There are some clubs that do not have stage fronts, and really require you to know your firearms as far as where they hit. Kansas Vigilance Committee comes to mind. Smallish targets set a bit farther out. Their big spring shoot, The Jerry Barnes 2-Gun Regional, is coming up beginning of May. (And as the name implies, they don't cotton to the notion that everyone ran around with two revolvers, a rifle and a shotgun back then.)
People travel from Iowa, Texas, Nebraska, Missouri, etc. to make this one. Good times and period correct people. They also do stages that are a modified "woods walk" that bedevil the older, less limber set.
It's like that box of chocolates, you'll never know if you'll be shooting prone sometimes over the carcass of your horse, out of a wagon box, with a wounded arm . . . Plus, they hold the NCOWS National Double Action shoot on Sunday. Lots of double actions in people's gun safes that need to be given an outing.
Grand Army of the Frontier has really challenging "woods walk" stages, and you can load off your body, and is offhand. They have a category that basically allows cowboy guns. Primitive camping, good food prepared period correct. The Grand Muster is coming up in June at Sergeant, NE. Go down to The Barracks forum and read the stickied post. Again, lots of people travel, even some distinguished gents from Canada, to attend this. Great people and definitely something out of the ordinary as far as shooting pleasure. And there are many NCOWS folks who hold dual membership in both organizations. (And best of all, the GAF membership does not cost a single greenback!)
As far as NCOWS categories, visit the NCOWS website and read over the info there. You can basically pick a category to suit your firearms, choice of powder, gender and preferred hold (duelist or shootist).
Those videos of the mine cart were taken at West Side range in Evanston, Il. They have been kind enough to host our National for the past 8+ yrs. Great range and wonderful people. They put a lot of work into making that range work, and they also have a SASS club within their membership. Their range is set up for how they like to play the game. Other NCOWS clubs have different ideas, so the style of shooting you like might be hiding at another club's range. If you can, get around to visit and shoot at as many different NCOWS clubs as you can to see all the different ways it is done.
