I've yet to shoot in a WB scenario, but I'd love to. I'm trying to get it off the ground locally. Most of us have the guns already, including military rifles of the era - Mausers, Springfields, etc.
It will bring out a lot of turn-of-the-century guns that don't often see the light of day - Colt NS, Triple Lock S&Ws, Webleys, Mauser Broomhandles, Lugers, etc.
I'm all for developing new aspects to the shooting sports. It's all fun. Let's hope it doesn't get beaten to death with rules upon rules and classes upon classes ......
I watched SASS devolve into IPSC in Cowboy clothes, disregarding the power factor utterly. Anyone who can tolerate SASS ought not to have issues with someone hanging onto a 1911 shooting GI hardball equivalent loads.
The open range west was effectively over with the advent of barbed wire. New guns were rapidly developing, overlapping the guns that won/tamed the west.
