Round of the Future

Pros:
>best self defense round
>knockdown power
>not designed to wound like 5.56
>easily supressed/subsonic
>hunts large game and nogs
>easily converts from 5.56
>better in short barrel
Cons:
>none, unless you're in a desert shooting at towelheads 5 miles away which no one ever does nor would they hit anyway under any measurable level of stress or hurry

Why haven't you built a 300 blackout AR? I truly believe this is the round of the future.

It's great for SBR and AR pistols, anything less than 10.5" barrels, 300AAC is a more affective choice.

It has a long way to go still. Might stand a chance.

As a person that owns and shoots multiple 300blk firearms, it is not the perfect round. It is a mediocre jack-of-all-trades round that is fun but not the future. Cool round, has it's uses, but it is not a perfect swiss army round.

My foreskin is intact thanks
Only reason I'd even want .300blk is if I felt particularly inclined to run a can. 6.5 Creedmoor is more appealing to me in almost every aspect

I assume the save a ton of tooling and money by using 5.56 cases, but it's a damn shame.

Rounds of the "Future" will be focused on armor penetration. This is something the 300BO is very, very poor at. The 300BO won't advance much beyond its niche of short rifles running subsonics.

.300 blackout: when you absolutely, positively need handgun performance from your rifle. It's only interesting as a way to run subsonic ammo out of a suppressed AR-15. That's it. If you're doing that, then you can swap out some other kinds of rounds to make up for the general shittiness of ammo designed primarily to be quiet.

Real pros:
>subsonic
>don't have to only load subsonic
>better in a short barrel than 5.56

Real cons:
>Will not penetrate armor like 5.56 will.
>Will overpenetrate walls and kill the kids and neighbors in a home-defense scenario.
>Is not flat-shooting and accurate at long ranges.
>Need to carry multiple flavors of ammo, reducing your effective ammo supply and the relevance of your optics, if you want to take advantage of the only reason to use it, and also want it to not be completely shit at other things.
>Is still shitty and underpowered for hunting.
>Ammo is heavier, so you can't carry as much of it.
>Costs more, is more scarce, and will never become anywhere near as popular as 5.56.
>Not as good in short barrels as actual pistol ammunition.
>Can't share ammunition and magazines with your pistols.
>Doesn't benefit from long barrels like actual rifle ammunition.

Bottom line: fills a very small niche for people who are too attached to their AR-15 lower receiver to switch to a pistol-caliber carbine when they want to shoot handgun-tier ammunition.

Homosexual

This. I fell for the 300 blackout meme and regret it

You make valid points, although most of your criticism comes from the use of subsonic.
I'm not OP, but my argument for the use of .300blk is based around the SBR/AR pistol concept. You can push supers out of a 7.5"/9.0" barrel at sufficient velocities to cause intermediate rifle levels of damage with a weapon the size of an MP5.
Adding a can to a barrel that length makes a package that is still the size of a 5.56 carbine without a can, and there are many benefits to that.
So rant all you want about subsonic being less lethal, but the reality is that anything subsonic outside of 300gr-500gr bullet weights is handgun tier out of any caliber, and is not a criticism of 300blk specifically because most of the ammo available is supersonic.
Supersonic is not underpowered for hunting.
Supersonic has sufficient accuracy and drop off. There is a video of Haley shooting a target at 750m with a red dot on the tubes.
The over-penetration argument has validity, but then so does handgun ammunition.
In summary, 300blk in a supersonic load allows you to cut your barrel length almost in half while retaining similar levels of energy compared to 5.56 and allows you to have a handier suppressed platform as well.

>>knockdown power
What the fuck does that even mean?

how can it be the round of the future if it's already here

It's less than half that price if you roll your own. Plus you get the option to brew up crazy shit 100gr at ~2600 fps.

>most of your criticism comes from the use of subsonic
Less than half of my points relate to subsonic.

>Supersonic is not underpowered for hunting.
Sure it is. You're like one of those guys who goes around saying, "Yeah, .223 is great for hunting." It's light. It's shitty. Not enough speed at a good mass, or not enough mass at a good speed. Less than 30-30, less than .243 Win, and those are low-end deer rifles. Does not reach the threshold of producing reliable stops without excellent shot placement. So either you shoot at bow range or you end up wounding deer, like hunting with handgun ammo.

>300blk in a supersonic load allows you to cut your barrel length almost in half while retaining similar levels of energy compared to 5.56
Wowow... almost as good as picking some spicy handgun ammo, like .45 Super, which you can carry a backup pistol for that takes the same ammo and magazines.

Really? Supersonic 300 BLK is "almost as good as picking some spicy handgun ammo, like .45 Super"?

So by "almost as good" you mean produces somewhere around half the energy of supersonic 300 BLK. You are either a fucking moron, a troll, or a noguns summer fag.

This thread is bad and you should feel bad.

Just drop 5.56 entirely. The reverse can't happen as 5.56 will not chamber in a 300 blackout gun.

lol, okay enjoy juggling your different barrels and bolts and cartridges while I shoot you in the back of the head with my handgun that does the same thing as your 'rifle'

There is literally no reason ever to run 5.56 in an AR with a barrel under 10.5". 300 BLK is the superior choice for SBRs.

What's hilarious is how you think 9mm is somehow better than 300BLK when ran in say, an 8" barrel. at that short of barrel length the only way to really measure performance is how much energy is being delivered to the target, and 9mm gets shit on completely in that regard.

There are several states that doesn't allow .223 to be used as a hunting round. It would work just fine but some stupid old laws that needs to be looked over again to make it legal.

When the rebuttal is so brutal the only thing they have left is half hearted attempts at trolling.

Did you ever see the gif of the gun store shooting in Georgia where the nog literally gets knocked over by a .45?
Fuck off. Knockdown power is actually a thing, believe it or not. That energy doesn't just vanish.

>There is literally no reason ever to run 5.56 in an AR with a barrel under 10.5". 300 BLK is the superior choice for SBRs.
There is literally no reason ever to run a cartridge that's not compatible with your backup pistol in an SBR with a barrel under 10.5".

>What's hilarious is how you think 9mm is somehow better
Did I say 9mm anywhere? No, not once. I said "pistol ammunition". Sure, 9mm is one of those options, but there are a lot of options for paired pistol-caliber carbines and pistols.

>how much energy is being delivered to the target, and 9mm gets shit on completely in that regard.
No, 9mm out of a carbine barrel delivers pretty much the same energy as .300 subsonic (i.e. the only sensible reason to ever consider .300 BLK). Matching it subsonically with 9mm is a bit tricky, but if you want a bullet of the same mass and speed for a compact suppressed carbine, you can use .45 ACP or .40 S&W. If you want to match its supersonic muzzle energy, .45 Super comes pretty close.

If you insist on having an SBR that's not a PCC, and you don't care about having subsonic ammo, and .300 BLK is good enough, then odds are 5.56 is good enough too. Yes, 5.56 loses a lot of performance in a short barrel, but it's still going to pop right through soft body armor and hit harder than .357 Magnum. People don't pick 5.56 as the most optimized performance round, it's what people default to when it's good enough. The ammunition is cheap and common, and you probably have it for other reasons. .300 BLK is only going to be marginally better. Why go with some weirdo round for that?

There's a whole world of other options than an AR-15 with .300 BLK. For instance, if you want something like your AR-15 but shorter and handier, you could get a 5.56 bullpup. If you're not happy with 5.56 terminal effect, the tiny step up .300 BLK represents is unlikely to satisfy you, when there are options like .50 Beowulf or a proper 308 battle rifle or a 12-gauge shotgun.

>Projectiles choices

Still a proprietary round owned by Alexander Arms that requires licensing agreements to load or build guns chambered in it. You're making an objectively shitty choice by choosing it over 458 SOCOM for big bore application just due to this alone, but it gets better.
>better .458 SOCOM ballistics
Did I say it did? I said if you wanted brick ballistics it was the better choice than 50 Beowulf for above reasons and has better bullet selection to boot due to using the chad .458 cal projectiles instead of virgin .500 cal.

>That's a 1917 parker SxS BTW

Wow, that's some impressive research there. You went to Wikipedia and grabbed the examples without even noticing that you're comparing .45 Super out of a 5-inch barrel to .300 BLK out of a 16-inch barrel.

At around 10-12" inches, you can find .45 Super ammo to approximately match the highest .300 BLK muzzle energies.

So basically if somebody shoots me with .300blk and I happen to notice, it might sting a little bit? Leave a little red mark?

>.300 BLK out of a 16-inch barrel
Who in their right mind would run .300 BLK out of a 16" barrel? Most people run it in 8-10" barrels because you pretty much have gotten everything our of 300blk by 8", the 10" barrels are pretty much to help with cycling suppressors to give the gases more dwell time. If you want to compare apples to apples you'd use 8" test barrels for both rounds.

>At around 10-12" inches, you can find .45 Super ammo to approximately match the highest .300 BLK muzzle energies.
*Citation needed

That's a rather interesting claim, being that 45 Super is going to be loaded with pistol powder, which is designed to burn completely in ~5" of barrel to maximize it's power out of a pistol. I'm sure you'll get some extra oomph out of it by adding barrel length, but I'm pretty skeptical of finding an extra ~700 ft.lbs without resorting to some pretty exotic loading if we are talking about standard 8" or so 300 BLK barrel length; and if we are going that direction, you could do the same sort of nonsense with 300 BLK and push it even higher. Then there's also the fact that .45 cal pistol rounds have shit ballistics compared to .308 cal rounds, so 300 BLK would be a superior choice because of terminal ballistics. That's the beauty of 300 BLK, it gives you reasonably powered subsonics while giving you x39 tier supers all in one platform, it's not the best at anything, but gives you lots of options in a small package.

Not him, but a quick google for .45 Super out of a carbine found ballisticsbytheinch.com/45super.html

Best result was an 18" barrel, Underwood 185gr @ 1600fps

She's cute.

>better brick ballistics.
Your reading comprehension can't seriously be this bad. Nowhere have I stated 458 SOCOM was more powerful or has better ballistics, simply that it was a better choice due to A) being non-proprietary/better supported and B) having better bullet selection if you're inclined to reload.
>MEPS rejects LARPing in flecktarn

>"458 SOCOM for brick ballistics"
> "I said if you wanted brick ballistics it was the better choice than 50 Beowulf"

You're a fucking idiot and anything you post has zero value.

SMGs and PCCs are being phased out in favor of .300aac SBRs in most divisions of anything that use the former. Aka not a dead round. Here's something to think about. The best ammo for 5.7 is damm near exclusively sold to the SS yet 5.7 is still relevant to the public (I personally am not a fan but who cares?) And that's an incredibly niche market. 300 blackout has far more diversity in terms of application, types, and a much broader range of firearms that actually use the round. Moral of the story.. .300 blackout is old news when newer rounds come out, but the same happens to any other round a few years later. But also there's a reason why specifically for the sake of the 300 you can buy ammo for $0.35 vs. 3 years ago where it was $0.50+

>Actually, you did. A couple times.
Are you seriously this dense? I was referring to it being the superior choice BECAUSE it is non-proprietary and has more projectile choices. If your going to quote at least be honest about it and don't quote-mine. I'll break it down for you because you seem to be a intellectually dishonest blithering idiot.

>Not using the better supported 458 SOCOM for brick ballistics
key here being the phrase "better supported", it's chiefly marked by a lack of discussion on power or ballistics.

>Still a proprietary round owned by Alexander Arms that requires licensing agreements to load or build guns chambered in it. You're making an objectively shitty choice by choosing it over 458 SOCOM for big bore application just due to this alone, but it gets better.
and
>I said if you wanted brick ballistics it (458 SOCOM) was the better choice than 50 Beowulf for above reasons and has better bullet selection to boot
Yet once again, claiming 458 SOCOM is superior due to being non-proprietary and having better projectile selection. Nothing here about power or ballistics, no siree bob.

Notice how nowhere in that discussion did I say "more powerful" or "has better ballistics"? I was saying they both have .45-70ish brick ballistics, but one is a superior choice due to not being hamstrung by Alexander Arms and having a better projectile selection.

Holy shit, do you even into reading comprehension user?

There is literally no reason to ever run an AR that has a shorter than 14.5 inch barrel

>Who in their right mind would run .300 BLK out of a 16" barrel?
Ammunition manufacturers. Who in their right mind would run supersonic .300 BLK?

>I'm pretty skeptical of finding an extra ~700 ft.lbs
You don't get 1400 ft-lbs out of .300 BLK unless you go to a full-length rifle barrel. More realistic performance maxes out around 1100 or 1200 ft-lbs out of a 10.5" barrel. The hottest off-the-shelf .45 Super gets up near 1000 ft-lbs around a 10" barrel:
ballisticsbytheinch.com/45super.html

>That's the beauty of 300 BLK, it gives you reasonably powered subsonics while giving you x39 tier supers all in one platform
Hah! No, it is glorified pistol ammunition, an experiment in converting the M4 into a silenced submachinegun while changing as little as possible about how it works and feels and imposing the minimum logistic burden. It uses pistol powder so you can shorten the barrel to gain length for a suppressor so it's as handy as a regular M4.

Don't kid yourself that it can match 7.62x39. It maxes out at about 2/3 of the muzzle energy. As soon as you stop caring about silence, it's a significant downgrade even from 5.56. It has pretty much exactly the case capacity of .45 ACP (which is why it takes little tweaking to make it do the same things out of the same length of barrel).

It is literally a way of downgrading to pistol ammunition. .45 ACP was their performance target. Special Ops wanted to be able to switch their doorkickers over to silenced submachineguns and back with no retraining or other equipment changes (like vests with different magazine pockets).

All of this shit with trying to shoehorn it into other applications is pure silliness.

You didn't do very well in your logic & reason courses in school did you?

How does the buffer work? Does it go into he grip? Nogunz here

>Who in their right mind would run supersonic .300 BLK?
Plenty of people, Its actually the cheaper option for both buying ammo and reloading, the heavy .30 cal projectiles are expensive.

>More realistic performance maxes out around 1100 or 1200 ft-lbs out of a 10.5" barrel
>The hottest off-the-shelf .45 Super gets up near 1000 ft-lbs around a 10" barrel
So what you're saying is 300 BLK has 10-20% more energy at muzzle in same platform out of the same barrel length while having better terminal ballistics at any distance due to better projectile design. Seems pretty significant to me

>Don't kid yourself that it can match 7.62x39
You might want to go check out wikipedia and the white papers it links, that is actually one of the stated claims. 125gr 300blk and 123gr x39 have very similar performance, with x39 having ~12% more energy at muzzle (Underwoods numbers), but 300 BLK retaining more energy at longer ranges.

>It is literally a way of downgrading to pistol ammunition. .45 ACP was their performance target.
Yes, for subs designed for use with suppressors, not supers

>Special Ops wanted to be able to switch their doorkickers over to silenced submachineguns and back with no retraining or other equipment changes
Yes, It's a jack of all trades round that does several things reasonably well, but only one thing great (running suppressed in SBRs).

I hope you die

I just want to load sabots in my 300blk
