The juice is simply not worth the squeeze.

mechanically hard to do, no point in doing it really.

>>64394390
if you want more power, you just use a bigger cartridge
sure, obturating cartridges are cool as fuck (i say that as i own a 1895 nagant), but for an entire military to adopt them is honestly silly - especially when the standard shooting stance was onehanded at that, and without even having a single muzzle device of any form either

>>64394390
Revolver users care about using revolvers and that's literally it. If you want anything other than to use a revolver, you get an automatic. No reason not to

>>64394390
>maximum bullet velocity
estimates of the nagant gas seal place it between 10-20% more muzzle velocity compared to an open cylinder
the number of situations where this might practically affect you is negligible

>>64394390
>but with modern engineering precision you could easily make a
Every faggot that's never worked in manufacturing really does think it's this simple

>>64394403
>mechanically hard to do
Not exactly. Yeah maybe it would take a few more components to work but then stuff like barrel unalignment would be less of an issue. With recesses on the cylinder's front or the barrel's back it would be self correcting. So more components would be needed, but less manufacturing precision would be required.

>>64394425
But automatics also suffer from gas escape, though a bit less bad?

It would be too expensive to manufacture for what little performance you would gain for keeping the gas seal, plus as former anons have already stated, if you want a stronger/faster bullet, you can just move up a caliber.

>>64394447
Depending on the semi autos action, it would still be far less then say your average revolver

>>64394447
They do? How?

We have to also consider the market for this would be microscopic. You're better off opening a vegan and gluten free only restaurant than trying to market your idea

>>64394461
Gas pushes the slide back. Even when the ammo would have left the barrel before the gas leaves the chamber, the chamber would still expand and the pressure would be reduced.

>>64394390
There isn't really a need for it and the engineering is complex, with a lot of trade offs such as a horrible trigger pull. The only tangible advantage is being able to use suppressors, which can already be done much easier on an automatic.
>>64394444
More components means more tolerance stacking, which means higher odds of it not working or at least not working reliably.

That means extreme cost and some lingering reliability concerns if not done right, or a really horrible gun with specialized ammunition that sucks to use like the Nagant.
>>64394447
No? Where did you get that idea? Are you talking about gas blowing around the case if it doesn't fully seal around the chamber?
>>64394466
Well, goofy shit like the Mateba exists. It could be done on a small scale and sold as a novelty to collectors in tiny numbers, especially now that suppressors will be more of a thing.
I wouldn't invest my money in that business though.

>>64394390
Complicated mechanism and significantly worse trigger pull for a 5-10% performance gain at most, depending on the ammo, and better suppression. I don't think that the market would support that.
>you could easily make a mechanism that makes the barrel slide backward instead of the cylinder sliding forward
Fuck, that sounds harder than making the cylinder move forward.

>>64394476
>what is obturation
You don't know what you're talking about, but I'll give you a hint: by the time the cartridge case is even thinking about starting to move, the bullet has already left the barrel. Whether or not the slide has started to move is completely irrelevant.

>>64394476
certainly not in any locked breech gun. maybe in a fixed barrel handgun like a ppk or cheetah this would happen but it would be nominal and not have any measurable effect on bullet velocity

>>64394480
>It could be done on a small scale and sold as a novelty to collectors in tiny numbers
I agree with this sentiment, but then you end up with a situation like when they made new Webleys in .357 or whatever, and people like me never find out they existed til way too late

The only positive would be that you could effectively suppress a revolver like this. Surprised this hasn't been mentioned in his thread already.

>>64395064
It has been...

>>64395084
no it wasn't or I wouldn't have said what I said

>>64394390
You need the special telescoped ammo to make it work and people don't like proprietary cartridges.

>>64396137
>You need the special telescoped ammo to make it work
no u don't dumbass just push it in harder. how do you think people shoot .45 ACP out of .410 shotguns

>>64394390
I have never fired a revolver and felt like the bullets weren't moving fast enough lol

>>64396631
I think vidya drives the min/maxing (or whatever it's called) logic. The thought where if there's still .085% optimization possible remaining, you MUST throw everything else aside and fund the "better" thing

>>64396631
try shooting a real man's gun not that pussy 454 cassool shit

>>64394390
Only use case is to suppress and use it to murder someone since it leaves no shell casing. No military or civilian use case unless you're Mossad or a Brazilian moped rider.

>>64396619
Are you mentally deficient?

The real, actual reason is that the Nagant action is lost technology, similar to the Mateba, another "alternative" revolver design with its own benefits, or like the G11.

Everything is getting shittier and dumber and we will likely never go back. Literally the most cutting edge thing we have right now in the firearms industry is... 3D printed metal tubes. Wow, incredible.

I suffer from gas escapes. Especially when the chowhall serves burritos.
