I'm not addressing the specific functionality and safety issue of shooting a PRB out of a rifled choke "tube". But I have read about something that was designed and based on a similar principle. It was called a "Paradox Pistol" made by a man named Bowen, and it was based on a reworked Ruger revolver.
It only has rifling near the muzzle, and can shoot bullets, cartridge loaded balls and pistol cartridge shotshells well. There was an article and testing of it in a major gun magazine in the last 10 years. And the unpatched round balls shot very well although only engaging the rifling just before they exited the barrel, and the bullets did too. The term paradox refers to solving the problem of having one barrel shooting all the different style projectiles reasonably well, and how to accomplish or solve that problem. The partially rifled barrel was the solution, and not the problem.
While the gun below isn't the same Ruger revolver that Bowen designed and created, and which was written about and tested, I believe this commercial version is based on the same principle.
