Okay here is my stupid question for the month. Would it be conceivable to make a revolver that shoots 7.62x39 (or it could be .223)? The pressure levels are in the same range as the S&W 460 and 500. It would be expensive mostly b/c they would have to machine the cylinder chambers to the shape of the rifle cartridge and not just straight through but you could end up with probably 7 or 8 shoots in an X frame size gun. Practical, maybe not but pretty cool.

Makes me wish I was the owner of S&W, “hey guys put this 7.62x39 into that gun and see what happens.”:D

I thought about throwing in myu two cents about how I always thought something like that would be cool and all that, but everything I was thinking about saying was already said here http://www.thehighroad.org/archive/index.php/t-16580.html

Told you it was a stupid question.

If they can make a .45/70 revolver, a x39 revolver is certainly possible.

probably sell some of 'em to folk that own that chambering in a rifle/carbine but seeing as how there is an AK47 semi-auto pistol doubt it would break any sales records.

Bottle neck cartridges haven't worked well in revolvers. They tend to set back and jam against the recoil sheld.

This is the main reason why these aren't made. S&W tried to market a revolver for a bottle-necked cartridge (the .22 Jet) and it failed for this reason.

Because of the tapered case, the same problem existed for non moon-clipped 9mm revolvers too. I say "existed" because S&W solved the problem in the Model 547 revolver by adding a pin (that looks like a 2nd firing pin) that pokes through the recoil shield and forces the case back into the cylinder.

Whether or not they could do the same thing with .223 or 7.62x30 remains to be seen. If they made a .223 X-Frame, I'd buy it in a heartbeat.

Taurus announced that they would be making a .223 revolver at this year's SHOT show, but I haven't heard anymore about it; if they managed to get over the "set-back" problem in .223, there's no reason they shouldn't be able to do it for 7.62x39 as well.

any of you heard of the 7.62x 25 round?

Nasty little bugger the commies used form 52 to 73.

Slow burning rifle powder is made to burn up completely at the same time the bullet exits the "rifle" barrel to accelerate the bullet throughout the length.
Seems to me a large percentage of the powder would not be burnt, thus wasted, coming out of a pistol or wheel gun.

Just my theory????

why does'nt someone chamber 7.62x25? in new firearms?

For set back, then how about an 1895 Nagant revolver type of system to hold the cartridge in place while firing?

a 30cal carbine in a suitable self defense loading in a j model might sell.

You could use a moon clip and have a magnet or something to hold the clip into place to keep the cartridges from jamming.

I don't know if it'd be good for anything, but it'd be fun to play with.

Already thought of the 7.62x25 revolver. Here is the thread where we discussed it.

Nope! All of the powder that is going to burn in a rifle case will do so in the first three or four inches of barrel. Pressure generated by expanding gasses is what drives a bullet down a barrel NOT not "burning" powder per se. you can get many rifle chambered handguns in cartridges from 30-30 to 25-06 even a .264 win mag. They're called T/C encores and despite being in short barrels they offer staggering performance relative to traditional handgun chamberings

Rifles for pistol cartridges have found a niche. Pistols
for rifle cartridges have not gone over, with few exceptions.

W.H.B. Smith's Small Arms of the World mentions that
they tested a double-action revolver in .30 carbine as a
companion arm to the M1 carbine. From a service length
barrel, 4 to 5 inches, the muzzle blast and flash were
considered too much to be practical.

The bottle-neck 7.62x39 also has a case tapered
specifically to speed ejection of the empty. With a revolver
you want the case walls to expand and stay in place in the
cylinder and not set back, to reduce friction as the cylinder
turns. Tapered cases set back (actually, lubricated revolver
cases or oily firing chambers give set back too).

Even the straight cased .256 Win bottlenecked revolver cartridge
proved not practical in the long run.

Arguments against bottleneck rifle cartridges in revolvers are
- excessive muzzle flash
- excessive muzzle blast
- loss of power compared to same cartridge in rifle
- cartridge setting back making it hard to turn the cylinder.

sorry,i meant why no 7.62x25 in a curently produced auto pistol.

the 7.62X39 SUPER nagant, with a trigger pull just under 1 metric ton

Rather get my revolver in .460 Weatherby Magnum.

+1.

About the ONLY ones with ANY success have been the .44-40, .38-40, and .32-20 (slight bottleneck), .30 Carbine Rugers and some S&W K-22s converted to .22 Harvey K-Chuck. Of these only the .30 Carbine and K-Chuck develop serious pressures, and only the K-Chuck has anything like a sharp shoulder.

I believe that Tarus is or was making a .223 Remington revolver, so it could be possible.

Okay, well, scratch the bottle necks. I'll take mine in 600 nitro express. :D

Bottle neck, tapered case in a revolver is a loosing partnership. It has been tried many times. I will pass on the resulting POS.
