I traded for this beautiful 20ga Rizzini sporting clays gun. When I shoulder it, the beads are lined up perfectly. It feels great in my hands, has a great trigger, etc. Yet somehow I can't hit anything with it. I have now shot three games of clays with it on different days, and I'm shooting a good 10-15 birds below my average with it! It's going to be a shame to get rid of the thing because it's so pretty, but I'm at a loss. Anyone else ever experienced this?
