I would personally like to work with a rifled choke tube, however none of them have deep enough rifling to be as effective as they could/should be, I am certain.

To take a projectile that is bore size, non-rotating, moving at well over 1,000fps, and upon striking the choke, rotate it to stabilization rpm in just 2 1/2" or 3", will require significantly deeper rifling than the .005" or .006" that most of these tubes seem to have. I am not certain the barrels of modern guns (outside the threads) are thick enough to withstand hitting them from the inside with something that is virtually .040" to .060" oversize, .020" to .030" per side (if made to original specs).

To absolutely rotate the ball or slug is why the original paradox guns had VERY deep rifling ie" very tight choked sections.

In my humble opinion, of course.
