All I can say is how pathetic. A shotgun is a shotgun, even if it's a "Brazilian knock off". It will shoot a shell, if it fits. AND DONT USE A TOO LARGE OF A SHELL. IT IS ETCHED ON THE BARREL HOW LONG A SHELL IT WILL FIT!!!! Go to your mentor Greenhorn and ask him if he knows what he's doing. Sounds like he doesn't.
