Not a problem at all, Eric. Just don't want to answer questions not asked. :wink:
The short answer is no. CAS events are typically for two pistols, one rifle and one shotgun. There is a movement in NCOWS called Working Cowboy and it uses one pistol and one rifle, with staged shotguns, when used.
Of course, there are a lot more folks out there shooting cowboy guns, so you might be able to find others who want to shoot your way. Good luck.
Adios,
