Think about what you are asking a " Rifled Choke Tube to do. In a rifled barrel, the rifling spins the bullet as soon as it moves in the barrel. In a Rifled Choke Tube, the bullet is traveling at a fast speed when it first enters the choke tube. Its like a race car going at 200 mph and entering a sharp curve. Except the car is made of soft lead, and doesn't have rubber tires to help it make the turn.
The use of a soft " sabot " allows the much smaller in diameter slug to enter the rifled choke tube at speed, with the sabot taking the torque of the twist of the rifling, while allowing the energy to be transferred to the bullet more slowly. If the sabot spins faster than the bullet, the friction created grabs the bullet as the sabot expands, acting like a car brake grabbing a brake drum. The bullet reaches the rate of twist rotation very quick. while the sabot takes all the torgue stresses. You can not achieve that when using a PRB or lead slug of bore diameter.
Now, some of those stresses are transferred to the barrel. If the barrel is thin walled, and round, it is not going to take the torque very long before troubles begin to show. However, if the barrel is thicker, as is seen in some shotgun barrels where the gauge chosen, say 20 gauge, is put in a barrel with the diameter of a 12 gauge shotgun, leaving much more metal to absorb torque. If the rate of twist is slowed, on a rifled choke tube, and the tube is made the same thick diameter of the harrel, with the rifled portion in an extension beyond the normal muzzle, it would be possible to create a rifled choke tube that would handle rifled slugs, or PRB. A 12 gauge bore on a 10 ga. barrel is now being done. Whether you can get extended choke tubes that are rifled for that particular gun I do not know. And I doubt that much work has been done to find the proper ROT for such a rifled tube to handle PRB, or conicals. If someone knows more about this, I would surely be interested in hearing about it.
