I tried to help answer your question:

Why can't I use {BLACKHORN209} in a plunger style muzzleloader?
The answer to your question was there. Blackhorn209 isn't reliable in leaky systems, and on some guns there are fixes on others there are not. I never said I offered a fix for your particular gun.
But like Michiganmuzzy said...
"Take all possible safety precautions and give it a try. Maybe it’ll work out for you. Maybe not. The possibility of injury to your face and hands is there. Be warned, be careful, be recording it so we can see how it goes."
Best wishes.
