I understood that you were running a copy of the Omega plug, i have modified a couple of those also adding a Lehigh vent liner. And then I went back and altered another one by putting a ventliner in and then drilling it for a 25 acp cartridge. The 25 acp using a regular small rifle primer ignites BH also without a problem good weather or bad weather...
This is the one that drilled out for a 25 acp
