I had a long email correspondence with a fellow from Australia who installed a pair of Rifled choke tubes in a 12GA SXS. Then he regulated it like a rifle. He killed a lot of those big buffalo in the north with it. I think he was using Brenneke slugs.

I suspect that shotgun chokes might be a bit too short to work well as a Paradox with bullets. If it was a barrel with plenty of metal in it, I believe you might get better results by amputating or reaming out the choke, and cutting full-length shallow, slow-twist rifling.

That shouldn't deform birdshot in this age of shot-cup wads, and while centrifugal force would widen the shot pattern, it shouldn't produce a doughnut pattern. The shot are spinning in a smaller diameter spiral as you move inward from the outside, and the ones in the middle aren't spinning at all.

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.

Here's the H&H ledger sheet:




Here's a photo (top, obviously):




Some bullets:




A few loaded rounds (225 grains 2F, 2 ounce bullet):





Kaboom! A right and a left:

Anybody want to give it a try?

WBLDon, rifled chokes can still be had as I just last week bought a pair for my CZ 12ga hammer sxs. They are made by Carlsons at www.chocktubes.com I do know that in the past they would do custom work...maybe even on a 10ga, but as CptCurl said the paradox barrels were quite a bit heavier than a shotgun. I owned a nice Hollis with the invisible rifling and it's barrels were somewhere near 0.95 to 0.125 as I remember....shot a Fosbery style slug of about 700 grains with 26grains of 4756 to point of aim each barrel at 75 yards

Looking at curl's muzzle I think the twist rate is steeper than the Carlson 6" rifled extension--and I get lead smear big time unless I shoot slower slug loads than the 1350-1600 fps factory offerings I see out there. The slug is just moving too fast by the time it engages the rifling. I even see it on my 20" barrel with 6 inch rifled extension. I don't know how the paradox could fare much differently given those factory speeds. Fully rifled barrels avoid the problem in the first place. (strangely, the best slug performance I get is with an ancient BBF over under combo with no rifling at all in the shotgun barrel--but it shoots a 2" group at 100 yds with the old Activ slugs, and the same group two inches farther to the left with the classic Brennekes. Good luck!
