The japanese had this weird thing where when they copied guns they tended to make them better than the original, like I forgot what its called but the jap version of the zb 26 etc. The japs had some real stinkers for weapons but on the whole they were exceptional guns.

Iirc it was their tanks that were really garbage.

Japan had issues with their tanks more from the army/navy rivalry and the whole amphibious island campaign. Their shitty tanks worked great against the chinese who didnt have modern tanks at the time. But when you are in a shitty tank you dont have much chance against a sherman from a mile away.

IIRC they never really thought much of it because of their infantry doctrine.

They did pretty well against stronk Soviet tank in Mongolia, too.

It was kind of all over the place, some guns were good, some were subpar. Their main service pistols for instance were kinda shoddy (though thankfully for them, pistols don't matter too much for warfare anyway). Really, their logistics and tactics were the primarily retarded part, they could maybe have gotten away with having almost no subguns if they weren't so braindead set on the whole "warrior spirit" thing, used their brains more, and if they put more effort into supplies and supply lines, additionally they should have understood the absolute danger that the interservice rivalry was to their success, and cracked down hard on that shit before even going to war.

Go read up about Imperial Japan's attempt at conquering India, that shit is unbelievably funny.
 
>it was entirely possible to get a mobility kill against a Japanese light tank with rifle fire
WTF WERE YOU DOING, JFC
Every time I learn a new thing about Imperial Japan's military forces, it's usually funny as fuck.

I'm a lay person, so I don't understand the engineering behind the Serbu gun, but the idea of shooting surplus .50 SLAP ammunition through a gun with a screw cap seems like peak autism to me.

I feel like it was naivety on KB's part. Serbu says you can shoot SLAP rounds out of it just fine so I guess KB just assumed it would be safe. I thought that piece of shit gun was sketchy from the start given the whole threaded end-cap aspect plus the fact that Serbu apparently put so little thought into it that he didn't even include a way to extract the round. But there are several big gun youtubers who use it (ie Demolition Ranch) which would make it seem okay enough.

I think maybe this should be a bit of a wakeup call to people to not just shoot whatever the hell some retard puts together. Especially not when that means hoping a threaded cap can contain pressures of 55,000 psi. And on the topic of psi, Serbu said that cartridge needed to have 85,000 psi to shear off those threads. The main gun on an M1 Abrams fires rounds with a pressure of 70,000 psi.

Moral of the story, don't be retarded and don't immediately trust what people tell you. Make sure you know where your ammo is coming from and don't trust some dude who says his sketchy ass pipe gun is safe to fire sketchy rounds out of. Otherwise you might end up with some metal threading being the only thing separating your face from chamber pressures exceeding a tank round.
 
The threaded cap DOES withstand 55k PSI though, because lots of people shoot it and this is the first one to ever explode, 85k PSI just isn't that thin of a margin. The design could be better (such as featuring vent holes on the breech cap, something which would probably not be difficult to offer as a retrofit if necessary), but I'll remind people that old shifty SLAP rounds have ruined Barrett rifles and injured shooters of those, even if perhaps not as badly.

Mind that pressure is force divided by area. So when the main gun on the Abrams generates 70,000 PSI inside the forces are huge because of the area involved.
70,000 PSI inside a 10x smaller gun is dangerous, but hardly impossible to deal with.

It's almost like that was the point of my post.
 
Honestly the RN50 seems like a fine design. Threads are slow and kludgey, but there perfectly safe. Shit the barrel is threaded into the receiver on most guns. I'm not sure that anyone should be shooting SLAP ammo out of anything, it seems to be expired - for lack of a better term.
 
I had this argument with a coworker; it's not the rifles fault that some retard bought long out of production ammo meant for heavy machine guns and fucked around with it in a rifle not designed for it and found out. There's absolutely no way Serbu can be found at fault for this shit, he didn't design the rifle to fire shit meant for an M2. As for the whole threading thing, like the first two threads take about 80% of the pressure. Everything after that is miniscule. Yeah, it sucks that the cap blew back like that and so hard, but once again not fucking designed for that ammo or those loads.

Remember at that time the soviets were at the height of the purge. had only bt 5/7 and t26's. And the absolutely horrid tank/infantry coordination.

The tanks would just fucking drive off leaving the infantry behind and do really whatever they wanted. They also didnt have radios and only 2/3 man crews. Just look at what the finns did to the soviets years later to get peak meme.

Is this a dig on Ian making a video? Or guntubers as a whole?

I would very much like Karl from InRange TV to explain to me precisely what other scenario besides a barrel obstruction creates stresses that fucking high.

Also if he knew anything or was paying attention to the conversation at all, he’d make note of the fact that something like a threaded end cap stripping threads is a shear failure mode.

Shear capacity and tensile capacity are not the same thing, and it’s not just semantics.
