Why not get several boxes of commercially loaded CCI shot shells, stick a fork in it and call it done. They are plentiful in my area. Or purchase some Speer shot capsules as components and load them yourself with #9's. Speer provides load data for their capsules.
I use the plastic shot capsules to make .45 Colt shot shells and I have also used the shot capsules in auto rim cases to make snake loads for my model 25 in .45 ACP.
Used a .45 ACP taper die to taper crimp the plastic capsules and all were successfully crimped with no breakage. Loads are as effective as commercial ones, and both cheaper & simpler than trying to dick around with .410 hulls.
