300 blackout is a gigantic meme.
Supersonic 300blk is just 7.62x39 for the AR, but worse.
>but it was actually made for subsonic loads out of a short barrel!!
Even if we're comparing apples to apples, subsonic 300blk is literally worse than 9mm:
https://www.youtube.com/watch?v=BnedpQ4xTIo
But 9mm isn't limited in platform like 300blk. There are a shitload of different 9mm firearms in a shitload of different packages for different needs.
>but it was actually made for longer distances!! You can change from subs to supers if you need to!!
So you can do 2 things shittily. Amazing.

It's a poor attempt to make the AR do everything. It's not even good for hunting.

Video you posted would be pretty dependent on the specific hollow points used
Subsonic 300bl will also be better at medium ranges than a 9mm because of a better ballistic coefficient
And the idea of going from the equivalent of a subsonic 9mm carbine to a 30cal rifle round with the swap of a magazine is pretty fucking dope

Yes anon we can't cheat mathematics. 300 Blackout's main problem is the bullet diameter is so low yet the sectional density is so high you are inevitably just going to ice pick a 30 caliber hole through the target with subs. 338 ARC tries to address this with insignificant advantages

I dare say if you live in a forested area or an urban area (~85% of the US population) then a PCC AR in 10mm or 45 makes far more sense than any sort of 60k PSI rifle chambering.

>just 762x39 but worse
Maybe, I dont know, but I can use 300 blackout with the same magazine and bolt, so that gives it more value in my eyes. And most people that like .300 do because it's decent at suppressing, which 762x39 fucking sucks at because its bullet weighs the same as 9mm.

Look at real world hunting performance of of good supersonic .300 blk(ex 110gr Barnes, 110gr VMAX) vs comparable 5.56 loads. Notably bigger holes from notably shorter barrel lengths. .300 blk is good, but ammo cost makes it not worth it for most people unless they reload.

Anon, it is a loading with a velocity limit that is optimized for a 16" barrel.
The same BLK sub projectile at the 9mm's (still subsonic) velocity would jump it to more than 20% higher energy.

>energy
Bullets do damage in two ways.
One, the temporary cavity. As the bullet enters the body, the shockwave creates a cavity in the tissue. For a lower speed round, this does minimal damage and the flesh just snaps back. However, if the round moves fast enough, the displacement of the flesh exceeds its ability to stretch, which can tear it apart. This only happens with high velocity bullets, generally rifle rounds moving over 2000fps.

Subs, of course, are limited to under ~1125fps. They move too slow to do real damage with the temporary cavity. Thus you are left with the permanent cavity, which is the hole the bullet actually makes as it moves through the body.

Here, energy does not matter nearly as much, it's really down to bullet design. In fact, energy can be a hinderance and limit energy transfer, in addition to potentially nailing the neighbor's dog.
That's what this anon >>64120748 meant when he said
>300 Blackout's main problem is the bullet diameter is so low yet the sectional density is so high you are inevitably just going to ice pick a 30 caliber hole through the target with subs
It's just not going to expand as well as 9mm can, it's not going to leave as nice of a wound channel, and it's not going to transfer energy as well.

Kinda pedantic/fine points but

>Shockwave causes TSC
Not really the case, TSC is caused by tissue being accelerated away from the projectile but this is not caused by the "shockwave" of the projectile. At least not in the sense of an actual shockwave which propagates at the rate of the speed of sound for the medium in question. TSC formation happens at around 8-12% of a projectiles forward velocity, it's really just the tissue being accelerated by the energy being deposited in the tissue.

>2000fps
Most rifle rounds begin to produce meaningful TSC around 1800fps, with larger frontal areas you can see this happening at much lower velocities. This is true down to at least 1500fps and can be seen both with shotgun slugs and was well documented with older large bore military/hunting guns in that velocity range.

That is what you asked. You asked (in a passive aggressive manner, typical of a female) if those impressive results were from shooting an animal, or gelatin, so that you could then say "they may perform well in gelatin, but what about creatures, such as humans?" And to that, my answer is that every single picture of an expanded bullet you have ever seen in your entire life that is used by the MFG to tout their performance, was achieved by shooting gel.

Other than hunting cartridges, I've never seen a bullet recovered from a creature, excluding Paul harrel's meat targets. We should probably just assume that no hollow points work at all until we have personally gunned down a 'groid and recovered the bullet. I have never done this with .45, so I have no reason to assume it expands better than. 300blk.

Manufacturers of bullets realistically cannot go around shooting animals (or even corpses) just for advertising purposes. That is a big no-no. Even the government stopped experimenting with shooting sheep cadavers a long time ago.

I don't buy copper bullets because expansion results from ballistic gelatin shot in laboratory environments are not realistic representations of real-world performance.

Your assumption that "300 blackout subsonic actually does expand" might be true, but in ballistic gelatin or water jugs only, and animals are not gelatin or water jugs.

As you know, hollowpoint expansion and reliability are based on the type of bullet. Some suck, some are great. The original claim was that .45 expands better than sub .300 blk. So, you're going to have to show me these bullets of various manufacturers recovered from animals for the original claim to have any weight. Unless you trust the gelatin results for .45, but not for .300 blk?

A larger diameter bullet can and thus will expand to be larger than a smaller diameter bullet, all things equal. This is a simple mathematical fact that is true for both gelatin and animals and requires no photographic examples.

.300 blk projectiles are longer, that means that the "petals" reach out further. Assuming that they do expand as well as those pictures, do you have any reason to assume that it's less lethal than an expanded .45 slug? The diameter of that star is fuckhuge.
>a larger diameter bullet can and will...
No, many bullets completely fail to expand. This used to be a problem with 9mm and is still a problem with .380.

False, it is superior. 300blk has superior ballistic coefficient to 7.62x39, with a greater variety of bullet options. Additionally 300blk supers do better muzzle energy with less barrel length than 7.62x39 does. Compare for example a 9" 300blk to a 9" 7.62x3

You can use 308 in x39.

Fucking horseshit, x39 has more case capacity, it makes more energy at ALL barrel lengths.
>Compare for example a 9" 300blk to a 9" 7.62x39
Factory ammo? So you're cheating the comparison because you know the .300 will be loaded with faster powder. Otherwise, no, more capacity enables either more speed at the same pressures, or the same speed at lower pressures, always, no exceptions.

>>64120589 (OP)
The only (and I mean only) 223-compatible cartridge which does this hybrid sub/super game well is the .277 wolverine. .277 is the smallest common bore size at which super-heavies;
>take full advantage of the available powder column (no excessive cutting back of the shoulder)
>fit in the 2.26" COAL
>are naturally subsonic at full pressure in short barrels
All the things which people claim the 300blk is good at are just better at a smaller bore size. More energy at range (and virtually equal at the muzzle due to just better efficiency), less recoil, flatter trajectory, less wind deflection, better suppression, and all of these advantages apply to both supers and subs.

300blk (and 300whisper before it) is 30 caliber because of the mere existence of 7.62x39 and 7.62x51, and NO OTHER REASON. It is way off optimal, "30" is just a bore diameter stuck in the military and gun owner psyche, there's no engineering justification for a 30-caliber small-frame AR cartridge based off the constraints of the 223 case head and STANAG magazine.

>Fucking horseshit, x39 has more case capacity, it makes more energy at ALL barrel lengths.
>case capacity
Once again, no one gives a shit about your gay reloading hobby boomer. Factory ammo to factory ammo, for the barrel lengths of interest (7-9"), 300blk has more muzzle energy (supers). And no one gives a shit about 11-16" barrel lengths in a 300blk discussion because said long barrels entirely defeat the purpose of a short subsonic/supersonic capable rifle.
>Factory ammo? So you're cheating the comparison
>Factory = cheating
What the fuck are you going on about? For literally 99% of of shooters factory ammo is all that we care about or consider, and guess what, factory supersonic 300blk beats out factory 7.62x39 in barrels 7-9"
Deal with it.

Also this entire conversation is fucking stupid because 7.62x39 doesn't reliably cycle subsonics in short platforms of any type, 300blk does. The entire point of the cartridge was that you can hot swap subs to supers in a tactical situation.

You can do all of the things in a very small package, that is still accurate enough to engage targets at realistic ranges. 9mm has terrible dispersion, external and terminal ballistics are bad. 110 supers destroy shit, expanding subsonics for low vis shit. AP an option.

The compromise is the use of supersonic bullets. .300whisper was designed for subsonic loadings, 338ARC optimizes for that at the expense of supersonic memes. 8.6 is just a product improved version + lessons learned.

300blk is a terrible supersonic rifle cartridge. And I know linguistically "supersonic" is only half of the whole, but in reality speed kills, and the vast, vast majority of rifle uses are with supersonic projectiles.

Supersonic .300 BLK is more or less 7.62x39 or .30-30. Subsonic, it's more or less .45 ACP.

This is seriously underappreciated. Have you seen how wide 8.6 blackout maker rex bullets expand in gel? Itโ€™s like >1.3โ€, easy. They also trace a beautiful triple helix in gel, which, at least in principle, would increase the chances of a vital hit.

NTA. 8.6 blackout (supersonic) in its current incarnation is nothing to write home about. But in a hybrid case, with light-for-caliber VLD bullets, it turns out the 8.6 blackout has the right ogive space and the right overbore ratio to be something like a CETME cartridge, so it would be pretty cool and useful that way. Its present supersonic performance is shit, and subs nerf it even more. 338 whisper stands out from the rest of the lineup in that it has a huge case for its caliber and so is better optimized for supersonic loads. I wouldnโ€™t t look at an 8.6 blackout, not knowing what it is, and say โ€œyeah thatโ€™s a subsonic cartridgeโ€.

Iโ€™ll concede the twist rate does seem to be very useful for subsonic expanding bullets but really limits supersonic velocity. How fast can you go before bullets starts ripping themselves apart in flight? I know the supers right now, at a velocity of low 2000โ€™s, are doing like 500,000rpm, which is a fuckton of angular velocity for a .338 bullet,

Not completely. Itโ€™s a great idea for extracting money from clueless zoomers that are too young to have heard of the 358 Winchester, which does everything the 8.6 does better, does it for cheaper, and has been doing all of this for over half a century.

I think Q o can start a whole industry around poorly duplicating obscure old chamberings using meme twist rates and less common parent cases, just as long as the marketing and YouTube shilling remains effective.

Out of short barrels 7-9" comparing good supersonic 300blk loads meant for hunting or shit, vmax etc to like good military loadings for 7.62x39, vympel etc, 300blk has better muzzle energy and both external and terminal ballistics.

Wow. I wonder what happens when you load 7.62 with the powder used in the 300blk loadings.
If forced to choose I'd take 300blk over 7.62 just because one is dying out (for good reasons) and the other isn't (for bad reasons), but retarded comparisons like that are the reason the cartridge world is full of junk, like the entire ARC/Grendel line, and everything based on 30 Remington, and 400Legend (if you believe Winchester's bullshit about it somehow NOT being based on the 30rem/6.8SPC).

It's more comparable to 9x39 not 7.62x39. The two even look almost identical in dimensions. Even supersonic, neither are as good performing all around. The bullet is too heavy, the 7.62x39 can zip faster and shoots in a straighter arc. Those rounds are designed specifically to be used subsonic, no real point in using them otherwise.

They should make more subsonic 7.62x39 so at least you can switch between ammo types and have a good all around performing intermediate.

Well, if you use a .308 intended projectile in a gun built for .308 then you'd get ice picking and failures to function. If you use .300 blk projectiles then you now have a shitty .300 blk performing rifle using a larger framed receiver for no damn reason and requiring considerable modification for reliable function.

Wrong again, 300blk supers do excellent out of barrel lengths 7-9" where 5.56 falls flat on its face, and 7.62x39 isn't ideal either.

are you a child? I spent a minute trying to figure out what that word is between โ€œ0.36โ€ and โ€œBCโ€ because it did not occur to me that someone who is ostensibly not a child would capitalize the 2nd letter of a word.

Anyway, with that out of the way. Do you buy those cartridges or do you load NAS3 cases yourself? Have you compared them against regular brass-cased loads? 120gr@2380fps is quite impressive for 300 blackout. Whatโ€™s your barrel length?

>subsonic 7.62x39 can't cycle short platforms
All of the factory x39 sub loads cycle in my 9.5" barrel
The biggest issue with x39 is a lack of bullet development. You basically have SST or Barnes for domestic factory ammo, and those are not optimized for subs. Hornady had an opportunity to build a quality heavy for caliber bullet with the 255gr subx, but it doesn't expand beyond 9mm at subsonic velocities; a total abortion of a bullet
>>64129197
These bullets and the 130s are excellent hunters. The 130s can be loaded in x39 with CFE BLK

>7.62x39 i think you could also just do a barrel swap but youd need different magazines
Nope, need a new bolt and extractor for the wider rim as well.
On the other hand, different magazines aren't -entirely- necessary. A 5.56 mag can have some limited function with a 7.62x39 rifle and ammo. The mismatch doesn't add up into a problem and it tends to work, if you only load three or four rounds. That could be enough to get the job done in a pinch.

I've killed many a coon with a Glock 21 topped with one of these and wearing a suppressor.

It's a'ight. Only drawback is the lack of reliable extended mags for the G21

.45 has been held back by either being chambered in outright shitty weapons, inconsequential weapons like sidearms, or weapons to which there were just better alternatives.

>WW1
>Used in 1911s and M1917 revolvers by Americans for the last year of the war, so basically irrelevant

>WW2
>Used in the Thompson by the bongs when they were caught with their pants down without a proper smg
>Used in the Thompson and Reising by the US but very quickly eclipsed by the first proper intermediate caliber self loading rifle, the M1 carbine
>Finally used in a decent SMG when the M3 grese gun entred service, for a short period at the end of the war

And by vietnam .45 ACP was truly irrelevant, there were still loads of M1 carbines in service and ARs were starting to enter service.

Also tilting barrels suck ass and the 1911 should not be as popular as it is, tilting block below the barrel is the superior short recoil mechanism, and the germans figured it out with the Mauser C96 already, Walther made it mag-in-grip with the P38, and Beretta made it sexy and double stack with the 92 series, the beretta 92 is the pinnacle of handgun design and I'm tired of pretending it isn't
