Hi Mickey,
from my own experience, I can tell you that Wicke Amorces won’t work in „closed“ modelgun systems.
They don’t have enough power to cycle a modelgun.
Maybe you need to build a cartridge for 2 Wicke Amorces but then the punching power to ignite them could be a problem (the Japanese plug fire caps are more sensitive then the Amorces).
I think only in revolvers, shotguns and other non-automatic modelguns, where you only need a bang and some smoke without mechanical movement, they could do a job.
