This is a pretty simple idea and hopefully my description will suffice. Hopefully it will be better than nylon panty-hose.
I scribe a circle on a 3x5 index card that measures the interior diameter of my bore or the point of its tightest choke.
I scribe a second, outer circle using the same center point. The distance of the second circle will be determined by the amount of shot you want to pour. Experimentation will determine this.
Now, I cut the card on the outer circle line. When it's cut out, I make quartering cuts from the outer circle's circumfrence to the center circle line. Then I make eighths the same way. Now, I have a small circle with 8 wings that are slightly delta shaped.
Make a bunch of those.
When you've loaded your powder and over powder cards, work one of these into the bore so that the wings begin to overlap each other, leaving the inner circle flat on the bottom. It may be slightly bowl shaped, but that will flatten out when you seat the charge. When the edge is flush with the muzzle, pour your shot into the cup and seat it.
When it exits the bore, the wings open up and the shot is away. I've never had one burn on me, but you might look out in a fire prone area.
The card can be lubricated too.
Another way to make the cuts are at an angle to the center circle. When the flaps overlap, they sort of form a spiral. I haven't seen an advantage either way.
