5.7?
.327 Federal Magnum is under appreciated. Over 2000fps out of the Henry lever action. A Redhawk Ruger sized cylinder could hold plenty. Rimmed for your pleasure when it comes to revolvers IMO. |

As a general rule, round guns and bottleneck cartridges don't get along. If they stick in a revos cylinder, why don't they stick in a "normal" chamber? |

They have more of a tendency to back out and stick is the problem. Locks up the cylinder

Why not? After all there is a 45acp revolver. Not sure why, but they exist. |

It’s been done before. S&W Mod 53 in .22 Jet.

It had a lot of issues with the bottleneck cartridge and at a much lower pressure and velocity than the 5.7 |

That’s close and it’s a valuable contribution to this topic.

Look up the ill fated Model 53 S&W in 22jet.
That was a smooth tapered round, 357 necked down to 22 if I recall correct. And even it had problems with binding up against the recoil shield. Bottle necked cartridges like a 5.7 would be a bitch once the round pushes back against the recoil shield. I missed out on a Model 53 about 20 years ago. Was in oristine shape in box with the inserts to shoot 22lr. Wanted like 550 for it. I went home to research it and it was gone before I could drive back to get it. Would have been a fun squirrel popping side arm for out and about. /edit Glad somebody beat me to it. All of the above in the pic demknstrates the bottle neck problem. 357 down to 22 was done over a very lkng taper. A 5.7 with steep angle will set back like a son of a bitch. |

In this day and age, 3D printing sabots and reloading seems to make more sense than a bottle neck cartridge in a revolver

On firing sleeve slides forward creating seal at barrel/cylinder gap. Made for a hell of an effective suppressed firearm. Giant integral suppressor for the 30cal subsonic projectile. They made a smaller 38spl casing that fired 22 caliber bullets as well for a suppressed handgun version of the rifle. |

The thought of a 5.7 revolver makes my ears bleed. A .22 mag revolver is obnoxious enough, can't even imagine a 5.7.

7.8mm at the base, about .30". I'd guess 6, but I don't know how much meat that cartridge needs between the chambers. Mind the gap, lol! |

Depends on the size of the cylinder Then again: with a cartridge as thin as the 5.7, maybe there is extra room in a revolver’s cylinder? Like this: 
Or even the 3 barrel configuration posted on page 1 by Beitodestrafe. |

Quote HistoryQuoted:
A 9mm revolver could be built with a shorter cylinder and shorter frame than a revolver built for the needlessly-long .38 Special.
Getting back to 5.7: it is a long cartridge for a semi-auto. But not that long by revolver standards. And not much thicker than the .22. Plus, a .224 barrel with a Scandium outer shell would weigh next to nothing. |

Bottle neck cartridges are a pita in revolvers. .22 jet is awesome but gotta keep very clean or you end up with stuck cases and cykinder The 5.7 might work. Don't know how an extractor would work short of a single action though. |
