You're talking about strict rendezvous Ron. Those guys are over the top. I wasn't talking about those, and would never go to one.
I'm talking about the average black powder shoot. It's just a shoot, but they try to simulate an early 1800's shoot. You can dress up in period clothing if you want to, but it's not required. About 75% do.
There are rules to what you shoot though. PRB only, no peeps, No FO sights, BP is wanted, but some will use Pyro. Sidelocks, blued, wood.
I like PC, but not HC. HC is what the picky guys want, and will check your buttons. PC is just period correct. If the gun you're using used it, then so can you. I don't want to make believe i'm living in 1840. I just want to use a similar weapon as close to the original as possible. Then carry it further by using everything else related to shooting and loading the gun as possible to the era. Powder horn, fixed powder measure, cutting patches at muzzle etc.
That's my definition of a traditional. Whether it's shooting at a range, hunting, or a forum.
You may not agree, but it doesn't matter to me. It's my definition.
