    Would it be possible to build a revolver for 7.62x39 and keep it small like a k frame smith? Obviously the cylinder would be longer but would it have to be overly beefy? Just curious.

    IMO it would require such a long cylinder that it would defeat your purpose of size and compactness. Bottlenecked rifle cartridges generally do not function well in revolvers, having problems with the case heads pushing back against the recoil shield and preventing the cylinder from rotating. Finally, the flash gap and muzzle blast would surely be quite spectacular, but not doing much to push the bullet all that fast. ;)

    There is/was a company from Indiana that made a SAA in .45-.70 so it could be done, but it would be a big SOB.

    The answer to your question is, no.

    Revolvers and high-pressure bottle-neck cartridges do no play well together.

    When fired, the case slams back into the recoil shield on a revolver, and expands there.

    Then, the expanded bottle-neck shoulder prevents the case from sliding back forward in the chamber to free the cylinder to turn.

    That's why the straight wall 45-70, and other high intensity Magnum handgun rounds work so well, but little bitty bottle-neck ones like the old .22 S&W Jet didn't.

    Yep, high pressure and bottleneck case do not work in revolvers.

    It would be a fun pistol though, a real firebreather! :)

    ADC made one of their derringers in the caliber and as I recall from the pictures it was a fire breather.

    Ballistics out of a short barrel would probably equal those of the Blackhawk 30 Carbine, so why not get one of those?

    Well, there was a revolver made in 5.45x39. I think it was called the Yesaul.

    Well if you has a shallow enough bottle neck they work 32-20, You can stoke them up pretty good. I wonder if you got a super steep shoulder like an AI 40 degree would work. Like a 223 AI 40. But there wouldn't be a whole lot of point to it. You would loose a lot of velocity between the short barrel and cylinder gap. I will keep my Encore pistol for rifle rounds.

    What happened to the 223 revolver that Taurus announced? Guess it was vaporware.

    Well if bottleneck cartridges don't work well in revolvers, what about the Magnum Research bfr in 30-30?

    I'm not sure with the .30-30, but Magnum Research specifically mentions 7.62x39 in their custom section, noting that it's a really bad idea.

    bottle neck?

    Some body better tell my revolvers chambered for bottle neck cartridges that they don't work. Up until now they have been working just like my revolvers for straight cartridges.

    The only bottle necked cartridge I ever heard of giving trouble was the 22 Jet which was a classic case of the biggies taking a wildcat commercial and fixing what wasn't broke. The inspiration was the 22 Harvey K Chuck which worked fine. S&W & Remington switched the basic case which would have been OK. Problem was that they stretched out the shoulder to a ridiculous length and created the set back problem.

    There is a long list of bottle necked cartridges over the years that have worked fine in revolvers.

    Drawback to the 7.62 x 39 is that it's rimless which means a SA or moon clips.

    The OP wanted to know if he could get a 7.62x39 in a K-Frame size gun.

    Answer that any different then I did!

    The answer is still No!

    Frame for 7.62x39

    Taurus has a 45 Colt/410 revolver that might have a long enough cylinder. As I recall the frame is not overly large. I haven't paid enough attention to the 7.62x39 to know just exactly how long it is. A drawback here is that an over sized case full of slow powder in a revolver is a recipe for erosion. Witness the hoo rah over the 357 Maximum which was another example of fixing what wasn't broke. It's inspiration, the 357 SuperMag never had this problem and it's LONGER than the 357 Maximum.
