No personal experience, but I've read that there's a tendency for the ball to come loose from a plastic patch and move forward in the barrel. Not a good thing.
you know, i have a whole bag of those plastic patchs from 30 years ago.
i dont think you can buy them anymore, i dont know.
i never had ball come out but i bet they could.
i could just see that, there comes ole mossy horns and i shoot and i sting him in butt with a plastic patch.
