Well, it would appear that, just as with any hobby, there are multiple levels or facets to shooting BP. Me, I just enjoy the doing it all in one shot (no pun intended), loading, capping (in my case) and shooting, then the huge puff of smoke. That's what sets it way apart from smokeless guns. To others, it's about duplicating a part of the past. That might be hunting with a flintlock or it might be living off the land for a week as they did back then. It's all good.
Concerning reenacting, I was invited to join a Civil War unit. When I asked about how it goes, they said, well, you can come in as a private or such but, if you have a horse, etc, you could be an officer. That sounded EXACTLY like the Civil War - no thank you, please! Maybe I could be one of those guys who paid for a substitute, too. :grin: On the other hand, there were a couple of guys shooting at the range (only BP burners there that day) and they had large straw hats with black grosgrain ribbons emblazoned with CSN. Yep, Confederate Navy. Very relaxed and in it for the fun. Would have joined that group but couldn't travel extensively at the time. So I guess it all depends upon what suits you.
FWIW, about the best way to get the sport to grow is to let a smokeless shooter have a shot or two next time you are at the range.
