Too much bullet, not enough powder.

>>33982618
Afaik its primary purpose us as a subsonic round for close quarters engagements in suppressed rifles and pretty useless outside of that purpose. Usually better to buy a widely used round unless you fit into the extremely specific niche that the 300blk is designed for.

>>33982618
the best intermediate rifle cartridge is whatever the caseless variant of the LSAT will be chambered in. This is not debatable lol QQ

>>33982618
Because 5.45x39 is the best

>>33982618
6.5 creedmore is the best

>>33982618

The ballistics are dogshit

>>33982618
It's not an intermediate rifle cartridge because it can't pierce armor, basically a glorified pistol round
More energy than 556 but ridiculous trajectory past 300 yards
Arguably the best cal to reload dueing the apocalypae but who even does that
It's optimal in 10 inch barrels, anything over is retarded
If you pay the gubmint extortion fees for stamps it makes for a good portable platform to whisper death in urban areas
Pew pew pew can change to bang bang bang due this cartridge's subsonic/supersonic versatility

>>33982618

It's not 5.56x45mm NATO

>>33982618
the reason is in your image
762x39 is cheap, plentiful, and established. the masses don't care about it being subsonic and suppressors.

maybe you need to make a thread named "why is 300 blackout not the best niche AR cartridge?"

Not using 7mm with better bc etc

The military is looking at new rounds right now because that isn't true

>>33986469
This.

5.56 has no power at that range. 7.62x39 may drop off at that range but at least it can crack a windshield.

it's 7.62x39 but worse in every way possible.

>>33982972
Looks like it'll be a long 6.5mm bullet that weighs just a few grains less than a 7.62x51 bullet.

because it's pointless. It's barely an upgrade over 5.56, considering it has its own set of tradeoffs. Maybe it's a slight optimization of the service rifle's cartridge, but is it worth rearming your entire army for?

The modern firearm has hit a wall. The next time you see a new standard issue weapon i nthe hands of infantry it will be radically different. Whether it's airburst, directed energy, or "smart" in some sort of way who knows.

So you CAN use the same bullet to reload 7.62x51, .300 nigout, and 7.62x39?

That would have to make it safe to reload into 7.62x54r AND .30-06, right?

>which bullet, between all those calibers, could be (most) safely loaded into the brass of all the others...

>>33988933
No. 7.62x39 and x54R are actually around .311

>>33988949
So, bigger?

>>33982618

I'd say it's less of an intermediate rifle cartridge and more of a spitzerized pistol cartridge.

With that in mind, it makes sense in opting to run a short barreled AR15 in 300BLK than any number of sub guns. The manual of arms remains the same, it is only a barrel difference, so logistically it fits the niche that it was designed for.

>>33988956
he .311 bullet is based on groove diameter rather than bore diameter

you can shoot a .308 bullet through a .311 barrel, but youll get shit accuracy and reduced velocity

if you shoot a .311 through a .308 bore, youll get massively increased pressures and a probable blowout of the case head or worse

anyone who shoots old mil-surp rifles knows that he has to slug his bore and use the correct diameter bullet for his handloads

anyone who shoots mil-surp rifles with mil-surp ammo is a cheap poorfag who deserves what he gets in accuracy, corrosion and terminal ballistics.

>>33988949
not always .311. they vary wildly
7.63x54 r rifles (mostly nuggets) can slug out with a groove diameter anywhere from .305 to .318

commie bloc machining is hardly reliable

>>33989069
So in a worst case scenario, one "could" reload the brass of all the rounds >>33988933 with just the .308 bullets safely (albeit with maximum performance loss for some rounds)?

>>33989094
yes.
.308 diameter bullets will fire safely in any 7.62/308/303brit firearm provided it is in good working order
you can shoot a bullet through a barrel as long as it is equal to, or smaller than the nominal bore size
better to use the right size bullet though.

It's too gay. Caseless has problems with heat management and cook off risk.

Now, telescoped ammo in polymer cases? That's a realistic, viable and significant upgrade that reduces weight and size while maintaining power.

>>33989435
>>33989442
looks like a .30 caliber bullet that has been forced through a .223 diameter bore, probably from a pressure test action, since anything else would be more likely to blow the ass out of the action than push that slug downrange

> a catastrophic failure cant kill you when it goes off right in your face in an aluminium action

If yes, isn't it fired from a test gun specifficaly designed to withstand internal pressure far above all limits?

>>33989527
>>33989290
It does seem that this is a real threat when you are simply practicing with two calibers at the same range trip.

How do you people prevent mix ups? Careful consideration before insertion is all well and good when just going at your own pace, but if you are practicing something that requires rapid fire and reloading (3gun, pretty much all the shooting sports), you can't check it all careful each reload.

Just a lot of checking and rechecking before getting to shooting I take it. Sounds anxiety inducing all the same.

>>33986520

Their energy is roughly equivalent at that range in "classic" loadings, at least read up on a subject before you spout off about it. Newer 5.56 loads outperform 7.62x39 handily, delivering 500+ ft lbs of energy at 400m.

>>33987035
Could you manage to pack a few more memes into that post?

>>33988898
I don't see the point for them unless they need to be packing a special gun along for something super sneaky.

There's no point in SF groups engaging in caliber autism. 5.56 works, ammo will be available to OPERATORS wherever they go. It sure would suck to land at some FOB somewhere only to find that the snowflake ammo you need hasn't arrived yet.

Personally I hope that .300 Blackout gets popular in the civilian market, it's great for pistols and SBRs meant for defensive/SHTF/Urban use.

I'm planning on building a pistol for it soon, I'd like to see some more variety in commercial loads.

>>33989572
if, for example, you own a .308win and a .300sav rifle, you simply keep the two calibers of cartridges and the two rifles separate.

i sort my brass after a trip to the range, and its not that hard.

i have never put a 9mm case through mu 10mm dies, nor have i ever tried to load a 38/40 with 357 dies.

a careless shooter is a careless shooter, and careless shooters invariably cause retarded shit.

>>33989572
addendum...
if you have 2 diffferent 8mm mausers, one might be a J bore (8.2 mm diameter) and one might be an S bore (7.92 mm diameter) dropping a J Bore 8.2 mm mauser cartridge through a 7.92mm S Bore mauser can fuck some shit up, and since the two cartridges are identical in all but bullet diameter, exercise caution.

TLDR: be extra careful with 8mm mauser cartridges. theres a fat one and a skinny one

>>33989497

why does this happen so often, how fucking stupid do you have to be to confuse a 5.56 with a .300 blk

>>33982618
Because 5.56 and 7.62x39 are much cheaper and more plentiful. 7.62x39 has essentially the same ballistics as .300.

.300 is just the best SBR/suppressed/thumping things inside of 200yrds intermediate cartridge for an AR pattern.

Frankly at that point id probably just get an AK in 7.62x39 for the cheap ammo unless money was no object or i reaaaaaly wanted it to stick to the AR platform.

You daft fucker. They are just looking at better rounds than the 5.56 in general. The Blackout is a god damn meme. Every single round that the military is thinking about is some kind of 6.5 or 6.8. I can't even figure out why .300 Blackout got popular? Is it because you faggots want a bigger round but for some reason want to use the same brass? What is it? It has an fucking edgemaster name and you like that?

>>33989290
This is not common to have this exact issue, I've tried it purposely with all my loadings and I usually have them fall in or stick out slightly. Not using exactly the right length bullets though.

>>33982618
It costs way too much and due to its lack of taper steel case ain't gonna happen.

no steel case + non-mil = boutique

I still choot it, but I have to buy reman because it's literally half the price of new subs.

Those numbers are a little inflated for the 5.56, and taken from Wikipedia, which lists a 20" barrel length which nobody uses or wants. As a rule, .300 blk starts with more energy, and retains it longer.

Plus, if energy is your standard, a 9" .300 blk will do better than the current 14.5" M4A1. All while having way less blast, almost no flash, maintaining a solid 300m effective range(which we adopted the 20" M16 for in the first place), having way better intermediate barrier penetration, and better terminal ballistics than the longer 14.5. Plus if you must shoot past the 300m POU that we've tailored our entire fighting style to, the bullet is good for farther if you aren't a total knuckledragger and can learn some basic holdovers, it's not hard. AK users have been doing it with dug-up AKs for a long time.

Look up the numbers for yourself, you'll see.

>>33998856

>>33998143
And in what other areas do 5.56 beat .300? Trajectory is the only thing, and that's plenty easy to 500M, and your 5.56 is a joke at that distance anyway.

>>33982972

Except that the Army will cancel the LSAT just as it's about to hit the field so that they can start a new project with slightly modified requirements.
