12.7 x 55mm STs-30

This seems like a very weird round, as far as I can read it's used in everything from handguns (In the RSh-12) to ARs (ShAK-12) to bullpup sniper rifles (VKS Rifle) Also, what's the point of a double-bullet
>Dvukhpul'niy (DP) or "Double-Bulleted" - Two bullets loaded inline weighing 17 grams (262 grains) each.
Second from the left in the picture. Anybody here that has shot the round before or has any experience with it?

    duplex bullets aren't a new idea

    Double bullets are one of the few ways to increase hit probability without using meme rifles.

    Duplex bullets have been around, as well as comically large revolvers. There's a few .50 BMG (12.7x99) handguns out there.

      But it seems like the russians basically designed this cartridge to be all-purpose, there are sub and super-sonic loads, loads for revolvers, loads for AP out of marksman rifles etc. Is there any western equivalent?

        Closest I can think of is .510 Whisper.

        In my opinion the one thing this round does well is be a supressed sniper rifle. That's really what it's designed for. The other rounds really feel like they were afterthoughts to get more use out of the cartridge, but if you're not trying to be sneaky silent there's really no point to using this cartridge.

        >they're all at 300 m/s

        Maybe. Or they're all designed to be subsonic.

        >loads for revolvers
        AFAIK there is no specific revolver load, just a meme revolver that shoots the assault rifle cartridges. The thing is, if you're going to design a cartridge for short-range subsonic use, there's not that much of a difference between a pistol or a carbine or a marksman rifle. You could probably say .300 BLK is just as versatile. The "pistols" are all just short-barreled ARs, but it's not like they're any memier than a .50 cal revolver.

          But I can't think of any revolvers chambered in .300 BLK or .458 SOCOM

            No, because revolvers for rimless cartridges are memeguns 100% of the time. Exactly the same reason the RSh-12 shouldn't count as anything but a meme.

                It means it's only made as a publicity stunt and not intended to actually be used, even if it actually works. Same shit as .700 Nitro Express or .50 BMG pistols.

                I'm not sure what you mean by that. Would it go bang? Sure. The important question is what purpose does this particular gun serve that another gun can't do better? It's much too big for concealed carry or as a duty pistol. The cylinder gap negates any potential supressor use. As a PDW or even in rifle configuration it has very limited firepower compared to other weapons of similar size and weight. It's difficult to think of a situation where the RSh-12 would actually be the optimal choice, or anywhere close to it really. In a precision rifle with a suppressor? That has a niche as a super quiet urban sniper weapon. But a bigass pistol that's both bigger and weaker than a .500 S&W, another meme pistol? Just what for exactly?

                At least it looks fricking cool.

                the russians have a unique problem of groups of ultra-nationalist terrorists with soviet surplus armor taking large numbers of people hostage in urban areas. they're for shooting people at close/medium range in populated areas. they were designed to be suppressed, to maximize stopping power, and to penetrate armor, in that order. its the same idea as the 9x39 in the vss/as val but bigger.

                the cartridges for the vks have much longer and more massive bullets and they aren't compatible, just fyi

              Because moon clips exist, a .300 blk revolver actually seems pretty cool.

                You can go down to 8" before .300 blk starts shitting itself. That's not super crazy in the world of rifle caliber revolvers.

                bottlenecks are dogshit in revolvers because they elongate and can cause jamming of the cylinder.

                What, like the brass extending past the cylinder? It would take an entire inch of case deformation for that to happen.

            you could chamber a BFR in either I believe, definitely at least .300 blk
            so there is no equivalent, but not because it's impossible or even far out of reach, it's just that no one thinks its worth doing

              They do list .350 Legend, and I know at one point they made .50 Beowulf as special-order. I'm 100% certain they could do .458 SOCOM.

                I'm sure the gun is strong enough to handle it, but .458 Socom is is a bit of an odd duck: its rim diameter is much smaller than the diameter of the base of the case. That's fine in an AR where there the bolt face has a recess in it for the rim to fit into. However, in a revolver that doesn't have a bolt? Now you have part of the case head unsupported.

    The revolver rifle monstrosity that chambers that round has to be the coolest thing I’ve ever seen. That’s what I’d carry on the neon streets of night city. I’d put a big obnoxious can on it too just cause.
