The first thing that comes to mind when I see one of these coming my way is..........PUT A SHELL CATCHER IN THAT THING!! I don't want your hulls bouncing off of my gun when we're shooting trap and I'm on 5 stand and you're on 4................................ I was shooting in Florida and some guy was on my left with an A5. One of his hulls bounced off of my barrel. I spent the rest of the round hunkered over my gun trying to protect it. It wasn't long after that hull bounced off of my barrel, that I was hunkered over my gun- protecting it and one of his empties landed in my left hand that was down at my side. I caught it and stuck it in my pocket. After the round was over I went over to him and gave him back his hull and told him that they DO make shell catchers for those things. His remark was, "Uuuuhhhhh, shell catchers??"
