's adoption is the fact that it works with essentially anything that can be chambered in 5.56 and more specifically the AR. For the price of an upper you can get into the .300 game. You get to use the same mags and other gear, you can stick with your lower with your fancy trigger or stock, you don't have to go through another FFL transfer if you already have an AR lower etc. The smartest thing about it is the low barrier to entry.
>>29553212
There is not reason they couldn't adopt 7.62x39, there is no reason to if you can adopt a round that works with all of your mags, on the same rifle platform you've already been using, with pretty much no re-training required. If NATO adopts .300 African American Out in any capacity it's not because it offers a gigantic advantage over 7.62x39, it would be because it offers similar performance with far fewer of the logistics cost for most of the members.
>>29561350
The logistics are the massive advantage, but we all know you mean ballistics
>>29557846
What kinda shit store doesn't carry 458 bullets for reloading
>>29561430
I'm trying to figure out what kind of store carries .308 bullets but not .458. I can imagine a store that only carries loaded ammo. That's not uncommon.
>>29561430
>>29561466
The kinda shit store that I have to buy bullets from. The guy carries various rounds from .177 up to .451FMJ and .452(LRN/Plated). He even stocks kilo-count boxes of .451, but nothing in larger calibers.
I can drive 80mi to Cabelas and MAYBE they'll have them, but I'm not about to drive 160mi to find out that they don't (or they're a $1/pc)
>>29548343
If we reduce .300 Blackout to .280 Blackout, will it help compensate for higher velocities and less drop distance
>>29562529
At supersonic speed, you would get a flatter trajectory, but you'd get less energy at subsonic speed.
>>29561193
I don't think is was lobbying would have killed it, the amount of applications and the insane money that could have been gained by other companies copying the formulation and tweaking it just enough to avoid patent infringement would have made it too profitable to simply ignore.
Might have been costs but I doubt that too given defensive ammo is insanely expensive and there are plenty that would have paid gucci money to carry a 9mm super magnum.
>>29562444
Let me guess, Hawaii or Alaska.
Kind of. It's an interesting round, but very similar to 7.62x39. Unfortunately my state bans SBRs and suppressors, so it's pretty useless to me.
It's not a wonder round that does everything great. It's a fairly niche round that does a couple things very well.
>>29563070
Which cuck state are you in?
>>29561193
>>29562839
How would you reliably headspace on a rimless, straightwall cartridge?
>>29562642
You realize that comparing .300BO and .280BO energy/distance makes this irrelevant, right?
>>29563142
Case mouth, like every other rimless straight wall cartridge.

To summarize,
>300blk works best as a subsonic supressed round
>people load 300blk with expensive bullets made for high precision, high chamber pressure, high velocity
>this makes the round expensive
>subsonic blk only deals with handgun-level pressures and velocity
>load a .30 pistol bullet on a 300blk case
Now its much less expensive
>>29563153
That's not much of a positive matching surface for reliably chambering the round. Other than .30 carbine, I don't know of any somewhat recent modern rifle rounds that do this.
Maybe there is a reason?
>>29563274
>rifle round
What about all of those pistol rounds?
>>29563304
I haven't spent much time reloading yet, but I'm going to guess the powder charges, and thus the effects of an improperly headspaced cartridge, are going to be much, much larger on a rifle bullet.
>>29563340
Firearms are generally designed to not fire if the headspacing isn't right and the concept of a non necked .223 doesn't entail making it heeled.
>>29548343
Yes 300 blackout is a meme by definition. Totally. im not being sarcastic.
>>29563388
> Firearms are generally designed to not fire if the headspacing
Unless I'm mistaken, AR15's will fire on excessive headcasing. I thought this was the cause of split bolt carriers.
> Heeled
I wouldn't think this would work anyway. Without a case lip or a rim, what's positive surface is left to headspace on in the chamber?
>>29563537
Uh, too much headspace doesn't usually do much other than make the accuracy worse or fail to fire. Maybe the case will break in the chamber.

It was a well designed roleplay post that was then printed and photocopied and re-uploaded.
But because google, all the showed up in search results was the photocopied post.
But the underlying premise is right. Straightwall 5.56 is superior to 5.56 in terms of weight and capacity.
With the right propellant, you probably could get 90% of the velocity.

>300blk works best as a subsonic supressed round
Compared to it's competition yes. But it's *best at being good in short barrels while also being easily suppressed. Being quiet wasn't the goal. 6.8spc was a better supper, but suppresses like shit.
All standard parts
Good versatility
Cheapest option
Thats why it's the best

1:10s stabilize plenty of heavy subsonics, especially the big fat round noses.
And big fat flat based round nose bullets are more accurate than bthps anyway at subsonic velocities.

Why not just bulk buy blemished lots then?

I would rather wait for a home brass machine.

Outside of forming brass sheet with a hydraulic press I don't see that happening. Though with some electrical know how and a lot of time money for dies one could hook up several cheap presses in series to automatically form brass

Because it has zero effect on me. That being said .451-452 is always going to be cheaper due to volume. Even when the good deals come along.
