So why not a bottleneck cartridge in a revolver?

Me too! That round is TOO cool!!
The trouble with 7.62x25 is the same as with 9x19 or any other rimless round in a revolver. Unless special provision is made so moon clips can be used, or the extractor is made to handle the rimless case, extraction on a conventional DA revolver is difficult.
Now, in a single action type with an ejector rod, either cartridge is perfectly feasible, and Ruger has made revolvers in both 9x19 and .45 ACP.
There is absolutely no reason bottle necked RIMMED cases won't work fine. The .22 Jet, with its long taper was a poor design from day one and I never understood the rationale of the designers. Other rimmed and bottleneck cases have been used in revolvers just about since there have been cartridge revolvers.

How about necking down a 44 Rem Mag to accept a .308 bullet? Should work in most revolvers and ballistically it should perform great.

Since the gun cannot have a bore in excess of .50 inch, bottlenecking would allow for much more powerful handguns than the Smith & Wesson X frame .500 Magnum series, with the cartridges necked way down to a mere .50 inch from a base diameter of perhaps 1.00 inch. Rubber grips would be a good idea.

I would love love LOVE to have a classic revolver say a model 28 customized to be able to shoot .357 sig. Then I would simply show people the revolver and brag about it and watch their heads explode from rage.

There are plenty.
Here's a 30-30 BFR

Did anyone else see that Freedom Arms is offering an SA for the .224-32 wildcat?
It's a .327 Federal brass necked down to .223, and it takes 40gr spitzer bullets. Here's the PDF flier about the new cartridge:

I assure you this is not a MYTH
I have a BFR in 30-30 and I can attest to cylinder binding from case setback. After a while I found that I could practically eliminate the problem by fastidiously keeping the chambers free of any oil. When I clean my BFR I actually punch the bores with an alcohol soaked patch.
If such a low pressure cartridge can cause this much fuss imagine the problems a truly high pressure loading would have.

You could get a smith with a well equipped machine shop to make one on an L or N frame. It would not be cheap and I am not sure how much you would grain over some other hot loadings in .30 caliber. The nagant has been rechambered to 7.62 x 25 and does apparently function untill the cylinder goes kaboom.

Already exists. Get an old Colt or S&W in .32-20 and you have what amounts to a rimmed version of the 7.62X25, with identical ballistics.
Or, if you want a straight walled version, get a .327 Mag.
Unspellable is correct. There is nothing inherently wrong with bottle-neck cases in a revolver. The badly designed .22 Jet probably soured the public and the revolver makers on all bottle-neck cases, but it shouldn't have.
Real problems are that most bottle-neck cases are rimless, meaning that a revolver would have to have some means of ejection or use clips, and that more powder and smaller bores add up to more erosion at the cone and more gas cutting of the top strap.

The problem is this: In a normal revolver, the primer blows out -- moves far enough back so that it contacts the recoil shield. Then, a fraction of a second later, the case moves back and re-seats the primer.
If the case is cylinderical, or nearly so, there isn't much of a problem. But if it's bottle-necked, the shoulder then moves forward, until the case fills the space from the recoil shield to the shoulder of the chamber. In effect, it does exactly what a rifle cartridge does with excess headspace.
In severe cases, the case can split or the head can seperate. But what usually happens is the now-longer cases rub against the recoil shield as the cylinder revolves and ties the gun up.
The reason keeping the chambers free of oil and combustion products helps is that it makes the case adhere to the chamber wall and tends to limit backward motion.

What happens?
Vern is partly correct. On firing the primer does back of the case and then the case does set back on the primer. It will set all the way back on the primer with any reasonable load. It is part of the job of the brass case to spring back and free things up when the pressure falls off. If it doesn't, it's because of excessive pressure, bad batch of brass, or poor case design ala the 22 Jet.
I shoot the 17 HMR and the 357-44 B&D with out any set back problems.
The 22 Jet's inspirationg, the 22 Harvy K Chuck had no set back problem. Other bottle necked cases used in revolvers in the past with out set back problems include the 38-40, 44-40, 32-20, and 7.62 Nagent. Current revolvers use the 22 Hornet, 218 Bee, and the 9 mm and 30 M1 which are tapered rather than bottle necked. I've not heard of problems.
Point to remember. Case set back would tie up a break action rifle just as much as a revolver. The list of bottle necked cases used in break action rifles is way too long to list here. I have a break action rifle using a bottle necked case.

not a valid comparison
think about how much more leverage against the chamber a break action has with the piviot several inches forward & outside the chamber and several lbs of barrel sticking out there vs a revolver with a tiny pawl less than a quarter inch the wrong way for mechanical advantage
