I just use the Star plastic ring caps for cap Guns. Pick out the white insert with a pin. This leaves the priming compound in the little red cup. Dribble in a little Black Powder till the cup is about half full. Then compress gently with say a match stick (that prime compound is pretty volatile).how do you get them to work?
Give the cups/powder a good spray with Hair Spray and let dry. I use homemade BP and the cheapest Hair Spray I find (I'm not sure how substitutes would go).
Don`t push the caps onto the nipple, sort of roll them on from the side and don't push down firm, let the hammer do that on firing. Carry a pin with you to remove the little plastic plug that sometimes gets stuck in the top of the nipple after firing.
My honest appraisal is they work as well as bought #11`s I have used many Hundreds over the years. On the odd time they have not set off a load re trying with a CCI #11 has still not set off the charge and I have had to put powder into the channel.
