For me, on the Traditionals, it's the history and yes, romance !!! I also like working with primitive weapons, in generals and use to make my own bows and arrows. In school I didn't do well in history and really into it, now. Yes, I too like the smoke, recoil, putting a good shot-string together and working on all aspect, including the leather, running lead and making horns as well as flasks. ...
On MMLs, teaching and noting else. ....
In regards to M/Ls as well as other things, there are those that touch your heart and M/Ls, does it for me !! ...
Be Safe !!!
