This is a very interesting topic. I used to be in the camp of "let's go to a Rendezvous get wild, chase girls and get drunk!" I had a Muzzleloader and did shoot it but I usually missed the rendezvous shoots because my buddies and I were up all night drinking and getting rowdy. This was the late 70's. Most of the guys were wearing orange buckskins, a 3" belt with a Green River knife, a Capote, one of those hair pipe chokers, some kind of fur hat with the head in the front, Dyer's moccasins, and shooting a "Hawkins" (not a Hawken) rifle. Everyone had a "Possibles Bag" (Not a shooting or hunting pouch mind ya!), a powder horn, and a medicine bag. Now that I look back I realize we were all very influenced by Hollywood and we looked pretty ridiculous but you know what we felt like "Mountain Men" by God and we had fun!
Fast forward to today there's less "rowdy" drinking and girl chasing and my interests are in building and hunting with muzzleloaders, attending NMLRA shooting events, and the history is more important to me now but it depends on where I'm shooting. I'm into learning about everything from French and Indian war, revolutionary war, the Long Hunters, the Frontiersmen, Explorers and Settlers of the 18th century. I enjoy reading and doing some research and trying to improve my understanding of how the world looked to people back then, how they lived and died, hunted, dressed, survived and thrived. When hunting or tramping around in my woods I like to experiment with my guns, accoutrements, tools, and clothes that I have made or acquired. I know my kit is not perfectly PC/HC but I don't really care as long as it simulates an experience that I enjoy and can learn from. I don't consider myself an expert, but I like talking about the subject with like minded folks.
So I guess I went from the "Rowdy Rendezvous" camp to the,.. as you said
@Bob McBride "history buff who’s primary hobby is shooting" camp.
As far as what others are doing is up to each person to decide. I won't judge! You can be a stitch counter, just count your own and don't be a eyeball'n ma footwear choice and tell me "it's wrong for my persona" or you might find out my "persona" will lift yer hair!
