Interesting concept for sure, but it would be a challenge to engineer. Forcing that slug through the barrel is going to introduce a significant torque on the sleeve. You would need a keyed/threaded sleeve of so sort, which would reduce the reinforcement on the larger caliber, increasing the risk of bulge/rupture. You would almost need one sleeve for each caliber.However, the rifling would be in the sleeve/tube itself. The insert would be both a chamber adapter AND a short rifled barrel section.
Yeah, only longer, in a longer-cylinder wheelgun.
Maybe have a thin groove in the cylinder connecting each chamber and the adapter be one piece and lock in the groove. Kind of like a toy cap gun.Interesting concept for sure, but it would be a challenge to engineer. Forcing that slug through the barrel is going to introduce a significant torque on the sleeve.

Before going to that length, I think I would make the barrel threaded like a rifle and just use smooth sleeves in the cylinder.
how about going to 45acp on moon clips,load the adapter as a unitImagine a gun like the Taurus Judge, but with the cylinder a little longer.
Maybe 4" length on the cylinder, and a 1.75" barrel in front of that.
The standard caliber would be .45 Colt/ .410 shotshells.
But you could stick sleeves/ liners into those five big chambers and then use the revolver with .38 / .357.
Or 9mm.
Or, for training newbies who are noise sensitive and recoil-shy, .32 (either ACP or S&W long).
For any of the sub-caliber rounds, they would not ever touch the gun's own barrel.
The barrel would be like a "bloop tube" on a target rifle. Or one of those 6" long flash hiders on an AR. The bullet passes through it without touching it.
However, the rifling would be in the sleeve/tube itself. The insert would be both a chamber adapter AND a short rifled barrel section.
You could also have a .38/ .357 SHOTSHELL-ONLY insert that is smoothbore, to use CCI's blue-capsule shotshells for pest control and practicing on moving targets thrown into the air.
Even if the "barrel" on the gun itself would not do any good other than increase sight radius for the .357 or smaller-diameter calibers, there would be 2.5" of "bore" in each chamber insert to boost the velocity and stabilize the bullet for accuracy. At least enough accuracy to train newbies how to hit a man-sized target center of mass, or knock over old Coke cans at 7 yards.
