I didn't get any money from Remington, just a blizzard of unintelligible paperwork for a few years. I have a few Remington barrels from the 'defective' era and they seem to work just fine.
The Polychoke story is interesting. It appears to all the world to be made of spring steel. It would also appear that the hardness necessary to make the leaves of the collet retain spring action would make the Polychoke harder than any steel pellets.
My initial concern with steel shot in a Poly was that the increase in pressure might fail the soldered joint. Poly install jobs vary widely. Some are good and straight, some point off at an angle, and some have a pretty wide gap.
The gizmo was really ahead of it's time. The only problem except the appearance of the thing is that it raises the front bead on plain barrel guns and makes the gun shoot low. Works better on ribbed barrels, or you can bend the barrel (which can and has been done).
