a few years back i purchased the flyway edition 835. Over the last couple of years i have shot alot of ducks. The gun patterns great for this but the last few times i shot lead shot it would not hold a pattern. Has anyone else had this problem? Is this problem common with using steel? I would like some opinions on what to do. i like the gun and would like to fix the problem. Is the solution in changing to a new choke tube or a new barrel or both? Or maybe it would be better and cheaper to get a different gun to shoot lead. Any one got an opinion on this?
