It should fire just fine but it won’t last as long as a proper barrel, and it also speaks to the general poor quality and state of Russian manufacturing.
Something that the lives of their soldiers depend on should not be coming out of factories looking like that in the year 2022, especially in a country like Russia that claims to be at the forefront of every technological field.
It's not really an issue. In engineering there are these things called clearances. It may be that the thicker wall is the bottom of the barrel and is a utilitarian attempt to mitigate droop on a platform that doesnt have a top end laser system to do that, but I'm really just guessing
It's my understanding that when you're boring deep, you turn on live tail stock last to ensure concentricity. I'm told that these weapons are laser bore sighted, so accuracy may not be an issue, however the barrel life is expected to be shortened due to flexing under heat and stress of repeated firing. Idk.

what about barrel harmonics? I know when fired barrels flex like when you hold one end of a rope and make a loop with your arm. wouldn't tolerances this loose completely frick up any kind of accuracy?

I don't know. On some level, barrel harmonics sounds like some bench rest voodoo bullshit, but it would seem that it must have some effect, however miniscule. It's my understanding that harmonics could play a factor, as the zero of a non-concentric barrel may "walk" more under heavy use given that the mass of the barrel is not equally distributed. Ie, one "side" may heat/expand more than the other, which in turn may cause premature wear.
But, ultimately, does this really matter in a combat scenario where "good enough" actually is? Idk. Was hoping some big brains could weigh in.
It doesn't matter so much on combat rifles. Harmonics only become a big deal in precision shooting. Generally speaking it doesn't matter at less than 300 yards and that's where most firefights happen

Barrel harmonics are real, but it's really only for teasing sub-moa accuracy out of a precision rifle, and the thicker the barrel the less it flexes. I'm pretty sure that for a tank it would have such a miniscule effect as to be unmeasurable.
Clearance is one thing, this doesn't have to do with them. Frankly, besides the Reddit post I wasn't able to find anything more about this.
Could be a manufacturing error, a discrediting post or maybe the soviets were onto something big when they tough of this.
Rumor circulating around the Kremlin is that they're just one or two more "gotcha" posts away on PrepHole from throwing in the towel and withdrawing from Ukraine.
It would help if the website wasn’t co-opted by whatever faction could muster more than 10 IPs on a given day for whatever flavor of the month geo-political issue. For fricks sakes they were even creating new accounts on AR15.com just to shill pro Russian shit. Please leave gun owners alone
Maybe they understand what a realistic lifespan for the vehicle it's going on is and build it to standards accordingly. If you can make 2500 barrels that last a third as long in the same time you could only make 2100 barrels to proper standards, but the expected vehicle service life is an eighth the barrel life anyway then it could make sense to drop qc to turn more out.
Soviet manufacturing was usually pretty 'meh' on tolerances in the sense that it was scaled up so big that if you have dumbshit machinists churning out say, 100 barrels a day, you're basically paying them in room + board + crippling alcoholism so you're not expecting much. If you have to discard 10 barrels out of that and send them back to be re-melted or discarded, stuck up someone's arsehole or whatever, then it was more or less just part of doing business so to speak. Plus there was some endemic corruption in the USSR in the sense that if the QA-inspector was very drunk, didn't give a frick or signed off on all but the worst duds they shat out of the mill, then you've met your quota and dodge the gulag vacation for a while longer.
To some extent miners, refinery workers and qualified machinists had some degree of protected species in the Soviet system because its either a fricking awful, dangerous job no one wants to do or requires a fair degree of skilled workers to do. They're just not really in the vast quantities that meant you could slaughter a lot of them and get away with it.
Zee problem Russia has is that its not really so much making vast amounts of stuff any more. Their arms industry does a lot of stop-start manufacturing when there's a demand for whatever it is, but they're not producing the vast amounts of shit that used to give them some leeway for wonky barrels and other rubbish that was covered by it, plus by virtue of making enough of something, you get enough of them 'good enough'
So those factories and workers are more or less just whoever can run whatever, on the day, when needed
It is not an acceptable barrel in any armed forces outside of Africa or the ME
I'd take one look at it and decommission the weapon system if back in the day one of my dudes was checking their gear for tolerances, then I'd beat the literal frick out of whoever issued it
Well, of the top of my head , the barrel is gonna heat up disproportionaly and warp to one side. Where the wall is thinnest, the grooves will wear out faster. Maybe issues with zeroing the gun, or stabilisation when firing. Also again accuracy suffers because of recoil harmonics.
Ever since the war started, this board that previously largely believed in the idea of facts backed by evidence and aversion towards propaganda, has devolved in believing everything without a shred of evidence or nuance, and has Two Minutes Hate on repeat.
To raise the expansion caused by heating on the bottom of the barrel to counteract some of barrel droop. More material on the bottom will expand more pushing the barrel up a little bit that counters some the droop you get from the hot barrel.
Copypasta from Reddit and the other thread about this
This reeks of propaganda. Why is the barrel so smooth? Unpainted? No wear at all? And so clean too. Allegedly it was cut in half but why? Why are there concentric scratches from the machining process instead of the straight scratches a saw would leave? Why is this "shopworker" wearing sandals and not steel toes? Assuming this isn't cut in half, why is the end of the barrel (muzzle or breech) not machined at all? The muzzle would be threaded for a muzzle device and the breech would be keyed for attachment to the turret. Those markings are industry standard non-conforming markings with appropriate photo evidence to be sent back to the manufacturer. And as many people have asked, how do we know this is even Russian when Ukraine uses the same equipment?
It looks like you got meme'd on and/or are spreading bullshit to farm karma because "Russia bad". You can't trust anything coming out of Ukraine and they've been caught in outrights lies many times now. This seems very obviously to be just a non-conformed, unfinished barrel blank with no evidence to suggest that this has ever been used by the Russians, not to mention ever been fielded.

I shouldn't have to qualify this comment by saying I don't support Russia but it's not like you dipshits would believe me anyways.
He's right, and it's pretty pathetic to imply anyone criticizing Ukraine is a vatnik, the country isn't untouchable because it is at war.
On the contrary I'm not seeing a lot of people question why this picture is posted all day long without context. It's what, the sixth thread in two days? With at least two concurrent threads at all time? >t. John, Kentucky oblast
Why is this line spammed everywhere by thread derailers?
If you're denying that Ukraine has been caught lying multiple times, there's nothing I can say to convince you. You're just here to derail the thread anyway.
pretending there's moral equivocacy between an invading force that rapes and pillages as a SOP, and a defending country that's been politically predated upon by it's invader is the most heinously disingenuous bullshit to have spilled forth from the frothing bucket of shit that is russia in at least a year or two.

noo but both sides ree
Yes, you morons in particular are just as bad as the vatnik copers. Anytime you get called out on your bullshit you have to deflect and deny with sarcastic "both sides" comments rather than just admit that you're propaganda is just as shitty and easily disproven as Russia's. Ukraine cucks are fricking pathetic. Go sign up for the Leddit legion if you want to be so defensive about Ukraine.
Russians and real vatniks never say "both sides" anyway. Either they deny, joke about it or deflect, but never will they admit any wrongdoing, even with a "both sides" argument. That sarcasm doesn't make any sense, it's something tourists came with.

Bullshit, it's a typical step in the Russian disinformation sop. Which fyi is deny, lie, excuse, whatabout, cope. This is the 4th step.
Example >we never had plans to attack Ukraine >those are just exercises >well it's a special operation because nazis >whatabout iraq eh >anyway this is a glorious struggle
Or >Moskva totally isn't sinking >Moskva is sailing to port as we speak >well someone was smoking near the ammo locker okay >whatabout the rest of the war we're still winning >anyway we're fighting all of nato
Or >we never committed war crimes >those bodies were put there by CIA >well they were terrorists okay >whatabout Ukrainian war crimes >anyway shit happens in war
Etc etc

Whataboutism is not about recognizing your wrongdoings, just accusing the other of doing what you are accused of while denying. This is why the "we are liars but you are lying too" is stupid.
Never will a Russian say the first half of this sentence, only the second.

>Whataboutism is >just accusing the other of doing what you are accused of
Yes >while denying
This part is optional
Because the core concept of whataboutism is to normalise said behaviour and thus tacitly excuse their own. Usually, a mitigating excuse is offered up whenever Russia is unable to come up with an adequate denial. The whatabout example will be devoid of excuses in order to magnify blame.
>Never will
Mainstream Russian shills do it all the time, and so does the amateur brigade. The latter probably because they picked up from the former, the former because they have a well-thought-out script. Not that it's that difficult a concept, it's pretty intuitive.
Classic example >no we never shot down Mh17 >it was a Ukrainian fighter firing an R73 >yeah well it could have been anybody's Buk >whatabout Vincennes >anyway shit happens in a warzone
Oh, a related one >no we never bombed civvys we do not use Tochka anymore >it was a Ukrainian false flag >the civvys were near military equipment >whatabout Donetsk >anyway it's a warzone, shit happens
The pattern is exceptionally obvious on RussiaToday and any Russian MSM. Which of course are directly controlled by the Kremlin.

Wear in materials as thick as a barrel will never affect guns ubless you intend to shoot like 5000 bullets.
Steel wear affects shit like small mechanical pieaze specially stuff tha rotates
