I shot the Suomi today. About 60 rounds total. I still have a few more mods to make to it and a new two stage recoil system before I weld it up and remove the bolts/screw holding on the barrel bushing and jacket. It was pretty sweet to shoot, no recoil to speek of. You could watch where your bullet was hitting because the sights didn't move much when you shot. I need to order the drums now!
