The 40 mm breachloader went together so well it gave me more ideas to try . I want to try a barrel set up like the british 10 lb screw gun, so it can be broken down from a 260 lb barrel into 120 lb, 78lb ,and 64 lb sections. Also the pawn stars had a signal cannon on a while back that had the case attach to the breach screw . It was installed and ejected with the breech screw ( no breech ring to mess with ). Hope to finish it by New years eve .
