Default Re: Civil War Pinfire "Chimney Adapter"

Interesting adapter!!
I would imagine that there was quite a bit of "blow-back" as the steel wouldn't expand to seal the chamber like brass does. The closer the fit, the less blow-back, but, also, the sooner the chamber would crud up and make the devise harder to get out and re-insert.
