Sumtoy had the 562 pegged for the Fed #7 HW way back when. The five wad catcher rings to boot. The main problem with the design of the ported I C choke is that the number of ribs weaken the choke to the point whereby a stiff collar or sleeve passing through can tend to spread those ribs.
The ribbed IC choke is still an excellent choke but just not designed for that type shell.
The old Hastings chokes were non-ported and had no wad catchers and came in 562 as well.
