Hey guys. I had a friend ask me if his single barrel .410 with a fixed full would be safe to fire tss through. I figured yes but second opinions don’t hurt. Also he has a .410 Remington 1100 with removable chokes that do not say that it is ok to shoot steel through. I’m just wanting to verify if it is safe or not. Also note tss is 3”, #9, 1100 fps
