Is .300 Blackout the greatest meme cartridge of all time? I know that 6.8 was supposed to be, but that never caught on.
>top meme cartridge
>not .45 GAP
>not .460 Rowland
>not .950 JDJ
>not .22 Hornet
>not the many number of big bore revolver cartridges that all do the same thing
He's gonna castrate me for posting this but this is my buddy's .300blk and I'm pretty damn jealous. I've invited him to my place to shoot hogs and should have pics and webm's as soon as we hook up the FLIR to his rifle.
10millimemer has gained some traction in the past few years.
.357 sig is up there though. High pressure pistol calibers are all memes barring the .40, it's just shit.
>.357sig, turning any handgun into a Tokarev, overpenetration and all
Personally I want to see someone replicate a .357mag round ballistics without the loss of performance from a shorter barrel
+1 but I'll add that unless you're going to reload for it then don't bother with memeout.
I have an SBR, suppressor, and roll my own ammo. Under those circumstances it's fun as hell to shoot.
>I'd take an SBR AK in 300BLK if I could find one.
They've had those for awhile.
It's called 7.62x39
Only if you plan to never want to shoot subsonic suppressed.
Out to 300m, 300BLK is objectively the best all around cartridge for the AR-15 for sub and supersonic, since it can do both very well to that range.
For me, this is absolutely fine since the AR-15 in my conception is a 300m rifle, 500m extreme long range.
/k/ just hates on 300BLK because they're poorfag retards and have never learned how to use a mil scope and perform basic ballistic calculations.
.300blk is basically the same shit as 7.62x39
Except you can actually find subsonic loads for it, and they're cheaper, plus it has slightly better ballistics with super sonic loads, and the real reason is because x39 is fucking garbage out of an AR and the AR is vastly objectively superior to the AK.
I don't hate 5.56, I think it's fine. I just think 300BLK is objectively better for the ranges that the AR-15 is designed to engage at, and I like the AR because it's the best carbine ever designed that was lightyears ahead of it's time and has yet to be challenged overall, merely slightly improved on.
Oh boy here we go...
/k/'s constant retardation in thinking that 300BLK is a subsonic load, period.
I fucking hate faggots like you, you've ruined this board. You truly have.
.30-30 is a good cartridge ballistically though. The fact that .300blk isn't rimmed, can be fired out of an AR, uses standard AR magazines, only need 9" of barrel to fully burn its powder, and can be loaded subsonic for near silent (for a gun) use with a suppressor is basically the cat's pajamas.
It's a great round that has caught on. With the surge in suppressor ownership, it has gotten even more popular. You don't need a suppressor to enjoy the round though. Supersonic .300blk is pretty fantastic for things like hunting, and the cost has come down a lot in recent time. If you roll your own, it's even cheaper.
That's basically what 10mm does in a slightly fatter bullet. And before someone pops up with the "10mm is equal to .41 Magnum" myth, those ballistics are from 10mm Magnum, which the Automag MkIV was chambered for.
.460 Rowland equals lower end .44 Magnum performance. At the upper end, .44 Magnum walks all over it. Not knocking .460. You can get .44 Mag performance with a double stack auto loader with it. But it can't do what upper end .44 Mag can do.
> A Blackout shooter in their natural state: looking for brass
just looking at underwood ammo, 460 rowland is 1000~ftlbs of energu and the hottest 44mag is 1100-1200ftlbs of energy.
fwiw your average box at of non boutique ammo of 44mag is 800~ftlbs of energy.
>what is resizing 5.56 brass
h e l l o
n o g u n s !
True, but PPU has a 1150 Ft lb 240 grain load in an off the shelf 50 round box. They also have a 300 grain load at 1000 ft lbs. both go for about $30
And I notice you left out Underwood's big 340 grain .44 Magnum +P+ load that generates 1533 ft lbs of muzzle energy.
Granted, you want to keep that particular load away from anything but a Ruger single action, Redhawk, Super Redhawk, Dan Wesson or Colt Anaconda, but that's a whole nother level.
I was actually pretty surprised to find out it has dramatically more energy than 5.56 at any range while keeping an acceptable trajectory thanks to the ballistic coefficient of .308 bullets.
It's pretty pointless unless you own an ar or can buy suppressors.
Thanks to Canukistan's gun laws I think I'll buy a 7.62 bolt cz.
It would be a nice round if I could buy a fucking ar and a suppressor.
I gotta say .50GI.
Loads of of other calibers have limited niche utility, but at least there is something legitimate.
But 50GI has nothing else going for it besides you can say it's
You specifically want 5.56 bolt head and mag chamberings?
6x45, 6 T/CU, 6.8x45 UCC. Any number of other wildcats sharing the base .223 rem case. 300BLKs achilles heel is its lack of case capacity after being cut down.
> Not building a .300 blackout pistol with the Shockwave Blade "stabilizing brace". Pic related.
> Not enjoying standard AR component compatibility, including bolts and magazines.
> Not getting more energy out of a 9" barrel than a 16" .223.
> Not having the perfect platform for rifle caliber suppression.
The only two complaints that anyone has from the .300 is ranged shooting and cost of ammo. I don't deny either of those but offer the following rebuttals:
- Yes it's true that .300 dies off quick after 200 yards or so. I'd say that this is a stupid argument in that 90% of the people bitching about this have never shot their 5.56 AR past 100.
- Yes, ammo is more expensive than 5.56/.223 and there is no steel cased offering at this time. That said, more ammo manufacturers are hopping on board and you can get 20rds of quality,reloadable brass cased FMJ for $.60 cents per round at Cabelas every once in a while. I've also seen remanufactured at that price or slightly cheaper pretty regularly.
If I could only have one round in the AR-15 platform then I'd probably go 5.56/.223. There is no reason to shit on the .300 as an alternate/secondary AR-15 selection, though.
Eh, there are advantages to going with an AR pistol vs. an SBR. No doubt the SBR is "cooler" but avoiding the $200 tax stamp and the pain in the ass of traveling out of your home state with an SBR makes a pistol more attractive. Some states also don't allow for SBRs or have SBR length restrictions (yes, MD restricts SBRs OAL with their new retard laws - currently being fought in court).
And let's be honest, a pistol with the sig brace or shockwave blade make it function nearly the same as an SBR, especially if you arent shooting in public.
this is mine
SBRed and my Silencerco Omega is on the way.
Buying a Dillon 650 with the 550 case trimmer to make brass from 556. already been stocking up on components, have everything but power
300blk is fucking fun as fuck, 10x the fun of a regular AR
anyone who disagrees as never experienced the joy of shooting a SBRed 300blk suppressed
also, 300blk is only a meme cuz 98% of people are sour grapes, poorfags
Because the overwhelming majority of /k/ are 25 and under NEET poorfags still living with their parents, with over half of them in some communist shithole like NJ or Cali.
Because of this they have massive hardons for slavshit, since those are cheaper to feed and frequently cheaper to procure.
In what way is it a meme? No, being popular does not make it a meme.
>fatter cartridge=more recoil, less mag capacity
>nearly the same velocity but with a lighter bullet (100 vs 125 @ 2650 vs 2400)
>reloading components are unobtainium (literally nobody makes -just- the bullet for sale)
>factory 6.8 plinkers cost more than factory .300blk hunting/defense ammo
6.8 was supposed to be a "long range" round. Except the light .277 bullet has a ballistic coefficient of a shuttlecock and actually drops and drifts more, faster, than 5.56.
Eh. It's top-third of .44mag loads. Yes, there's some rape-everything .44mag loads out there that specifically state "Ruger/rifle only" that exceed it, but they're incredibly expensive and still hard on guns. People keep forgetting that .44mag is very versatile, and has loads ranging from literal powderpuff bullseye loads to bear-rapers.
Or, if you truly want a fuck-everything pistol caliber, you always have .400 CorBon. Or if you own a Deagle, .440 Corbon. .400 CorBon has more ME than .454cas and .440 Corbon has about the same ME as factory .460smith. But they're bottleneck, wildcat, pistol rounds.
As much as I'm a fan of oddball and wildcat chamberings, 6 T/CU doesn't fit in mags. It's too long. Also, the 45* shoulder means it doesn't feed. Period. Not it doesn't feed ~well~, it literally will not feed.
Some of my other favorites are 6.5MPC, .25-45 Sharps, and if you only care about ME and/or a laser-flat trajectory .17-223.
>higher MV from a shorter barrel
>higher BC bullets
>lower recoil because literally half the powder to get similar-weight bullets to the same speed
In what way other than cost is it worse?
It's an underperformer that's artificially expensive because it's got Bill Alexander's fairyfarting lawyers collecting royalties and only licensing it to a select few manufacturers.
There's a reason .264LBC is the same. Just barely different enough chamber dimensions to skirt lawsuits (not that AA didn't try, they just got BTFO in court), shoots 6.5gren ammo more accurately and reliably because AA can't design a chamber to save their asses.
Have you never seen ChuckHawks?
You can calculate recoil impulse. Scientifically. Through same-weight rifles, .300blk 125gr loads recoil about 20% less than 7.62x39 123gr bullets, while going about 100fps faster.
Basically, it really ought to be going faster given the powder volume. An actual, AA-spec chamber is set up for a fairly low pressure round, and this causes it to be fairly low velocity for what it is.
6.5MPC, which is .223-based, achieves higher velocities with marginally-lighter bullets (107 SMK vs. 123 Amax) while recoiling significantly less and being an overall stronger gun due to using a 5.56 bolt/bolt head.
Yes, it is hands-down the best extreme-range caliber capable of being crammed in an AR, but that is SOLELY due to the high-BC bullets that were custom-designed for it (123 Amax). However, if you were to have a bolty or single-shot and thus got rid of the maglength constraints, similar brass-length rounds would do better (specifically 6.5MPC and 6mm PPC).
Not fully. Having never really gotten too deeply into the hows and whys, I'm not sure if it's a brass issue (it's a blown out x39 case with a humongous flash hole) or bolt-head wall thickness or what. Possibly a combination.
The .264LBC is generally a tighter chamber, and the big thing is it's got a parallel throat and leade. They tend to be much more accurate, not that a 6.5gren chamber isn't capable of great accuracy.
It's a fun gun, and is definitely the best LR caliber that fits in an AR, but it should've been better.
IF you can reload, there are some interesting 6mm wildcats based on the Grendel and 6.8. 6/6.8 is a HELL of a screamer with the mid-heavy match bullets. Not sure what its max supersonic range is, but it's fast and has a high BC so it shouldn't drift as bad as the Grendel. I've always had a harder time doping wind than dialing or estimating holdover.
As far as I know SSK Industries is the only one producing ready-to-go uppers in it, and because it's SSK they're expensive. Black Hole might be able to do a barrel for you though.
Comparing a 20 cent a round cartridge to a 50 cent to $1 a round cartridge.
If I was going to pay that much I can get a 7.62 with the same performance, I could also get fucking MK262 5.56 and drop a man dead at 600 yards.
Fucking retard 300 blackout fags can only win when comparing their expensive loading to shitty com block animal brands and surplus, its pathetic.
7.62 can be found cheap as fuck and all over the planet as its used in the most issued rifle in the world, If I want better ballistics out of it I can get that too, there's plenty of devastating loading out there for 7.62.
300 shitout getting btfo by 5.56 and 7.62 yet again.
>Comparing a 20 cent a round cartridge to a 50 cent to $1 a round cartridge
Whoa whoa whoa anon, whoa. That's a spicy opinion you got there.
.300blk is good because you can reload it for peanuts, even with shot 5.56 brass, the bullets themselves are cheap and overall you don't gotta fuck with your AR much to get it going. Subsonic .300blk is also a better suppressed round than (I can't remember the last time I saw this) subsonic suppressed 7.62x39.
.300blk is definitely more worthwhile to go for if you already have a 5.56 AR. You can even use 300blk in your old STANAG mags, which furthers the appeal for AR15 owners.
Now you just want a .30 cal intermediate rifle
>AKs all days
>7.62 will do
Not hating. But howboutdatmudtestdoe.
>this round is objectively better
>WAAAH ITS EXPENSIVE I CAN'T AFFORD IT WAAAH $500 AK GOOD ENUF WAAAH IM A POORFAG WAAAH
By that metric, you should only ever use .22lr. I'ts the cheapest, since that's apparently the only thing that ever matters.
Genuinely curious as to why you think either of those are meme?
Came about as an IPSC caliber prior to the existence of either 10mm or .40s&w because you could meet major power factor without unduly stressing your gun or dealing with rimlock. 100% obsoleted by .40smith.
Because getting .454 casull ME in a double-stack autoloader is a bad thing? It's a niche hunting/silhouette round, sure, but I don't see how it's meme.
Nah, because in the off chance that you are caught (or caught transporting) you can just point to the paperwork to show that it's approved to shoot with the brace as a pistol.
Speaking solely of the Shockwave Blade, it's literally 90% as comfortable as a stock. It's actually not even bad just putting it on your cheek. You can also get a dimpled buffer tube allowing you to really lock it in to your desired position.
I see it as 9/10's of an SBR with 1/10th of the hassle...
>Except you can actually find subsonic loads for it, and they're cheaper, plus it has slightly better ballistics with super sonic loads, and the real reason is because x39 is fucking garbage out of an AR and the AR is vastly objectively superior to the AK.
Let me translate that for you.
>Because it made more sense to make 300blk than to simply make subsonic 7.62x39.
>Because they have basically the same ballistics, despite what I say.
>Because ARs gonna AR
The last reason is the only legit reason....even though there are 7.62 ARs....
Let me translate that for you.
>it goes faster with heavier bullets
Muh 20 FPS. How do they perform ON THE RANGE? About the same.
>less recoil from shorter barrels
Cite. It goes faster with heavier bullets but recoils less? You a lie.
>Also subsonic loads are (widely) available in the US
Would have been easier for ammo manufacturers to just offer subsonic 7.62, bruv.
What's the actual working appeal of the .300 though? It's worse for target shooting and more expensive than 5.56. Differences in their terminal capabilities are all but irrelevant if it came to having to use the rifle defensively.
>intermediate .30 cal rifle
An SKS is like $300 or something. A .30-30 can be found in the same price range, maybe a little more. For the cost of the conversion you can just get a whole other gun.
>What's the actual working appeal of the .300 though?
holy shit, read the thread
300 is ridiculously practical. Especially if you want to shoot suppressed.
>It's worse for target shooting
kek, that's why I target shoot with my SBRed 300blk more than any of my other rifles
cost of 30-30 is ridiculous compared to 300blk especially if you reload
Not completely true, one needs full chamber support so you don't kaboom your old .45.
Now there are some that are certified for .45 super, like all of HK's USP line (and derivatives), and Springfield XD's and Bobergs
