Rusty Gun,
If you insist on the need for a card on top of the powder, How do you know the card is lying flat on top of the powder and not jammed in sideways?
I think the wad would be better than a card as that posture on the powder problem would be eliminated.
If you really want accuracy, get a micrometer and fine tune your regular shooting patch.
{ would have written nothing if it weren't for the discovery of what fine tuning your patch thickness can't do to tighten your groups.
