These are the ones I was referring to, and they work as advertised...from the Circle Fly website:
".....Pre-Lubed Wads, 500 count bag. Shotgun sizes, We use the standard ½” fiber cushion coated with our own lube for these wads, and they are designed to keep black powder fouling softer, and your gun cleaner.
We are able to coat the outside of the wad, and keep the centers dry. This puts the lube where it is needed, and keeps the wad as light as possible for the best patterns possible....."
