A 16g or 20g fiber wad or "wooly" wad may work to fill up the bottom of the shot cup too. Seat it first then drop your shot. I do that in my 10g reloads. Works like a charm.

I do understand your question though. Why would that load be published if it doesn't fill the hull? Maybe they forgot to add the filler wad to the recipe would be my guess?
