.300 Memeout

.300 blackout has baller ballistics bro

I really want an ar chambered in 300 blackout. but only if I can get my hands on a suppressor.

Why does /k/ hate anything that's new and good?

>>28505146
Shut your face, you ass-belonker.

300blk is an easy way to make AR-15's fire a bretty gud .30 cal cartridge.

if you want the ultimate meme cartridge, go look at .45 GAP

>>28505124
As long as the barrel is in the target's mouth, yes.

>>28505610
Your buddy was a yard for not getting .277 wolverine.

Not to be some shitty slav loving faggot, but .300blk is basically the same shit as 7.62x39 except more expensive because it can use your precious AR mags.

like if you hate 5.56 why use an ar?

if you want a new caliber why constrain yourself to the dimensions of stanags?

>>28505670

If you're familiar with a rifle's operation and it shoots straight, why not get the samr gun in multiple calibers if that's what you want?

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.

>>28505637

.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.

>>28505670

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.

>>28507639

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.

300 blackout is the same as .30-30 ballistically

>>28506224
>overpenetration meme
>bawww it werks too gud

>>28509077
.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.

>>28509077
So is 7.62x39, but you can use .300 blackout in an AR that doesn't have retarded magazines and parts.

>>28505114

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.

>>28512011

.45 Super is identical to 10mm. It's the most underrated cartridge I can think of because anyone with a .45 pistol can get stronger springs and double their weapons power.

>>28508447
.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.

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.

>>28509077
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.

>>28505670
Well the AR15 is a great rifle. And all you need is a new barrel and gas bloc. Why get a new gun when you have a perfectly good system on hand?

>>28507577
It's cheaper than .308 now so cost isn't that big of a problem now, and it keeps going down.

>>28512534
Suppressor is the key for 300BLK being worthwhile. There are superior kinetic chamberings that fit in AR mags if that is your only concern.

>>28512605
Care to name these cartridges? Specifically any that can use standard 5.56 parts aside from the barrel?

> 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.

>>28507589
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.

>>28505114
In what way is it a meme? No, being popular does not make it a meme.

>>28505637
Except it goes faster with heavier bullets and less recoil from shorter barrels.

Also subsonic loads are (widely) available in the US, the only country that matters.

>>28507639
Except...well...
>fatter cartridge=more recoil, less mag capacity

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.

>>28508165
>does literally everything worse than .300blk
>THEY'RE EXACTLY THE SAME LALLALALALA GONNA IGNORE ALL THE BALLISTIC CHARTS AND RECOIL CHARTS LALALALA SLAVSHIT IS BEST SHIT

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.

>>28512341
uh, their 1500ft-lb load is rifle-only. They even specifically state that, and the testing data is from a 16" barrel.

That doesn't really count.

>>28505342
ass spelunker, you mean?

wtf is a belonker?

>>28512785
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.

>>28512908
>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?

>>28518868
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.

>RECOIL CHARTS

>>28519081
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.

>>28519079
>It's an underperformer

Why so? I thought it was guite potent for longer ranges, compared to a .223. Got more info?

>>28519112
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).

>>28519174
Interesting. Is that problem alleviated with .264LBC?

My only AR is in 5.56 at the moment, and I'd like to try something new with a different upper.

>>28519174

Thanks for the info, gotta look more into MPC.

>>28519198
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.

>>28519212
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.

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

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...

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.

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

>30-30

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
