If you can find one, a steel-cased 45 ACP makes a great wad cutter to make those over-shot wads. Drill out the primer flash hole so you can poke a nail in and shove out the cut wads, sharpen the mouth of the case and you're done. Just set it on a sheet of thin cardboard (tablet backing or wax milk carton is ideal) and tap with a rubber mallet. Do three or four, then shove them out with the nail.
I use three wads over the powder, then the shot and a single wad in my non-capsule shot loads. Then run a ring of hot glue to seal. But that was before those capsules were available.
BTW, I've also used regular .410 shotshells cut to cylinder length for 45 Colt shotshells. Works great in Uberti guns, but they won't chamber in a Ruger due to the rim diameter.
