I may join in on those someday. My only 1873 rifle is at a shop now, getting an action job; but that looks like a bunch of low-stress fun. Not sure about the clothing, though. I’d have to come up with something along those lines.
It is low stress fun, compared to the 3 gun match that I shot last weekend, other than my shooting buddy, the average age of the shooters was 30 years younger than us. There is probably a reason that since Sunday afternoon she asked the question, "aren't you getting a little to old for 3 gun", TWICE!
In Cowboy Action depending on which category you choose you can either go a minimalist outfit, or if you choose "B Western" you can go whole hog and drop a lot of coin. I either shoot "Wrangler" or "Silver Senior" these days, category dress code means boots, plain long sleeve shirt, jeans and a hat. So if I feel lazy I don't have to go crazy unless the wife wants to pretty me up.
