for information on loading the Paradox load have a look at the rear section of Greame Wrights book "Shooting the English Double Rifle". There are some loads listed with pressure date. The 720 grn pojectile works a treat in My H&R with AP 70. With open sites, shoots under 2" at 50 metres. I ma looking for a heavier barreled one now as this light one really jumps. With a 720gns slug at 1100-1200 FPS it takes a lot of stopping. A friend of mine tried it on a pig from the rear and it came out the chest and kept going. Dead pig. I have not tried "Rifled slugs" in mine but have tried some balls, but not quite accurate enough.
