Most every SASS or NCOWS club has allowed me to set up/shoot a "Military" class. One GAF spec rifle, one GAF spec revolver, cas spec loads, shoot their course of fire with GAF guns reloading as needed, ignore the shotgun targets. Its fun and great practice, and folks notice and ask questions. A Krag and a DA revolver get a lot of questions from the CAS crowd. If you use a single shot like a trapdoor you shoot half the rifle shots. IE they shoot 10 you shoot 5. (You shoot bullets twice as heavy after all) My local SASS club now sets seperate targets out just for the GAF shooters, IE further back against the Berm.
