DD thanks for the clarification on the BP/Flying issue. I was pretty sure that was correct; but had begun to doubt myself. When I asked here, I got further confusing data, so I checked the TSA website, specifically looking for Substitute issue. I totally agree that parties beyond the passenger rarely "KNOW", they typically just make uninformed decisions based on ignorance and prejudice. My concern was inflamed when I began seeing TSA doing "wipe downs and sniffer tests of firearms cases (and asssssuming there were similar test of stored luggage).

Im not opposed to other cartridges and the Number 2 Musket sounds great. My big draw for the 577-450 was that I had dies and brass BUT since this is a ground up project, Im open to new ideas. I'll talk to my smith and get back to you

Regarding the shotgun action, I was looking at a Greener that didnt appear to be split. It was definitely a 12/14 ga action (3 prong firing pin). Its more than possible I missed the split but I was looking for it. It was a stripped action, would the split not be visible without a barrel?

THankx again
