I believe I have read that the ball/bullet to be fired in a Paradox gun should be a relatively loose fit in the smooth bore section. when it's fired, & hits the rifling section, could that initial contact with the fairly chunky rifled end kinda grab & slightly pull the gun away from the shooter,reducing recoil...theoretically ,at least  franc

Short answer, "No." It is a momentum thing, IMO. If the slug were to decelerate, even a small amount, there would be a gas hammer behind it and a bulged barrel a distinct possibility. Total recoil is, of course, dependent on ejecta weight and velocity. Said momentum is translated to free velocity of the recoiling gun, depending on its weight. Said weight and velocity of the gun give recoil energy. "Felt recoil" may have to do with instantanious acceleration of the ejecta. That is, the shooter "feels" the rearward acceleration, or maximum acceleration, as opposed to the total recoil (that ought to start a debate!!!). Anyway, I dn't see how ejecta can "grab" the barrel and pull the gun forward.

Could it be that a bullet spends so little time in a barrel once the cartridge is set off that the shooter can't tell if they're feeling maximum acceleration (bullet still in the barrel?) or 'recoil energy'. Maybe, for the shooter to 'feel' recoil, there has to be some acceleration, or force. Wouldn't the gun stop recoiling once the velocity of the 'ejecta' stabilized.
I recall a short article about a Marlin lever gun had six or eight bullets lodged in the barrel. I believe the shooter said he felt no noticable recoil and only heard a low muffled sound every time he pulled the trigger. None of those bullets cleared the muzzle, but if maximum pressure was developed in the chamber or just in front of it, those bullets developed some maximum acceleration and then of course deceleration.

My Ithaca 37 smoothbore bird gun with rifled choke and Lightfield Lites will shoot cloverleafs at 50m. With Foster type slugs one is lucky to hit large milk jug consistently at that range.

It would be "Extremely" doubtful with that many bullets stuck in the barrel, especially as you did not mention a bulged barrel, that any of them reached maximum breech pressure. Sounds as if he had some bad ammo of some sort, which did not reach maximum acceleration.
I do not believe that an un-bulged barrel is a guarantee there was absolutely no check to the projectile, but simply there was not enough check to produce a bulge. The severity of the hammer would of course be dependent upon the extent of the check. It would seem unreal that if the ball is large enough to be engraved by the rifling that at least a "Slowing of Acceleration" if not a slight check would indeed occur.

It one could convince Italians to provide rifled top barrel and folding sights on that Chiappa 'Triple Threat' deal they would have quite a gun. The "8lb" weight would take sting out of recoil as well. SxS barrels for bird shot/BK shot plus rifled barrel on top for sabot slugs for big game cool eh?

Paradoxes have less recoil than a fully rifled gun given the same cartridge charge and bullet weight. Holland took advantage of the reduced recoil by shaving 2 to 3 lbs off their big bore paradoxes. Paradox bullets do "rattle" (.001 under bore) to the choke where this is a .002 restriction just prior to the rifling There are 40 to 45 points of choke in the rifling. Two 8 bores. Both 10 dram 1250gr guns Paradox on the right.

Could it be that a bullet spends so little time in a barrel once the cartridge is set off that the shooter can't tell if they're feeling maximum acceleration (bullet still in the barrel?) or 'recoil energy'. Yes, this is the supporting theory for using total energy as the measure for recoil. Maybe, for the shooter to 'feel' recoil, there has to be some acceleration, or force. Yes, the recoil is manifested as force on the shooter. Wouldn't the gun stop recoiling once the velocity of the 'ejecta' stabilized. No, the recoil "stops" only after the ejecta exits the muzzle.
I recall a short article about a Marlin lever gun had six or eight bullets lodged in the barrel. I believe the shooter said he felt no noticable recoil and only heard a low muffled sound every time he pulled the trigger. I agree with 2-p that there must have been sub-standard ammo involved; like no powder, maybe. Otherwise, how did the powder gas pressure bleed off? Open the action on barrel pressure and you will likely get a face full of brass and gas. None of those bullets cleared the muzzle, but if maximum pressure was developed in the chamber or just in front of it, those bullets developed some maximum acceleration and then of course deceleration. I don't think this was the case. My take on this story. DDA

It would seem unreal that if the ball is large enough to be engraved by the rifling that at least a "Slowing of Acceleration" if not a slight check would indeed occur. I agree and would support the "slowing of acceleration." A gas hammer would occur only if you had a negative acceleration which produced a lowering of instantanious velocity.

[quote=PM]Paradoxes have less recoil than a fully rifled gun given the same cartridge charge and bullet weight. Do you have an explaination for ths lessoned recoil? Something other than lower velocity? Holland took advantage of the reduced recoil by shaving 2 to 3 lbs off their big bore paradoxes. Paradox bullets do "rattle" (.001 under bore) to the choke where this is a .002 restriction just prior to the rifling There are 40 to 45 points of choke in the rifling. Some serious extrusion going on in that choke section!!!
