It's a fool's errand to think you could cut Paradox rifling in the chokes of a 10b shotgun. The barrels aren't nearly heavy enough and there's not even close to the amount of metal needed at the chokes to do the job. A Paradox is not a shotgun nor is it a shotgun conversion.
Here is a photo of the muzzles of my Holland & Holland 10b Paradox to give you an idea of what's going on:

The 27" steel barrels alone weigh 6 lbs. 15 oz., with the gun coming in at 13 lbs. 1 oz.
